Graham Cracker Crust
- 1 1/2 cups graham cracker crumbs
- 6 tablespoons melted butter
Peanut Butter Mousse Filling
- 1 cup creamy peanut butter
- 1 cup heavy whipping cream
- 1/2 cup powdered sugar (plus extra for the mousse)
- 1 teaspoon vanilla extract
Optional Toppings
- Melted chocolate for drizzling or folding into mousse
- Crushed peanuts
- Chocolate shavings
- Whipped cream swirls
- Caramel sauce
- Fresh berries
- Prepare the Crust: Crush graham crackers into fine crumbs and mix thoroughly with melted butter until the mixture is evenly coated. Press this mixture firmly into the bottom of a pie dish, creating an even layer. Chill the crust in the refrigerator for at least 15 minutes to set while you prepare the filling.
- Whip the Cream: Using a mixer, beat the heavy whipping cream until soft peaks form. Gradually add the powdered sugar and vanilla extract, continuing to beat until stiff peaks develop. This whipped cream forms the airy base of the mousse.
- Mix the Peanut Butter Filling: In a separate bowl, combine the creamy peanut butter with a little additional powdered sugar and a splash of vanilla extract. Gently fold this mixture into the whipped cream, taking care to maintain the light and fluffy texture while evenly distributing the peanut butter flavor.
- Assemble the Pie: Spread the peanut butter mousse evenly over the chilled crust, smoothing the top with a spatula. For extra flair and flavor, drizzle melted chocolate or sprinkle crushed peanuts on top as desired before placing the pie back in the refrigerator.
- Chill and Serve: Refrigerate the assembled pie for at least 3 to 4 hours, allowing the mousse to set into a creamy, firm texture. Slice carefully with a sharp knife for clean servings, and serve chilled for best taste and texture.
Notes
- Use room temperature ingredients to ensure smooth mixing and optimal mousse texture.
- Do not over-whip the cream; stop at stiff peaks to avoid graininess or butter formation.
- Choose natural peanut butter with minimal additives for the best flavor and consistency.
- Press the crust firmly into the dish to avoid crumbling and ensure a sturdy base.
- Chill the pie thoroughly to help the mousse set well and improve sliceability.
- To get clean slices, use a sharp knife warmed in hot water and dried between cuts.
