This is a truly faboo desert that everyone will enjoy. It’s also a very long one to make — do not wait until 8 p.m. the previous night to start making it, because the various layers have to set in the fridge at each step.
Ingredients:
1½ sticks Butter, melted
1½ c Flour
1 c Pecans, chopped
—
8 oz Cream Cheese
1 c Powdered Sugar
2 c Whipped Cream
—
6 oz Instant Chocolate Pudding Mix
6 oz Instant Vanilla Pudding Mix
4 c Milk
…
Chocolate sprinkles, shavings, or chopped semi-sweet chocolate chips
You can substitute walnuts for pecans. You can also substitute Cool Whip for the whipped cream (but it’s not as good).
Instructions:

• Crust: Mix butter, flour, nuts. Press into 9×13 baking pan. Bake 20 min. at 400°.
• Layer 1: Fold together cream cheese, powdered sugar, 1 c of whipped cream. Spoon over crust. Refrigerate until set.
• Layer 2: Mix chocolate pudding mix with 2 c milk. Spoon onto cream cheese mix. Refrigerate until set.
• Layer 3: As Layer 2, only with vanilla pudding mix.
