Ingredients

(Here's a tip: Check out the full list of ingredients and measurements in the recipe card below.)

1 cup cottage cheese (full-fat for the creamiest texture)
¼ cup peanut butter (natural, no sugar added)
2 tablespoons sweetener (like allulose, monk fruit, or a sugar-free syrup)
1 teaspoon vanilla extract
¼ teaspoon salt (optional)
1–2 tablespoons milk or heavy cream (optional, for consistency)

Optional Toppings:

2 oz dark chocolate chips
1 teaspoon coconut oil
Chopped peanuts for garnish

Directions

I add the cottage cheese, peanut butter, sweetener, vanilla, and salt to a blender or food processor.
I blend for about 30–60 seconds, or until the texture is completely smooth and creamy.
If the mousse seems too thick, I add a little milk or cream and blend again until it’s just right.
I transfer the mousse to a bowl and chill it for 15–20 minutes in the fridge to let the flavors meld and the texture firm up.
Before serving, I top it with melted chocolate and a sprinkle of chopped peanuts for crunch.

Servings and Timing

This recipe makes 2 servings. It takes about 5 minutes to prepare, plus 15–20 minutes of optional chilling time. In total, I can have this ready to eat in under 30 minutes.

Variations

Chocolate Peanut Butter Mousse: I add a teaspoon or two of cocoa powder for a rich chocolatey twist.
Crunchy Style: I stir in some crushed peanuts or chopped almonds after blending for a fun texture.
Extra Protein: I mix in a scoop of protein powder to boost the nutrition.
Mini Mousse Cups: I layer the mousse with crushed keto cookies or chopped nuts in small jars for a dessert-style presentation.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days.
I don’t recommend freezing this mousse, as the texture can become watery once thawed.
It’s great for meal prep—I divide it into jars for a grab-and-go treat throughout the week.

FAQs

What kind of cottage cheese should I use?

I always use full-fat cottage cheese because it gives the smoothest and richest result when blended.

Can I use something other than peanut butter?

Yes, I can swap in almond butter, cashew butter, or even sunflower seed butter if I need a nut-free option.

Do I have to chill the mousse before eating?

Not at all—I can eat it right away. But I find that a short chill in the fridge makes it thicker and more mousse-like.

Can I make this recipe ahead of time?

Definitely. I like to make a batch ahead and portion it out for a few days’ worth of snacks or desserts.

How do I adjust the sweetness?

I just taste it after blending and add more sweetener if I want. It’s easy to customize depending on my preference and the type of sweetener I’m using.

Conclusion

This Cottage Cheese Peanut Butter Mousse is a fast, delicious, and protein-packed option when I want something sweet but still nourishing. With simple ingredients and minimal prep, it’s one of those recipes I turn to again and again. Whether I top it with chocolate, nuts, or enjoy it plain, it always hits the spot.
