Combine the crust ingredients in a bowl and toss to combine. Press the mixture into the bottom of a 9 X 13-inch baking pan coated with cooking spray.
Meanwhile, in a large bowl, combine the remaining ingredients and beat thoroughly until no lumps remain. Pour the filling over the graham cracker crust. Bake in a preheated 350-degree oven for 30 minutes and cool on a wire rack before transferring to the refrigerator to chill.
Top as desired or enjoy it as is.
