Ingredients

This recipe uses just a handful of simple ingredients, most of which you probably already have in your kitchen.

Cottage Cheese

Use full-fat cottage cheese for the best results. It blends more smoothly and creates a richer, creamier mousse. Low-fat versions will work, but the texture may be slightly thinner and less luxurious.

Peanut Butter

Choose natural peanut butter with no added sugar or oils. It provides healthy fats, depth of flavor, and that classic nutty richness that makes this mousse irresistible.

Sweetener

You can use whatever sweetener fits your lifestyle:

• Allulose, erythritol, or monk fruit for a sugar-free option
• Honey or maple syrup for a natural sweetener

Liquid sweeteners blend more easily, but powdered options work just as well—just adjust to taste.

Vanilla Extract

A small amount of vanilla extract enhances the sweetness and balances the tanginess of the cottage cheese. Don’t skip it—it makes a big difference.

Milk or Heavy Cream (Optional)

If the mousse feels too thick after blending, add a splash of milk or heavy cream. Milk keeps it lighter, while cream makes it extra rich and dessert-like.

Optional Pinch of Salt

A tiny pinch of salt helps enhance the peanut butter flavor and balance the sweetness.

Instructions

This mousse comes together in just a few easy steps.

Step 1: Add Ingredients to Blender

Place the cottage cheese, peanut butter, sweetener, vanilla extract, and optional pinch of salt into a high-speed blender or food processor.

Step 2: Blend Until Smooth

Blend on high for 30 to 60 seconds, stopping once or twice to scrape down the sides. The goal is a completely smooth, fluffy, mousse-like consistency with no visible curds.

If the mixture looks too thick, add 1–2 tablespoons of milk or heavy cream and blend again until smooth.

Step 3: Chill (Optional but Recommended)

Transfer the mousse to a bowl or individual jars and refrigerate for 15–20 minutes. This allows the texture to set slightly and the flavors to develop.

Step 4: Serve and Enjoy

Spoon into bowls or jars and add your favorite toppings. Serve chilled for the best texture and flavor.

Variations

One of the best things about this recipe is how easy it is to customize.

Chocolate Peanut Butter Mousse

Add 1–2 teaspoons of unsweetened cocoa powder or a scoop of chocolate protein powder for a rich chocolate-peanut flavor.

Extra Crunch

Stir in chopped peanuts, almonds, or sugar-free chocolate chips after blending for added texture.

High-Protein Version

Blend in a scoop of vanilla or peanut butter protein powder for an extra protein boost—perfect for post-workout snacks.

Cheesecake-Style Cups

Layer the mousse with crushed low-carb cookies or almond flour crust in small jars. Chill for a few hours for a no-bake cheesecake vibe.

Banana Peanut Butter Mousse

Add a few slices of ripe banana before blending for natural sweetness and a smoothie-like flavor (not low-carb).

Dairy-Free Twist

Use dairy-free cottage cheese alternatives and plant-based milk for a lactose-free version (texture may vary slightly).

FAQ

Does cottage cheese really work in dessert?

Yes! Once blended, cottage cheese loses its curdy texture completely. It becomes smooth, creamy, and neutral-tasting, making it perfect for sweet recipes.

Can I make this without a high-speed blender?

A food processor works well, though you may need to blend a bit longer. An immersion blender can work too, but the texture may be slightly less smooth.

How long does it last in the fridge?

Stored in an airtight container, the mousse stays fresh for up to 4 days in the refrigerator.

Can I freeze it?

Freezing is not recommended. Cottage cheese tends to become watery and grainy once thawed, which affects the mousse texture.

Is this recipe keto-friendly?

Yes, as long as you use a low-carb sweetener like monk fruit, erythritol, or allulose.

Can I eat this for breakfast?

Absolutely. With its high protein content and healthy fats, it makes a filling and satisfying breakfast or snack.

What toppings work best?

Dark chocolate drizzle, chopped nuts, berries, shredded coconut, or sugar-free chocolate chips all pair beautifully with this mousse.
