This cake has a one layer 10" chocolate cake and the tub (also chocolate) is a 3 layer 8" x 3" cake. It stacked up nicely. The cake is covered in French Vanilla Buttercream and coated in MMF. The decorations are also MMF with the exception of the plastic toy duckies. The bubbles are buttercream with a white shimmer petal dust on them. I am a little bummed that the bubbles didn't show the shimmer dust very well. I was going to use MMF for the bubbles, but I ran out of fondant. I pulled an all nighter making this cake and thought that using buttercream instead was a good call for my sanity. Maybe on the next cake :)
