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 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!
