Preparation:

1: Prepare the Pudding Base

1. In a large mixing bowl, whisk together the instant vanilla pudding mix and cold milk for about 2 minutes until the mixture begins to thicken.
2. Let the pudding sit for 5 minutes to fully set.

2: Fold in the Whipped Topping

1. Gently fold the whipped topping into the pudding mixture until light and fluffy.

3: Add the Mix-Ins

1. Stir in the crushed Oreos, crushed candy canes, and mini marshmallows until evenly distributed.

4: Chill the Fluff

1. Transfer the mixture to a serving bowl and cover with plastic wrap.
2. Refrigerate for at least 1 hour to allow the flavors to meld and the fluff to firm up.

5: Garnish and Serve

1. Before serving, top the fluff with additional crushed Oreos, crushed candy canes, and a dollop of whipped cream.
2. Garnish with mini candy canes for a festive touch.
3. Serve chilled with cookies, crackers, or fresh fruit for dipping.
