  • 1 tsp vanilla extract
  • 2 tbsp cocoa powder


  1. Heat oven to 180C/fan 160C/gas 4. Grease a 20cm cake tin and line the bottom with a circle of greaseproof paper.

  2. If you want to make life easy, simply put 225g butter, 225g caster sugar, 4 eggs, 225g self-raising flour, 3 tbsp milk and 1 tsp vanilla extract into a food processor and whizz for 1-2 mins until smooth.

  3. If you prefer to mix by hand, beat 225g butter and 225g caster sugar together, then add 4 eggs, one at a time, mixing well after each addition.

  4. Fold through 225g self-raising flour, 3 tbsp milk and 1 tsp vanilla extract until the mixture is smooth.

  5. Divide the mixture between 2 bowls. Stir 2 tbsp cocoa powder into the mixture in one of the bowls. Take 2 spoons and use them to dollop the chocolate and vanilla cake mixes into the tin alternately.

  6. When all the mixture has been used up (and if young kids are doing this, you’ll need to ensure the base of the tin is fairly evenly covered), tap the bottom on your work surface to ensure that there aren’t any air bubbles.

  7. Take a skewer and swirl it around the mixture in the tin a few times to create a marbled effect.

  8. Bake the cake for 45-55 mins until a skewer inserted into the centre comes out clean. Turn out onto a cooling rack and leave to cool. Will keep for 3 days in an airtight container or freeze for up to 3 months.

I found this cake very dense but the taste was ok.

This was a really good cake - light and moist. It took about 10-15 minutes more to cook than the recipe stated.

Changed the recipe by splitting the batter into three rather than two, and adding frozen raspberries into the third bit. I then used the “zebra cake technique”, to layer the chocolate, raspberry and plain layers, so that it had a really cool pattern when it was cut into. I would say the chocolate layer was a bit dry, so I’d consider trying the boiling water trick with the cocoa others have mentioned or just trying a different recipe if I was to make a marble cake again.

Looked amazing pretty easy to make but I wouldn't use 4 eggs next time, tasted very eggy, like pancakes but other than that will use recipe again.

This cake didn't last 4 days, but went in one day. My husband, 2 boys and I loved it. Its not very moist or very dry or very sweet, for us it was just right (we aren't chocolate cake fans). I threw it all in with the electric hand whisk and like someone recommended I added some hot water to the coco powder before adding it to the mixture. I have a gas oven so always bake longer than the recipes ask, so mine was done in about an hour and 10mins at gas mark 4/5.

My husband and son thought this was store-bought. It was super easy to make and unbelievably delicious! Definitely a keeper.

This is a brilliant recipe. I was an absolute beginner in cooking and baking and decided to start with this in January of this year. I've made it around 4 times now and each time its absolute perfection and looks really smart like you've made much more of an effort! Highly recommend.

A lovely recipe, tastes absolutely wonderful but for such a large cake and single tier, I had to bake it for 1 hour and 5 minutes before it was baked through - it was still slightly dense and could've done with a tad longer for a nice fluffy effect. However, my gas oven is also trash so well. :) Nicely complimented with a thin layer of vanilla buttercream (100g butter to 200g icing sugar). Wonderful!

Great cake! I make it in loaf, round and cup cakes, turns out great every time. Nice and fluffy. I prefer to hold back on two tablespoons of sugar.

I followed the exact instructions. However ended up with slightly too much do I make cupcakes with it and should the temperature and time change for my oven? Many thanks.

Thanks for your questions. This will be the right amount of mixture for a standard 20cm round tin. A shallow tin or different tin size could be what led to leftovers, in which case cupcakes are a good solution. The oven temperature would stay the same. Cook for 15 - 20 mins. If you're cooking a cake at the same time as cupcakes, you need to make sure you whip the cupcakes out super fast so that you don't let the heat out of the oven and cause the cake to collapse.

It is the first time I ever wanted to cook a cake, It was delicious but the cake was so thick and I don't know why? Any tips?

Hi there, thanks for your question, you can find good cup to gram convertors online. This recipe was tested in metric so we don’t have the conversions.

Think i only have a 7in cake tin, so was wondering if I could use a 2 lb loaf tin instead and how should I adjust the cooking time?

Hi everyone. Can you please tell me what size cake this mix will make? I'm after a 9 inch and 6 inch round that will be 3-4 inches high so would a double mix do? Thanks

I want to bake 2 cakes and layer it with something in between. Does anyone have any recommendations that will compliment this cake? I've tried Choc Ganache, but my family didn't like it too much. I'm looking for something cream based - i think?

I would try Cream cheese icing from the Humming bird bakery. It is delish!

How about a chocolate cream: whip together 300ml of double cream with 1 tsp of vanilla paste until just holding its shape. Melt 125g chocolate, allow to cool a little then fold into the double cream. You can leave it marbled or fold together entirely.

Excellent, reliable recipe! Have made it three times now and always comes out great. I added a little brewed coffee to the chocolate part and it worked a treat!
