Monster Truck Cake

Learn how to make a monster truck cake! This is perfect for young birthdays or for fans of monster trucks! Learn the basics in this tutorial to recreate our cake, or to make it your own!
Course: Dessert
Cuisine: American

Ingredients

  • 9x13 cake layer o your choosing
  • Loaf cake -Ours is 8 ⅜" x 4 ⅜" use whatever you have- you can carve it down as needed.
  • cake cardboard or foam core which you'll later cut to the size of the cake
  • Ganache We used a 2:1 ratio of chocolate to cream--simple spreadable ganache
  • Fondant- I used Duff's pre-colored blue fondant to cover the truck. Black pre-colored Satin Ice fondant for strip around base of cake. Grey fondant for bumper grill and misc accents. Yellow fondant for lights. Yellow, Orange and Red for flames.
  • Rice Cereal Treats- You could make your own Rice Krispies Treats but we used premade for our tires. We used 6 of the 22 gram RKTs per tire! Then at the end of the video we used 4 more pieces to boost our tires a little higher.
  • Chocolate Royal Icing & crushed chocolate and/or honey graham cookies--*Optional--this is what I used for MUD and dirt. Chocolate Buttercream would work as well!
  • Frosting Sheet/Edible image printer--OPTIONAL-- I printed off the truck's name.
  • FMM Multi Ribbon Cutter- Optional -- I use this for easily cutting uniform strips of fondant.
  • Miscellaneous Tylose powder optional, I like to knead a little into decorative fondant pieces, Sugar Glue (aka tylose glue) or your "glue" of choice, X-acto or other sharp knife, "The Mat"-optional.
  • vodka or lemon extract for painting, misc paintbrushes (optional), toothpicks, coloring gels of your choice for fondant accents

For the Wooden Platform (See our post for alternative)

  • We made a sturdy wooden platform to create the space beneath the cake. An easier alternative would be to cover a styrofoam block with black fondant or a black plastic tablecloth to create the illusion of space.
  • 1 18"x20" wooden board that is ½ inch thick Covered the top with a brown plastic tablecloth
  • 6 6"x8" wooden board
  • hand drill
  • 4 6x1" screws
  • Wooden dowel, ½ inch thick and cut into 4" sections. They will cut for you at home improvement store. (*later we wished these were 3 ½" to better fit the size of our tires. Ideally, the top of the tires will be slightly taller than your platform.

Instructions

  • 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!
