The chocolate cake mixture
Dark chocolate melting in the saucepan to use for decorating

  2. Mix the vanilla cake mix
  3. Mix the chocolate cake mix
  4. Half the cake mixtures and put a bit in each pan to create the marble effect
  5. Cook the cakes for around 30 mins or until brown. If you put in a knife and it comes out clean it is done.
  6. Melt the chocolate and pour the melted chocolate on a tray with baking paper. Add the tray to the fridge to set the chocolate.
  7. Add the icing sugar, 6 teaspoons of dark chocolate cocoa. Add a little water or lemon or apple juice to make the icing mix well.
  8. To make the cheats whipped cream simply add the cream to a blender and choose the chop option. Continue until it looks thick. It will take a couple of minutes, you will be suprised at how quick it is, oh and how simple it is too.
  9. When cakes are cooked and cooled add the whipped cream to the middle of the cake, add the top layer of cake.
  10. Cover the cake with the dark chocolate icing

Post Feast Review

I found this cake very easy to make and all elements came together really well. I did cheat a bit with packet cake mixes but when are a busy mummy this does help you out.

One element that I didn’t get 100% right was the whipped cream in the middle of the cake, I added some cream to the top of the cake but should have kept it all for the middle of the cake. After adding the very dark chocolate icing it did add to the marble effect of the cake.

Having the cream helped with the double layer and allowed a different texture and taste with the bitterness of the dark chocolate.

The addition of the broken dark chocolate shards really topped off the cake visually and also from a dark chocolate lover was a fabulous addition (and between hubby and kids the chocolate on top didn’t last long)

Will I make it again? 

Yes, this is one cake that I would make again no questions asked. I would change it up a little bit and maybe add raspberries to the middle of the cake or possibly blueberries.
