Ingredients You'll Need

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. Here's what you'll need to make it:

• Heavy Whipping Cream: Rich heavy whipping cream is part of the base of the mousse, bringing a thick texture, light color, and subtle sweetness. When whipped, the cream becomes fluffy and light which is the optimal texture of the mousse.
• Cream Cheese: Alongside whipping cream is cream cheese, a tangy flavored ingredient thickening the mousse to help it become silky smooth. Allowing the cream cheese to soften to room temperature will make it easier for the blender to do so, so remove it from the refrigerator an hour or so before you plan to make the mousse.
• Peanut Butter: Peanut butter flavors take center stage with this mousse, and to keep things keto-friendly, it’s best to use natural, unsweetened peanut butter. Using smooth peanut butter keeps it in line with the other ingredients, which are all smooth and silky, so there are no lumps in the final mousse.
• Low Carb Sugar Substitute: A powdered low-carb sugar substitute is the perfect sweet addition to the mousse, as it blends well and doesn’t leave any bits or lumps behind. Instead, the powdered sugar replacement brings a light sweetness that doesn’t take away from the natural earthiness of the peanut butter or delicate vanilla flavor.
• Vanilla Extract: Vanilla adds sweetness to the mousse, but it also lightens the overall flavor, uniting ingredients together in the dessert. High-quality unsweetened vanilla extract is an ideal choice as it has a well-rounded vanilla flavor that isn’t sweetened by glucose syrup, sugar, or artificial flavorings.
• Salt: A sprinkling of salt in sweet recipes helps bring balance and enhances the flavors within the mousse. Salt helps bring out the nutty peanut butter notes and uplifting notes of vanilla, just be sure to only add a small amount to avoid making an overly salty mousse!

How To Make Keto Peanut Butter Mousse

Our keto peanut butter mousse is effortless, with an electric blender doing most of the hard work. Containing familiar ingredients and requiring just 10 minutes of prep time, our mousse recipe is one to keep on standby when the sweet cravings hit or you need a family dessert this weekend. Let the kids enjoy the fun by garnishing the mousse with their favorite topping, such as grated dark chocolate, chopped peanuts, or shredded coconut.

1. Using an electric blender, beat the whipping cream for 3-5 minutes until it doubles in size and holds firm peaks. Set aside, preferably in the fridge, until the other ingredients are ready to be incorporated.

2. Whisk the cream cheese, peanut butter, powdered sweetener, vanilla extract, and a pinch of salt together until combined.

3. Remove the whipped cream from the refrigerator and fold the cream cheese mixture into the cream with a spatula until all the ingredients have united with no streaks of peanut butter or cream.

4. Serve immediately for a soft mousse texture, or refrigerate for 1-2 hours so the mousse can set even more. Serve cold alone or garnish with simple low-carb toppings.
