This deliciously easy Keto Peanut Butter Mousse recipe will make you forget you are following a low carb diet. It’s one of my favorite keto desserts to make! It is the perfect light and fluffy alternative to those dense fat bombs! At just 2g net carbs per serving and 5 simple ingredients, it’s impossible to resist!
How To Make Low Carb Peanut Butter Mousse
It’s hard to believe that something so good is low in carbs, contains healthy fats, AND taste amazing! Believe it or not, this fluffy mousse takes just a few minutes to whip up, so you don’t need to wait long to enjoy it. It is so rich in flavor yet super-light; you’ll be satisfied with just a few bites! I love it, even more, when I top it with Lily’s chocolate chips. Chocolate and peanut butter, how can you go wrong? So if you feel like indulging or have a craving for something sweet, this is it!
Ingredients:
- Heavy Whipping Cream: This is the base of the mousse and is what creates the fluffy and airy result you want out of a mousse.
- Cream Cheese: Cream cheese gives your keto mousse a nice, creamy consistency while adding more fat to the dessert.
- Peanut Butter: Peanut butter adds healthy fat as well as flavor to your mousse. My favorite natural peanut butter to use in this mousse is Smucker’s Natural.
- Swerve Confectioners Sugar: This is a great sugar-free keto-friendly way to add sweetness to your mousse. You can also use Lakanto Monkfruit Powdered at the same measurement.
- Vanilla Extract: Vanilla adds a delicious flavor that goes a long way in this recipe.
Step by Step Pictures:
Step 1: Measure out your ingredients and allow you cream cheese to come to room temperature to allow it to mix easily.
Step 2: In a medium-sized bowl, beat heavy whipping cream until it almost doubles in size. Make sure your bowl and beaters are dry before adding the heavy whipping cream and beating to stiff peaks. It’s also important that the heavy whipping cream is cold.
My favorite natural peanut butter to use in this mousse is Smucker’s Natural Crunchy. I love the extra texture the crunch adds.
Step 3: In a separate bowl, add the softened cream cheese, natural peanut butter, Swerve Confectioners (or Lakanto Monkfruit Powdered), and vanilla then beat with a mixer until the fluff is smooth and creamy.
Step 4: Fold in your whipped cream gently. I like to use a rubber spatula for this. You want to keep as much air in the mousse as possible.
Step 5: You can dish out servings right out of the bowl or use a piping bag to pipe it into small glass jars if you want to be fancy. If you do not have a piping bag, use a plastic baggie, and snip off the corner!
Isn’t this presentation gorgeous! It would be a great way to serve at a dinner party. You can fill your jars ahead of time and keep them in the fridge. No one would even know it’s keto!
How to store your mousse
Store in the fridge in an airtight container or individually in jars for up to a week. You can also freeze it as well, allowing it to last for about 6-8 weeks. We’ve never had any left-over at our house to freeze; it’s THAT Good.
Allergic to peanut butter?
You can replace the peanut butter with one of these keto-friendly substitutes:
- Almond butter
- Sunflower seed butter
- Coconut butter
- Macadamia nut butter
- Sesame seed butter (tahini)
- Cashew butter
- Pecan butter
Other sweetener options:
Here are other keto sweeteners you can use. Just make sure to use powdered, aka confectioners sugar, as opposed to granulated.
Other than Swerve Confectioners, you can use Lakanto Monk Fruit Powdered, since both have a 1:1 ratio. I have recently started using Besti Monk Fruit with Allulose sweeteners and have been very impressed. Out of all the sweeteners that I have tried, it has the least bitter aftertaste to me.
Total net carbs per serving
This peanut butter mousse has just 2g of net carbs per serving. This serving size is based on six equal-sized servings.

Recipe for keto mousse with Peanut Butter:
Keto Peanut Butter Mousse
Ingredients
- ½ cup Heavy Whipping Cream
- 4 oz Cream Cheese (softened)
- 2 ½ tbsp Natural Peanut Butter (I use Smucker's)
- 5 tbsp Swerve Confectioners
- ½ tsp vanilla extract
- ½ square unsweetened chocolate or Lily's Chocolate Chips (optional)
Instructions
- In a medium-sized bowl, beat heavy whipping cream until it almost doubles in size. Set aside.
