How to Make Chocolate Biscuit Cake

In a medium sized saucepan add the butter. Cut it into a few pieces just so it will melt easier.

Add in the dry ingredients, the cocoa powder and the sugar.

Pour in the water and place the saucepan over medium low heat.

Stir occasionally as the ingredients melt together. When the mixture is completely smooth remove it from the heat and set to the side.

Using a food process or just your hands break the biscuits up into small pieces. Variety is great here so keep some pieces larger and some pieces pretty small.

Pour the melted chocolate mixture into the bowl with the broken up biscuits.

Using a wooden spoon combine everything together really well until you can no longer see and dry pieces of biscuits. It’ll look like a bit of a mess but don’t worry it’ll come together into a delicious cake.

Add the mixture to lined 8″ or 20cm cake pan and press down really well with the back of a spoon. Place it into the fridge to set while we make the topping.

To make the icing chop the chocolate up small and add to a small bowl. Heat the cream over medium heat until it just comes to the boil and pour over the chocolate. Leave for about 3-4 minutes to melt before adding the powdered sugar on top. Stir to combine until completely smooth.

Pour the icing over the Chocolate Biscuit Cake and place in the fridge for at least 6 hours or overnight to set.

Common Questions about this Chocolate Biscuit Cake Recipe

What are Digestive Biscuits?

Digestives are common in NZ, Australia and Europe. They are vary similar to Graham Crackers so use whichever you can get your hands on. Alternatively you can use another type of cookie or biscuit for your choice, I would recommend something simple and plain like tea biscuits or vanilla cookies.

Can I make this into a log or slice?

Yes definitely! You can pour the cake mixture into any kind of pan or tin you would like or use baking paper to shape into more of a log. You can as well halve the recipe if you would like to make a smaller amount.

Yes, thats what makes this recipe so great! You can add anything else you would like or have on hand. Nuts and dried fruit work incredibly well in this recipe.
