Preheat your oven to 375. Spray a 13x9 inch baking dish with nonstick cooking spray, then cut a piece of parchment paper to fit inside the dish so that the bottom is completely covered. Spray that with cooking spray too.
Combine the Crisco, vanilla, eggs and sugars and beat until light and creamy.
Add dry ingredients and beat for one minute, or until a thick dough forms.
Stir in chocolate chips and M&M's.
Pour into your baking dish and cook at 375 degrees for 20 minutes.
