Health Benefits of This Peanut Butter Mousse

Aids in Blood Sugar Control

Peanut butter on its own is packed with fat and protein, making it an excellent choice for blood sugar control. However, most peanut butter mousse recipes call for copious amounts of sugar, which leaves you in blood sugar mayhem.

As is true for all keto desserts, this peanut butter mousse skips the sugar entirely and opts for stevia instead. Stevia not only imparts a sweet taste, but it also helps your body become sensitive to glucose (from sugar), and may even be beneficial for those with diabetes[*].

Supports Joint Health

Dessert recipes are made to be enjoyed, but why not add in a little extra nutrition if you can? In this recipe, the addition of collagen powder not only ups the protein content, but it provides direct support to your joints as well.

Collagen is the primary component of connective tissue and provides the amino acids that your body needs for healthy cartilage[*]. Cartilage is a rubbery tissue that protects the ends of your bones and joints. It provides support, while also allowing for flexibility and movement. When you start to wear out your cartilage, however, joint pain and stiffness can result.

Therefore, providing your body with the building blocks it needs by including collagen in your diet offers you continued joint support.

Next, slowly add in your stevia powder and collagen and continue to whip, soft peaks should remain. Once the stevia and collagen are fully incorporated, use a spatula to fold in the peanut butter.

In a separate medium bowl add two teaspoons of gelatin and two tablespoons of warm water. Stir well until the gelatin is dissolved.
