Easy Buckeye Cookies Made with Brownie Mix!

It’s hardly a secret around here that I’m a little obsessed with chocolate and peanut butter. Name a better sweet-salty-creamy combination! Oh wait, you can’t. 

Recently I had a craving of epic proportions for something chocolatey and delicious. So I did what any reasonable peanut butter and chocolate addict would do. Taking inspiration from my Buckeye Brownies, I doctored up a box brownie mix and finagled these sweet and chewy Buckeye Brownie Cookies!

These easy brownie cookies (“brookies”) are stuffed with a peanut butter ball and topped with chocolate frosting. They might look a bit unassuming at first glance. But on the inside, they’re pretty magical!

What Are Buckeye Cookies?

In case you’ve never had buckeyes before, they’re a classic no-bake treat made with balls of sugary peanut butter fudge dipped in chocolate (a bit like Peanut Butter Balls!). A circle of peanut butter is left uncovered, which makes buckeyes look a bit like the nuts from an Ohio buckeye tree, named after the eye of a deer!

So, Buckeye Cookies are the baked best of both worlds: a rich chocolatey cookie wrapped around a sugary peanut butter center! I top mine with a layer of chocolate frosting, too, since I can never pass up an opportunity for buttercream.

Recipe Ingredients

Less than 10 ingredients is all you need for these delicious buckeye brownie cookies!

  • Brownie Mix: Your preferred boxed brownie mix. You can use any type of chocolate brownie you’d like!
  • Butter: Salted or unsalted, and melted.
  • Cream Cheese: Let your cream cheese come to room temperature before you start. It’s much easier to mix in this way!
  • Peanut Butter: I recommend using a good quality, shelf-stable creamy peanut butter, and not the natural kind (more on this below).
  • Egg
  • Powdered Sugar
  • Chocolate Frosting: I used my favorite recipe for homemade chocolate frosting, but you could also use canned frosting for convenience.

What Kind of Peanut Butter is Best?

For best results with these cookies, I suggest using your favorite brand of creamy or smooth peanut butter. Brands like Jif or Skippy are my go-tos. Avoid natural peanut butters as these tend to have more oil and don’t bake up well.

I’ve never made these cookies with crunchy peanut butter, but I’d imagine they just wouldn’t be the same without that fudgy smooth filling! So definitely stick to classic smooth peanut butter, if you can.

How to Make Buckeye Brownie Cookies

This cookie recipe is so easy to make. Here’s what you do:

Make the Brownie Dough: Mix up a box of brownie mix with the cream cheese, melted butter, and an egg. The texture will be sticky and thick – I actually used my hands to mix it together.

Roll the Dough: Form the brownie dough into balls and place these on a baking sheet lined with parchment paper. Use your thumb to make an indentation in the top of each dough ball.

Make the Peanut Butter Balls: Next, mix the peanut butter and powdered sugar. Roll the peanut butter mixture into small balls and press those into the indents in the brownie dough.

Bake: Bake the buckeye cookies in a 350ºF oven until the edges are set. These cookies don’t spread very much at all, so they’ll look about the same before and after baking.

Frost: Move the baked cookies to a wire rack. Once they’re cool, I like to spread some chocolate frosting on top and give them a sprinkle with flaked sea salt. Here’s my recipe for Easy Fudge Frosting!

Tips for Success

  • Don’t Overbake: These cookies will look almost the same coming out of the oven as they did going in! So be mindful to not leave them in too long, even if they don’t seem especially done. Overbaking will lead to crunchy, crumbly cookies.
  • If Your Peanut Butter Filling is Thin: If your peanut butter fudge filling seems a little on the thin and sticky side, add a bit more powdered sugar until you get the right consistency.

Storage Instructions

Keep these buckeye brownie cookies stored airtight on the counter for up to one week. You can also keep them in the fridge if you prefer, but I find the texture is just so much better at room temperature!

Do These Freeze Well?

The unfrosted cookies are a cinch to freeze. You can make a batch ahead and then store them in an airtight, freezer-safe container or freezer bag for up to two months. Thaw the frozen cookies on the countertop so that they can come to room temperature again, and then frost them as usual.

Description

A classic homemade candy gets a fresh take in these Buckeye Brownie Cookies! Easy chocolate brownie mix cookies are baked around rich peanut butter fudge centers.


Ingredients

Scale
  • 1 box (18-19 oz) Brownie mix
  • 1/4 cup butter, melted
  • 1/2 cup cream cheese, room temperature
  • 1 egg
  • 3/4 cup peanut butter
  • 3/4 cup powdered sugar
  • 3/4 cup chocolate frosting


Instructions

  1. Preheat oven to 350°
  2. Line baking sheet with parchment paper.
  3. In a medium bowl combine brownie mix, butter, cream cheese and egg. Stir until dough comes together, it will be very thick and sticky. I used my hands.
  4. Form rounded tablespoons sized portions of dough into balls, placing on baking sheet about 2 inches apart, making an indentation with your thumb in the center of each.
  5. In another bowl stir together peanut butter and powdered sugar. Form peanut butter into teaspoon sized balls and press into the indentations in the brownie cookies.
  6. Press peanut butter down slightly because the peanut butter won’t spread and you don’t want the cookies to be too tall.
  7. Bake for 10-12 minutes until edges are set.
  8. Transfer to wire rack to cool.
  9. When cooled top each cookie with about a tablespoon of chocolate frosting.

Notes

I used my recipe for chocolate frosting, but you could also use canned frosting.

  1. Oh how I laughed at the image of you stalking the intruder. I need these. Now. I am a peanut butter ball lover (uh, not buckeyes here, but I shall forgive you your transgressions), and brownie cookies call my name. I guess I know what I’m doing with the peanut butter I just bought last weekend now.

  2. Brilliant. I definitely will try these and share with my friend from Ohio who makes Buckeyes every Christmas. Great idea!

  3. i started making 1 batch & it didn’t seem like enough, so i grabbed another box of brownie mix to make a 2nd batch, but the 2nd batch was even gooey-er than the 1st… i thought i had done something wrong, turns out 1st batch was basic brownie mix, 2nd batch was ‘fudge’ brownie mix – oy!!!

  4. OMGosh these sound so wonderful ……I love your recipes ….and I use them with my seniors all the time and they Love it Thanks for giving me great resources and make the seniors I work with have good recipes to still share with their daughters. Linda @ Activity Directors Sharing Ideas on Facebook ……see the wonderful stuff we have been doing with your recipes =)

  5. As a native Buckeye, I am going to make these as I watch my team win their final FOUR game tonight AND onto the championship!!!! (keeping my fingers crossed)

    I’m right there with you — I would either go toward to noise and be killed or form a puddle as I melt with fear, and be killed. Either way, unless my kids were in danger, I wouldn’t be much help. Glad you can laugh about it now (after your knees stop shaking.) LOVE your recipes and blog!

  6. I’m glad you lived through the attack of the ipod so you could give us this recipe. It’s the perfect recipe for my husband and I. He loves peanut butter and I love chocolate. And it’s got just enough of the peanut butter to keep me from eating all of them.

    Okay…I don’t know much, but if you’ve ever ever ever taken any advice from me, take this. NEVER EVER EVER walk toward the noise. Make your husband do it, LOL! These look wonderful!

    Welp, obviously I’m making these this weekend. I sometimes think there isn’t any possible peanut butter and chocolate recipes I haven’t discovered and then the internet proves me wrong.
