Let me tell you why I love this recipe so much. First off, we’re talking about chocolate and peanut butter and that combination is always a fave! And though there are many “Buckeye Brownies” on the internet, I love this one because you get a nice thick brownie (this is why I use a square pan rather than a 9×13), plenty of peanut butter flavor and a topping that reminds me of the classic peanut butter buckeye treats!

What are Peanut Butter Buckeyes?

Similar to a peanut butter ball, but buckeye candies aren’t quite fully dipped in chocolate (only about 7/8 of the way). They’re meant to look like the nut that falls from the Ohio buckeye tree and are super popular around the holiday season.

Ingredients needed for Peanut Butter Brownies (Buckeye Brownies).

Ingredients (Full list in recipe card)

  • Boxed Brownie Mix + Ingredients listed on the box – You can use milk chocolate, dark chocolate, fudgy brownies, etc. You just want to make sure there’s instructions for making them in a square (8×8 or 9×9 inch pan).
  • Peanut Butter – I recommend creamy peanut butter for this recipe. Do not use “natural” peanut butter that needs stirred before use as it will affect the texture.
  • Powdered Sugar
  • Vanilla Extract
  • Butter – I use salted butter in these.
  • Chocolate Chips – I like using semi-sweet chocolate chips for the topping, but milk or dark chocolate chips will work great, too!

How to Make Buckeye Brownies

Make the Brownie Layer

Simply follow the instructions on a box of brownie mix, mixing it and pouring the brownie batter into a square pan lined with parchment paper or greased with cooking spray. Spread to an even layer and bake as instructed on the box.

Make the Peanut Butter Layer

I find this layer to be easiest to mix with a hand mixer or stand mixer. You’ll combine the peanut butter, melted butter and vanilla then stir in the powdered sugar. It’ll thicken a bit as it cools, but once you drop spoonful’s onto the warm brownies, it’ll be easier to spread to the edges of the brownies.

Make the Chocolate Layer

Add chocolate chips and a little vegetable oil to a microwave-safe bowl. Give it a stir then microwave in 30-second intervals, stirring after each until smooth. Spread the melted chocolate over the top of the brownies.

Recipe Notes

Can I use homemade brownies instead of a box?

Absolutely! If you have a recipe for a square pan, that’s perfect. If it’s a homemade brownie recipe for a 9×13-inch pan and it’s a good thick brownie, you can go that route, too. Simply double the peanut butter and chocolate layers to account for the larger size pan.

How should I store buckeye brownies?

You can cover the pan of cooled brownies with plastic wrap or place them in an airtight container at room temperature. You can also freeze them for up to three months in a well-sealed container or freezer bag.
