Preheat the oven to 350°F. Lightly spray a 9x13 inch baking dish with cooking spray and set aside.
In a large bowl, mix together all of the infredients until fully combined.
Pour the mixture into the prepared baking dish, and place in the preheated oven for 20-25 minutes, or until a toothpick inserted comes out clean. Allow to cool completely in the pan before cutting into squares.
