Preheat the oven to 350 degrees.
While the oven is preheating, melt the butter in a 9x13 baking pan.
Crush the graham crackers in a food processor or baggie.
Sprinkle the graham cracker crumbs evenly over the butter in the bottom of the pan, press lightly into the butter.
1 1/2 cups graham crackers, crushed, 1/2 cup butter, melted
Evenly cover the crust with the coconut flakes, chocolate chips, butterscotch chips, and pecans. Drizzle the sweetened condensed milk evenly over the top.
1 cup coconut flakes, 1 cup semi-sweet chocolate chips, 1 cup butterscotch chips, 1 cup pecans, chopped, 14 oz sweetened condensed milk
Bake for 20-25 minutes. Watch it closely until the edges are golden brown. You want to be careful not to burn the coconut and it can happen very quickly.
Let cool about 5 minutes and run a knife around the edges of the pan to prevent sticking.
Allow to cool completely before slicing into squares.
