Mix powdered sugar, peanut butter, and cream cheese together. Add 1/2 the whipped topping and mix until well blended. Divide mixture between two pie crusts. Blend milk and instant pudding together for 2 minutes. Pour pudding into the two pies and spread out evenly. Spread remaining whipped topping over top of the two pies. Garnish with chocolate shavings or sprinkles. Note: Can be frozen until close to serving just to make them firmer and easier to cut and serve. From Chris, An Ohio Tailgater
