This is a lovely cake for the weekend and was certainly polished off quick in this household !
10oz self-raising flour
2oz cocoa powder
1 cup oil
1/2 pint water
1 mashed banana
Mix all the ingredients together and place in a greased 9 in square or round tin. It makes quite a lot of mixture so you might want to use 2 tins depending on how deep they are. (If you do make 2 then you can sandwich them with buttercream icing afterwards which is good for a special occasion.)
Bake for 40 minutes at Gas Mark 5 or 180C. Leave to cool in the tin and enjoy !
