Everyone will love the soft and chewy texture of the bars and delicious peanut butter and white chocolate flavors.
The cookie dough is made by mixing a box of cake mix with eggs, vegetable oil, and peanut butter until smooth. Fold the M&Ms and white chocolate chips into the cookie dough, and press it evenly into a greased square baking dish. Bake until the center of the cookie bars comes out clean with a toothpick.
