Step-by-step instructions
Make the crust: In a mixing bowl, combine the crushed cookies and melted butter until fully integrated. Press this mixture firmly into the bottom and up the sides of a pie dish. Allow it to chill in the fridge while you prepare the filling.
Prepare the filling: Using an electric mixer, beat together the cream cheese and peanut butter until the mixture is smooth and creamy.
Incorporate dry ingredients: Add in the powdered sugar and vanilla extract, continuing to mix until everything is well combined.
Whip the cream: In a separate bowl, whip the chilled heavy cream until soft, fluffy peaks form.
Fold mixtures together: Gently fold the whipped cream into the peanut butter mixture until it becomes light and mousse-like.
Spread the filling: Evenly spread the mousse filling over the chilled crust, smoothing the top with a spatula. Refrigerate for at least 2 hours to allow it to set.
Make the ganache: Heat the heavy cream in a saucepan until it just starts to simmer. Pour this hot cream over the chocolate chips and a pinch of salt. Allow it to sit for 1 minute, then stir until smooth and glossy.
Top the pie: Pour the ganache over the chilled mousse layer, spreading it evenly. Refrigerate for an additional 30 to 60 minutes, or until the ganache is set.
Serving suggestions
When it comes time to serve, make your presentation pop! Consider garnishing with crushed peanuts or a sprinkle of cocoa powder for added flair. This pie pairs perfectly with a dollop of whipped cream on the side or even a scoop of vanilla ice cream. It’s a show-stopping dessert that’ll leave your guests raving!
How to store
If you have leftovers (though it’s unlikely!), you can store the pie in an airtight container in the refrigerator for up to four days. Just make sure it’s well-covered to maintain freshness. Unfortunately, this pie doesn’t freeze well due to its creamy texture, so it’s best enjoyed fresh.
Helpful cooking tips
- For the ultimate chocolate experience, add a little espresso powder to the ganache for a mocha twist.
- Be cautious not to overwhip the cream; stop when soft peaks form for the best mousse consistency.
- If you’re short on time, pre-made chocolate cookie crusts can be a great shortcut!
Creative twists
Mix things up a little! Here are some fun variations:
- Crunchy cookie crust: Use a mixture of chocolate and graham cracker crumbs for added texture.
- Nutty flavor: Swirl in chopped peanuts into the mousse for an extra crunch.
- Alternative toppings: Drizzle caramel sauce over the chocolate ganache for a sweeter surprise!
