A Lemon Traybake is a simple sponge cake infused with fresh lemon zest and juice, then baked in a tray rather than individual tins. Once cooled, it’s topped with lemon icing and sometimes sprinkled with lemon zest. Mary Berry’s version is straightforward and reliable, producing a moist, delicious cake every time.
225g self-raising flour
225g caster sugar
225g butter, softened
4 large eggs
2 tsp baking powder
Zest of 2 lemons
2 tbsp milk
250g icing sugar, sifted
Juice of 1 lemon
Zest of 1 lemon (for decoration)
Preheat oven to 180°C (160°C fan). Grease and line a rectangular baking tin with baking paper.
In a bowl, beat butter, sugar, eggs, flour, baking powder, lemon zest, and milk together until smooth.
Pour mixture into the prepared tin, spread evenly, and bake for 30–35 minutes until risen, golden, and springy. Cool in the tin.
Mix icing sugar with lemon juice until smooth and slightly runny.
Spread icing evenly over the cooled cake. Scatter lemon zest on top for decoration.
Once icing sets, cut into squares and serve.
