Why I’m Completely Obsessed With This Pistachio and Raspberry Cake

I’ve made this cake four times in the past few months and I’m not even remotely sorry about it.

It all started when I wanted to make something really special for my mum’s birthday earlier this year. She’s not usually fussed about cake, but I wanted to surprise her with something a bit different – something that looked as stunning as it tasted. I’d been seeing pistachio and raspberry cakes all over Instagram and Pinterest, and they looked absolutely gorgeous. But you know what? Most of the recipes I found were either wildly complicated or required ingredients I’d need to remortgage the house to afford.

So I did what any determined daughter would do – I experimented. I combined techniques from various recipes, tested different methods with my own twists, and after a couple of trial runs (one of which ended up as “practice cake” for the kids), I created what I genuinely believe is the perfect version. The kind that looks like you’ve spent hours slaving away (great for impressing your mum), but actually comes together without too much faff.

The cake was such a hit at Mum’s birthday that my daughter then requested it for her 13th birthday, asking for “something green but not minty.” Since then, it’s become my go-to celebration cake.

The result? A cake with the most gorgeous vibrant sponge layers, filled with luscious pistachio cream and fresh raspberries, then topped with even more berries for a stunning but surprisingly simple finish. No heavy buttercream coating needed – this beauty is all about celebrating the natural flavours and colours. My 14-year-old, who claims to “not really like cake,” had two slices. My husband, who usually just picks at desserts, polished off the leftovers for breakfast (don’t tell him I saw). And my mum? She’s been telling everyone about “that gorgeous cake Emma made.”

What Makes Pistachio and Raspberry Such a Dream Team?

Here’s the thing about this flavour combination – it just works on every level. Pistachios have this gorgeous, subtle nuttiness with a slightly earthy, almost buttery quality. They’re not shouting for attention like walnuts or as assertive as almonds. They’re sophisticated without being pretentious (if nuts can be pretentious, which in my mind, they totally can).

Raspberries, on the other hand, bring this sharp, vibrant tanginess that cuts through the richness of the pistachio cream. And here’s what I love about this particular version – by skipping the heavy buttercream coating and just using light pistachio cream with fresh berries, you get to really taste both elements. It’s not masked by loads of sweet frosting. The pistachio cream is silky and delicate, the raspberries are bright and juicy, and together they create this perfect balance that feels indulgent but not heavy.

Plus, can we talk about how stunning this looks? Those vibrant green layers with fresh raspberries peeking through and piled on top? It’s the kind of cake that makes people pause before cutting into it. Very “deconstructed elegance,” if we’re being fancy about it. Which we’re not, obviously, but it does photograph beautifully.

When to Make This Pistachio and Raspberry Cake (Seasonal Tips from a South London Mum)

Living in South East London, I’ve learned that timing really does matter when you’re baking with fruit. British raspberries are at their absolute peak from June through August, and honestly, that’s when this cake truly sings. There’s something about those summer raspberries – they’re sweeter, more fragrant, and they don’t cost an absolute fortune.

That said, I’ve made this cake in December for a Christmas celebration (used frozen raspberries and it was still brilliant), and in March for Mother’s Day (slightly less colourful raspberries but no one complained). The beauty of this recipe is that it’s genuinely adaptable to whatever’s available.

Best times to make this cake:

• Summer celebrations (June-August): Peak raspberry season, perfect for garden parties, summer birthdays, or weekend treats
• Spring occasions (April-May): Lovely for Easter celebrations, Mother’s Day (I made this for my mum’s birthday earlier this year and she absolutely loved it), or baby showers
• Special celebrations (year-round): Birthdays, anniversaries, or whenever you fancy something a bit special

Let’s Talk Ingredients: What You Need and Why

For the Pistachio Sponge Layers

Pistachios (180g shelled): This is your star ingredient. I usually buy them from the bulk bins at Whole Foods or Sainsbury’s – much cheaper than those fancy packets. You want unsalted, shelled pistachios. I’ve used both raw and roasted, and honestly? Both work brilliantly. Raw gives you a brighter green colour, but roasted adds a deeper, toastier flavour.