- In a separate bowl, add the softened cream cheese, natural peanut butter, Swerve Confectioners (or Monkfruit Powdered), and vanilla then beat with a mixer until the peanut butter fluff is smooth and creamy.
- Add the whipped cream to your peanut butter mixture and fold it in gently using a rubber spatula. Try to keep as much air in the mousse as possible. Mix until combined.
- Grate unsweetened chocolate shavings on top or add Lily's Chocolate Chips over top. (This is optional, but it really makes it tastes so amazing!)
- Serve right away or refrigerate overnight. (I think it is best kept in the refrigerator overnight and served the next day!)

Debra B. Shelestak says
It’s delicious and so simple to whip up. It does not make 6 cups that look like the one in the picture. It made one. But listen, this is just really good. The one cup has lasted me a whole week. It’s very rich and satisfying with just a couple bites.
Mary Trenum says
I’m glad you enjoyed it!
Keli says
Easy to make and so delicious! Thanks for another fantastic recipe Kasey.
Kerri says
What jars did you use in the pics and the video? They’re cute and are the perfect size.
Wendy says
So delish. I used PB2 it was great. Added a little less sweetener. I love it-hits the spot
.Kasey says
Yay! So glad you love it.
Donna says
So easy to make & so very delicious! Will definitely be making this again & again!!!
Sylvanna Cienfuegos says
So decadent! I love it! Thank you for sharing! Just one question. Im trying to put this nutritional info into my carb manager app but im not sure how much is 1 serving in grams or ounces. I know its 6 servings in 1 cup…which is what this recipe yields. But how would you say 1/6 in ounces or grams is? Appriciate it!
Kasey says
I”n not sure. I don’t use an app to track macros.
Michelle Harper says
So delicious! I love this and it satisfies my sweet tooth!
.Kasey says
I’m glad you love it!
Diane says
I checked to see if you might have a mocha or coffee flavored fluff bombs?
.Kasey says
I don’t. Sorry.
Deb says
Couldn’t you use instant coffee to Achieve a mocha flavor
Danielle Parris says
I know the recipe says it has 6 servings but what amount or size are each of the servings?
.Kasey says
I just divide it evenly into six cups.
Teresa Colwell says
What I do is weigh the finished product and then divide that by number of servings to find out what each individual serving should weigh
Michelle says
Can you use swerve granulated sugar instead of swerve confection
.Kasey says
You can grind a classic sugar free sweetener into powdered in a blender. For this recipe, I don’t think that granular would work as it may be a bit grainy.
Kathryn says
Very good and super easy. I don’t understand how you get six servings out of it that look the way this website portrays.. I got four servings and was lucky to get 2 1/2 ounces into each. Which was nothing compared to what the pictures look like. I followed directions exactly. Am I missing something?
Kasey says
You aren’t missing anything. It is hard to tell in pictures the size of the containers as they are very small.
Phyllis says
Made this tonight but used almond butter. It was so good. The chocolate chips definitely make this even better.
.Kasey says
I love adding chocolate chips to desserts! Glad you enjoyed this.
Laura says
We have a winner! These were so delicious! I used granulated Stevia instead of confectioners. I just mixed for a few minutes, then let it sit for a bit for the Stevia to desolve better, then mixed a bit more before adding the already whipped heavy cream.
I doubled the recipe and got 12 regular-sized silicone cupcake liners full. If I had doubled your 5 tbsp of confectioners, it would have been WAY too sweet. I stuck with just 5 tbsp of granulated Stevia, and it was perfect.
I will definitely be making these again!
.Kasey says
Awesome! Glad you enjoyed them!
Ronda Ramsey says
Omg I’m in love with this recipe
.Kasey says
That’s awesome! Glad you love it.
Diona Green says
Can these be frozen for bite size snacks instead of filling little cups?
.Kasey says
I’ve never tried to freeze them bite size before but I don’t see why it wouldn’t work. Worth a try.
Sue says
Can I use PB Fit powder to make these? I have so much of that and no recipes:(
Thanks
Kasey says
I have only made this recipe as is so I’m not sure.
Leslie Haller says
Peanut Butter Heaven! Thanks so much for an awesome delicious recipe! I froze some of it and it was like ice cream,yum!
.Kasey says
Wonderful! Glad you loved it!
Lisa says
Looks awesome!
Kerri says
What jars did you use in the pics and the video? I know you said that they are small, but they’re cute and I would love to buy them.
