  • low-carb sweetener (I used Swerve confectioners)
  • heavy whipping cream

What low-carb sweetener to use for this Keto Peanut Butter Mousse?

Any low-carb sweetener should work.

For mousse recipes, I personally always use confectioners Keto sweeteners, because they dissolve better. I don’t like feeling the granules from erythritol in the mousse.

I recommend either Swerve or powdered erythritol.

The amount of sweetener in the recipe is minimal, so feel free to add some more if it is not too sweet for you.

How to make Keto Peanut Butter Mousse?

I recommend using an electric mixer.

In a bowl beat together the sweetener and cream cheese for 1 minute.

Add peanut butter and beat until combined. Scrape down the sides and bottom of the bowl.

With the mixer running on medium, slowly add the heavy cream, beating until light and fluffy.

divide the mousse between 4 cups and chill for 15 minutes.

Serve.

Keto Peanut Butter Mousse without Cream cheese

I’ve shared a lot of Keto dessert recipes on my blog in the last year and I’ve had some people tell me that they would like recioes without cream cheese.

As you may have noticed, I also love mascarpone cheese. It produces creamier, buttery mousses compared to cream cheese. The good news is that you can substitute cream cheese with mascarpone cheese in this mousse recipe.
