1. Preheat the oven to 160C (315F, Gas 2-3).
2. Grease the cake tins and line the base with greaseproof paper, line the sides of the tin so that the sides extends about 2 cm (3/4 inch) above the height of the tin.
3. In a saucepan place the butter, chocolate, coffee and water, stir over low heat until melted, remove from the heat allow to cool.
4. Mix the eggs, oil and buttermilk combine well.
5. In a large bowl sift the flours, cocoa powder and bicarb soda.
6. Stir in the sugar and make a well in the center and add the chocolate, butter mixture and the egg, buttermilk mixture, stir until completely combined.
7. Pour the mixture into the prepared cake tin.
8. Bake for the required time, refer to chart below for your selected cake size.
9. Test the cake toward the end of cooking time. The cake is cooked when a skewer inserted into the center of the cake comes out clean.
10. Leave the cake to cool in the tin. When cold turn out of the tin and remove the paper.
The chocolate mud cake can be stored in an airtight container in the fridge for up to 3 weeks or freeze for up to 2 months. Allow the cakes to come to room temperature before decorating.
If you are using an unusual cake tin and are unsure of the quantity of the cake mix to use, you can easily work out the quantity by measuring the volume with water.
To do this completely fill a 20 cm (8 inch) round cake tin with water, then pour this into the shaped tin until completely full.
This way you can calculate how many quantities of the basic 20 cm (8 inch) mixture will be needed to fill the tin.
