Ingredient notes:

Use the exact measurements in the recipe card below. A few notes on ingredient choices:

Four small bowls filled with vanilla extract, cream cheese, maple syrup and peanut butter.
  • Peanut butter: choose smooth, unsweetened or natural peanut butter for the best texture and flavour.
  • Cream cheese: plain, unflavoured cream cheese works best; use a dairy-free alternative to make the recipe vegan.
  • Maple syrup: provides natural sweetness; agave can be substituted if preferred.

Variations and add-ins:

  • Dairy-free / vegan: swap in a dairy-free cream cheese.
  • Nut-free option: use cashew or sunflower seed butter instead of peanut butter.
  • Paleo: cashew butter is a good substitute for peanut butter.
  • Three-ingredient version: omit the vanilla extract to make it with just cream cheese, peanut butter and maple syrup.
  • Chocolate twist: stir in a few chocolate chips or fold in cocoa powder for chocolate peanut butter mousse.

Top tips:

  • Soften the cream cheese: letting cream cheese come to room temperature makes blending faster and smoother.

How to serve:

  • In cups or ramekins: garnish with whipped cream, coconut whipped cream, chocolate chips or shavings.
  • As a dip: use it for dipping fruit, cookies or crackers.
  • As a filling: great for pies, cupcakes or layer cakes and ideal for a peanut butter pie.
  • As a topping: spoon over overnight oats, oatmeal, crepes, grain-free waffles or muffins.
  • Make parfaits: layer the mousse with whipped cream, cookie crumbs, nuts or chocolate pieces.

Peanut butter mousse FAQs:

Why is mousse so fluffy?

Mousse is meant to be light and airy. Beating the ingredients with a hand or standing mixer incorporates air into the mixture, producing a fluffy texture similar to whipped cream.

Is this mousse keto?

No — this version is not low carb. To adapt it for keto, try a keto-friendly liquid sweetener, but results may vary as the recipe has not been tested with those substitutes.

How should I store this mousse?

Keep the mousse in an airtight container in the refrigerator for up to two weeks.

Can I freeze this mousse?

Yes. Freeze in an airtight container for up to six months. Thaw overnight in the refrigerator before serving.
