If you prefer to make a whole cake, this same quantity of mixture will fit an 8 inch round cake pan. Prepare the pan by brushing with oil then make the cake in the same way as the cupcakes, above. The whole cake will take nearer 45 minutes to cook - test in the same way by pricking in the middle. You will probably need more of the glaze than suggested here as this gives a light coverage of the cupcakes (as you can see in the pictures) so to give a fuller glaze of a whole cake, you will need nearer double.
