You haven’t lived until you’ve experienced my peanut butter mousse recipe. It’s thick yet airy, creamy yet rich, and loaded with sweet and subtly salty peanut butter flavor. 

The best part? You don’t need a laundry list of ingredients or multiple kitchen gadgets to make the magic happen.

Why I love this recipe

  • 4 ingredients. Count them yourself- and they are basic pantry staples.  
  • No eggs needed. Unlike most mousse recipes, mine doesn’t require eggs, yet it’s every bit as light and creamy. 
  • Easy to make ahead. I’ve made this mousse up to three days in advance, and you’d never be able to tell.
  • Fun to customize. Serve with crunchy toppings, use it as a filling, or make parfaits. This recipe is what YOU make of it.

Ingredients needed

  • Peanut butter. Make sure to use smooth, creamy peanut butter, as the crunchy or natural kind can be hard to whip. 
  • Cream cheese. Softened to room temperature. I prefer the texture of full-fat cream cheese, but you can use the low-fat variety if preferred. 
  • Powdered sugar. Also known as confectioners’ sugar, this will help thicken the mousse. 
  • Vanilla extract. Optional, but adds a lovely touch of vanilla. 
  • Heavy cream. Use either standard or heavy whipping cream. I’ve tested both and it was almost identical.

Step 2- Fold. Working in batches, gently fold the whipped cream into the peanut butter mixture until combined. 

Step 3- Pipe. Transfer the mousse into a piping bag with a swirly tip. Pipe into jars and serve.

Arman’s recipe tips

  • For a thicker mousse, refrigerate the mixture for at least 30 minutes.
  • Serve with toppings, like crushed peanuts or chocolate shavings. 
  • Swap the peanut butter for other nut butter (like almond butter or cashew butter), or use tahini for a nut-free recipe. 
  • Turn it into a parfait. Layer the mousse between sheets of cookie crumbs, chopped nuts, and plain whipped cream. 
  • Use it as filling in chocolate peanut butter cake or to frost almond flour cupcakes!

Storage instructions

To store: The mousse should always be stored in the refrigerator, covered. It will keep well for up to 2 weeks. 

To freeze: Cover the mousse completely and store them in the freezer, for up to 6 months. Thaw in the refrigerator overnight before serving.

    I know this recipe is very high calorie, but I am in bulking phase and need to gain weight. So this recipe could be my go-to!

  2. 5 stars
    This came out great! I used this mousse recipe to make a peanut butter cup mug, filling the base with the mousse and topping with a thick layer of chocolate ganash.

    One thing I did notice though, the ingredient lists only 4 items, but the first step is “In a large mixing bowl, beat together the peanut butter, cream cheese, powdered sugar, and vanilla extract”; vanilla extract isn’t listed in the measurements. How much vanilla is recommended for each cup of the other four ingredients?

      1. 5 stars
        I made this with tahini and maple extract instead of peanut butter and vanilla. Great texture, very quick to make and delicious!

    The best so far!!!!! I used plain Greek yogurt. I am new to low car, no sugar, low fat anything. I am extremely hard to please. This was delicious!!!!!!!!

    Being Diabetic, I’m always looking for low-carb, sugar free Recipes. These are wonderful!!
    My family loves the Mousse. ♥️

  5. Hi. This looks delicious. Love that it’s low carb but it is very high fat. Can you tell me how much you suggest eating if you are trying to maintain weight? Thank you

    So good!! So I accidently just mixed everything in a bowl together(I can’t read lol) and it still turned out wonderful after a few mins of heavy stirring. Smooth and delicious. I added some dark chocolate chips on top and sugar free whip.

  8. This recipe is delicious. I add unsweetened baking chocolate because I love chocolate. A hit for sure!!!

  9. 5 stars
    I’m not a big PB fan but I was looking for a low sugar option for some PB loving guests — this recipe was a big hit! Topped with a few Lily’s chocolate nibs for a little extra sweetness. Thanks for this one! Can’t wait to try it again another time 🙂

    This came out great. I’m putting it on top of keto brownies. I didn’t have powdered swerve so i just put granulated in my ninja and turned it into powdered. Saved buying a whole bag for right now.

    So very easy to make and devilishly satisfying. I’ve made this multiple times and it never gets old.

  12. 5 stars
    This was unbelievably delicious!
    I’m trying to cut down sugar and cards. With this being one of my favorite desert dips, I thought I’d love to try this recipe but I won’t set my standards high. Boy was I wrong! New healthy favorite for the whole family! No bad aftertaste and I can’t tell it’s not made any differently! Thank you!!

  13. This recipe is incredible! It’s perfectly sweet and satisfies a sweet too for sure! I added a little sugar free vanilla syrup to the whip! So good! Definitely going to be a keto staple in my house!

  14. I’ve made this several times. I layer it with sugar free chocolate syrup and top with sugar free white and chocolate chips 🙂

  15. 5 stars
    Super *AMAZING* recipe! Thank you so much for taking the time to leave it here for all of us.
    I made a few minor tweaks (to my taste): added extra vanilla, about a third of a cup less PB, a dash of cinnamon and only a quarter cup of powdered sugar.

  16. You could try rice malt syrup, is it Leto..not sure. But I have switched out sugar for that before. It is thick like golden syrup, and can be measured the same as normal, just use equivalent measuring cup

  17. Just made a smaller batch of this as I was craving something sweet. Hit the spot – delicious.

    Thank you!

  18. Do you think this would work as a cake frosting? I want to make something special for my husband for valentines and the combination of peanut butter with chocolate is his favorite.

    1. Hi April- I think it will be too thin or thin out if left as a frosting unfortunately. You could try it on a chilled cake or pudding though 🙂

    Just made this and it’s delicious!
    It pretty much tastes like peanut butter cheesecake. Easy to whip up

  20. This is excellent! Has very peanutty flavor and great mousse texture. Be sure to powder your sugar or will be gritty! Husb loves it!!

      It’s good but I had to decrease the heavy cream by half and the powdered sugar by half due to my diabetes and I still couldn’t have a normal portion
