Two layers of peanut butter cups in these brownies – one layer is baked into the brownies and the other is the peanut butter and chocolate chip topping. These peanut butter cup brownies are insanely tasty and so easy to make!

You know those thick-frosted brownies you see at bakeries? Those have nothing on these. Layering peanut-butter cup fudge on top of brownies that have peanut butter cups inside of them is about a million times better than frosting.

And I l.o.v.e. frosting. But peanut butter cups? And a thick layer of pretty much pure chocolate and peanut butter? Yeah, I’m fine to set aside the spoon filled with frosting. At least for a minute…

I tried to illustrate the peanut butter swirling in the collage above, so hopefully that helps. Pretty much you just pour the peanut butter in strips over the chocolate and press the knife through the peanut butter and chocolate layer pulling it from one side to the next. I like the clean off the knife in between each stripe I make to keep it as “clean” looking as possible.

You’ll want to let the chocolate and peanut butter topping harden completely before cutting into these. It takes a few hours, but that can be sped up by placing them in the fridge,

You can store these in the fridge, but I like them at room temperature. The chocolate and peanut butter are perfect at that temperature and taste just like fudge. And I promise, you are going to want a huge glass of milk with these rich peanut butter cup brownies!

  • 1 package fudge brownie mix (18.3 ounces or Family-Size for 9 x 13 pan)
  • Ingredients called for on the brownie mix
  • 12 regular-sized Reese's peanut butter cups
  • 2 and 1/2 cups milk chocolate chips
  • 3/4 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 2 and 1/2 tablespoons shortening or coconut oil, separated


  • Line a 9 x 13 pan with parchment paper and set aside. Preheat the oven to 350 degrees F.
  • Prepare the brownies according to package directions. Pour the mixture into the prepared pan. Bake for 22 minutes and then remove.
  • Press the unwrapped peanut butter cups evenly into the brownies.
  • Return the brownies to the oven and bake for another 5-6 minutes or until a fork when inserted into the brownies comes out clean. (Follow general package directions for baking, but remove them about 5 minutes before they are done to add the peanut butter cups.)
  • Remove and allow to cool.
  • In a microwave safe bowl, combine the chocolate chips and 2 tablespoons of shortening or coconut oil. Microwave in bursts of 30 seconds stirring in between the bursts until the chocolate is completely melted.
  • Smooth the chocolate over the brownies evenly.
  • In another small microwave safe bowl, combine the peanut butter and remaining 1/2 tablespoon coconut oil or shortening. Microwave for 30 seconds.
  • Remove and stir in the vanilla.
  • Pour in long stripes over the chocolate. Using a butter knife marble the top by running the knife horizontally from left to right just through the top chocolate and peanut butter layers.
  • Allow to completely harden before enjoying the bars.

  1. Any brownie that you could eat with a fork is a sure winner in my book, Chelsea! It just means they’re super fudgy and delicious! 🙂 I’m so loving all of the peanut butter flavors in here. So great for a peanut butter fanatic like myself. Can’t wait to try this out! Pinned!

  2. You can never beat peanut butter and chocolate together! I’m currently wiping drool off my iPad while salivating over your gorgeous pictures!

  3. Chelsea, you are KILLING me with these gorgeous, gorgeous things! This looks like the best kind of #wifeanniversearyfail ever though–my husband is also a plain jane brownie man but you have to appreciate the gobs of PB here. Because it is perfection.

  4. These look so yummy, tho I can’t have p-nut stuf I can sub that for sun nut, I’m going to try them! Can’t wait to get right on that, =)

  5. These are the prettiest brownies I’ve ever seen. 🙂 Reese’s are my favorite! I love how you added them to the partially cooked brownies. I wouldn’t have thought of that! Those stripes of peanut butter look perfect!

  6. these are amazing! Always looking for treats to send to deployed soldiers, as their # request is BROWNIES. Just wondering if you have ever FROZEN these, then run them through a food-saver….wonder if these would be good to ship during cooler weather months! Thanks…. & a agree about Box Brownies vs. Homemade!

  7. So funny, I was looking for something quick and easy and special for our anniversary dessert since we weren’t going anywhere when I came across these. I knew my husband would go nuts for them because he likes rich desserts and I like to surprise him with something new. I didn’t have the REESE’S but had everything else so what the heck. They turned out great and he has been enjoying them. Thanks for sharing.

    TWO WORDS: Keeper Recipe! Made these for family, friends, & coworkers and they are always a hit!! People beg for the recipe! DELISH!!!!!!! Slap yo grandma good! THANKS for the deliciousness:)

      1. I just made these and accidentally forgot the vanilla in the peanut butter, does is really make a difference

  9. Oh my gosh! I’m in charge of bringing a brownie dessert to a ladies luncheon this Saturday and I think I just found the perfect one! I love, love, love peanut butter cups and your photos are making me drool. Hope mine look as pretty as yours. Thanks for sharing!

  10. hi, do you think it possible to bake this cake but without the peanut butter cup?
    i can’t find those in France 🙁
    Thanks a lot, look delicious.

  11.

    I have a question Chelsea…the brownie mixes we buy here are for a 8×8 inch pan…would you use 2 of them for the 9×13?
    I can’t wait to try these ..they look scrumptious!

  13. Hello, these look amazing. I don’t have chocolate chips but have lots of Hershey’s kisses. If I chop those up do you think they will be okay to substitute for the chocolate chips!

  14. Hi Chelsea, , I abhor boxed mixes with the exception of brownies. Somehow they are so much better than homemade. Ghirardelli is my favorite. I heard that America’s Test Kitchen/Cook’s Illustrated has come up with a homemade recipe to rival the box, but I haven’t seen it. I can’t wait to try all your PB/Chocolate desserts. Thank you. And phooey on husbands. The only thing mine likes is plain cheesecake with a berry topping.

    1. Hey Brisa! I 100% agree!! I think I’ve tried no short of 30 brownie recipes and none are as good as the mix for me! I need to try and find that ATK brownie recipe and try that out sometime 🙂 I hope you love the PB/Chocolate desserts, they are my favorite to create (and eat!) HAHA! I think our husbands would be friends, he loves plain cheesecake with berries too 🙂 Thanks for your comment!!

    Tried these and OMG, they were absolutely delicious! If I could I would give them 10 stars, I would! I could only eat half of a half, they are so rich! Best brownie recipe ever! Trying to figure out the nutritional value as I am trying to watch my weight, but even the small amount I had was awesome! LOL Husband and kids LOVED them. Will definitely be a go to recipe in the future! Thanks!

    1. What a compliment!! I’m seriously thrilled these were such a huge hit! And, I’ve added the nutrition information right below the recipe. Thanks for the comment Denise 🙂

Guaranteed to be a favourite with any peanut butter lovers like me! Thanks so much for this recipe, one of my all time favourites and I will definitely be making them again.. sadly they didn’t last long around my family!
