Mary Berry Lemon Drizzle Tray Bake: The Classic Recipe

If there’s one recipe that has followed me through literally every stage of my baking life, it’s this one. I’m talking school cake sales, birthday teas, “I need to bring something to the village fete in three hours” panic bakes, Sunday afternoons with the kids. Mary Berry’s lemon drizzle tray bake has done it all.

I’ve made it so many times I could probably do it half-asleep. And honestly? I’ve also got it wrong more times than I’d like to admit. Cold butter, drizzle poured on too late, oven running too hot. I’ve done all of it so you don’t have to.

This post is for people who want the classic recipe and the real-world knowledge that makes the difference between a so-so bake and the version that disappears within ten minutes of hitting the table. I’m not going to just list ingredients and move on. I’m going to walk you through the whole thing properly.

If you’re after a quick five-line recipe with no context or tips, there are plenty of those already. But if you want to understand why the recipe works the way it does and what to watch out for, you’re in the right place.

Key Takeaways

• This is an all-in-one bake, which means everything goes in one bowl: no creaming, no faff.
• The drizzle goes on while the cake is still warm. Not hot, not cold. Warm. This is the step most people get wrong.
• Butter or baking spread both work, but your butter must be genuinely soft: not fridge-cold and not melted.
• The crunchy granulated sugar topping is Mary’s original. You can do an icing sugar glaze instead, but the texture is completely different.
• This tray bake cuts into 16–30 pieces depending on how generous you’re feeling, making it ideal for sharing.

What Makes Mary Berry’s Lemon Drizzle Tray Bake So Special?

There are approximately a million lemon drizzle recipes on the internet. So why does Mary Berry’s version keep coming up as the gold standard?

A few reasons. First, the all-in-one method, where everything goes into one bowl and gets beaten together, is genuinely foolproof. There’s no separate creaming of butter and sugar, no adding eggs one at a time while holding your breath hoping it doesn’t curdle. You just weigh everything out, dump it in, and mix. Even my eight-year-old can manage it.

Second, the tray bake format is just smart. You get more surface area, which means more of that gorgeous crunchy drizzle topping per slice. It also cuts neatly into squares or rectangles, which makes it infinitely easier to transport than a round cake. For school fetes, bake sales, or just feeding a house full of hungry kids, tray bakes are the format.

And third, the bit I think is most underrated: the ratio of sponge to drizzle is absolutely right. The sponge is light and lemony but not sharp. The topping brings the tang. Together they’re perfectly balanced.

The Ingredients (And What Actually Matters)

Here’s what you need for the classic Mary Berry lemon drizzle tray bake. I’ve also noted where you have a bit of flexibility and where you genuinely shouldn’t cut corners.

For the sponge:

• 225g softened butter (or baking spread; more on this below)
• 225g caster sugar
• 275g self-raising flour
• 2 tsp baking powder
• 4 large eggs
• 4 tbsp milk
• Finely grated zest of 2 lemons
• 1 tbsp fresh lemon verbena leaves, chopped (optional; see below)

For the drizzle topping:

• 175g granulated sugar
• Juice of 2 lemons (roughly 6–8 tbsp)

You’ll need a tray bake tin measuring approximately 30 x 23 x 4cm. I’d really recommend lining it properly with baking parchment rather than just greasing, as it makes lifting the baked traybake out so much easier, and the drizzle won’t stick to the tin.

Butter vs. Baking Spread

The original recipe calls for butter, but Mary Berry herself has used baking spread (like Stork) in various versions over the years. In my experience, both work well. Butter gives a richer flavour; baking spread tends to give a slightly lighter, airier sponge. The key is that whatever you use needs to be genuinely soft before you start.

I mean properly soft. Not “left out for twenty minutes on a cold December morning” soft. It should be yielding, almost greasy to the touch, spreadable without effort. If you press your finger into a block and it barely dents, it’s not ready.

Cold butter in an all-in-one bake causes lumpy batter, which means uneven rising. This was my most common mistake early on. Leave your butter out for at least an hour at room temperature, or if you’ve forgotten (as I frequently do), cut it into small cubes and microwave for about 10 seconds at a time, checking as you go. You want soft, not melted.

What Is Lemon Verbena and Do You Actually Need It?

Lemon verbena is a herb with an incredibly fragrant, almost floral lemon scent. Mary Berry’s original recipe includes a tablespoon of finely chopped fresh leaves. If you grow it in your garden or can find it at a good supermarket or garden centre, it does add a lovely aromatic depth to the sponge.

