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
This peanut butter mousse has just 2g of net carbs per serving. This serving size is based on six equal-sized servings.

- 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.

Love this! Do you have the calories per serving?
Yes, according to MyFitnessPal app each serving is 140 calories.
I know this make about 8 servings, does anyone have any idea about how many grams that is?
I weighed mine out, the whole lot came to 12 oz so that is 1.5 oz per serving. I’m in love!
Thanks!
I just made this for the hubby and I. OH. MY GOODNESS! This stuff is amazing and I feel like I’m cheating! Just what we needed on this cool December evening. ❤
Awesome! So glad you loved it.
I used slightly crunchy pb in this and it tastes like a Butterfinger. A go to recipe.
Crunchy is my favorite!
I am so glad I found you and have just read about you sounds like you’re an amazing lady and I look forward to learning more things about your blog I have been having trouble doing the low carb recipes and I sure look forward to seeing the different things that you post also I’m a grandmother of 11 definitely want to stay in shape may God bless you on your journey he always blesses me.
Thank you so much for your kind words. Blessings to you!
What is the calorie count (not macros) for each please? Looks yummy!
140 calories
This looks amazing! Question, does it get solid in the fridge like a macaroon-shape, or does it need to be eaten with a spoon. Just wondering how to prepare to serve it at a friend’s house ?
You can eat it with a spoon. It gets thicker than pudding but not like a cookie if that makes sense. It’s truly a “fluff.” My mother-in-law spooned out individual servings on a cookie sheet and let them get cold. Then, she put them in a container. I leave mine in a container and we just spoon out a serving at a time since it’s just my hubby and I that eat it.
For the recipe you posted, (which sounds amazing, btw!) how many servings does it make? I want to make sure I’m portioning correctly in case I want to eat it ALL!
8 servings. So glad you love it!
I’m not sure if it’s because I haven’t had any sugar in so long or these are really just that good! So easy and yummy when you’re having a horrible sweet tooth day!! Thank you 🙂
Great! I’m so glad you loved it. I think it tastes like peanut butter pie.
I see it makes 8 servings, what is the individual serving size?
I didn’t measure I just divided it 8 equal ways.
I don’t use packets of stevia but I have liquid stevia or granulated erythritol. Can you give me the equivalent of 3-4 stevia packets please? Thank you!
Perhaps this link would be helpful.

Iv made them but made little bite sized portions… is the whole mixture to make the 8 portions you have calculated… trying to work out its calories etc.
Yes, the entire mixture is 8 portions.
I’m trying out Keto desserts for my mom and I have never worked with stevia. How much in ounces would 3-4 packets be?
I’m not sure. I would start by adding a teaspoon then tasting and adding more until you love it.
What kind of peanut butter did you use? I found one with only peanuts & salt as the ingredients. Most in the store had some sort of sugar added.
I use Smucker’s natural peanut butter. It doesn’t have any added sugars at all.
Do you have an eyeball estimate of how much each serving is? It was delish!
I just spoon it out in 8 equal servings. Probably a little more than a tablespoon off the top of my head.
Can you substitute the cream cheese for something else? I don’t like cream cheese at all, so when I made it I just could taste the cream cheese too much… Is there a way to make it with something else?
You could try leaving it out and see how it tastes or cutting the amount in half.
Try mascarpone cheese – similar texture and consistency but different flavor.
I have powdered Swerve, can I use that in place of the Stevia or does it need to be the granules? Thanks!
I think it would work just fine.
