Keto Peanut Butter Mousse | Keto Desserts
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.

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!)

I looked it, but came out at little gritty. I used swerve confectioners. Did I not mix long enough?
If you used the natural peanut butter it does have a bit of a gritty texture compared to regular peanut butter.
I love it!
Glad you enjoyed, Linda!
I have made this several times, my husband loves peanut butter, and now I want to try the lemon berry version. This is a delightful treat all year long. Thank you for your wonderful recipes.
Glad you enjoyed!
Was there ever a more satisfying peanut butter dessert? Delicious! I used Greenwise natural peanut butter and Swerve confectioner’s sugar. I also added ONE DROP of “salted caramel extract”. The stuff is pretty powerful but added a wonderful “caramel-y” taste. Next time I make it, and there will be a next time, I will double the recipe, make a keto almond flour crust, and turn it into a pie. Sprinkled with my Lily’s sugarless chocolate chips, it’s awesome. Really.
Yum! That sounds delish!! I’m so glad you loved it. Let me know how it turns out as a pie.
AMAZING! This is so good especially if you have a sweet tooth. Perfect dessert on Keto.
Jennylee, so glad you liked it!!
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.
I’m glad you enjoyed it!
Easy to make and so delicious! Thanks for another fantastic recipe Kasey.
What jars did you use in the pics and the video? They’re cute and are the perfect size.
So delish. I used PB2 it was great. Added a little less sweetener. I love it-hits the spot
Yay! So glad you love it.
So easy to make & so very delicious! Will definitely be making this again & again!!!
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!
I”n not sure. I don’t use an app to track macros.
So delicious! I love this and it satisfies my sweet tooth!
I’m glad you love it!
I checked to see if you might have a mocha or coffee flavored fluff bombs?
I don’t. Sorry.
Couldn’t you use instant coffee to Achieve a mocha flavor
I know the recipe says it has 6 servings but what amount or size are each of the servings?
I just divide it evenly into six cups.
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
Can you use swerve granulated sugar instead of swerve confection
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.
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?
You aren’t missing anything. It is hard to tell in pictures the size of the containers as they are very small.
