Let’s whip up this classic Oreo Fluff:

1. Prepare the Pudding Base:

• In a large mixing bowl, pour in the 2 cups of cold milk.
• Add the dry instant vanilla pudding mix powder to the milk.
• Whisk vigorously for about 2 minutes, ensuring all the powder is completely dissolved and the mixture begins to visibly thicken.

2. Let Pudding Set Briefly:

• Let the thickened pudding mixture sit undisturbed at room temperature for about 5 minutes. This allows the pudding to fully set and reach its maximum initial thickness.

3. Fold in Cool Whip:

• Add the thawed Cool Whip to the set pudding in the bowl.
• Using a rubber spatula, gently fold the Cool Whip into the pudding. Use large, sweeping motions, bringing the mixture up from the bottom and folding it over the top, rotating the bowl as you go. Continue folding just until no streaks of pudding or Cool Whip remain and the mixture is uniform and fluffy. Avoid stirring vigorously to maintain the light, airy texture.

4. Prepare and Add Oreos:

• Coarsely crush the Oreo cookies. You can do this by placing them in a zip-top bag and gently crushing them with a rolling pin or the bottom of a glass, or by pulsing them a few times in a food processor. Aim for a mix of smaller crumbs and some larger, bite-sized chunks.
• Reserve about 1/4 cup of the crushed Oreo cookies for garnishing the top later.
• Gently fold the remaining (larger portion) of crushed Oreo cookies into the pudding/Cool Whip mixture until they are evenly distributed.

5. Fold in Marshmallows (Optional):

• If using, add the mini marshmallows to the bowl.
• Gently fold the marshmallows into the Oreo fluff mixture.

6. Transfer and Garnish:

• Transfer the prepared Oreo fluff to a serving bowl.
• Sprinkle the reserved 1/4 cup of crushed Oreos evenly over the top for garnish.

7. Chill to Set:

• Cover the serving bowl with plastic wrap.
• Refrigerate for at least 1 hour before serving. This allows the flavors to meld and the dessert to chill and set fully.

8. Serve:

• Serve the Oreo Fluff chilled.

An incredibly simple and fun dessert to make
