My obsession with peanut butter and chocolate is no secret.

And ever since I started this blog, I’ve been obsessed with frosting.

See? I told you! Look at that picture of these Reeses Stuffed Brownies. There is about the same amount of frosting as there is brownie in this recipe. And it is peanut butter frosting, which is my favorite frosting ever.

I think my puppy Josie loves peanut butter almost as much as I do. One day last week I found that there was no peanut butter in the closet for my and Josie’s afternoon snack. We just sat down to a devastating snack of Cheerios instead.

Lucky for me, I didn’t have to wait long before we got more peanut butter and made some delicious brownies that literally took 5 ingredients, plus frosting. Brownie mix, cream cheese, butter, an egg, and Reese’s peanut butter cups. The frosting is completely optional, but also completely necessary to me. It makes the brownies look more desirable and also makes them 10 times more decadent, I think. I honestly don’t really care to know what they taste like without frosting!

The frosting that we used for these brownies is the same frosting we’ve used for alot of our peanut butter/chocolate recipes. Yes, I do have it memorized. And trust me, I never get tired of it. When there is left over icing, we will put it in the freezer, and at some point maybe two weeks later we’ll pull it out and eat it in chunks. It’s allowed in our house. My brother and sister can literally smell when someone is pulling out a dessert. I don’t know how they do it- just one minute they’re playing, the next minute they come running upstairs for a lick of peanut butter frosting.

I have one more thing to say before you go and make these brownies (because I know you just can’t resist it)- When you bite into one of these brownies, you will instantly love them. Do you know how I know? Because there are whole Reese’s cups inside of the brownies. You’re welcome.

Reese's peanut butter cups stuffed inside soft, chewy brownies. Top the brownies with this unbelievable peanut butter frosting!
Serves: 16 Bars
  • 1 Pillsbury family size brownie mix (19.5 ounce)
  • 1 egg
  • 4 ounces cream cheese, softened
  • ½ stick (4 tablespoons) butter, softened
  • 16 full-size Reese's peanut butter cups, frozen
  • ½ cup butter, softened
  • 1 cup creamy peanut butter
  • 3 Tbsp. milk
  • 2 cups powdered sugar
  • 2 ounces (2 blocks) chocolate Candiquik
  1. In the bowl of a stand mixer, combine the brownie mix, egg, cream cheese and butter until it is well mixed. Spread the batter in a greased 8x8 pan. Take the frozen Reese's peanut butter cups and press them into the brownie batter in a 4x4 grid pattern. They should be pressed in enough that the top of the Reese's cup is at the same height as the brownie batter.
  2. Bake the brownies at 350 degrees for 28 minutes.
  3. While the brownies are baking, make the peanut butter frosting. Using a stand mixer, blend together peanut butter, powdered sugar, butter, and milk 3-4 minutes or until light and fluffy.
  4. Once the brownies are cool, spread the frosting on top of the brownies. Melt 2 blocks of Candiquik in a microwave safe bowl according to the package directions. Drizzle the melted chocolate on top of the peanut butter frosting and allow the brownies to set.
Make ½ a recipe of peanut butter frosting if you want a thinner frosting layer.

    Those look and sound amazing. Great pics too! Chocolate and PB, are always great! Please come share at the Bacon Time linky, if just started over for the week.

    These bars are completely irresistible to a peanut butter fanatic like me! The soft fluffy topping goes so well with the fudgy brownies underneath! Yum! Pinned.

    Dangerous …. that’s what these brownies are!! I could not be trusted alone with them! 😉 Pinned and I hope to enjoy them SOON!

    • Lizzy T says

      Bradiann- It depends on how fast you’ll eat them! :) These bars will be fine sitting on the cupboard for a couple days. If you want to keep them any longer than that, refrigerate them. Thanks!

    Making these now!! But…do the cream cheese and butter take place of the oil required for the brownie mix? I’m using my favorite ghirardelli brand.

    • Lizzy T says

      Yes, you do not put in any of the ingredients on the back of the brownie box. Just add the cream cheese, egg and butter to the dry brownie mix. Thanks!

  5. Cal says

    Is there any substitute recommended if I don’t have candiquik or do I need to go buy it specifically? Thanks.

    • Lizzy T says

      Cal, instead of candiquik, you can use melted chocolate chips, or a melted Hershey bar…whichever you may have. If you are having a hard time getting the chocolate to drizzle, you could add a bit of shortening to get it more drizzly.

    Unfortunately we found these way, way too rich- the brownies came out with the sweetness and texture of fudge which was overpowering with the Reese’s, frosting, and melted chocolate. . I may try it again making the brownies by the box recipe… Definitely saving the frosting though because that on it’s own was delicious.

    • Lizzy T says

      Yes, this recipe is super rich, and while we love these rich an fudge like, you could definitely make them by the box recipe to have them more cake-like. I’m glad you enjoyed the peanut butter frosting. I can eat that by the spoonful! :)

  7. says

    I made these absolutely delicious creations, but unfortunately did not pay attention to the pictures to see the brownie layer underneath the Reese’s….needless to say my Reese’s are now stuck to the pan! Do you recommend any way i could get the brownies out of my pan without destroying these amazing brownies?? My pan is an aluminum 13 X 8 cake pan..

    I plan on using this Peanut Butter cream on every dessert i make now…THANK YOU

    • Lizzy T says

      Bummer!! I’m not sure how you could remove them. Maybe try placing the pan in a larger pan of hot water to loosen the chocolate? That would be my only thought. Bummer!
      PS. Isn’t the peanut butter frosting amazing? It’s the best!
