Share a little about the materials, processes, and techniques used to create this cake I tried to incorporate my grandson's love of monster trucks and Santa in his birthday cake. Santa and his sleigh are made of modeling chocolate and the decorative trim is fondant and gumpaste. I painted the trim using gold luster dust mixed with gold disco dust to give it that extra shimmer. The cake is buttercream with glitter crystals sugar sprinkled on for snow. This was a fun cake to make but the best part was seeing Carter's face light up when he saw his cake! He would sit and gaze at his cake for the longest time, and of course sneak a finger (or two) of icing when we were not looking!
