About this recipe: There's enough mixture here to make a kids birthday cake or a huge cake. Trust me, baking cakes is NOT easy for me :)

Serves: 30 

  • 225g (8oz) self-raising flour
  • 2 teaspoons baking powder
  • 225g (8oz) caster sugar
  • 225g (8oz) margarine
  • 5 large free range eggs
  • few drops vanilla essence
  • 4 tablespoons cocoa powder

Prep:10min  ›  Cook:40min  ›  Ready in:50min 

  1. Preheat the oven to 170 C / Gas 3.
  2. The method is just as simple. Sieve the flour and baking powder together, add the sugar, margarine and eggs, and vanilla essence, whisk, mix or blend in a processor. Easy peasy.
  3. Continue, scraping down the sides occasionally, until you have a well-combined mixture that will drop off a spoon when tapped. If it seems a little stodgy, add a tiny drop of milk.
  4. Spoon half the mix into a separate container or bowl. In one of the bowls, fold in your cocoa until well mixed.
  5. Grease and lightly flour your roasting tray and start spooning the different mixes in one at a time and use a chopstick (or similar) to make swirly patterns in the mix as you go!
  6. Stick it in the oven until a skewer inserted near the centre comes out clean, about 35 minutes and voila!


This is great to use as a base for childrens' party cake. I'm using it to make a giant surfboard (am making 2 lots).

A really nice, easy cake. The chocolate cake part was a bit drier than the plain cake - a common problem - but I'd definitely make this again. - 05 Apr 2014


Lovely marble cake. First time I made a marble cake and I'm really pleased with it. Very easy to do and it made a lovely sponge. I only put in 2 spoons of cocoa after reading other reviews and I think that was enough. Will def make again - 19 Feb 2015


Turned out well. I added only 2 tbsp of cocoa powder as 4 seemed far too many, and this meant the cocoa sponge wasn't as dry as it might have been otherwise. Iced with chocolate buttercream, it was fab. - 05 Feb 2015
