Mary Berry Victoria Sponge Traybake is a sheet-cake version of the traditional Victoria sponge. The fluffy vanilla sponge is baked in a rectangular tin and typically layered with raspberry jam and a light dusting of icing sugar, making it easy to slice and share.
225g self-raising flour
225g caster sugar
225g softened butter
4 large eggs
2 tsp baking powder
2 tsp vanilla extract
2 tbsp milk
200g raspberry jam
Icing sugar (for dusting)
Optional: whipped cream or buttercream
Line your traybake tin with parchment paper and lightly grease the sides so the sponge lifts out easily after baking.
Set your oven to 160°C (fan) or 180°C (conventional) to ensure even baking.
Add flour, caster sugar, butter, eggs, baking powder, vanilla, and milk into a mixing bowl. Beat until the batter becomes smooth, pale, and creamy.
Spread the mixture evenly into the prepared tin and smooth the surface using a spatula.
Bake for 25–30 minutes or until golden and a skewer inserted into the centre comes out clean.
Allow the sponge to cool in the tin for 10 minutes, then transfer to a wire rack until fully cooled.
Once cooled, spread a generous, even layer of raspberry jam over the sponge.
Dust the top with icing sugar and slice into squares for serving.
