By using a prepared graham crust you skip the step that includes mixing butter and graham crumbs to form the crust. Just use a store bought pie crust and that step is done. You do have to be careful baking though as the edges tend to over-bake quickly as you wait for the center to be done. Watch it closely the last 3-4 minutes.
1 graham cracker crust
1 cup semisweet chocolate chips
1 cup butterscotch chips
1 cup coconut
1 cup chopped walnuts
1 can (15 ounces) sweetened condensed milk
Sprinkle the graham layer with the chocolate chips, then the butterscotch, then the coconut and walnuts. Pour the can of sweetened condensed milk over all. I didn't use quite all of the condensed milk, I'd say there was about 1/4 inch left in the bottom of the can. Bake for 24-33 minutes in a preheated 350 oven. Cool completely then cut into pieces. These are very, very rich!
