Step 1: Prepare the Crust

1. Preheat your oven to 325°F (165°C).

2. In a medium bowl, mix together graham cracker crumbs, sugar, and melted butter.

3. Press the mixture into the bottom of a 9-inch springform pan to form an even crust.

4. Bake for 8-10 minutes, then remove from the oven and set aside to cool.

Step 2: Make the Cheesecake Filling

1. In a large mixing bowl, beat together the cream cheese and sugar until smooth.

2. Add the eggs one at a time, mixing well after each addition.

3. Stir in vanilla extract and peanut butter until fully combined.

4. Gradually add the heavy cream and mix until smooth.

Step 3: Bake the Cheesecake

1. Pour the cheesecake filling over the cooled crust.

2. Smooth the top with a spatula.

3. Bake for 50-60 minutes, or until the center is just set (with a slight jiggle).

4. Turn off the oven and leave the cheesecake inside with the door slightly ajar for 1 hour.

5. Refrigerate the cheesecake for at least 4 hours or overnight to fully set.

Step 4: Prepare the Chocolate Ganache

1. In a heatproof bowl, combine chopped chocolate and heavy cream.

2. Microwave in 20-second intervals, stirring each time, until the chocolate is completely melted and smooth.

3. Let the ganache cool slightly before pouring it over the chilled cheesecake.

Step 5: Prepare the Peanut Butter Drizzle

1. In a small bowl, whisk together peanut butter, powdered sugar, and milk until smooth.

2. Add more milk if needed to reach a pourable consistency.

Step 6: Assemble the Cheesecake

1. Once the ganache has set, drizzle the peanut butter mixture over the top in a decorative pattern.

2. Slice and serve!
