Finally, I have wrestled half of Mark’s sponge cake recipe from him! Well. I have the ingredient list. It involves:

200g caster sugar

200g softened butter

4 beaten eggs

200g self-raising flour

1 tsp baking powder

2 tbsp milk

Filling as preferred. Mark likes cream with various berries. And to chuck in some cocoa powder and chocolate chips.

If I was to guess, I’d suggest creaming butter and sugar, mixing in the eggs one by one, and then stirring in the flour and baking powder, tipping in the milk at the same time. Any cocoa powder goes in with the flour.

But that’s just me.

Oh, and baking at about 180C for about half an hour.
