Ingredients You’ll Need
-
For the Cookie Monster Fluff:
- 1 (3.4 oz) package instant vanilla pudding mix
- 1 1/2 cups cold milk
- 1 (8 oz) tub whipped topping (thawed)
- 1/2 cup mini chocolate chip cookies (crushed)
- 1/2 cup mini Oreos (crushed)
- 1/4 cup mini chocolate chips
- 4–5 drops blue gel food coloring
How to Make Cookie Monster Fluff
Step 1: Prepare the Blue Pudding Base
Begin by grabbing a large mixing bowl and whisking together your instant vanilla pudding mix and cold milk. Whisk for about 2 minutes, until the mixture starts to thicken up nicely. Now, it’s time for the magic—add those drops of blue gel food coloring and gently mix until you’ve got an even, vivid blue pudding. This is where Cookie Monster Fluff gets its signature pop!
Step 2: Fold in the Whipped Topping
Next up, add the thawed whipped topping to your blue pudding. Gently fold it in just until everything is combined and the mixture looks soft and fluffy. Be careful not to overmix—you want to keep all that dreamy volume!
Step 3: Stir in the Cookie Mix-Ins
Now for the fun part! Gently stir in the crushed mini chocolate chip cookies, crushed mini Oreos, and mini chocolate chips. These tasty mix-ins give Cookie Monster Fluff all its incredible texture and burst of flavor. Try to distribute them evenly so every serving feels special.
Step 4: Chill Before Serving
Spoon your Cookie Monster Fluff into a big serving bowl (or individual cups if you’re feeling fancy). Cover and chill in the fridge for at least 30 minutes. This helps all the flavors meld together and gives it that classic, cool fluff texture that’s absolutely dreamy.
Step 5: Garnish and Enjoy
When you’re ready to share, top your Cookie Monster Fluff with extra cookie crumbles, a dollop of whipped topping, or even a few more mini chocolate chips for the ultimate finishing touch. Grab a spoon and dig in!
How to Serve Cookie Monster Fluff

Garnishes
Sprinkle extra mini cookies, more crushed Oreos, or a handful of mini chocolate chips on top for that movie-worthy presentation. A swirl of whipped topping or playful blue sprinkles amps up the color and festive factor, making your Cookie Monster Fluff impossible to resist.
Side Dishes
This fluff is a natural standout on its own, but if you want to build a dessert table, try serving it alongside buttery shortbread cookies, fresh strawberries, or a glass of cold milk. It pairs beautifully with just about anything light and sweet, adding a whimsical centerpiece to any party spread.
Creative Ways to Present
Scoop Cookie Monster Fluff into clear cups or parfait glasses for instant party portions, or serve it in a big bowl with colorful spoons for everyone to share. For a cute twist, fill ice cream cones with the fluff—kids (and adults) absolutely love it!
Make Ahead and Storage
Storing Leftovers
Keep any leftover Cookie Monster Fluff in an airtight container in the fridge. It will stay fresh and fluffy for up to 2 days—that is, if you can resist sneaking a spoonful every time you open the fridge!
Freezing
Freezing is not ideal for Cookie Monster Fluff since the texture can separate once thawed, but if you do have leftovers you can’t finish in time, you can freeze it tightly wrapped for up to a month. Just know it may not be quite as fluffy after defrosting.
Reheating
This is a chilled, no-bake treat, so there’s no need for reheating at all. In fact, Cookie Monster Fluff is at its best delightfully cold, straight from the fridge or right out of the serving bowl!
FAQs
Can I use homemade whipped cream instead of whipped topping?
Absolutely! If you prefer homemade whipped cream, just be sure it’s whipped to stiff peaks for the lightest, fluffiest texture. It’ll make your Cookie Monster Fluff taste even more decadent.
What’s the best way to crush the cookies?
Place the mini cookies and mini Oreos in a zip-top bag and gently crush them with a rolling pin or use your hands. You want chunky pieces for better texture, not crumbs!
Can I add marshmallows or other mix-ins?
Yes, mini marshmallows are a delicious addition and make the fluff even more playful. Sprinkles, bits of candy, or even chopped candy bars are fun ways to customize your Cookie Monster Fluff.
Is it okay to use liquid food coloring?
While you can use liquid food coloring in a pinch, gel gives your fluff that bold, Cookie Monster-inspired blue. Gel coloring won’t water down the pudding, so you’ll get a more vibrant look and perfect texture.
How far in advance can I make Cookie Monster Fluff?
You can make it up to a day in advance and keep it covered in the fridge. For the best texture, add extra garnish or cookie chunks just before serving so they stay crisp!
Final Thoughts
Cookie Monster Fluff is one of those desserts that just makes people smile. It’s delightfully easy, wildly fun, and always a hit with kids and grown-ups alike. Give it a try—you might just find your new favorite reason to celebrate!
