Step 1: Prepare the Crust

1. In a bowl, combine crushed graham crackers or Oreos with melted butter and sugar (if using).
2. Mix until the texture resembles wet sand.
3. Press the mixture firmly into the bottoms of mini pie tins, muffin liners, or silicone molds.
4. Place the crusts in the refrigerator to set while preparing the filling.

Step 2: Make the Peanut Butter Filling

1. In a large mixing bowl, beat the peanut butter, softened cream cheese, and powdered sugar until smooth and creamy.
2. Fold in the whipped topping gently to maintain a light, fluffy texture.
3. Spoon the filling into the prepared crusts, smoothing the tops with a spatula.

Step 3: Add the Chocolate Topping

1. In a microwave-safe bowl, combine the chocolate chips and heavy cream.
2. Microwave in 30-second intervals, stirring each time, until the chocolate is fully melted and smooth.
3. Allow the chocolate ganache to cool slightly, then spoon it over the peanut butter filling.

Step 4: Chill and Serve

1. Refrigerate the assembled pies for at least 2-3 hours or until fully set.
2. Before serving, add optional toppings like chopped peanuts or a drizzle of caramel.
