PEANUT BUTTER OREO BARS
Rich and creamy bars, like Peanut Butter Oreo Bars, are perfect for a simple treat, or dessert to bring to a party. Kids and adults alike will love the sweet chocolate, creamy peanut butter, and crunchy Oreo crust. They’re wonderfully sweet with a nice saltiness from the peanut butter. Bar recipes are always great for a crowd because they’re made in big batches. For another no-bake bar recipe try Chocolate Marshmallow Peanut Butter Bars.
If you do bring this dessert to a party, make sure you don’t take it out of the fridge until you have to. The peanut butter filling and chocolate topping are best served chilled. Otherwise they become melty and sticky. If you know they’ll be left out at the party for a while, try keeping them in your freezer beforehand so they start out colder.
You’ll be glad you did, when you try the cool and refreshing chocolate treat. The most difficult part of this whole recipe is finding the patience to wait for them to harden in the fridge before eating them.
HOW TO MAKE THE LAYERS
- Oreo Crumb Crust: add 14 Oreos to your food processor and blend until they’re in fine crumbs. Mix the oreo crumbs with 2 tablespoons of melted butter, and press the mixture into an even layer along the bottom of your baking dish. Freeze for 10 minutes until hardened.
- Peanut Butter Layer: Add 1 cup melted butter, 2 cups of graham cracker crumbs, and 1 cup of peanut butter to the stand mixer. Mix all the ingredients until combined. Add in 2 cups of powdered sugar with the mixer on its lowest speed. Keep mixing until well combined and fluffy. Use a spatula to spread the peanut butter filling over the oreo crust. Once spread out evenly return the pan to the freezer.
- Chocolate Layer: Put a medium-sized saucepan over medium heat. Add in 4 tablespoons of peanut butter and 1 1/2 cups of semisweet chocolate chips. Stir the mixture continuously until melted and creamy. Remove the bars from the fridge and pour the chocolate topping over it. Tilt the pan to get the melted chocolate to spread. Return the completed bars to the fridge for 2 hours before serving.

Other than that, this recipe is so easy it’s a great one to let your kids help out with. The only part you need the stove for is the chocolate topping, so depending on how young your kids are you can just handle that yourself.
If you let your kids help, you do risk some of the Oreos and chocolate chips never making it into the Peanut Butter Oreo Bars. So, just make sure to have some extra on hand. Honestly, snacking on the ingredients is part of the fun of this dessert anyway.

VARIATIONS ON PEANUT BUTTER OREO BARS
- Graham Cracker Crust: Don’t have Oreos? no worries! Instead of using Oreos in the crust, you can use graham cracker crumbs. Blend them up the same way you would Oreos and combine the crumbs with butter. To keep it chocolate, use chocolate graham crackers.
- Crunchy Peanut Butter: For some extra crunch in your Peanut Butter Oreo Bars, try using your favorite crunchy peanut butter in the filling. If you have creamy peanut butter, you could also mix whole peanuts into the mixture yourself.
- Chocolate Chips: Change up the taste of your chocolate topping depending on what chocolate chips you use. Instead of semisweet chocolate chips try out milk chocolate, dark chocolate, or even white chocolate chips.
- Toppings: For toppings try adding crushed peanuts or coarse sea salt over the top of your Chocolate Peanut Butter Bars. Sprinkle the toppings over the melted chocolate before you put the bars in the fridge.

I love sweets and often find myself having a few servings in one sitting but this dessert was SO incredibly sweet and rich that I couldn’t even finish the small square I cut out. I figured the peanut butter layer would be pretty sweet due to the 2 cups of powered sugar and while I wanted to add less I figured I’d better stick to the recipe in case this was the magical amount to balance everything together. Aside from it being way too sweet, the pan size was too small. I followed the recipe and my bars came out way thicker than what the photo on here shows. The peanut butter layer almost seemed twice as thick.
I just got done retesting this recipe and have made some adjustments based on your concerns. Thank you so much for giving me the feedback. I’m so sorry that you had issues.
Oh I cannot wait to try this. Looks amazing!
I hope you enjoy them.
So rich! Delicious. I’m going to need a glass of milk or a cup of coffee with this…maybe both!
Not a bad idea, Betsy.
Best bar ever! My two favorites in one dessert! ?
I’m glad you enjoyed it. Thanks for the 5 stars, Melissa.
OMG these are amaizing! My entire family loved them of course. My only complaint, and question, is that the bottom layer did not hold up when cutting them from the pan. I did as the recipe instructed but the oreo crumbs were really dry even with the 2 tbsp of melted butter. Does that mean more butter should be added or does it need to sit in the freezer longer then the 10 minutes?
I went through and made some adjustments after retesting so that should resolve any issues you might have had. Thanks so much for the feedback.
