1/2 cup butter
14 oz can sweetened condensed milk
1 1/2 cups graham cracker crumbs
11 oz chocolate or butterscotch chips
1/2 cup flaked coconut
1 cup chopped walnuts
In a 13x9 inch pan melt butter in 350° oven. Sprinkle graham cracker crumbs over melted butter. Evenly pour sweetened condensed milk over the top. Evenly top with remaining ingredients. Press down gently. Bake at 350° for 25-30 minutes. Cool and cut into bars.
*I have found that a metal pan works best with this recipe. Glass pans tend to make the graham cracker crust soggy.
