My friend wanted an all buttercream cake done in tie dye for her little girls b'day, I had no idea where to even begin! I ended up doing circles and abstract with the different colors and then went back with a toothpick and dragged the colors together at the edges. The peace sign is cut out of the top layer of the cake, while the bottom layer was left in one piece. It's a 10" white cake. I also tie dyed the inside by coloring the batter the same as the icing and dropping it by spoonfuls into the pan. PM me if you'd like a picture of it, it's amazing!
