How to Make Peanut Butter Mousse Pie

Step 1: Prepare the Crust

Crush graham crackers into fine crumbs and mix with melted butter until evenly coated. Press the mixture firmly into a pie dish to form an even base. Chill it for at least 15 minutes to set while you prepare the filling.

Step 2: Whip the Cream

Beat heavy whipping cream using a mixer until soft peaks form. Gradually add powdered sugar and vanilla extract, then continue whipping until stiff peaks develop. This whipped cream is what gives the mousse its light, airy texture.

Step 3: Mix the Peanut Butter Filling

In a separate bowl, combine smooth peanut butter with a little more powdered sugar and a splash of vanilla. Gently fold this mixture into the whipped cream to maintain fluffiness while evenly blending the peanut butter flavor throughout.

Step 4: Assemble the Pie

Spread the peanut butter mousse evenly over the chilled crust, smoothing the top with a spatula. For an added touch, drizzle melted chocolate or sprinkle crushed peanuts on top before refrigerating.

Step 5: Chill and Serve

Refrigerate the pie for at least 3-4 hours, allowing the mousse to set perfectly into a creamy delight. Slice carefully and serve chilled for the best experience.

Pro Tips for Making Peanut Butter Mousse Pie

• Use Room Temperature Ingredients: This ensures even mixing and a smoother mousse texture.
• Don’t Over-whip the Cream: Stop at stiff peaks to prevent the cream from becoming grainy or turning to butter.
• Choose Natural Peanut Butter: For the best flavor and consistency, select peanut butter with minimal additives and oil separation.
• Chill the Pie Thoroughly: Patience here helps the mousse firm up perfectly, improving sliceability and taste.
• Crust Pressing Matters: Press the crust tightly into the pie dish to avoid crumbling and ensure a sturdy foundation.

How to Serve Peanut Butter Mousse Pie

Garnishes

Top the pie with whipped cream swirls, chopped roasted peanuts, chocolate shavings, or a drizzle of caramel sauce to elevate its look and flavor profile. Fresh berries can also add a pop of color and brightness.

Side Dishes

This pie pairs wonderfully with a scoop of vanilla ice cream, espresso shots, or light fruit salads to balance its rich texture. A cold glass of milk is, of course, a classic and comforting companion.

Creative Ways to Present

Serve individual portions in clear dessert cups or mason jars for a fun twist, or create mini peanut butter mousse pie tarts for bite-sized indulgence at parties and gatherings.

Make Ahead and Storage

Storing Leftovers

Wrap leftover Peanut Butter Mousse Pie tightly with plastic wrap and store in the refrigerator for up to four days. Keeping it cold maintains its creamy texture and fresh flavor.

Freezing

You can freeze the pie for up to two months. Cover it securely with foil and plastic wrap to prevent freezer burn. Thaw overnight in the refrigerator before serving to retain its mousse-like consistency.

Reheating

Since this is a cold mousse pie, reheating is not recommended. Instead, allow the pie to come to slightly below room temperature if preferred, but serving it chilled is best for maximum flavor and texture enjoyment.

FAQs

Can I use crunchy peanut butter instead of smooth?

Yes, crunchy peanut butter can add a delightful texture contrast, but be aware it will slightly change the smoothness of the mousse.

Is it necessary to use a pre-made crust?

Not at all; making your own graham cracker crust with crushed cookies and butter is simple and yields the freshest, best-tasting base.

How long does the Peanut Butter Mousse Pie last in the fridge?

The pie will stay fresh and delicious for up to four days when properly covered and refrigerated.

Can I make this pie nut-free for someone with allergies?

This particular recipe centers on peanut butter, so it isn’t suitable for nut-free diets. However, you could experiment with seed butters like sunflower seed butter as a substitute.

What is the best way to get clean slices of this mousse pie?

Use a sharp knife dipped in warm water and wiped dry between each cut to achieve smooth, clean slices without crumbling the mousse or crust.
