Essential Ingredients for Your Sponge
Getting the basics right makes all the difference. Measure ingredients accurately and use the best produce you can find. This helps the traybake develop a fine crumb and bright flavour.
Selecting Quality Lemons
Always choose unwaxed lemons so the lemon zest is clean and full of oils. Finely grate zest from two fruit for the recipe and reserve a little juice to balance the sweetness.
Fresh citrus lifts the batter and makes the drizzle vivid. Good fruit keeps the aroma lively for days.
Choosing the Right Flour
Use 275g of self-raising flour to ensure a light, even rise in the sponge. Sifting the flour gives a softer texture and helps distribute the 25g of poppy seeds evenly.
Combine measured 225g of soft butter with 225g of caster sugar, four large eggs and 4 tbsp milk for a smooth batter. These ingredients create the classic lemon poppy seed sponge that pairs perfectly with a thin glaze.
Preparing Your Baking Tin and Oven
Start with temperature and tools in order. Preheat the oven to 180°C/160°C fan/Gas 4 before you mix the batter. This creates a steady heat that helps the sponge rise and set evenly.
Grease and line a 30cm x 23cm x 4cm traybake tin with good-quality baking parchment. A well-prepared tin makes removing the slice simple and keeps the edges neat.
“A properly greased and lined tin is a small step that gives professional results.”
Mary Berry always stresses the need to grease the tin so the edges do not overbake. Lining with parchment lets you lift the whole cake out once it has cooled.
- Ensure the oven is fully up to temperature before the tin goes in.
- Use fresh parchment that covers the base and sides for easy release.
- Avoid opening the oven door in the first 20 minutes of baking to keep heat stable.
Taking these simple cooking and baking precautions makes the process smoother. Your lemon cake will bake more evenly and look as good as it tastes.

Mixing the Perfect Batter
Good mixing makes all the difference. Start in a large bowl so you have room to work and air can be incorporated easily.
Achieving the Ideal Consistency
Cream the softened butter with caster sugar until pale and fluffy. Beat in the eggs, then fold in the self-raising flour for a smooth, even mixture.
Add the lemon zest and lemon juice now so the citrus flavour is spread through the whole batter. Use an electric whisk for 2 minutes to trap air and produce a light sponge.
Gently fold in the poppy seeds to prevent clumping and keep distribution even. Stir in 4 tbsp milk if the batter feels too stiff; this helps it spread into every corner of the prepared tin.
Pour the mixture into your lined tin and use a spatula to level top so the bake rises uniformly. Remember the glaze mix of icing sugar and lemon juice for later; keeping that in mind prevents the batter drying out.

Baking to Golden Perfection
Aim for an even, warm bake so the top colours up and the edges start to pull away from the tin.
Place your tin in the preheated oven and bake for 35–40 minutes until the cake is golden and feels firm to the touch.
The traybake will begin to shrink slightly from the sides of the tin when it is near done. Gently press the centre with a fingertip; it should spring back. This is the best sign that the sponge is cooked through.
- Ensure the mixture has a level top before it goes in to help an even rise.
- Keep an eye during the final minutes — cooking times can vary by oven.
- After baking, leave cool in the tin so the structure sets before you remove the parchment and cut slices.
When cool, remove the paper and prepare the drizzle for a classic finish. A careful bake here gives a moist, tender result rather than a dry sponge.
Adding the Signature Lemon Glaze
Prepare a pourable icing by whisking the sugar with juice until smooth. While the cake still warm, sift 150g of icing sugar into a bowl and add 1–2 tbsp of lemon juice a little at a time.
Aim for a glossy, pourable glaze: stop when it falls in a steady ribbon. Apply quickly so the drizzle soaks into the sponge and brightens every slice.

“Applying the glaze while warm helps the liquid penetrate the sponge and keeps it moist for days.”
Use a spoon or a pastry brush to spread the mixture across the top, ensuring even coverage. Work from one side to the other so each square gets a citrus hit.
- Mix lemon juice gradually into icing sugar to control thickness.
- Spread the glaze while the cake still warm for better absorption.
- Once glazed, leave cool completely so the sugar sets to a light, crisp finish.
| Step | Action | Result |
|---|---|---|
| Mix | Sift icing sugar, add juice slowly | Glossy, pourable glaze |
| Apply | Spoon or brush over top while warm | Glaze soaks into sponge |
| Set | Leave cool completely | Crisp, sweet surface and lasting moisture |

Expert Tips for Success
A handful of practical tips will help you nail the texture and flavour every time.
Avoiding a Dry Sponge
Do not overbake. Start checking after 35 minutes in the oven and use a skewer in the centre to test doneness.
If the top browns too fast, cover loosely with foil for the final minutes. Use a good-quality baking spread or softened butter to keep the crumb rich and moist.
Ensuring Even Poppy Seed Distribution
Mix the poppy seeds with the flour in a separate bowl before folding into the wet mix. This stops clumps and gives balanced pockets of seed through the sponge.
Checking for Doneness
Press the centre gently — it should spring back — but a skewer is most accurate. If it comes out clean, the bake is ready. If not, return for a few more minutes and recheck.
- Measure lemon juice and lemon zest accurately for bright flavour.
- If the batter looks stiff, add 1 tbsp milk to aid an even rise.
- Apply the glaze while the cake still warm so the icing sugar soak-in keeps the sponge moist.
“Apply the glaze while the cake still warm for best absorption.”
Creative Variations to Try
Small changes to the mix can turn the classic traybake into a seasonal showstopper.
Swap the lemon zest for orange zest to soften the sharp citrus note and give the bake a sweeter aroma. For a nuttier crumb, fold a handful of ground almonds into the flour; this creates a rounded texture that pairs well with tea.
For extra indulgence: sandwich a thin layer of lemon curd between two slim slices of sponge before you apply the lemon drizzle. This adds a tart, glossy centre that cuts through the richness of the butter.
To lighten the recipe, reduce the sugar slightly and replace some butter with plain Greek yoghurt. You can also try different poppy varieties — blue or white — to alter the loaf’s look without changing the flavour.
Make mini versions for single portions or freeze small squares for later. For a summer twist, add a splash of elderflower cordial to the drizzle for a floral lift.
“These variations keep the reliable moist sponge while letting you personalise each bake.”
- Swap citrus zest for orange for a milder profile.
- Add ground almonds for a nutty finish.
- Try lemon curd between slices for added tang.
- Reduce sugar and swap some butter for yoghurt to cut calories.