Plain flour (250g): Good old all-purpose flour gives us structure without being too heavy.

Caster sugar (240g): Creates that tender crumb and helps lock in moisture.

Unsalted butter (200g, softened): Room temperature is crucial here – it should leave a slight indent when you press it. I take mine out of the fridge about 2 hours before baking.

Large eggs (4): These bind everything together and add richness. Again, room temperature makes a massive difference.

Baking powder (2 tsp) and bicarbonate of soda (1/2 tsp): Your raising agents that give you those lovely fluffy layers.

Whole milk (120ml): Adds moisture and tenderness.

Vanilla extract (2 tsp): Never skimp on vanilla – the cheap stuff just tastes like chemicals.

Optional: Green food colouring (1-2 drops): Look, I’m not usually one for artificial colours, but a tiny drop of green really does make the cake pop. I use the gel kind from Waitrose.

For the Pistachio Cream Filling

Mascarpone cheese (500g): This is the base of our luscious filling – it’s rich but not as heavy as buttercream.

Double cream (300ml): Gets whipped with the mascarpone for that silky, cloudlike texture.

Pistachio paste or cream (100g): This is what gives the filling that gorgeous pistachio flavour. I make my own (recipe below) or use a shop-bought version like the Sicilian pistachio spread.

Icing sugar (80g, sifted): Just enough to sweeten without making it cloying.

Vanilla extract (1 tsp): Enhances all the other flavours.

Salt (tiny pinch): Balances the sweetness beautifully.

For the Layers and Decoration

Fresh raspberries (600g total): About 200g between each layer, plus 200g for the top. Peak season (June-August) is best, but frozen work in a pinch.

Optional: Chopped pistachios (handful): For sprinkling on top

Optional: Fresh mint sprigs: Adds a lovely fresh touch

Optional: Icing sugar for dusting: Makes it look extra pretty

The Secret to Perfect Pistachio Flour (And Saving a Fortune)

Right, let me share something that took me embarrassingly long to figure out: making your own pistachio flour is ridiculously easy and saves you so much money. Pre-ground pistachio flour can cost upwards of £15 for a small bag. Making your own? About £4 worth of pistachios from the bulk bin.

Here’s exactly how I do it:

1. Get your pistachios: Buy unsalted, shelled pistachios. You need 200g for this recipe.
2. The blanching trick (optional but makes things prettier): If you want that really vibrant green colour, blanch your pistachios. Pop them in boiling water for 60 seconds, drain, and rub them between kitchen towels. The skins slip right off, leaving you with brilliant green nuts.
3. Blend carefully: Here’s the important bit – pulse your pistachios in a food processor in short bursts. You want a fine, flour-like texture, but you need to stop before it turns into pistachio butter. I do 5-second pulses with breaks in between to check the texture. Takes about 30 seconds total.
4. Don’t over-process: The moment you see it starting to clump or look oily, STOP. You’ve gone too far and you’re headed for pistachio paste territory.

My biggest mistake: The first time I made this, I over-processed the pistachios and ended up with pistachio butter. It actually made the cake incredibly moist (silver lining), but it wasn’t quite right. Now I set a timer and pulse in short bursts.

Step-by-Step: Making Your Pistachio and Raspberry Cake

Step 1: Prep Work (Don’t Skip This!)

Preheat your oven to 180°C (160°C fan)/350°F. I’ve learned the hard way that ovens vary wildly – mine runs hot, so I always use an oven thermometer. Best £6 I’ve spent on baking equipment.

Grease and line three 20cm (8-inch) round cake tins with baking parchment. I use a light spray oil on the sides and then line the bottom with parchment circles. This bit is tedious but essential – nobody wants cake stuck to the tin.

