Place pan with butter in the oven. Melt the butter in the pan while preheating. It will take about 5 minutes.
Crush graham crackers in a food processor to create graham cracker crumbs
When butter is melted, remove pan from oven and carefully sprinkle the graham cracker crumbs over the melted butter. Press lightly with the back of spoon.
Pour sweetened condensed milk over the crumb layer.
Sprinkle 1/2 cup of the chocolate chips, 1 cup of the M&M's over the sweetened condensed milk layer. Sprinkle all of the coconut on top, followed by remaining chocolate chips and M & M's.
Bake in your oven for 25-30 minutes or until a little brown. Remove from oven and allow them to cool completely.
Notes
I love chocolate and peanut butter. I you are looking to switch things up, here is what I recommend:
add 1/3 cup creamy (or chunky) peanut butter to the crust batter.
add peanut butter chips.
add Reese’s Pieces instead of M & M’s (or do both. I won’t judge).
add Reese’s Peanut Butter Cup pieces to the batter.
