In this post, we’ll explore how to create this delightful mousse, packed with flavor while keeping carbs at bay. Let’s dive into the world of keto-friendly desserts!
Ingredients List
To create the perfect Keto Peanut Butter Mousse, you’ll need the following ingredients:
- 1 cup heavy cream: This adds richness and creaminess to your mousse.
- 1/2 cup natural peanut butter: Choose a brand with no added sugars for a healthier option.
- 1/4 cup powdered erythritol: A keto-friendly sweetener that provides sweetness without the carbs.
- 1 teaspoon vanilla extract: For that extra layer of flavor.
- Pinch of salt: To enhance the sweetness and balance the flavors.
Substitution Suggestions:
- Nut Butters: If you’re allergic to peanuts, almond or cashew butter works well too.
- Sweeteners: Stevia or monk fruit sweetener can be used in place of erythritol, adjusting to taste.
- Dairy-Free Option: Substitute heavy cream with coconut cream for a dairy-free version.
Step-by-Step Instructions
Step 1: Whip the Cream
In a large mixing bowl, pour in the heavy cream. Using an electric mixer, whip the cream on medium speed until soft peaks form. This should take about 3-5 minutes.
Step 2: Combine Peanut Butter Mixture
In another bowl, mix the natural peanut butter, powdered erythritol, vanilla extract, and a pinch of salt. Stir until smooth and well combined.
Step 3: Fold the Mixtures Together
Gently fold the whipped cream into the peanut butter mixture using a spatula. Be careful not to deflate the whipped cream; the goal is to maintain that light, airy texture.
Step 4: Chill
Transfer the mousse into serving bowls or a large dish. Cover with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld and the mousse to set.
Step 5: Serve and Enjoy
Once chilled, serve your Keto Peanut Butter Mousse with a sprinkle of crushed nuts or a drizzle of sugar-free chocolate syrup for an extra touch!