Step 2: Make Your Pistachio Sponge

In a large bowl or stand mixer, cream together your softened butter and sugar for 3-5 minutes until it’s pale, fluffy, and looks almost mousse-like. This is crucial for getting air into the batter, which means a lighter cake. I usually do this while dancing around the kitchen to whatever’s on Radio 2.

Add your eggs one at a time, beating well after each addition. If it looks a bit curdled, don’t panic – just add a tablespoon of your flour and it’ll come back together.

Mix in your vanilla extract.

In a separate bowl, sift together your plain flour, baking powder, bicarbonate of soda, and a pinch of salt. Then gently fold in your ground pistachios.

Add half the dry ingredients to your butter mixture and fold gently – you’re not beating it to death, just bringing it together. Add half the milk, fold again. Repeat with the remaining flour mixture and milk.

If you’re using food colouring, add just 1-2 drops now and fold through until evenly distributed.

Here’s where I messed up the first time: I over-mixed the batter after adding the flour. The result? Dense, heavy cake layers that my youngest described as “bouncy.” Not the look we’re going for. Mix just until you can’t see any streaks of flour, then stop. Trust the process.

Divide the batter evenly between your three prepared tins. I weigh them to be exact (each tin should have about 400g of batter), but you can also eyeball it if you’re feeling confident.

Bake for 25-30 minutes, until a skewer inserted in the centre comes out clean and the cakes spring back when gently pressed. Start checking at 25 minutes – don’t open the oven before that or they might sink.

Let them cool in the tins for 10 minutes, then turn out onto a wire rack to cool completely. Resist the urge to taste-test while they’re warm (I never resist this urge, but you should).

Step 3: Make the Pistachio Cream Filling

This is where the magic happens, and it’s honestly so much easier than making buttercream. Plus, it tastes absolutely dreamy – light, creamy, and perfectly pistachio-y without being too sweet.

In a large bowl (or your stand mixer bowl), combine your mascarpone and pistachio paste. Mix gently until smooth – you don’t want to overwork mascarpone or it can split.

In a separate bowl, whip your double cream with the icing sugar and vanilla until it holds soft peaks. Don’t over-whip or you’ll end up with butter (learned that one the hard way).

Gently fold the whipped cream into the mascarpone mixture in three additions. Be gentle here – you want to keep all that lovely airiness.

Add a tiny pinch of salt, fold once more, and taste it. Adjust if needed – maybe more pistachio paste if you want a stronger flavour.

Pop it in the fridge while you wait for your cakes to cool completely. This firms it up nicely and makes assembly much easier.

Step 4: Assembly Time (The Fun Bit!)

Right, your cakes are completely cool (patience is a virtue, even though I’m terrible at it), and your pistachio cream is chilled and ready to go.

Place your first cake layer on your serving plate or cake stand. I use a flat plate because I quite like the rustic, unfussy look of this cake.

Spread about a third of your pistachio cream over the first layer – don’t be shy, you want a generous amount. I usually do about 1-1.5cm thick.

Scatter about 200g of fresh raspberries over the pistachio cream. I gently press them in slightly so they don’t all roll off when you add the next layer (speaking from experience here).

Top with the second cake layer and repeat – another third of the cream, more raspberries pressed in gently.

Add your final cake layer on top.

Spread the remaining pistachio cream on top of the cake. You can make it smooth and elegant, or do what I do and create lovely swoops and swirls with the back of a spoon. Very “artisanal bakery” if anyone asks.

Here’s a tip I learned: If you want really clean, sharp layers, pop the assembled cake (without the final decoration) in the fridge for 30 minutes. This firms everything up and makes it slice beautifully.

Step 5: Make It Beautiful

Now for the best part – making it look absolutely stunning with minimal effort.

Pile your remaining fresh raspberries on top of the pistachio cream. I like to create a generous mound in the centre – it looks abundant and celebratory.

If you’re feeling fancy, scatter some chopped pistachios over the raspberries. The contrast of textures is lovely.

A few sprigs of fresh mint tucked in among the berries adds a gorgeous pop of colour.

