Chocolate Eclair Cake

I got this recipe from a Relief Society activity a while back and I love it!  Definitely a staple for a birthday :)

1lb. Graham Crakers

3 cups of Milk

8 oz. Cool Whip

1/2 cup chopped nuts (optional)

2 pkg. (3oz) Vanilla Instant Pudding

1 tub chocolate frosting

Directions: In a 9x13 inch pan, place a layer of graham crackers.  Mix together milk and pudding mix.  Fold in Cool Whip.  Pour half of pudding mixture over crackers.  Repeat layers, ending with graham crackers.  Melt frosting in the microwave until soft. Spread over graham crackers.  Sprinkle with nuts if desired.  Refrigerate 12 hours before serving.
