Whisk milk and pudding mix for 2 minutes. Let stand for 2 minutes or until soft-set. Stir in chocolate chips, pumpkin and pie spice. Fold in 2 cups whipped topping. Spoon onto crust. Refrigerate for 4 hours or until set. Spread with remaining whipped topping and garnish with almonds and chocolate curls if desired. I made this with pureed pumpkin that Tim and Cat made.
