Ingredients for Reese’s Peanut Butter Fluff

Core Ingredients

Here’s what you’ll need to make this creamy creation:

1½ cups mini marshmallows – These add a soft, pillowy texture and a bit of chew.
1 cup creamy peanut butter – Stick with the classic creamy kind for the smoothest finish.
1 cup powdered sugar – Gives sweetness and structure.
1 (8 oz) package cream cheese, softened – This is your base, giving the fluff its rich, tangy balance.
1 (8 oz) container Cool Whip, thawed – For that signature light, fluffy texture.
1 cup chopped Reese’s Peanut Butter Cups – The star mix-in, adding bites of chocolatey peanut butter goodness.
½ cup Reese’s Pieces (optional) – These add a little crunch and color, totally optional but highly recommended.

Substitutions and Tips

Want to tweak the recipe to fit your pantry or preferences? No problem.

Swap the Cool Whip with homemade whipped cream if you prefer a less processed option—just make sure it’s whipped to stiff peaks for stability.
Lighten it up a bit with reduced-fat cream cheese and peanut butter, though the full-fat versions give the creamiest texture.
No Reese’s Pieces on hand? Mini chocolate chips or chopped peanuts can fill in for crunch.
Make it nut-free by using sunflower seed butter and skipping the Reese’s mix-ins. It won’t be quite the same, but it’ll still be delicious.

This recipe is super forgiving and perfect for adjusting based on what you’ve got. As long as you keep the creamy base intact, the add-ins are where you can have fun.

Best Peanut Butter for Reese’s Fluff

Let’s be honest—peanut butter can make or break this recipe. For the smoothest, fluffiest texture, stick with regular creamy peanut butter like Jif or Skippy. Natural peanut butters that separate tend to be too oily and can throw off the consistency. You want something stable and smooth, with just the right amount of salt to balance out the sweetness.

If you’re using a natural-style peanut butter, make sure it’s fully stirred and smooth before adding it in—but even then, you might find the fluff doesn’t hold together quite as well.

Kitchen Tools You’ll Need

Must-Have Tools

Don’t worry—you won’t need anything fancy to make this recipe happen. Here’s what you really need:

Large mixing bowl – Big enough to fold everything together without making a mess.
Electric hand mixer or stand mixer – To get your peanut butter and cream cheese super creamy.
Spatula – Essential for gently folding in the Cool Whip and mix-ins.

Nice-to-Have Tools

If you’ve got them, these extras will make things even easier:

Cookie scoop or ice cream scoop – Perfect for serving fluff into individual dessert cups.
Decorative serving bowl – Makes this look party-ready in seconds.
Plastic wrap or a lid – For covering the bowl while it chills in the fridge.

How to Make Reese’s Peanut Butter Fluff

This is one of those recipes that comes together so easily, it’s almost hard to believe how good it tastes. We’re talking rich, creamy, fluffy dessert magic—and all without turning on the oven. Whether you’re whipping this up for a party or just because the craving hit, you’ll have it mixed, chilled, and ready to enjoy in no time. Let’s walk through it together.

Step 1: Beat the Cream Cheese and Peanut Butter

Start with softened cream cheese—it should be at room temperature so it blends smoothly. Add your peanut butter to the bowl and use an electric mixer to beat them together until the mixture is light, creamy, and completely combined.

Tip: If your peanut butter has been sitting in a cold pantry, give it a quick 10-second zap in the microwave to loosen it up. You want everything blending as evenly as possible.

Step 2: Add the Powdered Sugar

Once your base is creamy, it’s time to sweeten things up. Add the powdered sugar and beat again until it’s fully incorporated. The mixture will thicken slightly, which is exactly what you want—it helps form that irresistible fluff texture later.

Step 3: Fold in the Cool Whip

Here’s where the magic happens. Grab a spatula and gently fold the Cool Whip into your mixture. Don’t stir aggressively or you’ll lose the airy texture you’re going for. Folding keeps everything light and fluffy, just the way it should be.

Tip: If you’re using homemade whipped cream instead of Cool Whip, make sure it’s whipped to stiff peaks for the best results.

Step 4: Stir in the Marshmallows and Reese’s

Now it’s time for the fun stuff. Fold in the mini marshmallows, chopped Reese’s Cups, and Reese’s Pieces (if you’re using them). Be gentle here too—you want every bite to have that perfect mix of creamy and crunchy.

Variation: If you want an extra burst of chocolate, toss in a handful of mini chocolate chips or drizzle in a little chocolate syrup.

Step 5: Chill and Serve

Spoon the fluff into a serving bowl or portion it into individual dessert cups. Cover it and refrigerate for at least an hour. This gives all the flavors time to come together and lets the texture set just right.

Serving idea: Lay out a tray with graham crackers, pretzels, and apple slices so guests can dip away. Or grab a spoon—no one’s judging.

Tips for Success

This recipe is simple, but a few small things can take it from great to unforgettable. Here’s what to keep in mind:

Soften the cream cheese fully before mixing. Cold cream cheese won’t blend as smoothly and could leave little lumps.
Don’t overmix after adding the Cool Whip. A gentle fold keeps the texture airy.
Use a cold bowl when folding in the Cool Whip, especially if your kitchen is warm. It helps everything stay fluffy.
Chop your Reese’s Cups small so you get a little bit in every bite without overpowering the texture.
Taste before chilling. Want it sweeter? Add a tablespoon or two more powdered sugar before popping it into the fridge.

How to Store Reese’s Peanut Butter Fluff

In the Refrigerator

Reese’s Fluff stores beautifully in the fridge. Just transfer it to an airtight container and keep it chilled for up to three days. In fact, it often tastes even better the next day as the flavors settle in together.

Freezing Tips

Freezing isn’t recommended for this dessert. Because of the whipped topping and cream cheese, the texture changes when thawed—it becomes watery and a bit separated. It’s best enjoyed fresh or within a few days from the fridge.

Frequently Asked Questions

Can I make Reese’s Peanut Butter Fluff ahead of time?

Absolutely. In fact, it’s a great make-ahead dessert. Mix it up the night before and let it chill overnight. Just give it a quick stir before serving.

Can I freeze leftovers?

Technically, you could, but I wouldn’t recommend it. Freezing tends to mess with the creamy texture, and that fluffiness is what makes this dessert shine.

Can I use chunky peanut butter?

Sure, you can—but it’ll change the texture. If you love a little crunch, go for it. Just know the final result won’t be quite as smooth and fluffy.

What should I serve it with?

It’s delicious with graham crackers, pretzels, or even fresh fruit like apple slices. Vanilla wafers are a classic too. Or just enjoy it by the spoonful.
