Buckeye Brownies

It’s that time of year, the time for all the delicious sweets and treats to be made and shared with friends and families. These glorious buckeye brownies are the perfect mix of chocolate and peanut butter that will leave your tastebuds asking for more.

Some of you might be wondering what exactly is a buckeye. Well the name “buckeye” comes from Ohio. These wonderful desserts are meant to resemble the nut that comes from the Ohio buckeye tree. 


With these when you cut into the brownies you will be able to see all of the peanut butter and chocolate layers just like if you were to cut into a buckeye nut.

If you are looking to add an extra special touch to these peanut butter chocolate brownies, maybe try your hand at making your own peanut butter with THIS recipe for the Food Network. Just be sure to make it creamy! 

Can you use chunky peanut butter for this recipe? You can, but it will not give the same texture we are looking to achieve for the chocolate and peanut butter layered brownies.

Let’s start with the brownie layer. Begin by preheating the oven to 325 degrees. Then, get out your favorite 9 x 13 pan (THIS is my favorite one) and grease it up. 

Then, melt the butter and after it is melted, add in the cocoa and stir it together well. Once those have been combined, add in the sugar and eggs to the butter and cocoa mixture mixing and combine it all together.

Lastly, add in the vanilla, flour, and salt to the creamed cocoa and sugar mix. Beat everything together until it is well incorporated. 

Then, simply pour everything into the 9 x 13 pan and bake it for 25 – 30 minutes, or until the brownies are cooked all the way through. 

You will then top the brownies with the peanut butter layer and then pour the chocolate ganache and spread it evenly over everything. THESE angled spatuals make spreading the chocolate ganache evenly very easy!

*Remember, if you are wanting to use a brownie box mix skip the brownie making step and replace it with the box steps for the brownies.*


To begin the peanut butter layer, place the peanut butter and softened butter into a medium sized bowl and mix it all together on medium speed until the peanut butter mixture becomes light and creamy. 


Be sure to scrape down the bowl and then add in the powdered sugar, milk, vanilla and salt. Beat it all together for another minute and then scrape the bowl down again. Then, turn the mixture back on medium speed until the peanut butter mixture becomes smooth and creamy. 

Spread this layer over top of the brownies. 


Melt together the chocolate chips and butter in a microwave safe bowl for 2 minutes and 30 second intervals. Be sure to stir the chocolate and butter together in between. You will continue this until all the chocolate is melted and smooth. 

Lastly, spread the chocolate ganache over top of the peanut butter layer and then let it cool until if hardens. 

TIP: You can place this in the fridge to speed up the cooling process a bit.
