I make this -it is quite an old American recipe that my mother gave me: 1/2 cup cocoa(NOT drinking choc),1 cup SR flour,1 cup sugar -1/2 white,1/2 soft dark brown,1/2tsp baking powder,pinch salt. 1/3 cup veg oil or melted marg,1/4 cupmilk,1/2 tsp vanilla,1 egg. Beat wet ingrediants well,then add dry and mix until combined-pour into floured and greased 8" tin,bake for aprox 40 min.......double this if you want to make a layer cake. I cover it with either a choc buttercream, or I mix 1cup cocoa with 1 1/2 cups icing sugar-to this I add water a bit at a time until it is the consistancy of thick custard-beat well....pour onto the cake and spread gently so it runs down the sides.
