A couple of weeks ago I posted on here asking if anyone could give me some help in baking a wedding cake. I am happy to say I have made a three tier cake. Lemon on the bottom. Vanilla for the middle and chocolate on top. I found a fantastic site Cakes bakes and cookies. Where I got the basic recipes for the different sizes of maderia cakes I used. Now I have to decorate and the happy couple want the cake covered in buttercream. Has anyone done this before and is it just the basic recipe, icing sugar and butter?
