Preheat oven to 350°F and line an 8x8-inch baking pan with parchment paper. Set aside.
In a medium bowl, combine the graham cracker crumbs, butter, cinnamon, and salt.
2 cups graham cracker crumbs, ½ cup unsalted butter, ¼ teaspoon ground cinnamon, ¼ teaspoon kosher salt
Press the mixture into the bottom of the prepared pan and pack it into a smooth, even layer.
Bake for 5 minutes, then set the pan aside to cool while you make the cheesecake layer.
Make Cheesecake:
In the bowl of a stand mixer fitted with the paddle attachment, beat together the cream cheese and granulated sugar until light and fluffy, about 1 minute.
24 ounces cream cheese, 1 cup granulated sugar
Add the heavy cream, peanut butter, and vanilla. Mix to combine. Scrape down the sides of the bowl as needed.
¼ cup heavy cream, ¾ cup creamy peanut butter, 1 teaspoon pure vanilla extract
With the mixer on low speed, add the eggs one at a time.
3 large eggs
Once all of the eggs have been incorporated, scrape down the sides of the bowl and make sure the batter is smooth.
Pour the cheesecake layer over the graham cracker crust and then bake for 35-40 minutes, or until the edges are golden brown and the center is just set.
Chill and Serve:
Remove the cheesecake from the oven and allow it to cool to room temperature, about 2 hours.
Once cooled, transfer the cheesecake to the refrigerator and allow it to chill (overnight is preferred, but at least 4 hours).
To serve, remove the cheesecake from the pan and slice it into bars.
Notes
*You can swap the graham cracker crumbs for Oreos, golden Oreos, or Biscoff cookies.**Use full-fat, brick-style cream cheese for the best results.***You can use brown sugar in place of granulated for a richer flavor.Becky's Top Tips:
Don't over-mix the batter when adding the eggs. This could cause the cheesecake to crack.
Let the cheesecake cool fully to room temperature before refrigerating to prevent cracking.
If the cheesecake starts to stick to the knife while slicing, just run it under hot water and wipe it clean with a towel. Repeat as needed.
Storage: Store peanut butter cheesecake bars in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 3 months.
