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:

  1. Almond butter
  2. Sunflower seed butter
  3. Coconut butter
  4. Macadamia nut butter
  5. Sesame seed butter (tahini)
  6. Cashew butter
  7. 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.

The sugar alcohols from Swerve are not included in the nutritional information since most subtract sugar alcohols to calculate net carbs.

    Made this tonight but used almond butter. It was so good. The chocolate chips definitely make this even better.

    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!

    1. I’ve never tried to freeze them bite size before but I don’t see why it wouldn’t work. Worth a try.

  3. Peanut Butter Heaven! Thanks so much for an awesome delicious recipe! I froze some of it and it was like ice cream,yum!

  4. 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.
