My instructions were 'chocolate' so first I've experimented with different chocolate cake recipes to find a soft, moist, rich cake. The winner uses blackcurrant jam in the recipe instead of the vegetable oil used in most of the recipes I trialled, and it is delicious!
I have decided chocolate frosting on chocolate cake is not the prettiest as there is no contrast, so I've been practising with dual-coloured piping, and it's not perfect yet but I think it's the way to go - chocolate and vanilla swirled together, yum.
For decoration, they are having rainbow colours at the wedding so I'm going to just go crazy with flowers and butterflies and birds.
I can't wait!
