1 devil's food cake mix (Duncan Hines works best)
1 c. graham cracker crumbs
1/4 c. melted butter
1 c. (6 oz.) chocolate chips
3/4 c. chopped nuts
Cool Whip

Mix graham crumbs, butter, chocolate chips and nuts. Prepare cake according to directions, putting in two round layer pans. Sprinkle crumb mixture over cake batter before baking at 350 degrees for 30-35 minutes. Cool in pans 15 minutes; remove and cool on rack, crunch side up.

Spread Cool Whip between layers and on sides only. Chill before serving.
