Buckeye Brownies

Buckeye brownies are an easy brownie recipe filled with creamy peanut butter.

These Buckeye Brownies are an easy chocolate and peanut butter brownie recipe based on the popular midwest candy called Buckeye Balls aka Peanut Butter Balls.

Buckeye Brownies are an Easy Chocolate and Peanut Butter Brownie Recipe!

If there was ever a brownie recipe that got a standing ovation, this might be it. Combining peanut butter and chocolate tends to do that to people. I mean, it isn’t a classic flavor combo for nothing…and this is coming from a girl who just ate a spoonful of peanut butter with chocolate chips on it for an afternoon sweet treat. I mean I am kinda-sorta known for some pretty epic chocolate-peanut butter desserts like Peanut Butter Balls, Buckeye Brownie Cookies, and Peanut Butter Cup Brownie Cheesecake to name a few!

This Buckeye Brownie Recipe is chewy and fudgy with sweet peanut butter filling

What Are Buckeyes?

Buckeyes are popular in Ohio, as the Buckeye is the state tree! This brownie recipe is a spin on Buckeye Balls which are peanut butter balls that are only partially dipped in chocolate, leaving the peanut butter showing on the top. That way they look like the nuts from a Buckeye tree.

So long story short, this brownie recipe is just a fun spin on Buckeye Candy turning them into a rich, chewy, fudgy peanut butter and chocolate brownie!

How To Make Buckeye Brownies

How Do You Make Buckeye Brownies?

I started this recipe with a boxed brownie mix to make things easy. You could certainly use a brownie recipe from scratch if you prefer, just make sure the recipe is supposed to be baked in a 9×13 pan and the batter is on the thick side so you have enough brownie batter to hold the peanut butter filling.

  1. Once you’ve made your brownie batter, stir in some chopped peanuts to give a little extra crunch. You can leave the chopped peanuts out if you don’t like nuts in your brownies, no problem!
  2. Then mix together some peanut butter and sweetened condensed milk. This makes a magic peanut butter filling.
  3. Press half the brownie batter into a greased 9×13 pan, and then pour the peanut butter filling on top of that! Drop the remaining brownie batter onto the filling and lightly press it in. When these bake they will look pretty and marbled on top!
  4. Bake them for about 25 minutes until the edges are set, and then let them cool!

Can You Freeze These Brownies?

Yes, absolutely! Buckeye Brownies can easily be frozen. Let them cool completely, and you can freeze them in the pan, or cut them into bars and freeze them like that. Just make sure they are airtight and they will be great for up to a month! Let them thaw out at room temperature for eating.

  • If you freeze them in bars, just place them in a flat layer in a zip-top bag, with a piece of parchment paper separating the stacks. Or you can also freeze them in a large plastic container.
  • If you choose to freeze them in the pan, allow them to cool and cover the pan in foil. Cut them after they have thawed out!

Buckeye Brownies are the Perfect Brownie Recipe for Peanut Butter Lovers!

These brownies come together so quickly, but are really a showstopper! The thick peanut butter filling sandwiched in between the two brownie layers is sweet and creamy. And like I said before, you can absolutely omit the chopped peanuts if you don’t want any crunch.

  1. Sometimes I welcome a Monday off – so glad this was a short week for us. My family is from the east coast area and they didn’t know what a buckeye was – even though my sister brought them to our family gatherings. She just called them chocolate covered peanut butter balls. We told her they were buckeyes and why. I like your brownies.

    I too could easily swim in the sweetened condensed milk/PB mixture for days on end! So yummy! And again, love your blog!

  3. Kristina

    I just found your blog a week or so ago. Which happened to coincide perfectly with the beginning of my 3rd trimester… I’m expecting some rapid weight gain over the next few weeks, courtesy of your deliciousness.

    And on another note, I may or may not have double layered blackout curtains hanging in my kids’ rooms. ๐Ÿ™‚

  4. Looks fabulous and I too could swim in peanut butter and sweetened condensed milk. No question.

    I saw Kristi’s post about the Duncan trip and I told her that one day I’d love to meet both of you two!

  5. dawne

    wish i had seen this a half hour ago i just made brownies and dropped big globs of chunky peanut butter all over. yummy ๐Ÿ™‚

  6. Victoria

    These look wonderful!!! And it sounds like your on Team Damon. ๐Ÿ˜€ Now if I could just have him handing me a plate of these….

  7. Oh Shelly, You are so funny! I was laughing out loud at your daylight savings segment, and I just had to share it with my husband:)
    Your brownies look phenomenal!!!

  8. Great seeing you this weekend. ๐Ÿ™‚ Have to laugh given the conversation we had on the shuttle with Toni about making something and then seeing someone else just made it – totally made Buckeye Brownies on Thursday. Though I’m going to have to try some with the sweetened condensed milk. It’s like nectar of the Gods.

  9. Great post! I do agree that it’s a nightmare trying the get the kids to bed when it’s still light outside..I’ve had many stressful evenings lately! These brownies just might save me!

  10. Ugh, I hear you on Daylight Savings. My kiddo makes a pretty good argument about not being able to sleep when the sun is still shining into his bedroom. But oh my goodness, these brownies are amazing! Anything with sweetened condensed milk in it is a must-make!

