Step 1

Preheat the oven to 350 degrees F. Coat a 9-by-13-inch baking pan with cooking spray and set aside.

Step 2

Stir together the graham cracker crumbs, melted butter and salt in a medium bowl until thoroughly combined. Press the crust mixture into the bottom of the prepared pan in an even layer.

Step 3

Sprinkle the dark chocolate chips, butterscotch chips, white chocolate chips, pecans and coconut over the crust. Pour the condensed milk evenly over the top, and spread with a spatula to make sure everything is even.

Step 4

Bake until the edges are golden brown and the middle is set, 25 to 30 minutes. Let cool completely before slicing.
