Use my DIY Edible Cake Paint for this cake
I frosted my entire cake white and then painted the red and yellow and black. Then with the rest of my frosting I made it yellow and used my piping bag and tips for the stripes and accents (using this amazing technique to fill the piping bag). I needed about 1.5 batches of frosting (buttercream recipe from the Betty Crocker cookbook).
I used a toothpick to draw on the white frosting so that I knew where to paint. If you mess up with the toothpick just run a butter knife in warm water and smooth it out and do it over again.
To make the dump truck cake (I got my inspiration for this cake here) I used 1 cake mix divided between a regular bread pan and a mini loaf pan. I leved the top of the big one to make it flat and just cut the ends off the mini loaf so that it was the same width as the bottom of the truck. I left the round top on the mini loaf. I used the cookie part of oreos to make the dirt and mini chocolate donuts for the wheels. The entire cake cost me less than 5 dollars to make.
