This lemon drizzle party traybake is the kind of cake that makes people smile. It’s soft, sunny, and unapologetically lemony, with a crisp sugar crust on top that melts into the sponge. You can slice it into neat squares for a birthday, picnic, or office treat, and it never feels fussy.

It’s straightforward to make, bakes evenly in one pan, and stays moist for days. If you love simple bakes that taste like sunshine, this one’s a keeper.

Why This Recipe Works

This traybake uses the classic creaming method, which traps air in the batter and gives a light, tender crumb. A mix of lemon zest and juice layers the flavor: zest in the sponge for fragrance, juice in the drizzle for a bright finish.

Using a lined rectangular tin helps the cake bake level and release cleanly. Finally, the drizzle is poured on while the cake is still warm, so it soaks in and forms that signature crackly top.

Ingredients

• For the sponge:
• 225 g unsalted butter, softened
• 225 g caster sugar
• 4 large eggs, room temperature
• 225 g self-raising flour
• 1/2 tsp fine salt
• 2 lemons, zest only (save the juice for the drizzle)
• 2 tbsp milk (optional, if batter is thick)

• For the drizzle:
• 100 g granulated sugar
• Juice of 2 lemons (about 80–100 ml)

• Optional decoration:
• Thin lemon zest strips or curls
• Icing sugar for dusting

Instructions

1. Prep the tin and oven. Heat the oven to 180°C (160°C fan) or 350°F. Line a 23 x 33 cm (9 x 13 inch) traybake tin with baking paper, leaving some overhang for easy lifting.
2. Cream butter and sugar. In a large bowl, beat the softened butter and caster sugar with an electric mixer for 3–4 minutes until very pale and fluffy.

   This step builds structure and lightness.

3. Add eggs gradually. Beat in the eggs one at a time, mixing well after each. If the mixture looks like it’s curdling, add a spoonful of the flour to bring it back together.
4. Fold in dry ingredients and zest. Sift in the self-raising flour and salt. Add the lemon zest.

   Fold gently with a spatula until just combined. If the batter seems very thick, fold in up to 2 tablespoons of milk to loosen it slightly.

5. Spread and level. Spoon the batter into the prepared tin. Smooth the top with a spatula so it bakes evenly.
6. Bake. Bake for 22–28 minutes, or until the top is golden and springy and a skewer inserted into the center comes out clean.

   Start checking at 22 minutes to avoid overbaking.

7. Mix the drizzle. While the cake bakes, stir together the granulated sugar and lemon juice in a small bowl. Don’t let the sugar fully dissolve—those crystals help create a lovely crunch.
8. Poke and pour. As soon as the cake comes out of the oven, poke holes all over with a skewer or toothpick. Pour the lemon drizzle evenly across the surface, letting it seep in.
9. Cool and set. Leave the cake to cool completely in the tin so the drizzle sets into a crackly top.

   Lift out using the paper and transfer to a board.

10. Slice to serve. Cut into 20–24 squares for party portions. Add zest curls or a dusting of icing sugar if you like.

Keeping It Fresh

Once cooled, store the traybake in an airtight container at room temperature for up to 4 days. The drizzle keeps the sponge moist, so it actually tastes better on day two.

For longer storage, wrap individual squares tightly and freeze for up to 2 months. Thaw at room temperature, uncovered, so the top stays slightly crisp.

Health Benefits

While this is a treat, it still has a few bright spots. Lemon provides vitamin C and natural antioxidants.

The cake uses butter, which brings fat-soluble vitamins and satisfying richness, helping smaller portions feel more indulgent. You can also reduce the sugar by 10–15% without losing structure, and the flavor will still shine thanks to the lemon. If you need to, use a gluten-free self-raising flour blend and the cake will still bake up soft and light.

Common Mistakes to Avoid

• Overmixing the batter: Once the flour goes in, fold gently.

  Too much mixing toughens the crumb.

• Cold ingredients: Butter and eggs should be at room temperature so the batter emulsifies and rises evenly.
• Skipping the poke: The drizzle won’t penetrate if you don’t make enough holes. Go all over, especially the corners.
• Overbaking: Dry cake won’t soak up the drizzle the same way. Check early and pull it as soon as a skewer comes out clean.
• Using icing sugar in the drizzle: Stick to granulated sugar for that classic crunchy top.

Variations You Can Try

• Lemon-Lime Traybake: Swap half the lemon juice for lime and add lime zest with the lemon zest.

  It’s brighter and slightly more floral.

• Poppy Seed Twist: Fold 2 tablespoons of poppy seeds into the batter for a gentle crunch and a bakery-style look.
• Blueberry Burst: Scatter 150 g fresh blueberries over the batter before baking. Toss them in a teaspoon of flour first to help prevent sinking.
• Glazed Finish: Instead of a crunchy drizzle, mix 150 g icing sugar with 2–3 tablespoons lemon juice to a pourable icing. Spread on once the cake is cool for a smooth, glossy top.
• Dairy-Free Version: Use a good-quality dairy-free baking spread and a plant milk.

  The texture remains soft and moist.

FAQ

Can I make this the day before serving?

Yes. In fact, it’s often better the next day because the drizzle settles and the flavor deepens. Keep it in an airtight container at room temperature.

What if I don’t have self-raising flour?

Use 225 g plain (all-purpose) flour plus 2 teaspoons baking powder and 1/4 teaspoon fine salt.

Sift well before folding in.

Can I use bottled lemon juice?

Fresh lemon juice tastes brighter and cleaner, and you need the zest for fragrance. If bottled is your only option, use it for the drizzle, but still add fresh zest to the batter.

How do I stop the top from getting soggy?

Let the cake cool in the tin until the drizzle sets, then store it uncovered for 30 minutes before sealing it in a container. Avoid stacking slices while still warm.

What size tin should I use if I don’t have a 9 x 13?

An 8 x 12 inch tin also works, but add a few minutes to the bake time.

For two 20 cm (8 inch) square tins, divide the batter and start checking at 18–20 minutes.

Can I add a cream topping?

Yes, a light lemon cream cheese frosting is lovely. Just note it changes storage: keep the frosted cake in the fridge and bring slices to room temp before serving.

How do I know the cake is done?

The top should be golden and spring back when gently pressed. A skewer inserted into the center should come out clean or with a few moist crumbs, not wet batter.

Is it suitable for freezing?

Absolutely.

Freeze uncut or in individual squares, tightly wrapped. Thaw at room temperature, then refresh with a little extra lemon zest on top if you like.
