- 4 large eggs, at room temperature
- 225g self-raising flour

How to Make Mary Berry Old School Traybake
- Prepare the oven: Preheat the oven to 180°C or 160°C fan. Grease and line a 23 x 30cm traybake tin with baking parchment, making sure the paper comes up the sides.
- Mix the cake batter: Put the butter, caster sugar, eggs, self-raising flour, baking powder, milk and vanilla into a large bowl. Beat with an electric mixer until pale, smooth and well combined. The mixture should drop easily from a spoon.
- Fill the tin: Spoon the mixture into the prepared tin and gently level the surface with a spatula so it bakes evenly.
- Bake the traybake: Bake in the centre of the oven for 25 to 30 minutes, until lightly golden and springy to the touch. A skewer inserted into the centre should come out clean.
- Cool completely: Leave the cake to cool in the tin for 10 minutes, then lift it out using the parchment and leave on a wire rack until completely cold.
- Ice the cake: Mix the icing sugar with enough warm water to make a smooth, pourable icing. Spread over the cooled cake and finish with sprinkles or coconut if using. Leave to set before slicing.

Tips
Why is my traybake dry?
This usually means it has been baked for too long. Check the cake a few minutes before the end of the baking time and remove it as soon as it feels springy.
How do I get an even sponge?
Make sure the batter is evenly spread in the tin and the oven shelf is in the middle so the heat circulates properly.
Can I add flavourings?
A little lemon zest or almond extract works beautifully and still keeps the cake traditional.
Serving Suggestions
- Serve with a mug of tea for a classic afternoon treat
- Pack into lunchboxes once the icing has set
- Add custard and serve warm as a simple pudding
