Chocolate Fingers and Smarties Birthday Cake

Happy Birthday to my amazing boyfriend James who turned 26 on Tuesday! You’re never too old for birthday cake, so I decided to bake him up a chocolately treat!

Chocolate Fingers and Smarties Cake

This is without a doubt the best cake I’ve made to date. Everything went smoothly and it looked and tasted amazing!

Underneath the smarties and behind the chocolate fingers you’ll find a delicious chocolate cake covered and filled with dark chocolate ganache. Heaven.

Struggling for ideas for a birthday cake? Why not give this a go? You can also swap the chocolate fingers for kit kat fingers and the smarties for m&ms or maltesers.


For the cake:

  • 250g plain flour
  • 200g caster sugar
  • 1 tsp baking powder
  • ½ tsp bicarbonate of soda
  • 40g cocoa powder
  • 175g soft butter
  • 2 eggs
  • 2 tsp vanilla extract
  • 150ml sour cream

For the ganache:

  • 300g double cream
  • 300g dark chocolate, broken into small pieces (I used Green and Blacks but you can also substitute for milk chocolate)


  • Chocolate fingers (2 packs)
  • Smarties (pack of 4)


1. Preheat your oven to 180C,350F,gas mark 4 and grease and line a round cake tin.

2. In a large mixing bowl, cream the butter and sugar together until light and fluffy.

3. In another bowl, whisk together the cocoa, sour cream, vanilla and eggs and add this to the bowl of sugar/butter. Keep whisking until it is all combined and smooth.

4. Next add the flour, baking powder and bicarbonate of soda until you have a well combined and creamy mixture. Be careful not to overbeat the mixture.

3. Spoon your cake mixture into the prepared cake tin and pop in the oven for about 35 minutes. To check that the cake is done, insert a skewer through the middle. If it is done it should come out clean.

4. Leave to cool in the tin for 15 minutes before turning out onto a wire rack to cool completely.

5. To make the ganache for the outside and filling of the cake. Gently heat the cream in a saucepan until it starts to bubble. Remove the pan from the heat and then add the chocolate bits. Stir quickly until the chocolate has completely melted into the cream. Leave to cool for about 1 hour until the mixture has thickened.

6. When your cake is fully cool, gently slice the cake in two. Place one of the cakes onto a plate and spoon small heapfuls of the ganache onto the cake. Spread it evenly and then place the other half of the cake on top.  Spoon the rest of the ganache over the top and sides of the cake so it is fully covered.

7. To decorate, stick the chocolate fingers all the way round the cake and cover the top of the cake with the Smarties.

Enjoy with family and friends!
