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.
Total net carbs per serving

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!)

Notes
Nutrition
You can substitute sugar-free chocolate chips instead of the chocolate shavings.

can you use almond butter instead of peanut butter?
Sure! It should work just fine.
Hey Ya’ll this is a great recipe as is, but I also like to use Lily’s chocolate chips in place of the shaved chocolate and use my small cookie scoop to put on wax or parchment paper, sprinkle lightly with Truvia and freeze them for a frozen fat bomb that is the bomb!
That sounds fabulous!!!
After I made these and put the recipe into MyFitnessPal it ended up being more carbs than advertised. I got 9.9g carbs with 0.4g of fiber :/ . Protein and fat were similar. Not sure what the difference is.
MyFitnessPal is not a Keto app. It doesn’t know to subtract the sugar alcohols from Swerve. You have to subtract those manually.
What can I use to replace the cream cheese as I can’t eat it due to migraines…
I am not sure there is a substitute.
Daiya has a coconut replacement for cream cheese. I use it to make grape salad for special occasions
Perfect! Thanks for the tip!
Do you know what the equivalent of the Swerve would be in Stevia drops?
I don’t. I would just start adding and taste until it is sweet enough.
This was amazing! I am going to add in pumpkin next time. The only challenge I had was the 5 tablespoons of swerve. That seemed like WAY too much… or maybe I got the wrong Swerve? It’s 5 carbs per teaspoon…. so 5 TABLESPOONS would be a huge amount of carbs. Please let me know if I’m doing something wrong. I used 2 tablespoons and the flavor was still amazing. Thanks!!
Yay! Glad you loved it. Most people subtract the sugar alcohols from the carbs in Swerve making it 0 net carbs. Here is a recipe for pumpkin fluff.

Hi! We can’t wait to try this! Just started the Keto diet and this sounds fantastic! I was wondering if you need to use Swerve Confectioners? We have Swerve, but I don’t think it’s the confectioners. Thanks!
I haven’t tested it with regular Swerve so I can’t say from experience.
I use my Bullet smoothie maker to grind the Swerve and it makes powdered sugar out of it to use…you could also use a blender or small food processor but be careful not to breathe in the dust when you first pour it in to grind it!
Awesome!Thanks for the tip.
All you have to do is put in food processor to make into confectionary Swerve by pulsing it until it’s finer. Hope this helps. Can do the same with regular sugar to make confectionary sugar.
Love these. Have one in the morning and I’m good till lunch. Thanks ?
Yum! Sounds like a great breakfast idea.
Kasey awesome treat idea! We just made ours with regular swerve and it came out delicious but slightly gritty which is not an issue. I’m curious to ask about what would be a serving size since this recipe serves 8? Any information would be great! Thanks again it taste great!
Glad you loved it. A friend gave me this recipe. I just divided it into 8 equal sized servings. I didn’t measure it out. Thanks!
Is the whole 8 servings 2 carbs? Or just one serving is 2 carbs?
One serving is 2 carbs.
If using Lily’s chips, how much do you use? Not sure what equals 1/2 square of unsweetened baking chocolate.
You will just have to eyeball it. I don’t add much.
Hi! Would like to try this but have a couple questions- are you subtracting the ethriyol in in the swerve and also in lilys chocolate chips? Thank you!
Yes
May or may not have just eaten the whole thing!
Used Monkfruit because I’m so not a fan of Swerve. And only used half a tablespoon!!
It is truly one of my favorite sweet treats!
Loved it! For me though it was more like 2 servings! Lol, I couldn’t stop eating it, it was so good!
lol! I understand. It’s one of our favorites too.
Can you freeze these. I made a all batch thinking it wouldn’t be enough and now I have more than I can eat?
I haven’t but they may taste like ice cream. You’ll have to give it a try and let me know how they turn out.
This recipe does freeze really well. I use mini-muffin tins or just a cookie dough scoop on a trsy, then transfer to a sealed container. Bite-size “ice cream” desserts!!!
Perfect! Thanks so much for the tip!
I love simple and delicious recipes. I am definitely a huge peanut butter fan and this keto dessert looks fantastic. Can’t wait to try it!!
