I made this Elphaba from Wicked Cake for my daughter’s fifth birthday. I used a sheet cake, placed a wicked printout directly on the cake, poked small holes in the outline with a toothpick to create the shape. Very simple.
My biggest challenge was coming up with black frosting as the stores had already closed when I was decorating this. The frosting is actually a very dark purple, but no one noticed. My daughter loved the cake!
