This cake was made for a very dear friend of mine. She was turning 35 and needed her spirits lifted. I used just basic round pans in different sizes, and didn't center them. This is a 3 layer yellow cake decorated with buttercream icing colored with Wilton gel colors. The doll, towel, and extra decorations on the steps are the only inedible parts of the cake. The "bubbles" in the hot tub are buttercream icing.
