Preparation:

1: Prepare the Crust

1. In a medium bowl, combine the crushed chocolate sandwich cookies and melted butter. Mix until the crumbs are evenly coated.
2. Press the mixture firmly into the bottom of a 9×13-inch dish to form an even crust.
3. Refrigerate for 15-20 minutes to set.

2: Make the Cream Cheese Peppermint Layer

1. In a large mixing bowl, beat the softened cream cheese, powdered sugar, and peppermint extract until smooth and creamy.
2. Fold in the whipped topping until fully incorporated.
3. Spread the cream cheese mixture evenly over the chilled crust.

3: Prepare the Chocolate Pudding Layer

1. In a medium bowl, whisk together the instant chocolate pudding mix and cold milk for about 2 minutes, until thickened.
2. Spread the pudding mixture evenly over the cream cheese layer.

4: Add the Topping

1. Spread an even layer of whipped topping over the pudding layer.
2. Sprinkle crushed peppermint candies, mini chocolate chips, and any additional garnishes on top.

5: Chill and Serve

1. Cover the dish with plastic wrap and refrigerate for at least 4 hours, or overnight, to allow the layers to set completely.
2. Slice into squares and serve chilled.
