A close friend of mine, Karen and her twin sister Kathy recently celebrated their 50th birthday. Kathy lives out of state, but every ten years they celebrate together. Their mom said they had always had two different cakes growing up, so she wanted to keep that tradition, but also wanted me to have a little fun and be mean. I initially had the idea of making a number cake, but stumbled on this angel/devil idea online. It was perfect!
