For the cake, I used this All-American Chocolate Buttercream cake recipe, but I used 3 cake pans for 3 layers. I also made chocolate buttercream frosting in between the layers and around the cake before applying the fondant.
I also made the characters on top of the cake out of fondant, however I wouldn't recommend it because it was too soft. I would recommend using gum paste if you're wanting to decorate it.
HAPPY BIRTHDAY AJ!!!!!!
To color the fondant you need to buy dye gels, not the liquid food dye, add it to the fondant with a toothpick, and slowly knead the fondant, adding more color if necessary.
