Light and Creamy Protein Fluff Dessert Recipe

This simple protein fluff recipe comes together quickly to make a sweet, fluffy dessert that’s high in protein and sugar-free.

This high-protein fluff is made from cottage cheese, peanut butter, and a sweetener, then whipped in a food processor into a light, mousse-like pudding with a distinct peanut butter flavor.

How To Make Protein Fluff

For this recipe you’ll need cottage cheese (full-fat or low-fat), peanut butter, vanilla extract (optional), and a sweetener of your choice. Monk fruit is a good zero-calorie option, but erythritol, stevia, allulose, honey, or maple syrup also work depending on your diet.

Add the cottage cheese, peanut butter, vanilla, and sweetener to a food processor or high-speed blender. Blend on high until the mixture is completely smooth and creamy, about 30–60 seconds depending on your appliance. Transfer the fluff to a storage container and refrigerate until chilled.

Serve plain or top with fresh fruit, chopped nuts, seeds, or a few chocolate chips.

Substitutions & Variations

• Dairy-Free Option: Substitute dairy-free Greek-style yogurt for the cottage cheese.
• Nut-Free Alternative: Use sunflower seed butter or tahini in place of peanut butter.
• Sweetener Options: Use erythritol, stevia, allulose, or for non-keto choices, honey or maple syrup.
• Flavor Variations: Stir in a tablespoon of cocoa powder for chocolate fluff or add cinnamon for a warm spice note.

Protein Fluff FAQ

What does protein fluff taste like?

It tastes creamy and peanut butter-forward, with a light, airy texture similar to mousse or pudding.

Can I use Greek yogurt instead of cottage cheese?

Yes. Greek yogurt is a great substitute and will give the fluff a slightly tangier flavor.

Is this fluff good for meal prep?

Yes. Store it in an airtight container in the refrigerator for up to 4 days. Freezing is not recommended because it will change the texture.

How can I make it even fluffier?

Blend a bit longer for extra air, or fold in a small amount of whipped cream or whipped egg whites for a lighter consistency.

Can I add protein powder?

Yes. Stir in a scoop of vanilla or chocolate protein powder if you want more protein. You may need to add a little extra liquid to reach the desired consistency.
