Why I Love This Recipe
My sister and I have made these every year for Christmas for the last 7 years. My family absolutely loves them.
Ingredients You'll Need
½ C. margarine or butter
1½ C. graham cracker or other crumbs

Directions
Preheat oven to 350º (325º for glass dish).
In 13x9 inch baking pan, melt margarine in oven. Sprinkle crumbs evenly over margarine mixing them until the crumbs are all moistened then pat them out flat, evenly coving the bottom of the pan; pour sweetened condensed milk evenly over the crumbs.
Sprinkle with chips then coconut followed by nuts; press down firmly.
Bake 25 to 30 minutes or until lightly browned. Cool.
Chill thoroughly if desired.
