This was a really fun one to do. The Birthday girl, a good friend of ours, wanted to not only design her own birthday cake, but help make it. She made the chocolate accent pieces on the cake and helped with the frosting. The 10" round yellow cake was plenty to feed the birthday group. The cake was a little tricky to frost with the butter cream on the inside, and I ended up using a butter knife. I brought three sparkly gel icing pens to the party and the kids had fun decorating the cake board.
