  • 100 g light brown soft sugar
  • 250 g caster sugar
  • 4 medium eggs
  • 350 g plain flour
  • 60 g cocoa powder

  • Preheat the oven to 180ºC.

  • In a large mixing bowl cream together the butter and sugars until light and fluffy.
  • Add the eggs and mix in.
  • Sieve the flour, cocoa powder, baking powder and the salt in to the mixing bowl and mix well together.
  • Stir in the milk and add some flour if the mix starts to seperate.
  • Pour the mix into the prepared tin and level out. Gently tap the tin on the worktop to remove any air bubbles.
  • Bake fro 35-40 minutes until the centre of the cake is cooked - use a cake tester or skewer to check. If the tester comes out clean the cake is cooked. If it has pieces of uncooked cake on leave the cake to cook for a few minutes more and test again.
  • Leave in the tin to cool for 30 minutes and then remove from the tin to cool completely.

Chocolate Cream Cheese Buttercream

  • Make sure the unsalted butter is at room temperature as it will help make it a lot easier to make.
  • Using a hand mixer, mix the butter and icing sugar.
  • Add the cream cheese and create a smooth mix.
  • Sieve in the cocoa powder and mix in. If the mix is very thick add a splash of milk and mix again.
  • Smear the chocolate cream cheese buttercream thickly over the cold cake.
  • Decorate with your favourite Halloween candy and sweets.


•The cake will last for up to 5 days in an air tight container.
•Store somewhere cool but not the fridge.
•For the best results use the eggs and butter from room temperature.
