Ingredients :
250g self-raising flour
300g caster sugar
3 heaped tbsp cocoa
generous pinch bicarbonate of soda
250g butter
250ml coca cola
125ml milk
2 eggs, beaten
1 tsp vanilla extract
For the icing
100g/3½oz butter
2 tbsp coca cola
2 tbsp cocoa
200g icing sugar
Directions :
Heat the oven to 180C. Sift the flour, sugar, cocoa and bicarbonate of soda into a bowl.
Melt the butter and cola drink gently in a pan then add to the dry ingredients, together with the milk, eggs and vanilla.
Mix gently but thoroughly and tip into a buttered, loose based cake tin (24cm in diameter). Bake for about 40 minutes or until a skewer inserted into the centre of the cake comes out clean.
Remove from the oven and leave for about 15 minutes while you make the icing. Put the butter, cola drink and cocoa into a pan and melt slowly.
Bring the mixture to the boil and then pour onto the icing sugar. Beat until smooth and pour over the cake while still warm.
Cool the cake in the tin.
