🥄 Ingredients You’ll Need
- Peanut Butter – Smooth and creamy works best here (skip the natural kinds that separate).
- Cream Cheese – Full-fat is ideal for the creamiest texture, but low-fat works in a pinch.
- Powdered Sugar – Also called confectioners’ sugar, it sweetens and thickens the mousse.
- Heavy Cream – Whipped to stiff peaks to give the mousse its light, fluffy texture.
- Vanilla Extract (optional) – A touch of vanilla adds depth and warmth.
👩🍳 How to Make Peanut Butter Mousse
Step 1: Mix the Base
In a large bowl, beat together the peanut butter, cream cheese, powdered sugar, and vanilla until smooth and creamy.
Step 2: Whip the Cream
In a separate bowl, whip the heavy cream until stiff peaks form.
Step 3: Fold Together
Gently fold the whipped cream into the peanut butter mixture in batches until light and fully combined.
Step 4: Pipe and Serve
Transfer the mousse to a piping bag fitted with a star or swirl tip. Pipe into serving jars or bowls and enjoy right away—or refrigerate for at least 30 minutes for an extra thick, chilled mousse.
💡 Tips for the Best Peanut Butter Mousse
- Chill it for thicker texture. Let it rest in the fridge before serving.
- Get creative with toppings. Crushed peanuts, chocolate chips, whipped cream, or caramel drizzle take it over the top.
- Nut-free option? Use tahini or sunflower seed butter for a delicious allergy-friendly version.
- Make it a parfait. Layer with crushed cookies, chopped nuts, or chocolate shavings for an easy no-bake dessert.
- Use it as a filling. It’s thick enough to use in cakes, cupcakes, or cookie sandwiches!
🧊 Storage Instructions
- To Store: Keep covered in the refrigerator for up to 2 weeks.
- To Freeze: Store in an airtight, freezer-safe container for up to 6 months. Thaw overnight in the fridge before serving.
