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.

Reeses Stuffed Brownies

Reese's peanut butter cups stuffed inside soft, chewy brownies. Top the brownies with this unbelievable peanut butter frosting!


  • 1 Pillsbury family size brownie mix (19.5 ounce)
  • 1 egg
  • 4 ounces cream cheese, softened
  • 1/2 stick (4 tablespoons) butter, softened
  • 16 full-size Reese's peanut butter cups, frozen
  • Frosting:
  • 1/2 cup butter, softened
  • 1 cup creamy peanut butter
  • 3 Tbsp. milk
  • 2 cups powdered sugar
  • 2 ounces (2 blocks) chocolate Candiquik


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.

Bake the brownies at 350 degrees for 28 minutes.

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.

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 1/2 a recipe of peanut butter frosting if you want a thinner frosting layer.

  14. Do these need to be refrigerated?

    • 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!

  15. I just found your blog and I’m already in love! In fact, I spent all of my exercise time browsing through it! These look delish!

  16. Jessica says:

    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!

  17. 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.
