Peanut Butter Oreo Cheesecake Bars Recipe — Creamy No-Bake Treat

Peanut butter and Oreos are a classic combination, and these Peanut Butter Oreo Cheesecake Bars capture that pairing perfectly. The recipe starts with a dense Oreo crust, followed by a creamy peanut butter cheesecake filling studded with chopped Oreos. Once baked and chilled, the bars are finished with a optional chocolate ganache drizzle and extra crushed cookies for texture. They’re indulgent, easy to make, and ideal for sharing—or keeping all to yourself.

The bars are rich but straightforward: no eggs and no water bath are required, which simplifies the process compared with many traditional cheesecakes. If you need a gluten-free version, swap in gluten-free Oreos and a suitable flour substitute. Otherwise, the standard ingredients deliver a deliciously balanced dessert that’s creamy, slightly salty from the peanut butter, and full of Oreo crunch.

Ingredients for Peanut Butter Oreo Cheesecake Bars

Here’s what you’ll need to make these bars.

• Oreos
• Unsalted butter, melted
• Cream cheese, room temperature
• Granulated sugar
• Peanut butter
• Milk, room temperature
• All-purpose flour
• Vanilla extract

What Type of Peanut Butter Should I Use?

Both natural and regular (conventional) peanut butter work well in this recipe. Natural peanut butter usually has no added sugar and needs stirring, giving a slightly tangier, less sweet result. Conventional brands like Skippy or Jif include added sugar and oils, producing a sweeter, creamier filling. I tested both and found each delicious; I ultimately used natural peanut butter because the overall dessert was already rich and sweet enough from the Oreos and sugar.

Either option is fine—choose according to how sweet or intensely peanut-flavored you want the final bars to be.

Tips for the Best Peanut Butter Oreo Cheesecake Bars

• Room temperature ingredients: Make sure the cream cheese and any dairy are at room temperature before mixing. This prevents lumps and yields a silky filling.
• Cool completely before cutting: Let the bars cool to room temperature, then chill thoroughly in the refrigerator. Chilling helps the bars set and makes clean slicing much easier. These keep well overnight—making them great for preparing ahead.
• Optional ganache: A chocolate ganache drizzle adds a glossy finish and extra chocolate flavor. It also helps hide any minor cracks on the surface. You can drizzle it lightly or pour a thin layer over the chilled cheesecake and let it set for a fudgier top.

If you love the peanut butter and Oreo combo, these bars are a must-try. They’re creamy, satisfyingly chocolatey, and simple enough for a weeknight bake or a special occasion dessert. Happy baking!
