Preheat the oven to 350 degrees.
Pour melted butter into a 9x13 inch baking pan and tilt the pan until the melted butter is evenly distributed around the bottom of the pan.
Add the graham crackers, and press down into the butter to form a graham cracker crust. Add the other ingredients in the order above, one on top of the other.
The sweetened condensed milk is the last layer and holds everything else together. Pour it evenly over the top of the other ingredients.
Bake for 25 minutes or until lightly browned on top.
