Place all the ingredients into a high powered blender and whizz until you have a completely smooth paste
If you want to have a no-bake chocolate pudding, place the mixture into four serving dishes
If you want to make a cake, scoop the mixture into a small cake tin (mine was around 12cm diameter) and cook for 15 - 20 minutes (depending on the size of your tin) at 180 degrees (160 degree fan, gas mark 4)
Cool then place in the fridge to set before cutting
