Keto PB & J Mousse

This mousse is whipped heavy cream folded into a sweetened peanut butter base, then layered or swirled with sugar-free jam to give it a peanut butter and jelly flavor. There is no cooking. It takes 10 minutes to mix and at least 30 minutes to set in the fridge, so the total is 40 minutes. The recipe makes 4 servings.

Save this recipe for later:

Each serving has about 4 grams of carbohydrates, since the sweetener is erythritol and both the peanut butter and the jam are sugar-free.

What Goes in the Mousse

• Heavy whipping cream (1 cup): whipped to soft peaks. It gives the mousse its light, creamy texture.
• Sugar-free creamy peanut butter (1/2 cup): the main flavor. Crunchy peanut butter also works and adds more texture.
• Powdered erythritol (1/4 cup): sweetens the peanut butter. Use another keto sweetener if you prefer.
• Vanilla extract (1 teaspoon) and a pinch of salt: the salt balances the sweetness.
• Sugar-free raspberry or strawberry jam (1/4 cup): the jelly part. Blueberry or cherry jam work as well.

Folding and Layering

Whip the cream with an electric mixer until soft peaks form. A whisk works too, but it takes longer, and the fluffier the cream is, the creamier the mousse will be. In another bowl, mix the peanut butter, erythritol, vanilla and salt until smooth. Bring the peanut butter to room temperature first so it blends easily.

Fold the whipped cream into the peanut butter mixture gently. Folding too much deflates the cream and makes the mousse denser, so stop once it is fully combined.

Divide the mousse between serving dishes, layering it with the jam. You can also swirl the jam in for a marbled look. Clear glasses show the layers. Refrigerate for at least 30 minutes so the mousse sets.

Ways to Change It

• Chocolate: stir 2 tablespoons of unsweetened cocoa powder into the peanut butter mixture.
• Toppings: crushed almonds or pecans, or unsweetened coconut flakes, add crunch.
• Jam: any flavor of sugar-free jam can go in.
• Dairy-free: replace the cream with coconut cream or a dairy-free whipping cream. Choose an unsweetened one.

What to Serve With It

Fresh strawberries or raspberries, or a small fruit salad, cut through the richness. A dollop of whipped cream or coconut cream goes on top. Herbal tea or sugar-free iced coffee suits the sweetness of the dessert.
