It wasn't easy to choose between the frostings. The butterscotch was creamy and rich. The chocolate was smooth and would finish up similarly to the buttercream I was used to working with for my cake decorating classes, making it ideal for decorating. So, what's a girl to do? Use both, of course!
I set out the cake on a serving board, and layered the cakes with butterscotch icing for the filling.
