I made this cake for my daughter's 4th birthday party, used 4 9x13 cake pans (didn't have my sheet cake pans yet), the cakes made the base, then I used the Wilton butterfly cake pan as the top, all buttercream, the topper, is white chocolate candy melts, made into the number 4 using the number 4 mold, covered with pink pearl dust. Antennas, are lollipop sticks, rolled into candy melts, with small edible pearls on the ends. New to the cake thing, and was super proud of this one, was a huge hit!!
