You place the following, in order, into a mixing bowl;- 1 cup sugar, 1 egg, half cup milk, half cup melted butter, 4 tspns cocoa or coffee, 1 tspn baking powder, 1 tspn baking soda, 1 tspn vanilla essence, 1 and a half cups plain flour, half cup boiling water.
You;- beat hard for 3 mins with electric mixer. Bake in greased and lined tin - good in loaf tin if cutting into slices for freezing. The cake mix is quite runny - this is fine; it turns our perfect every time. (180 degrees celcius for 35-40 mins approx). Cool, and ice with butter icing.
We also made Vanilla Cup Cakes; it's quite easy then to make up a double batch of butter icing and just add coffee/cocoa to one half.
Another good one to try is Caramel Cup Cakes.
