My first topsy turvy. I just wanted to see if I could do it. The construction was not as difficult as I thought but I did learn one important thing. Don't ice a frozen cake and expect it to crust within 7 to 10 minutes. It is a peanut butter cake with chocolate buttercream icing. The funky blue color is because I was too lazy to make a white buttercream and it was only for fun anyway. I know it is not perfect, but I learned a lot and I am looking forward to trying again for real.
