Preheat oven to 370F.

In large bowl, combine cake mix, oil and eggs; stir by hand until thoroughly moistened. Stir in candy bits from cake mix. Shape dough into 1-inch balls; place 2 inches apart on ungreased cookie sheet. With bottom of glass dipped in flour, flatten to 1/4-inch thickness.

Bake for 6 to 8 minutes or until edges are light golden brown. Cool 1 minute; remove from cookie sheet. Spread frosting over warm cookies. Immediately sprinkle each with candy bits from frosting.