Just before serving, dust the whole thing with a light snow of icing sugar through a fine sieve. This is totally optional but makes it look incredibly elegant.

Stand back. Take 47 photos for Instagram. Marvel at how professional it looks. Try not to eat it all before your guests arrive.

Common Questions About Pistachio and Raspberry Cake (Things People Actually Ask Me)

Can I make this cake in advance?

Absolutely! I actually think this cake tastes better a few hours after it’s made. The pistachio cream sets slightly and the raspberries release a bit of their juice, which soaks into the cake ever so slightly. You can:

• Bake the cake layers up to 2 days ahead, wrap them tightly in cling film, and store at room temperature
• Make the pistachio cream up to 24 hours ahead and keep it in the fridge (give it a gentle stir before using)
• Assemble the whole cake up to 6 hours before serving and keep it in the fridge (but bring to room temperature 30 minutes before serving for best flavour)

My pistachios are roasted and salted – can I still use them?

Yes! I’ve done this loads of times. Just reduce the salt in the cake recipe by half, and rinse off any excess salt from the pistachios before grinding. The roasted flavour actually adds a lovely depth, though the colour won’t be quite as bright green.

Can I use frozen raspberries?

For the decoration on top, I’d really recommend using fresh raspberries – they just look so much prettier. But for the layers inside? Frozen work perfectly fine. Just thaw them completely and drain off any excess liquid before using.

My pistachio cream is too runny – help!

This sometimes happens if your cream wasn’t whipped enough or if your mascarpone was too soft. Pop it in the fridge for 20-30 minutes and it should firm up nicely. If it’s still too soft, you can whip in another 2-3 tablespoons of icing sugar to help stabilize it.

How do I store leftover cake?

Keep it in an airtight container in the fridge for up to 3 days. The fresh raspberries will start to soften after day 2, but it still tastes gorgeous. Let it come to room temperature for about 20 minutes before serving for the best flavour and texture.

Can I freeze this cake?

The unfrosted cake layers freeze brilliantly for up to 3 months. Wrap each layer individually in cling film, then in foil. Thaw overnight in the fridge before filling and assembling. I don’t recommend freezing the assembled cake because the mascarpone cream can weep when it thaws, and the raspberries won’t be as nice.

What if I can’t find pistachio paste?

Make your own! Blend 100g pistachios with 2 tablespoons of neutral oil and a tablespoon of icing sugar until smooth. It takes about 2 minutes in a food processor. Or, you can use pistachio butter (the kind without added sugar) and add a bit more icing sugar to the cream to compensate.

Why is my cake dry?

Usually one of three things: over-mixing the batter, over-baking, or using too much flour. Make sure you’re measuring properly (weigh everything if you can), don’t mix more than necessary once you add the flour, and start checking for doneness at 25 minutes. The pistachio cream filling does help keep things moist though!

Can I make this dairy-free?

I’ve successfully made the cake layers with dairy-free butter (Naturli is my favourite) and oat milk. For the filling, you could try coconut cream whipped with dairy-free cream cheese, though I haven’t tested this myself so can’t guarantee the results.

The raspberries keep falling off when I slice it – any tips?

Yes! Gently press the raspberries into the pistachio cream when you’re layering, and chill the assembled cake for 30 minutes before slicing. Use a sharp, thin knife and wipe it clean between each slice. The cake will hold together much better when it’s been chilled.

Flavour Variations I’ve Tried (And Loved)

The Lemon Pistachio Version

Add the zest of 2 lemons to the cake batter and swap the raspberries for thin slices of lemon curd between the layers. Keep the pistachio cream the same. It’s like a sophisticated lemon meringue pie in cake form.

Strawberry Season Swap

Can’t get raspberries? Hulled and halved strawberries work beautifully. They’re a bit sweeter than raspberries, so I sometimes add a tiny squeeze of lemon juice to the cream to balance it out.

The Chocolate Lover’s Version

Mix 2 tablespoons of cocoa powder into the pistachio cream for a chocolate-pistachio version. Keep the raspberries – the combo is absolutely divine. My 13-year-old requested this for her birthday.

