1. Preheat the oven to 325°F.

For the crust:

1. In the bowl of a food processor, process the crackers and sugar until finely ground. Add the butter and pulse until moistened. Use the bottom of a measuring cup, glass, or ramekin to press the crust mixture into the bottom and up the sides of a 9-inch pie plate. Bake until fragrant, about 10 to 12 minutes. Cool completely on a wire rack.

For the filling:

1. In a large bowl, use an electric mixer to beat the cream cheese, 3/4 cup powdered sugar, and the peanut butter until light and fluffy, about 3 minutes.

2. In a separate bowl, use an electric mixer with the whisk attachment to whip the heavy cream until thick and light. Add in the remaining 2 tablespoons of powdered sugar and the vanilla extract and continue to whip until stiff peaks form.

3. Gently fold the whipped cream into the peanut butter mixture. Pour into the prepared pie shell and freeze for 3 hours or chill in the fridge at least 6 hours.

4. Place your melted peanut butter and melted chocolate in separate resealable bags or piping bags. Snip off a tiny corner of the bag's tip. Squeeze slightly to drizzle the melted peanut butter and melted chocolate over your pie. Top with mini Reese's cups and peanut butter chips. Serve frozen or refrigerated.

5. Store in the fridge, covered, for up to 3 days, or in the freezer for up to 1 month.
