Lay 3 whole Rice Crispy Treats on a parchment lined baking sheet.
Cut another one into a half piece treat and two others into third-size treats and lay each on the tray with the whole treats. You now have 3 sets of treats.
In 3 separate bowls, melt each color of chocolate. Heat for 30 seconds at a time, stirring between times, until completely melted.
Dip the first set of treats that has a whole piece and the half piece into the brown chocolate, completely coat. This set will be Mater.
Set the smaller piece on top of the whole piece to resemble a car windshield.
Repeat this step with each of the other sets and each colour of chocolate. These will be Lightning McQueen and Luigi.
Using the Airheads candy, cut 3 windshields to fit onto the cars. I made mine rectangle with little cut outs at the top to resemble the Cars characters. Press these on each car.
Cut a mouth out of the candy for the red and yellow car. Press this on the bottom piece of the car where the bumper would be.
Pull apart the Oreo cookies, and press 4 on each car. Use green, blue, and brown M&M’s for the eyes. Put a dab of melted chocolate on the backs and press on the windshields.
On the brown truck, put a line of chocolate on the bottom piece and place 2 gum teeth where the bumper would be.
Extra optional steps are: Pipe a line of chocolate on the yellow car over his mouth to resemble a moustache. Use an edible marker to put black dots on the eyes.
Notes
Use Rice Krispies Treats as the base for your cars. Cut them into various sizes to create different characters like Lightning McQueen, Mater, and Luigi.
Melt colored candy melts (red, yellow, and brown) to coat the Rice Krispies shapes, giving each character its signature color.
Decorate with mini Oreo wheels, Airheads for windshields, and M&M's for eyes to bring your edible cars to life.
