1cupEaster M&MsI used peanut, plus more for decorating
Instructions
Preheat the oven to 350 degrees and spray a 9x13 baking pan with nonstick cooking spray. Stir together the cake mix, eggs, butter, water, and vanilla extract.
Fold in the chocolate chips.
Spread the batter into the prepared pan. Top with M&Ms.
Place in the preheated oven and bake for 20 minutes, until a toothpick inserted into the center of the cookie bars comes out clean.
Remove the pan from the oven and immediately top with additional M&Ms, if desired. Lightly press the candy into the top of the cookie bars, then allow them to cool completely.
When the cookie bars are cool, cut into 15 pieces or smaller if you want more, to serve.
