Preparation Phase & Tools to Use

Before diving into mixing, let’s talk setup. You’ll want to have a large mixing bowl handy—it allows you to fold all your ingredients without spillage. A hand mixer or stand mixer will make quick work of whipping the cream cheese and blending the peanut butter smoothly. A rubber spatula is essential for folding without deflating the whipped topping.

You’ll also want a serving bowl that’s wide and shallow. This helps display all those dreamy peanut butter swirls and chopped Reese’s cups. If you’re taking it to go, a lidded container keeps things tidy while traveling.

Ingredients for the Reese’s Peanut Butter Fluff

• Cream Cheese: This forms the rich and tangy base, adding structure and a luscious texture to balance the sweetness.
• Peanut Butter: The star of the show. It gives the fluff that signature nutty depth and a hint of saltiness that cuts through the sugar.
• Powdered Sugar: Essential for sweetening the base without adding grit. It blends in seamlessly.
• Whipped Topping (like Cool Whip): Adds the “fluff” in the fluff. Lightens the mixture and makes it airy and scoopable.
• Mini Marshmallows: Brings extra softness and bounce, making every bite more fun and pillowy.
• Reese’s Peanut Butter Cups: Chopped and folded in for texture, richness, and chocolatey contrast. Reserve some for topping too.
• Vanilla Extract: A small addition that deepens flavor and enhances the peanut butter and cream cheese.

How To Make the Reese’s Peanut Butter Fluff

Step 1: Whip the Creamy Base

In a large mixing bowl, beat the cream cheese until smooth. Add the peanut butter and powdered sugar, mixing until completely blended and fluffy.

Step 2: Fold in the Whipped Topping

Use a rubber spatula to gently fold in the whipped topping. Take your time to keep the mixture light and airy.

Step 3: Stir in the Goodies

Add the mini marshmallows and most of the chopped Reese’s. Fold them in evenly so every scoop gets a hit of chocolate and marshmallow.

Step 4: Chill and Serve

Transfer the fluff to a wide serving bowl. Top with remaining chopped Reese’s for presentation. Chill for at least 1 hour before serving to let the flavors meld.

Serving and Storing Your Reese’s Peanut Butter Fluff

This dessert is best served chilled, ideally after an hour or two in the refrigerator. It gives the flavors time to meld and the texture to firm up just enough. Serve it in a large bowl with a big spoon and let guests scoop their own portions into cups or onto dessert plates.

It also works wonderfully as a sweet dip—pair it with graham crackers, pretzels, or apple slices for contrast.

To store leftovers, cover tightly with plastic wrap or transfer to an airtight container. It will keep in the refrigerator for up to 3 days. The texture may soften slightly, but it stays delicious. Freezing is not recommended, as it can break down the fluffiness.

Frequently Asked Questions

How long does this fluff last in the fridge?

Up to 3 days if kept in an airtight container. It tends to soften a bit over time, but the flavor stays on point.

Can I make this ahead of time?

Absolutely. It’s a great make-ahead dessert. Just prepare it the night before and keep it chilled until ready to serve.

Can I use natural peanut butter?

You can, but be cautious. Natural peanut butter tends to separate and may make the fluff less stable. Use a well-stirred or no-stir variety if opting for natural.

What can I serve this with?

Aside from serving in bowls, try using it as a dip for Nilla wafers, graham crackers, or apple slices. It’s great for dessert bars or potlucks.

Can I substitute the whipped topping with homemade whipped cream?

Yes, but the texture may vary slightly. Whipped topping holds up longer, especially if you’re prepping in advance.

Is this gluten-free?

The fluff itself is naturally gluten-free, but double-check your brand of marshmallows, whipped topping, and Reese’s to ensure they’re certified gluten-free.