But honestly? I’ve made this recipe both ways dozens of times and it’s brilliant without it. If you can’t find lemon verbena, don’t stress. Extra lemon zest (add the zest of a third lemon to the batter) gives you a similar intensity. I’ve done this every time for the past two years and no one has ever complained.

On the Lemons Themselves

Please, please use fresh lemons. Bottled lemon juice doesn’t have the same fragrance and the flavour of the drizzle will be noticeably flatter. You need about two lemons’ worth of juice for the drizzle topping, which is roughly 6–8 tablespoons depending on the size and juiciness of your lemons. Roll them firmly on the counter before you cut and juice them; it really does help you get more juice out.

How to Make Mary Berry’s Lemon Drizzle Tray Bake

Preheat your oven to 180°C / 160°C fan / Gas 4.

Line your tray bake tin with baking parchment. I cut one large piece and press it into the corners of the tin, then trim or fold the overhang so it sits neatly. Greasing the tin before you add the paper helps it stick.

Make the batter:

Put all of the sponge ingredients into a large mixing bowl: butter, caster sugar, self-raising flour, baking powder, eggs, milk, lemon zest, and lemon verbena if using. Beat everything together using an electric hand mixer (or a stand mixer) for about 1–2 minutes until the batter is smooth and pale. If you’re doing it by hand with a wooden spoon, you’ll need to work a bit harder and go for a good 3–4 minutes.

The batter will be fairly thick, and that’s completely normal. Don’t worry that it looks too stiff to spread.

Into the tin:

Spoon and scrape the batter into your lined tin and smooth it out into an even layer with a spatula. Make sure you’re pushing it right into the corners.

Bake:

Place in the middle of your oven and bake for 35–40 minutes. The traybake is ready when:

• The top is golden and firm to the touch
• It springs back when you press the centre gently
• The edges are just beginning to pull away from the sides of the tin
• A skewer or cocktail stick inserted into the centre comes out clean

Do not open the oven during the first 25 minutes. This is one of those rules that genuinely matters for a sponge. Opening the oven too soon lets heat escape and can cause the middle to sink.

Make the drizzle:

While the traybake is in its final few minutes of baking, mix the granulated sugar and lemon juice together in a small bowl or jug. You want it runny enough to pour easily. If your lemons weren’t very juicy and the mixture looks more like wet sand, squeeze in a little extra juice.

Add the drizzle:

Here’s the critical bit. When the traybake comes out of the oven, leave it to cool in the tin for about five minutes. You want it warm, not hot. Then spoon or pour the lemon sugar mixture evenly over the surface.

The granulated sugar won’t dissolve completely, and that’s the whole point. You get a slightly crunchy, crystalised topping that contrasts beautifully with the soft sponge underneath. Don’t stir it around; just let it settle.

Leave the traybake to cool completely in the tin before attempting to cut it. I know it’s tempting. Resist.

Cut and serve:

Once completely cold, lift the whole traybake out using the edges of the parchment paper, and cut into squares or rectangles. Mary Berry suggests cutting into 30 small squares, which is ideal for a bake sale. For a family tea, I usually go for about 16–20 more generous pieces.

The Crunchy Topping vs. The Icing Sugar Glaze: Which Is Better?

This comes up a lot, so let’s settle it. Mary Berry’s original recipe uses granulated sugar mixed with lemon juice. This creates a crunchy, crystallised topping that adds texture to each slice.

Some people (including some versions of this recipe you’ll find online) use icing sugar mixed with lemon juice to create a smooth, sweet glaze instead. This soaks into the sponge and sets into a thin, glossy layer.

Here’s my honest take having done both:

My personal preference is the original crunchy topping, always. The texture is part of what makes this bake distinctly this bake, not just a lemon sponge. But if you’re serving it to people who prefer things on the sweeter, less tangy side (young children, for instance), the icing glaze is a nicer choice.

What To Do If Things Go Wrong

Right, let’s talk about the baking disasters I’ve experienced personally, because this is where most recipe posts let you down.

The middle has sunk

Usually caused by one of three things: oven opened too early, oven running cool so the batter never fully set before collapsing, or batter undermixed. The sponge should still taste good, so just slice around the sunken middle and no one will know. Next time, check your oven temperature with a thermometer; many home ovens run noticeably hotter or cooler than the dial suggests.

The drizzle has pooled at the sides and barely covered the middle

This happens when the traybake wasn’t level in the tin, or when the topping was poured all in one go. Pour slowly in a zigzag pattern across the whole surface, then use a spoon to guide it into the corners.

