This was for a friend's little boy. He LOVES Umizoomi. The smash cake is just a white cake with buttercream icing. Geo's face is mmf. It was fun to make! The bigger cake, with all the characters, is yellow butter cake with ganache filling and is covered in buttercream. All characters were made from mmf. All the little details were very time consuming, but well worth it when it all came together. The bigger cake was inspired by a cake that I found online. TFL!
