1. Preheat oven to 350 degrees. Unwrap the 3 MUSKETEERS Brand FUN SIZE® Bars. Set six candies aside and chop the rest.
2. Prepare the cake mix according to the directions on the box. Fold the chopped candies into the batter before transferring to two 8-inch cake pans. Bake for approximately 30 minutes.
3. Cut the round cake in half and place the 2 halves on either side of the square cake to form an oval.
4. Set 3/4 cup of vanilla frosting aside. Spread the cakes with the remaining vanilla frosting. Reserve 1/2 cup of M&M'S® Brand Milk Chocolate Candies. Cover the sides of the cakes with M&M'S® Brand Milk Chocolate Candies. Sprinkle the top with a track of chocolate cookie crumbs. Arrange the yellow M&M'S® Brand Milk Chocolate Candies as the dotted line on the track.
5. Divide the reserved frosting into 4 or 5 bowls and tint each bowl a different color. Spoon colors into resealable bags. Snip a corner and pipe numbers on top of the reserved 3 MUSKETEERS Brand FUN SIZE® Bars. Attach matching color M&M'S® Brand Milk Chocolate Candies for the car's wheels.
