I used a large sheet cake pan-- took 3 mixes to fill. Buttercream icing and edge in white dots. Fondant colored circles. I cut the letters out of fondant and secured the up-right ones onto toothpicks using the same color royal icing-- worked well. BTW, I used a recipe for fondant using marshmallows-- very tasty! Elmo is made from 3D bear pan using 1mix. Elmo's eyes and nose are solid fondant secured w toothpicks, his mouth flat fondant. Warning: the cake was very heavy and I needed a thick board to support it. The Big Bird candle was purchased at a cake store.
