My little boy loves monster trucks and apparently he's not alone! When looking for cake ideas I noticed that almost all of the cakes had a THREE candle on top of them. Must be a 3-year-old boy thing! I combined several of the ideas I liked from cakes I found online and got some tips from a friend who made a monster truck cake last year.
Large glazed donuts covered in black frosting, make the wheels. Every mama of boys should have a jar of black food coloring around so she can make racecar/tractor/truck wheels, soccer balls, etc. I put Hershey's Kisses in the wheels for hubcabs.
One gal online had built a wooden platform for her cake. I decided to do something similar. I have a little wooden cutting board that is the size of a loaf pan. I covered it with foil and "glued" four baby food jars to the bottom with honey.
One person had made no-bake cookies for mud. I liked this idea, but knew that with all of the cake and ice-cream, we'd have enough sweets, and Mommy especially doesn't need the temptation of no-bake cookies around! So, I just took a few cups of oats out of my 50# bag and colored them with a couple of Tablespoons of cocoa and about 1/2 C. of water. They look lighter in this pic but they are actually darker and looked just like dirt.
I didn't get pics of the body of the cake. Oops! I used one white cake mix and baked it in two glass loaf pans. I discovered that I could have used two cake mixes because the loaf pans were deeper than I had realized. Be sure to grease and flour the pans well so the cakes come out nicely. Cool completely in the fridge or freezer for a few hours. I dumped out the loaf pans and since one loaf of cake wasn't thick enough I put them together on top of the base board and then took a knife and made a diagonal cut down the front to make the windshield. The piece I cut off was then placed in the middle of the cake body to form the cab of the truck. Then I covered the whole thing in frosting. If I did this again I would probably use a whole cake mix in one loaf pan for the body and then a rectangular chunk of cake added on top from another loaf pan for the cab.
Reese's candies for tail-lights
I used homemade cream cheese frosting. One batch was more than enough for the whole cake. If you purchase your frosting, buy at least two containers of it. Jer wanted a green truck but you could make any color you choose. Laffy Taffy ropes make a nice roll-bar in the back. You can also use sour straws. Foil makes nice windows on the truck. If I ever make another (and no doubt I will with two little boys in the house!) I will add the child's name on the side of the vehicle.
If you want to get more dramatic you can even smash the little cars with a hammer before putting them in the dirt.
