- Frozen Whipped Topping – This helps add volume to the filling, making it extra sweet and fluffy!

Variations
This peanut butter bar recipe is super rich and tasty on its own. However, feel free to make swaps, additions, or substitutes to make it your own!
Swap Out the Crust. Feel free to experiment with different Oreo flavors or items like Nutter Butters or graham crackers to form the base of the peanut butter bars.

How to Make The Best Oreo Peanut Butter Bars Recipe
With just 10 minutes of baking time required, these peanut butter bars are nearly a no-bake recipe! Here’s how they come together.
- Create the Crust. Add the Oreos and butter into the bowl of a food processor, and pulse until fine crumbs are formed. Press the mixture into the bottom of an aluminum foil-lined baking dish, and bake until the mixture has set.
- Create the Peanut Butter Filling. In a stand mixer or large bowl, cream the cream cheese, powdered sugar, and peanut butter together until the mixture is smooth and fluffy. Add the vanilla and whipped topping, and beat again. Gently fold ½ of the Oreo pieces into the mix, and spoon it evenly over the prepared crust.
- Make the Ganache Topping. Warm the heavy cream in the microwave until it begins to simmer. Add the chocolate chips. Once melted, use a whisk to stir until the ingredients are well combined. Pour the mixture over the peanut butter layer of the bars. Sprinkle more Oreos on top.
- Freeze. Place the peanut butter bars in the freezer for up to 1 hour or in the fridge for 2-3 hours to set. Slice the dessert into bars, and enjoy!
Pro-Tips
This recipe is pretty failproof. However, there are a few crucial tips that will ensure they turn out well every time you make them!
Use the Right Size Baking Dish. You’ll want to make sure you’re using a 9×9” baking dish for super thick bars.
Don’t Forget the Foil or
Avoid Oily Peanut Butter. You’ll want a classic smooth, creamy peanut butter like Jif or Skippy. All natural varieties that are super oily will not combine well and could cause your bars to separate.
Use a Sharp Knife. Make sure to use an extra sharp or serrated knife to cut your bars smoothly, running it under water and wiping it clean after each slice.

Sure! Transfer them to an airtight container or wrap them in plastic wrap and aluminum foil, and freeze them for 3-4 months. Then, just let them thaw at room temperature on the counter when you’re ready to eat.
