Keto Peanut Butter Mousse (2024)

This creamy, airy keto peanut butter mousse recipe is so quick and easy. It requires just 5 ingredients and you can whip it up in 5 minutes.

You won't be able to resist this low carb peanut butter mousse! It has an impossibly silky, fluffy texture and it is packed with deep peanut butter flavor. You'll also love the fact that one serving contains only 2.3g net carbs!

Piped into pretty dessert cups, this keto mousse has enough wow factor to be served at a dinner party. It is one of my go-to sugar free dessert recipes when I have short-notice guests.

Ingredients

Here are the ingredients you'll need:

• Smooth peanut butter: Must be soft and creamy. Room temperature is best. I like Manilife deep roast peanut butter, which is slightly salted.
• Mascarpone: This is a smooth, rich Italian cream cheese. You can replace it with cream cheese.
• Heavy cream: Whipped to soft peaks.
• Powdered sweetener: I used a monk fruit sweetener blend, but you can use pure powdered erythritol, xylitol, allulose or Swerve confectioners.
• Vanilla extract: Optional, but recommended.

See the recipe card for full information on ingredients and quantities.

Instructions

Step 1

Add the mascarpone or cream cheese, sweetener, peanut butter and vanilla to a large mixing bowl. Mix with an electric hand mixer to combine.

Step 2

In another large bowl, whip the cold cream until just below stiff peaks.

Step 3

Fold the heavy whipping cream through the peanut butter mixture until combined and smooth.

Step 4

Spoon into a glass or use a piping bag.

Toppings

The mousse tastes great solo. Here are some ideas for toppings to make it look pretty:

• Drizzle of peanut butter
• crumbled keto ginger snaps, keto sugar cookies or keto chocolate cookies
• chopped keto peanut butter cups
• sugar-free chocolate chips
• crushed roasted peanuts
• whipped cream

Variations

• Chocolate peanut butter mousse: Add 2 tablespoons unsweetened cocoa powder
• No peanut butter: Use almond butter or any other nut butter
• Make it dairy free: Use dairy-free cream cheese and whipped coconut cream instead of heavy cream.
