  • 85g unsalted butter, softened
  • 175g icing sugar, sieved


  1. Heat oven to 190C/170C fan/gas 5. Butter and line two 20cm sandwich tins with baking parchment.

  2. Use a handheld electric whisk or a freestanding mixer to beat 175g softened unsalted butter and 175g golden caster sugar together in a bowl until creamy and light in colour. Then add 1 large egg, still mixing.

  3. Sieve 50g cocoa powder, 100g self-raising flour and a pinch of salt into another bowl and add a third of that to your wet ingredients.

  4. Once combined, add 1 more large egg and another third of the flour mixture and work that in.

  5. Then add 1 more large egg and the remaining flour and beat until you have a smooth thick batter. If the batter is stiff, stir in a splash of milk to loosen it.

  6. Divide the mixture between the tins and smooth the top with the back of a spoon.

  7. Bake for 20-25 mins until springy to the touch. Take out of the oven and leave in the tins for 10 mins before turning out onto a wire rack to cool completely.

  8. Meanwhile, make the buttercream by melting 50g dark or milk chocolate in the microwave, or in a bowl over just simmering water, making sure the base doesn’t touch the water. Leave to cool. 

  9. Beat 85g softened unsalted butter and half of the 175g sieved icing sugar together until light and fluffy. Add the remaining icing sugar and melted chocolate and mix together. If the icing is runny, chill in the fridge until it is firm but still spreadable.

  10. To assemble the cake, put a small dollop of icing onto a plate and put one of the cakes on top. Spread the top of the cake with half the icing, leaving a 1cm border around the edge.

  11. Put the second cake on top and push down very gently. Spread the remaining icing over the top.

I added an extra 25g flour (to make it up to 175g with the cocoa) and 1+1/2 teaspoons of baking powder. It rose perfectly. I hope this helps.

Have made this cake several times, it doesn't rise at all. Tastes delicious but doesn't get very high. Will try doubling the mixture next time.

I double the mix, makes a normal size cake then!

Made this recipe today, and made it exactly how the recipe said. I didnt use x2 tins, instead used on big tin and it cooked in 25mins at 185deg. It had such a lovely rise, about 2/3rds bigger than the batter. I did also add a few chopped up chocolate pieces to the mixture to make chocolate chip cake.

Poor recipe. Cake hardly rose at all and felt the mixture was much too thick. Also the buttercream was in no way "creamy" despite following the recipe exactly. I had to add extra chocolate and some full fat milk so that I could actually paste it onto the cake. Won't be using this recipe again!

This was my first time trying it and I hadn't read the comments to see first as I knew that there would be some mixed opinions. I went for it anyway and I followed it step by step and used all of the corrected ingredients but it just didn't rise one bit!! I had to make two to get a good height but I had to bin my first one because it didn't rise and it stuck to the pan! Then on my second on I went to level it with my cake leveller and it fell apart! I will not be using the recipe again!

I started this recipe before reading the reviews. I was surprised it was only 170g recipe when using 20cm sandwich tins and I would say this is the problem with the flat cakes. There is too little mixture in the tins. Smells & looks good but if doing again I would probably make it a 225g butter/sugar/flour recipe to fit the tins better! I have now used exact same recipe to make cupcakes, this recipe makes 24 cupcakes (not muffins) perfectly. I baked in oven same temperature for 15 minutes & they are perfect. I'm going to ice with buttercream & I think there will be some happy birthday boys.

Unfortunately I only read the comments below after I had made 2 failed attempts at this cake. If you follow the instructions exactly it does not rise. I used all the ingredients last night trying to make the cake and today is my kids birthday party and I have 4 flat chocolate disks to show for it. I now see several other people had the same outcome so would suggest you try another recipe.

This is the most yummy chocolate cupcakes. Rise to perfection! Thank you for the recipe. Would definitely recommend it to my friends.
