Preheat the oven: Set your oven to 325°F (163°C) to ensure it is hot and ready when you start baking the cheesecake.
Prepare the crust: In a mixing bowl, combine 1 1/2 cups chocolate cookie crumbs with 1/4 cup melted butter. Stir until the mixture resembles wet sand. Press this mixture firmly into the bottom of a 9-inch springform pan to form an even layer. Make sure to press the crumbs up the sides of the pan for added structure.
Mix the filling: In a large mixing bowl, beat 3 packages (8 oz each) softened cream cheese and 1 cup sugar together until smooth and creamy. This should take about 2-3 minutes, so the mixture is light and fluffy.
Add wet ingredients: Blend in 1 cup sour cream and 1 tsp vanilla extract until well combined. This will enhance the flavor and creaminess of your cheesecake.
Incorporate the eggs: Add 3 large eggs, one at a time, mixing gently after each addition. This helps maintain the airiness of the mixture.
Stir in the peanut butter: Add 1 cup creamy peanut butter to the mixture, folding it in carefully to ensure it's well mixed without deflating the batter.
Fold in the Reese’s: Gently fold in 15-20 chopped Reese’s peanut butter cups, making sure they are evenly distributed throughout the mixture.
Pour over the crust: Carefully pour the filling into the prepared crust, smoothing the top with a spatula.
Bake: Place the cheesecake in the preheated oven and bake for about 55-60 minutes, or until the edges are set but the center has a slight jiggle. Keep the oven door ajar for the last hour of cooling, allowing for gradual temperature adjustment.
Cool and chill: Let the cheesecake cool at room temperature for about an hour before transferring it to the refrigerator. Chill for at least 4 hours or overnight for the best flavor and texture.
Prepare the ganache: To make the ganache, heat 1 cup heavy cream in a small saucepan until it begins to simmer. Remove from heat and stir in 1/2 cup chocolate chips until smooth.
Top the cheesecake: Once the cheesecake is fully chilled, drizzle the ganache over the top. Finish by garnishing with the remaining Reese’s, 1/2 cup peanut butter chips, caramel sauce, and whipped cream if desired.
