Heat oven to 350 Degrees
Spray a 9x13 inch baking dish with non stick cooking spray and set aside.
Melt butter in a small bowl in the microwave or in a saucepan on the stove.
Remove the butter from heat and stir in graham cracker crumbs until thoroughly combined. Press the graham cracker mix onto the bottom of the pan. (A rubber spatula is helpful when pressing it down)
Pour the sweetened condensed milk evenly over the graham cracker mixture. If needed, use a spatula to spread it to the edges of the pan.
Sprinkle the Coconut Flakes, Chocolate Chips, Butterscotch Chips and M&M’s over the condensed milk
Gently press your ingredients into the condensed milk, it will hold everything together.
Bake in preheated oven for 25-30 minutes until edges are golden brown and the middle is set.
Allow to cool completely before slicing, about 2 hours.
