Ingredients

Keto Peanut Butter Mousse (2)

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 2

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

Keto Peanut Butter Mousse (5)

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

Expert Tips

Peanut butter: If your peanut butter does not contain salt, add a pinch of sea salt to the recipe. It really lifts the taste.

Ingredient temperature: I used cold mascarpone straight from the fridge because I wanted to serve my mousse straight away. Some recipes recommend using room temperature cream cheese (or mascarpone). I honestly don't think it makes a difference as long as you use a quality product. The cream should definitely be cold - it whisks up much better that way.

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.

Recipe FAQs

Can you make peanut butter mousse ahead?

Yes, you can make this recipe a day or two ahead. Simply store it in the fridge until ready to serve.

Can I use crunchy peanut butter?

You could, but it may be difficult to use a piping bag.

How can I make the mousse lighter in calories?

You can replace the cream cheese with Greek yogurt. Or try my peanut butter yogurt instead!

    I have this major urge to make this right now! I really like your recipes and already subscribe to your emails. I would "almost" never change anything in a recipe of yours, but think I want to change the order up on this one - making the whipped cream first, maybe with half the sweetener, only because it will taste better when I lick the beaters. If I whipped the cream cheese/peanut butter first I would need to at least do a finger clean on the beaters before whipping the cream, and I really don't enjoy cleaning beaters. Maybe the cream would whip anyway, but rather than mess it up, I will change the order. I live alone, so don't mind the licking bit. Also, I will save on cleanup and fold and leave it in the one bowl. Pretty sure it will be just 2 servings! HaHa!

    This recipe looks delicious and will definitely going to try it, but I was wondering if instead of peanut butter I can use instant coffee too.
