Keto Peanut Butter Mousse
When it comes to super easy keto desserts, my favorite recipes to make are chocolate mousse, custard, and this easy keto peanut butter mousse.
Growing up, my mom’s favorite desserts to make were rarely of the baked variety. Unless it was a family member’s birthday or a bake sale, she stuck to no cook desserts. This suited me fine, as I love any and all kinds of desserts. Her favorite things to make were usually a pudding or a no bake cheesecake, but my all time favorite was her peanut butter mousse.
My mom first started making her peanut butter mousse after her work colleague’s wedding. Her colleague was originally from America and introduced her to the wonders of peanut butter. Instead of a wedding cake, they served a mini dessert sampler, which included a peanut butter mousse. She acquired the recipe and added it to her repertoire. When I first moved out of home, it was one of the very first recipes of hers I ever made and was so easy to adapt to be keto!
I’ve been meaning to share a keto peanut butter mousse recipe for quite some time. It’s been my go-to dessert whenever I don’t feel like turning on the oven. I love how it needs just 4 ingredients and takes seconds to prepare- the hard part is waiting for it to chill!
No eggs and no sugar are needed, but you’d never tell. The texture is smooth, airy, and extra creamy. It’s sweet and full of peanut butter flavor.
I had some friends over for dinner the other night and served them this mousse for dessert and NO ONE believed me when I said that it was low carb- They thought it had to be full of sugar!
Ingredients to make a keto peanut butter mousse
Here are the ingredients you’ll need to make this mousse. It’s best for all your ingredients to be at room temperature, for the ultimate smooth texture.
- Peanut butter– Smooth and creamy peanut butter, with no added sugar. Avoid using crunchy or the natural kind, as it will be harder to whip.
- Cream cheese– Full fat and softened cream cheese. You can also use dairy free cream cheese.
- Powdered sweetener– Don’t waste your money buying expensive packaged varieties, make your own homemade sugar free powdered sugar.
- Vanilla extract– Optional, but adds a lovely touch of vanilla.
- Heavy cream– Either standard or heavy whipping cream can be used.
How do you make a peanut butter mousse?
Start by adding the peanut butter, cream cheese, powdered sweetener, and vanilla extract, if using it, into a large mixing bowl. Using a hand or stick mixer, beat together until combined. Next, add the heavy cream into a separate bowl and beat until stiff peaks form. Gently beat 1/4 of the whipped cream into the peanut butter mixture. Fold through another 1/2 of it, before adding the remaining cream until combined.
Now, transfer the peanut butter mousse into a piping bag with a star tip attached. Pipe the mousse into serving glasses or mason jars and refrigerate for 30 minutes, to firm up.
Tips to make the best low carb peanut butter mousse
- You can prepare this mousse up to 3 days in advance. Omit any extra toppings (e.g. crushed peanuts or whipped cream) until you are ready to serve it.
- Don’t add all the whipped cream at once- Do it in batches so it keeps the whipped peanut butter airy and light.
- If you’d like to make this peanut free, swap out the peanut butter for either smooth almond butter or tahini.
Storing and freezing the peanut butter mousse
- 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.

Could you use liquid stevia in place of the powdered sugar?

Smooth and tasty.easy to make fir 1p when you get a craving. Yum
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.
Can’t wait to try it!
It’s so delicious and easy to prepare, such an amazing taste! Thank you, Arman 👍
Delicious!! Perfect recipe for keto but truly for anyone!
Give it a A+
I made this. Delicious!!! Everyone love it!!!!
This recipe is delicious. I add unsweetened baking chocolate because I love chocolate. A hit for sure!!!
Awesome
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.
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!!
Delish!
I don’t have a food processor. Can I use a regular granulated sweetener?
How many ounces in one batch of 8 servings?
No idea, we don’t weigh it 🙂
I love the peanut butter moose it is so good
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!
Delicious! Thank you!
Can I use regular powdered sugar and neufchatel cheese in this?
Absolutely!
Made a mistake a threw all ingredients in a bowl at once and beat it. Still turned turned out great
Recommend adding 1/2 tsp salt and 1/8 tsp of almond extract.
I’ve made this several times. I layer it with sugar free chocolate syrup and top with sugar free white and chocolate chips 🙂
I tried this being skeptical because it sounded like a lot of powdered sugar. It was so amazing and creamy.
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.
Is it 1 cup of cream cheese (8 oz volume) or an 8-oz block (weight)?
Yes it is 🙂
Can I use the powdered pb?
Not that I’ve tried
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
Anything I can use to replace the artificial sweetener?
Can’t stand that stuff…yuck
Standard sugar.
Just made a smaller batch of this as I was craving something sweet. Hit the spot – delicious.
Thank you!
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.
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 🙂
This stuff is amazing, and addictive! We can’t stop eating it.😘
Do you think coconut cream would work for the heavy cream to make it vegan?
I haven’t tried 🙂
This is excellent! Has very peanutty flavor and great mousse texture. Be sure to powder your sugar or will be gritty! Husb loves it!!
OMGoodness! DELICIOUS! I couldn’t stop licking the bowl!
So good! Freeze then thaw for 30 mins = ice cream!
this the best keto dessert recipe ever!!!!!
Love it!
5 ingredients lol, very good
One is clearly optional 🙂 Enjoy this 4 ingredient dessert!
OMG! Delicious!
Thank you, Trisha!
