What’s in the Gear List
- Food Processor – to crush Oreos into fine crumbs

- Electric mixer – to easily cream the ingredients

Stepwise Method: Cheesecake Peanut Butter Bars

Step 1: Prepare the Crust
Begin by preheating your oven to 350°F (175°C). In a food processor, crush the 36 Oreos into fine crumbs. Transfer the crumbs to a mixing bowl and pour in the melted salted butter. Stir until the mixture resembles wet sand. Press this mixture firmly into the bottom of a lined 9×9 inch baking pan. Bake for 10 minutes, then remove and let it cool slightly.
Step 2: Make the Cheesecake Filling
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Gradually add the granulated sugar, mixing until well combined. Next, beat in the peanut butter and vanilla extract until fully incorporated.
Step 3: Add the Eggs
Add the two large eggs, one at a time, mixing on low speed after each addition until just combined. Be careful not to overmix, as this can cause the cheesecake to crack during baking.
Step 4: Pour and Bake
Pour the cheesecake filling over the cooled Oreo crust, smoothing the top with a spatula. Bake in the preheated oven for approximately 25-30 minutes, or until the edges are set and the center has a slight jiggle. Remove from the oven and let it cool to room temperature.
Step 5: Chill and Slice
Once cooled, refrigerate the cheesecake bars for at least 4 hours or overnight, which helps them set and makes slicing easier. Once chilled, lift the bars out of the pan using the edges of the parchment paper. Cut into squares and serve.
Spring–Summer–Fall–Winter Ideas

- Spring: Add a layer of fresh strawberries on top for a fruity twist.
- Summer: Serve with a scoop of vanilla ice cream for a refreshing dessert.
- Fall: Incorporate a touch of pumpkin spice into the filling for a seasonal flair.
- Winter: Drizzle with melted chocolate and sprinkle crushed peppermint for a festive touch.
Avoid These Mistakes
When making your Cheesecake Peanut Butter Bars, keep these common pitfalls in mind:
- Overmixing the cheesecake filling can lead to cracks.
- Not allowing the bars to chill adequately can result in a soft texture.
- Forgetting to line the pan can make it difficult to remove the bars.
- Using cold cream cheese may lead to lumps in your filling.
Prep Ahead & Store
These Cheesecake Peanut Butter Bars can be made ahead of time, making them perfect for busy schedules. Once they have cooled and set, store them in an airtight container in the fridge for up to one week. You can also freeze them for up to three months. Just make sure to wrap them well in plastic wrap and aluminum foil to avoid freezer burn.
Cheesecake Peanut Butter Bars Q&A
Can I use different cookies for the crust?
Absolutely! You can substitute Oreos with any sandwich cookie of your choice, such as chocolate chip cookies or graham crackers for a different flavor profile.
Can I make these bars without peanut butter?
Yes, you can replace the peanut butter with almond butter, cashew butter, or even a nut-free alternative like sunbutter for a similar creamy texture.
How do I know when the cheesecake is done baking?
The cheesecake filling should be set around the edges but slightly jiggly in the center. It will continue to firm up as it cools and chills in the refrigerator.
Can I add toppings to the Cheesecake Peanut Butter Bars?
Definitely! Consider topping them with chocolate ganache, whipped cream, or even a sprinkle of sea salt for an added burst of flavor.
