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.

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

  1. 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.

  2. 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!

  3. 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?

  4. 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.

  5. 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.

  6. 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!

  7. 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!

  8. Great seeing you this weekend. 🙂 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. 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!!!

  10. Victoria

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

  11. 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 🙂

  12. 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. 🙂

  13. Emily F

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

  14. 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.
