3-Ingredient Peanut Butter Mousse

This 3-Ingredient Peanut Butter Mousse is a creamy, high-protein snack made with cottage cheese, peanut butter, and maple syrup. Ready in just 5 minutes, it’s an easy make-ahead recipe that’s perfect for a satisfying snack or lighter dessert.

Snacks are crucial.

They bridge the gap from one meal to the next. It would be tough to go from lunch to dinner (and often breakfast to lunch!) without an afternoon snack.

They’re also energizing. Because calories provide energy, snacks are the perfect vehicle to give your body much needed energy mid-afternoon or mid-morning.

That said, it can be hard to figure out what to eat for a snack.

While I love the classics like hummus and crackers, smoothies, and string cheese…. sometimes I need a little something more.

Enter: this Peanut Butter Mousse. It’s made with just 3 simple ingredients and makes the most delectable snack.

I love that you can make it ahead of time, too, to have snacks on hand for a few days. Having an afternoon snack to look forward to is such a small glimmer during a busy day!

I’ve been topping mine with some chocolate chips and fresh raspberries lately. It’s the perfect combination of protein, fiber, and deliciousness to keep you feeling full and satisfied.

Is this mousse the same thing as a dessert mousse? Absolutely not. And please don’t try to make it a replacement!

There’s room for both in a healthy diet and healthy relationship with food.

Enjoy this high protein, 3-ingredient peanut butter mousse any time you want a delicious snack that’ll energize you and give your body some nutrients too.

If You Love This Peanut Butter Mousse, Try These Peanut Butter Recipes

Ingredients You’ll Need

  • Cottage cheese: Make sure to use full-fat cottage cheese. If the cottage cheese curds have separated from the liquid at all, do NOT add the liquid. Less liquid gives you a thicker mousse.
  • Peanut butter: I used an unsweetened peanut butter in this recipe since we’re adding maple syrup to sweeten. If you only have or want to use sweetened peanut butter, no problem! You may want to decrease the maple syrup to account for the extra sweetness. Start with 1 tablespoon and taste to adjust from there.
  • Maple syrup: Want a sweeter mousse? Add an additional tablespoon of maple syrup. For a slightly less sweet mousse, only use 2 tablespoons of maple syrup.

3-Ingredient Peanut Butter Mousse Tips & Variations

  • Texture: Depending on the brand of cottage cheese you use, this mousse may come out a little thinner or thicker. For a thicker texture, try adding a teaspoon or 2 of melted coconut oil and then letting the mousse sit in the fridge for about an hour. You can also add protein powder to thicken the texture if need be, although this will affect the flavor of the mousse.
  • Variations: Make this a chocolate mousse by adding cocoa powder to the food processor. Want to make it even higher in protein? Add your favorite protein powder. The options are endless!
  • Storage: Store Peanut Butter Mousse in an airtight container in the fridge for up to 4 days.

Frequently Asked Questions

You can use full-fat Greek yogurt, but the texture and flavor will be different. Greek yogurt will give the mousse a tangier flavor and may make it slightly less thick and creamy than cottage cheese.

For the thickest mousse, use full-fat cottage cheese and avoid adding any excess liquid from the container. You can also refrigerate the mousse before serving to help it firm up. You can also a little melted coconut oil to the mixture, which will help it to thicken in the fridge.

Yes! This is a great make-ahead snack. Prepare the mousse, store it in an airtight container in the refrigerator, and enjoy it within 4 days.

Almond butter or cashew butter should work well, although the flavor and consistency will vary depending on the nut butter.

    Who knew cottage cheese could be so good?! This is a great recipe, especially if you like peanut butter.

  2. 5 stars
    This was so good – I love peanut butter and chocolate. I followed the recipe, except I did add a little bit of peanut butter powder for more pb taste. I made a coconut oil/cocoa hard shell and added a few peanuts on top. Delicious!

    I was highly highly skeptical of this recipe. I really thought there was no way this was going to taste good but I had a two day expired container of cottage cheese so decided to give it a shot. Wow it’s so incredibly delicious. So creamy, so smooth and you can’t tell at all that it’s cottage cheese. The pb to cottage cheese ration felt so small too but wow ya this is just delicious. I usually make this with Greek yogurt and pb fit but I like this more now. Topped with melted chocolate and chopped peanuts. Amazing recipe.
