Line bottom of an ungreased 13- x 9-inch baking dish with one-third of honey graham crackers.
Whisk together pudding mix and milk; add whipped topping, stirring until mixture thickens. Spread half of pudding mixture over graham crackers. Repeat layers with one-third of graham crackers and remaining pudding mixture. Top with remaining graham crackers. Spread with chocolate frosting. Cover and chill 8 hours.
Note: To lighten, use reduced-fat graham crackers, sugar-free pudding mix, fat-free milk, and fat-free frozen whipped topping.