Cherry and Pistachio

If cherries are in season, use pitted fresh cherries instead of raspberries. You might want to macerate them with a tablespoon of sugar for 30 minutes first to draw out some juice.

Extra Decadent White Chocolate

Melt 100g white chocolate, let it cool slightly, and fold it into the pistachio cream before assembling. It makes the filling richer and more stable. Warning: wildly delicious.

Budget-Friendly Tips (Because Pistachios and Mascarpone Aren’t Cheap)

Look, I’ll level with you – pistachios can be expensive, and mascarpone isn’t exactly budget-friendly either. But I’ve found ways to make this cake without breaking the bank:

1. Buy pistachios in bulk: Whole Foods, Costco, or even online suppliers sell pistachios much cheaper than those fancy little packets in Waitrose. I usually pay about £12-15 per kilo in bulk vs £5 for 100g in packets.
2. Make your own pistachio paste: Shop-bought pistachio paste can cost £8-12 for a small jar. Making your own costs about £2 worth of pistachios plus a splash of oil.
3. Watch for mascarpone deals: I stock up when Tesco or Sainsbury’s have their Italian weeks and mascarpone goes on offer. It freezes beautifully for up to 3 months.
4. Use frozen raspberries for the filling: Save the pretty fresh ones for decoration on top. Frozen raspberries (thawed and drained) work perfectly in the layers and cost a fraction of fresh.
5. Make a 2-layer cake instead of 3: Still impressive, uses less ingredients, perfect for smaller gatherings. Divide the recipe by 1.5.
6. Skip the fancy decorations: You don’t need loads of chopped pistachios and mint sprigs on top – a pile of raspberries and a dusting of icing sugar looks just as gorgeous.
7. Substitute some of the mascarpone: You can use half mascarpone and half full-fat cream cheese for the filling. It’s slightly tangier but still delicious and saves about £3.

What People Have Said (Real Feedback from Real People)

My mum, who claimed she “wasn’t bothered about a birthday cake,” ended up having two slices and texted me later that evening: “That was so much nicer than I expected – not too sweet at all, and I loved the fresh berries. Can you make it again for Margaret’s birthday?”

My neighbour Sarah made this for her daughter’s baby shower and texted me: “Everyone raved about how light and elegant it was. Not one of those heavy, overly sweet cakes. I felt like a proper baker!”

When I brought this to my daughter’s school bake sale, it sold in literally 3 minutes. The teacher who bought it told me the next day it was “the most sophisticated cake she’d had in years” and that the pistachio cream was “dangerously good.”

My husband, who usually picks at cake, finished his slice and actually went back for seconds, declaring: “This is what cake should taste like – you can actually taste all the different flavours.”

Final Thoughts: Is This Cake Worth Making?

Here’s the thing – this pistachio and raspberry cake looks incredibly impressive. Every time I make it, people assume I’ve spent hours slaving away or that I’m some sort of baking wizard. But the reality? It’s actually simpler than most layer cakes because you’re not faffing about with heavy buttercream frosting all over the outside.

The cake layers come together like any normal sponge. The pistachio cream is literally just whipped cream folded into mascarpone and pistachio paste – easier than making buttercream, in my opinion. The assembly is just spreading and stacking. Nothing scary here.

But the result? A stunning, elegant, absolutely delicious cake that lets the flavours really shine. Without all that heavy frosting, you can actually taste the pistachio in the sponge and the cream, and the fresh raspberries add these gorgeous bursts of tartness. It’s sophisticated without being fussy, impressive without being difficult.

The kind of cake that makes people go quiet when they take their first bite (always a good sign). The kind that gets described as “refined” and “not too sweet” – which, let’s be honest, is what we all want in a proper celebration cake. The kind that looks absolutely stunning in photos but is actually quite forgiving to make.

Is it worth making? Absolutely. Would I make it again? I already have, multiple times. Will I keep making it? You bet your bottom dollar I will.