  11. Seriously, I could eat the whole pan of these right now – and I agree, sweetened condensed milk makes everything better. I think I’d have a cup of coffee w/ the condensed milk with these brownies.
    Thanks for sharing.

  12. Those look crazy good!
    I just started watching the “TV Show” on netflix as well, and I’m really not sure what to think. I’m up to episode 7 or 8 and for some reason I can’t seem to turn the stupid show off. It’s great background noise while I’m baking because even if I’m not paying attention, I still know what’s going on.

  13. Just found your blog and I love your style, your photography, and certainly your taste in food. If it’s got sweetened condensed milk in it, I’m good to go! These brownies look SO yummy that I will have to bake them soon… maybe have them ready when my hubby gets home from work?

  14. 1 more week after this week and then I am off for the Summer. I cannot wait! Perhaps a pan of these buckeye brownies will help me study for finals? They look delicious and, heck, I could use all the help I can get for my finals!

  15. Um, yep. Those look beyond heavenly! As for the whole “Daylight Savings before school ending” thing, I’m totally with you. I’ve considered putting those little airline sleeping masks on my children to fool them into thinking it’s 10pm.

  16. Well, that looks like the single best thing I’ve ever seen in my entire life. I need to find a way to incorporate nutella into this, and then I’ll REALLY be in heaven. Not in place of the PB, of course, but in addition to. Hello, hallelujah.

  17. DynaLou

    This is why I really love experimenting and looking for sites with recipes.. I just want to make sure this is what my kids would love too after I bake one like this.. Craving for brownies now!

  18. Mmm I’m not a huge fan of peanuts on my brownies, but they’re basically the only nut my boyfriend eats so I’m sure I’ll give this recipe a good use.
    And daylight savings time sounds so annoying, I’m glad we don’t have it here ๐Ÿ˜›

  19. Is anything better than PB&C. I love that combo and use it all the time. Buckeye seems to be popping up in everything now: candies, cookies, cupcakes, cakes, and more, and I’m not complaining!

  20. Chucky

    Brownies are favorite of my girls and my wife is always baking brownies almost every weekend so that my kids will be excited to have a boning together..

  21. I love buckeyes! My Ohio-native hubby got me hooked on them (although I use SunButter in mine because of my allergy, which he hates lol). These brownies look amazing!!

  22. My 13 y.o. STILL goes to bed at 8:30. Mama needs some alone time….well, and maybe some quality time with the husband. Since my bedtime is 9, I need that 30 minutes. ๐Ÿ˜‰

    These brownies look IN-credible, Shelly! Are you sure you can’t move back to Texas? The house next door to us is for sale and I’ll happily be your taste-tester.

  23. So a friend send me over with rumors of chocolate sex. Well…buckeye brownies and Damon…same thing. Looks delish! I’ll be sticking around to see what other sinful things you post ๐Ÿ™‚

  24. I made these yesterday for a family gathering and they were a HUGE hit. Thanks for sharing this recipe. I will definitely be making it again. I didn’t have any peanuts, so I omitted them, but I cannot wait to add them next time.

  25. Betty

    Made these for the weekend! They were awesome and gone in less than 24 hours. Everything that I’ve made from this site has been ah-ma-zing!

  26. Jen

    These are in the oven right now! Is the batter supposed to be very very thick? My brownie mix on its own called for more oil and some water, but I just followed your recipe. I assume the milk and peanut butter will add moisture. Either way, I am sure they will be amazing!

  27. These are SO RICH they just about blow the top of your head off!! If you like that kind of thing – these are def for you. If not, steer clear ๐Ÿ˜‰

  28. Christina @ ovenadventures

    I just discovered buckeyes like a year go. I can not believe they have hidden from me for so long. It was probably for the best though because I could live on them. These brownies are totally fab-u-lous

  29. Shelly,
    I was a bit skeptical but now that I’ve done it, I totally get the ‘swim in it’ reference. I would make one change however…there aren’t nearly enough nuts in that recipe so I doubled them and sprinkled the top too. Heaven! Thanks for sharing.

  30. Shana

    Buckeye brownies are in the oven…haven’t even tasted them yet, but based on the little bit I have found on your blog I know they will be fantastic! I am a self-confessed sugar-aholic…ummm, sweetened condensed milk…love it! You and I could be long lost sisters! Keep writing!

  31. Amy

    These were absolutely decadent. What a wonderful recipe. The first of many recipes I will be making from your excellent website. Thank you for sharing.

  32. Tieneke

    These are great. I made them with your “my kids favorite brownies’ and they came out great. I love the peanutbutter caramel!

  33. I just loved it, Iโ€™m not only going to give it 5 stars. But, Iโ€™m going to share it with all my websiteโ€™s followers on the social media. Thank you for giving me something useful to share it today!

  34. Chris

    I made these today and theyโ€™re delicious. Easy to make and I got lots of compliments. Next time Iโ€™ll take a little bit more care to really make sure I reserve enough brownie batter after the first pour to cover the top and not stress if I canโ€™t perfectly spread the base layer. I ran a little short for the final layer and too much of the peanut butter mixture showed through with a baked, crepey texture. Of course I was probably the only person who cared at all but you know how self-critical us bakers are. Still a hit and Iโ€™m keeping the recipe!