The drizzle soaked in completely and there’s no crunch

The cake was too hot when you added the drizzle, so the sugar dissolved. Leave it that five-minute window next time. If this happens, a dusting of icing sugar once it’s fully cool at least makes it look pretty.

The cake stuck to the tin

Always, always line with parchment. Greasing alone isn’t enough with this recipe because the sticky sugar drizzle makes it a nightmare to get out cleanly.

It tastes bland and not very lemony

Use the zest of three lemons in the batter rather than two, and make sure you’re using fresh lemon juice in the drizzle, not bottled. The zest is where all the flavour lives, while the juice is quite sharp but not particularly fragrant on its own.

Making It With Kids

This is genuinely one of the best recipes for baking with children because the all-in-one method is so straightforward. My eight-year-old can weigh out the ingredients, tip them into the bowl, and mix with an electric whisk (supervised, obviously) without too much drama.

The things to watch out for when baking with smaller children: don’t let them add the drizzle themselves while the cake is still very hot, and make sure any lemon juicing and zesting is done before they get involved, as zesters are sharp. The measuring and mixing are great for little ones though.

My teenagers, on the other hand, can now make this completely independently, which frankly is one of the most useful life skills I could have passed on.

Storing, Freezing and Making Ahead

Storing: Keep in an airtight tin or container at room temperature for up to three days. The crunchy topping softens slightly over time but the flavour actually improves on day two, as the lemon really develops.

Freezing: This bake freezes brilliantly. Let it cool completely, then either wrap the whole thing tightly in cling film and then foil, or cut into portions and freeze individually (great for packed lunches). Defrost at room temperature for a couple of hours. I’d recommend freezing before adding the drizzle if possible, then adding it fresh once defrosted, though it still works fine either way.

Making ahead: You can make this the day before you need it, which I’d actually recommend if you’re taking it to an event. The texture on day two is often even better than fresh. Just store airtight once the drizzle has fully set.

Variations Worth Trying

Once you’ve mastered the classic, this recipe is a lovely base to play with:

Extra zesty: Add the zest of three lemons to the batter and a little extra juice to the drizzle. Sharper and more aromatic.

Lemon and poppy seed: Add two tablespoons of poppy seeds to the batter. The slight nuttiness is a lovely contrast to the lemon.

Lemon and elderflower: Replace two tablespoons of the milk with elderflower cordial. Subtle but lovely, and particularly nice in summer.

Dairy-free: I’ve tested this with a plant-based spread (Flora Plant) and oat milk in place of the dairy versions. It works surprisingly well and the texture is just fractionally lighter.

Frequently Asked Questions

Can I make Mary Berry’s lemon drizzle tray bake without an electric mixer?

Yes, absolutely. You’ll need a large bowl, a wooden spoon, and a bit of elbow grease. The key is that your butter is genuinely soft before you start, which makes mixing by hand much more manageable. Beat vigorously for a good three to four minutes until the batter is smooth and there are no visible lumps of butter.

What size tin do I need for this recipe?

The standard size for Mary Berry’s recipe is 30 x 23 x 4cm (approximately 12 x 9 x 1.5 inches). If you only have a smaller tin, reduce the quantities slightly or expect the bake to take a little longer as the batter will be deeper. A tin that’s too small risks an undercooked middle.

Why is my lemon drizzle traybake dry?

The most common cause is overbaking. Check it at 35 minutes rather than waiting the full 40, and pull it out as soon as a skewer comes out clean. Also ensure your butter was properly soft, as undermixed batter doesn’t incorporate air well, which can result in a denser, drier texture.

Can I use plain flour instead of self-raising?

You can, but you’ll need to add extra baking powder: roughly 1 teaspoon per 100g of plain flour. Self-raising flour already has baking powder incorporated into it, so using plain flour without compensating will give you a very flat, dense result.

How long does lemon drizzle tray bake keep?

Stored in an airtight container at room temperature, it keeps well for up to three days. After that, it starts to dry out. You can freeze it for up to a month: just wrap individual slices in cling film for easy grab-and-go portions.

Can I double the recipe?

Yes, though you’ll need either a very large tin or two separate tins. The baking time may need to increase slightly, so check carefully with a skewer from 40 minutes onwards.

A Few Things Worth Knowing Before You Start

This isn’t a difficult bake, but a couple of things genuinely make the difference between average and brilliant. Soft butter, truly genuinely properly soft, is the most important thing. The warm-not-hot timing on the drizzle is the second. Get those two things right and you’re most of the way there.

And if it goes wrong first time? Make it again. Mary Berry herself talks about how baking is practice, not perfection. This recipe has survived my learning curve and it’ll survive yours.
