I made these bars for our Pinewood Derby concessions and they were a big hit. Such a big hit that I didn't even get a peice to try. So, I had to make them again. Such a simple recipe with amazing results!!! You will love them.
I found the recipe on pinterest.
1 box yellow cake mix
1 small box instant vanilla pudding
1/4 cup water
3/4 cup vegetable oil
1 cup chocolate chips (you could use M&Ms too)
Preheat oven to 350 degrees.
Combine all ingredients in large bowl. It will be thick! Pour batter into a greased 9x13 baking dish. Bake for 25-30 minutes or until edges are golden brown.
