This Keto Peanut Butter Mousse is a rich, creamy, and satisfying low-carb dessert that delivers all the indulgence of a classic mousse without the added sugar. I love how the combination of peanut butter, cream cheese, and whipped cream creates a light, fluffy texture with a deep nutty flavor. Best of all, it comes together in just a few minutes and requires no baking.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
1 cup creamy peanut butter
1 cup softened cream cheese
1/3 cup powdered keto sweetener
1 cup heavy whipping cream
1 teaspoon vanilla extract
Pinch of salt
Directions
I beat the softened cream cheese, peanut butter, powdered keto sweetener, vanilla extract, and salt together in a large mixing bowl until the mixture becomes smooth and creamy.
In a separate bowl, I whip the heavy cream until stiff peaks form.
I gently fold the whipped cream into the peanut butter mixture, being careful not to deflate the air, until the mousse becomes light and fluffy.
Then I spoon or pipe the mousse into individual serving cups.
I chill the mousse for at least 30 minutes before serving to achieve the best texture and flavor.

Variations
I sometimes add a tablespoon of unsweetened cocoa powder for a chocolate peanut butter mousse.
I like mixing in a few drops of sugar-free caramel flavoring for extra richness.
Occasionally I top the mousse with chopped roasted peanuts for added crunch.
I enjoy adding a small amount of cinnamon to create a warm, spiced flavor profile.
I can also replace peanut butter with almond butter for a slightly different keto-friendly version.
Storage/Reheating
I store any leftover mousse in an airtight container in the refrigerator for up to 4 days. The texture stays creamy and delicious when kept chilled. For longer storage, I freeze individual portions for up to 2 months and thaw them in the refrigerator before serving. Since this is a no-bake dessert, reheating is not necessary. I simply enjoy it straight from the refrigerator.
FAQs
Can I make this mousse ahead of time?
Yes, I often prepare it a day in advance. Chilling overnight helps the flavors develop and improves the texture.
Can I use natural peanut butter?
Yes, I can use natural peanut butter, but I make sure it is well stirred before mixing since oil separation can affect the consistency.
Is this mousse gluten-free?
Yes, the mousse is naturally gluten-free as long as all packaged ingredients used are certified gluten-free.
Can I freeze Keto Peanut Butter Mousse?
Yes, I can freeze it in airtight containers for up to 2 months. I thaw it in the refrigerator before serving.
How can I make the mousse sweeter?
I simply add a little more powdered keto sweetener and taste as I go until I reach my preferred level of sweetness.
Conclusion
I find this Keto Peanut Butter Mousse to be one of the easiest and most satisfying low-carb desserts to make. Its creamy texture, rich peanut butter flavor, and quick preparation make it a wonderful choice for anyone following a keto lifestyle or simply looking for a delicious sugar-free treat. Whether I serve it at a gathering or enjoy it as a personal indulgence, this mousse always delivers a smooth, fluffy, and irresistible dessert experience.
