Chocolate Layered Dessert

1 pkg Chocolate Tiramisu Dip Mix
1 pkg (8 oz) cream cheese
1/4 cup milk
1 pkg (8 oz) Cool Whip
Chocolate graham crackers

Using an electric mixer, beat the dip mix and cream cheese until light and fluffy. Slowly beat in the milk until smooth. Blend in the Cool Whip until well incorporated. Spread 1/3 of the mixture into the bottom of an 8 inch by 8 inch (or similar) dish. Place single layer of graham crackers over the mixture. Repeat for second layer. Spread remaining mixture on top. Garnish with chocolate sprinkles, or graham cracker crumbs. Chill for at least 2 hours (overnight is better).
