How to Make Peanut Butter Mousse 

For this recipe, you will need peanut butter, cream cheese, heavy cream, and powdered sweetener.

In a medium mixing bowl, beat together the cream cheese, peanut butter, and powdered sweetener until smooth.

In a separate bowl, whip the heavy cream until stiff peaks form. You want it to hold its shape when the beaters are lifted.

Gently beat about a quarter of the whipped cream into the peanut butter mixture. This softens the texture and makes it easier to fold in the rest.

Fold in another ½ of the whipped cream, then add the remaining portion until fully combined. Use a spatula to foldgently so you don’t deflate the mousse.

Spoon or pipe the mousse into jars, ramekins, or bowls. Enjoy immediately for a soft mousse, or refrigerate for at least 30 minutes for a firmer, chilled dessert.

Add crushed peanuts, a dollop of whipped cream, dark chocolate shavings, or a sprinkle of cinnamon for a finishing touch.

How to Use and Customize This Peanut Butter Mousse

This mousse is versatile enough to serve on its own or dress up for special occasions. Here are a few ideas and substitution options to suit your tastes or dietary needs:

• Serve it solo: Pipe it into small jars, bowls, or ramekins and top with crushed peanuts, chocolate curls, or a drizzle of melted dark chocolate.
• Make it a parfait: Layer with crushed keto cookies, chocolate chips, or fresh raspberries for a no-bake parfait.
• Use it as frosting: This mousse doubles as a thick, pipeable frosting for cupcakes or low-carb brownies.
• Make it dairy-free: Use a dairy-free cream cheese (like Kite Hill or Miyoko’s) and substitute the heavy cream with full-fat coconut cream. Be sure to whip the coconut cream until fluffy.
• Switch the sweetener: I used powdered erythritol to keep it low-carb, but you can use regular powdered sugar, monk fruit blend, or allulose if preferred.
• Change the nut butter: Almond butter or cashew butter work too—just make sure it’s thick and creamy, not too runny.

FAQ

Can I make this peanut butter mousse ahead of time?

Yes! In fact, the texture improves after a short chill. You can make it up to 2 days in advance and store it in an airtight container or individual jars in the fridge.

Is this mousse keto-friendly?

It is if you use powdered erythritol or another low-carb sweetener. Stick to natural peanut butter with no added sugar for best results.

Can I freeze this mousse?

Yes, it freezes beautifully! Freeze in small portions and thaw in the fridge overnight before serving. It also makes a delicious frozen treat if served semi-frozen, like ice cream.

Can I make this without a mixer?

While it’s possible to make this by hand, using a hand mixer or stand mixer will make the job much easier—especially for whipping the cream.
