This is for a co-worker's dad who's birthday is today, so she wanted a football theme. This is a 9x13 cake, buttercream icing, oreo mousse filling, and chocolate footballs for decoration. It was a smaller cake than I thought and feeling guilty charging her $40, so that is why I put in the filling. She wanted vanilla cake with chocolate icing, but used my regular vanilla buttercream.....but had chocolate cake scraps left over and used them like a spackle (al la Toba Garrett) under the icing for a coating.
