Keto Peanut Butter Mousse

Peanut butter lovers get ready to jump for joy.

Soft and buttery a bowl of mousse is always a crowd-pleaser, and this keto peanut butter mousse is the perfect example.

Sweet and comforting, earthy and light as air, it’s the kind of dessert that one generous spoonful will put a big smile on your face.

Besides being the perfect keto pick-me-up it can also be used as frosting for your favorite keto cakes or pie and tart filling.

Serve it in a wine or Martini glass for a nostalgic 90s vibe.

Keto Peanut Butter Mousse

For this delicious low carb mousse you’re going to need:

  • 1/2 cup Heavy Whipping Cream
  • 1/2 cup Cream Cheese (at room temperature)
  • 3 tbsp Peanut Butter (unsweetened)
  • 1/4 cup Erythritol
  • 1 tsp Vanilla Extract
  • 1/4 tsp Salt

First, beat your whipping cream with an electric blender.

This will take bout 3-5 minutes and it should double in size and hold firm peaks.

Set this aside in the fridge.

Next, whisk together the cream cheese, peanut butter, erythritol, vanilla and a pinch of salt.

Finally, grab your whipping cream and fold the cream cheese mixture into it with a spatula until thoroughly combined.

You can serve this delicious keto peanut butter mousse straight away but I recommend you let it set in the refrigerator for 1-2 hours if you can!

It will set more and is always better cold.

I hope you enjoy this recipe, let me know how it went in the comments!
