Once these cakes have completely cooled, you can begin assembling. *You may find it easier to bake, wrap, and freeze your cake layers in advance. Then, partially thaw and assemble.
This is the simplified version of our steps. See video to fully understand our process.
Split the 9x13 cake in half. Then, dam & fill the cake with buttercream and stack. (It's on it's own cake board)
Next, trim down loaf cake to form the cab of the truck.
Carve away pieces of cake to form the hood.
Add scrap pieces of the loaf cake to form the bed of the truck (*optional--you could just keep it flat)
Ganache over everything using our simple spreadable ganache (a 2:1 ratio of dark chocolate or semi-sweet chocolate to cream). Chill for 15 minutes in the freezer or longer in the refrigerator to firm everything up.
Then, cover the ganached cake with blue fondant
Layer on accents, add the monster truck cake to wooden structure, using melted chocolate as glue. Add the tires, remaining details, and frosting "mud" to hide anything that needs to be hidden!
