This is a recipe that I came up with when I had some extra Heath bars. You could use any candy bar...or leftover Halloween candy!!
1 French vanilla cake mix
1/3 c. oil
1/3 c. water
1 c. chocolate chips
2 Heath bars, chopped into small pieces
Combine make mix, eggs, oil, and water. Mix well. Stir in chocolate chips and candy bar. Drop by spoonfuls onto greased baking sheet (or parchment paper...my favorite). Bake at 350 degrees for 10-12 minutes.
