Buckeye Cake

Your favorite homemade candy is now available as an entire buckeye cake. This peanut butter cake with chocolate frosting is decorated to look just like a buckeye!

I was compensated for this post by the Ohio Poultry Association and the ADA Mideast, but the recipe and subject matter were of my choosing. All thoughts and opinions are my own.

Whenever I’ve seen recipes for buckeye-themed cakes, they are always predominantly chocolate. But if you are familiar with the buckeye candy you are well aware that it is a nugget of peanut butter dipped in chocolate, with peanut butter as the majority.

So I took it upon myself to correct this dilemma in the buckeye-themed baking world and made not only a peanut butter cake with chocolate frosting, but I decorated the entire thing to resemble a giant buckeye nut.

Buckeye Cake Ingredients.

Buckeye cake main ingredients

  • All-purpose flour
  • Unsalted butter
  • Shortening
  • Peanut butter
  • Chocolate
  • Sugar
  • Eggs
  • Milk

As always, every baking recipe that I share uses large eggs. If you use a different size it will impact the consistency of the cake. But no worries, if you don’t have large eggs you can use this conversion chart to learn how to substitute.

Once you’ve settled the egg size, make sure to set them out for 30 minutes to let them come to room temperature. This will make it easier to mix them into the batter.

I actually have made peanut butter cake before, but only in either sheet cake form or cupcakes 1/2/3 (and yes I have done the chocolate cake with peanut butter frosting version as well). But this is my first peanut butter layer cake.

Once you bake the two layers and let them cool, you only need to slice the top of one layer to level it because the top we want to be round – better to look like a round buckeye!

After coating it with chocolate frosting I added a dollop of peanut butter frosting to the top to give it the “eye” of the buckeye. Who needs the eye of a tiger when you can have the eye of a buckeye? That should be a song.

This recipe is also featured on the Ohio Poultry Association website OhioEggs.com, where you can also learn more about Ohio Farming. Did you know that Ohio is ranked number 3 in the nation for eggs farming, producing over 10 billion eggs a year. Ohio is also 10th in the nation for milk production, with over 250,000 dairy cows in Ohio producing 628 million gallons of milk a year.

Do you know where your eggs and milk come from?
