They are the perfect homemade sweet treats to take care of your chocolate cravings with a bout of peanut butter goodness mixed in! Believe me, these homemade layered brownies will get you extra brownie points with everyone! (pun intended!)

The Best Buckeye Brownie Recipe

While a few can resist a homemade brownie, I never saw anyone who has the power to turn down these Buckeye Brownies. Because who could possibly resist such dessert? I mean, just look at those dreamy layers! They are like Reese’s peanut butter cups but bigger and better! You get the creamy peanut butter filling and rich chocolate layer but in a scrumptious brownie form.

In true “me” fashion, I decided to forgo making the brownie base from scratch and used a box of brownie mix. Saved me tons of time and effort while still getting the desired outcome. Just like on my Christmas Brownies and Pecan Pie Brownies. Watching just how fast this batch of brownies became a crowd favorite, I think no one minded! 

Why are they called Buckeye Brownies?

These brownies are an adaption of Buckeye candies. They are popular treats in the state of Ohio and nearby places because of their resemblance to the nuts of an Ohio buckeye tree. The original recipe is made with a ball of peanut butter fudge partly dipped in melted chocolate.

STEP 3: Make the Ganache.

Measure the chocolate into a medium-sized glass bowl with a lid or plate that can be used to cover it. Set aside.

Melt the butter in a small saucepan over medium heat, then add the cream. Whisk it together constantly while increasing heat to medium-high. Cook until it just starts forming bubbles.

Pour the cream mixture into the bowl of chocolate and cover it with the lid. Let it sit for 5 minutes.

Tips When Making Buckeye Brownies

  • When placing the parchment paper on the baking dish or pan, make sure to leave some overhang for easier extraction of the fudgy brownies.
  • Do not overmix your brownie batter, and make sure to check on the instructions indicated on the package and follow accordingly.
  • Make sure that the brownies are completely cooled before spreading the peanut butter layer on top of it. Or else, they will melt together, creating a mess instead of a neat layer.
  • I observed that the brownies cut better once they are well chilled. Also, clean your knife every time you slice to make perfectly neat squares.
  • These are ideally served chilled, but if you prefer, you can also serve them at room temperature.

Storing Notes

You can store the brownie bars in the refrigerator for 5 days. Just make sure to put them in an airtight container. If you want to freeze them, wrap them individually in plastic wrap or foil and place them in a freezer Ziploc bag. They will keep in the freezer for up to three months.

Frequently Asked Questions for Buckeye Brownies

Can I use milk chocolate chips instead of semi-sweet?

I find that milk chocolate chips don’t provide as nice of a contrast to the sweetness of the brownies and peanut butter. But you are welcome to experiment.

I don’t have any heavy cream- what can I do?

You could make the top layer using just the chocolate chips along with ½ cup of salted butter. Also, add 2 Tablespoons of milk if you have it, although you could make it without. Just keep in mind that the texture will be firmer but still delicious.

Can I make this with sugar-free or natural peanut butter?

I find that regular peanut butter works better in this recipe.

I can’t find a boxed mix that will make a 9X13 pan of brownies, only 8X8 or 9X9 – what should I do?

You could just use 2 boxes of those smaller mixes and do them together in the 9X13 pan. Or, if you would prefer, make just one 8X8 or 9X9 pan, and then you will half the recipe for the peanut butter layer and the ganache layer.

Do I need to allow these to chill – I want to eat them right away!

You certainly can eat them right away; they will just be a little messy. Chilling them will allow you to cut them more neatly.

Can I use my own recipe to make homemade brownies?

Of course, if you have the time to make it from scratch, you can use any recipe you’d like.

I don’t have salted butter; can I use unsalted butter instead?

Yes, just add an extra ¼ teaspoon of salt to your mixture

Brownie base

  • 1 box Brownie mix for 9X13 pan or 2 boxes of 8X8. plus ingredients as directed on box (usually eggs, water and oil)

Peanut butter layer:

  • 2 ½ cups icing sugar
  • 1 ½ cup peanut butter
  • ½ cup salted butter melted
  • ½ teaspoon vanilla
  • pinch of salt

Ganache layer:

  • 2 cups semisweet chocolate chips or chopped chocolate
  • 1 cup heavy cream
  • 2 Tablespoons salted butter

Instructions

  • Prepare a 9X13 baking pan by lining it with parchment paper.
  • Preheat the oven to the temperature recommended on the box mix.
  • Prepare the brownie mix according to the directions on the package and bake for the recommended time and allow them to cool.
  • While the brownies are cooling, prepare the peanut butter layer and then the ganache layer.
  • With a hand mixer, beat until smooth the icing sugar, peanut butter, butter, vanilla and salt. This will end up as a thick, playdough consistency. Set this aside.
  • Next we will make the ganache. Measure the chocolate into a medium sized glass bowl (you will need a lid or plate that will cover this) and set this aside.
  • Melt the butter over medium heat in a small saucepan. When the butter is melted, stir in the cream.
  • Whisk this together constantly while increasing the heat to medium high. Cook this until it just starts forming bubbles.
  • Immediately, pour the cream mixture over the bowl of chocolate and cover it with the lid. Let this sit for 5 minutes.
  • Then stir to combine the chocolate and cream mixture. It may take a minute or two of stirring, but you should create a smooth ganache.
  • As the ganache cools, it will thicken slightly. That is fine. Just stir it up again when you are ready to spread it.
  • Once the brownies have cooled a bit, spread on the peanut butter mixture by scooping out spoonfuls of the mixture onto the brownie layer, then using a spatula to smooth it out and cover the brownie layer completely.
  • Pour the ganache on top and smooth out.
  • Place the buckeye brownies into the fridge to allow them to cool and set for easier cutting. They will need at least ½ an hour.
