Why You’ll Love These Oreo Peanut Butter Bars

Oreos and peanut butter are two of our favorite foods in the entire world. So, we’ll take any excuse to combine them into one treat, and this peanut butter bars recipe does not disappoint! Here are just a few reasons why we love it so much: 

  • It’s made with 8 ingredients.
  • The bars are quick and easy to whip up with minimal baking.
  • You can prepare it ahead of time for special occasions. 
  • They’re indulgent and irresistible

Ingredients You’ll Need

Part no-bake recipe, part cheesecake, fully delicious, the ingredients needed for this peanut butter bars recipe are super simple! 

  • Oreos – We use regular chocolate Oreos to form the crust and sprinkle broken cookies into the bars for added flavor and crunch. 
  • Butter – This combines with the Oreo crumbs to create a smooth, rich crust.
  • Cream Cheese – Full-fat cream cheese helps add structure to the peanut butter filling, making it extra creamy. 
  • Peanut Butter – We recommend using creamy peanut butter for easy mixing! 
  • Powdered Sugar – Used to sweeten the filling.
  • Vanilla – Helps enhance the flavor of the rest of the ingredients. 
  • Frozen Whipped Topping – This helps add volume to the filling, making it extra sweet and fluffy! 
  • Chocolate Chips – We prefer to use semi-sweet chocolate chips, but dark chocolate would taste great, too. 
  • Heavy Cream – Used to form the base of the ganache. 

Variations

This peanut butter bars 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. 

Use a Different Nut Butter. If you can’t eat peanuts, feel free to use any other nut or seed butter like almond butter, cashew butter, or sunflower seed butter instead. 

Add Extra Mix-Ins and Toppings. Take your peanut butter bars recipe up a notch by replacing or adding to the Oreo pieces with chocolate chips, chopped nuts, M&M’s, and more!

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. 

  1. 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. 
  2. 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. 
  3. 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.
  4. 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 Parchment Paper! Without it, your bars will stick to the pan and separate and fall apart once sliced. 

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.

Peanut Butter Bars Common Questions

Can I make this peanut butter bars recipe in advance? 

Yes! In fact, we recommend it. To prepare in advance, assemble your peanut butter bars as instructed, and set them in the fridge for up to 1 day. 

How long does this recipe last? 

Stored in an airtight container or wrapped in aluminum foil or plastic wrap, these bars will stay fresh in the refrigerator for 5-7 days. 

Can I freeze leftover peanut butter bars? 

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. 

Can I use a pre-made crust? 

We have found that creating your own Oreo crust results in the best taste. However, if you want to save time, you can definitely use a pre-made version from the store instead.
