Decadent Peanut Butter Oreo Fudge Bars

Peanut Butter Oreo Fudge Bars…. born from a childhood snack that’ll never fade. If you watched The Parent Trap as a little kid and have loved Oreos dipped in peanut butter ever since…. this one is for you. Ever since watching that movie when I was younger, I’ve been obsessed with Oreos and peanut butter. Maybe it’s the simplicity of chocolate and peanut butter together, but maybe it’s something more. The nostalgic and unique flavor of Oreos dipped in creamy peanut butter is just other-worldly. And in the best most incredible way possible.

These decadent peanut butter Oreo fudge bars combine the classic Oreo flavor in an easy crust with a super simple 4 ingredient creamy peanut butter fudge over top. And not to mention, in these bars we use only 5 different ingredients total to bring you one of the best treats. Plus, they are ingredients you probably already have on hand… win-win!

These bars are no-bake and can be thrown together with minimal hands-on time for a crowd pleading treat! They’re perfect for kids who love their Oreos, and for adults who love the nostalgia of peanut butter and Oreos. Long story short, they are perfect for anyone, any age! After all, Oreos never go out of style…

I hope you enjoy these bars as much as we do! Please take a moment to read the tips below so that you get the best results possible. 🙂

Can I use sandwich cookies other than Oreos?

Sure! Use whatever chocolate sandwich cookies you like! I love Oreos, but I also love this brand as well. 🙂

Do I need to remove the creme filling?

YES. YES YES YES. This is a crucial step and using the filling will not give you the right texture on the crust!

What if I don’t own a food processor?

That’s ok! I highly recommend one for this recipe but if you don’t have one, I have a solution for you. 🙂 Simply put the Oreo cookies in a ziplock (or similar) bag, remove the air, and with a rolling pin or similar vessel, crush the cookies to a very fine consistency.

How long do I leave the Oreo crust layer in the fridge?

Before putting the fudge layer over top, you’ll need to refrigerate the crust. This helps it solidify, but also helps when spreading the fudge over top! AT LEAST an hour in the fridge for the Oreo crust layer, but the longer the better. 🙂

Ingredients

  • Oreo Crust
  • 3 Cups Oreo Cookies, without the filling (about 1 package of Oreos)

  • 1/2 Cup Unsalted Butter, melted

  • Peanut Butter Fudge
  • 1 Cup Unsalted Creamy Peanut Butter

  • 1/2 Cup Butter

  • 1 Tbsp Vanilla Extract

  • 1 Cup Powdered Sugar

Directions

  • Oreo Crust Layer
  • Begin by preparing the Oreo crust. First, open each Oreo and remove the filling from each cookie. Add each cookie to a bowl until you’ve removed the creme from each Oreo. You can discard the Oreo creme filling.
  • Add all cookies to a food processor and process until they are a fine consistency. Make sure to start and stop your food processor a couple of times and move the Oreo cookie pieces around to ensure they all become processed to a fine consistency.
  • Once you’ve processed the Oreos, measure out 3 cups of the crushed Oreos. Add them to a large mixing bowl and pour the melted butter (1/2 cup) over top. Mix together until the Oreos and butter are well combined.
  • Then, line an 8×8 pan with parchment paper (this is super important in order to pull the bars out). Add the Oreo crust to the parchment-lined pan and press it into one even, flat layer. I like to use an offset spatula or the flat side of a measuring cup to do this. It’s important to press down and compact the Oreo crust in this step!
  • Place this layer in the refrigerator for at least 1 hour while you make the peanut butter fudge layer.
  • Peanut Butter Fudge Layer
  • To a medium saucepan, add the butter, peanut butter & vanilla. Melt over low – medium heat until fully melted. While heating the butter, peanut butter, and vanilla, lightly stir continuously to combine.
  • Once melted and combined, remove the saucepan from the heat and add in the powdered sugar, about half at a time. With a whisk, mix the powdered sugar into the peanut butter mixture until you’ve added the full cup of powdered sugar, and it has fully combined with the peanut butter and butter.
  • Let the fudge cool slightly and then remove the Oreo crust layer from the refrigerator. Pour the peanut butter fudge mixture over top of the Oreo layer and spread it out into another even layer.
  • Place the layered Oreo crust and peanut butter fudge back into the fridge for another 90 minutes until the fudge has solidified.
  • At this point, you can slice your Peanut Butter Oreo Fudge bars and enjoy!

Notes

  • Store in the refrigerator for up to a week. Past one week, cut & freeze the bars.

    This recipe is phenomenal. It is not overly heavy/overly sweet at all. Everyone I have showed it too has fallen in love with it. My sister took a bite and simply said “oh my gosh you could sell this for money”. And I wish I could take credit for the recipe. But sincerely delicious! Can’t wait to try more from this page!

    I used the Oreo cream to make frosting. I added some powdered sugar and milk to it until it was a spreadable consistency. Iced some chocolate cupcakes with it and sprinkled them with crushed Oreo cookies.

I live and die by breakfast food, coffee, peanut butter, and dessert. It's pretty much my blood type at this point.
