Finding The Flavor In This Recipe For Buckeye Cake
The chocolate cake, homemade peanut butter frosting, and chocolate ganache each have an ingredient that makes them stand out! Together, all three team up to make a dessert that’s completely out of this world delicious!
The chocolate cake is made from scratch using mostly pantry staple ingredients! The one exception, and stand-out ingredient, is the espresso powder.
Espresso powder intensifies the chocolate flavor in the cake. Making for one incredibly delicious chocolate cake!
Making it the perfect base for that fluffy peanut butter frosting! I find the frosting tastes best when it’s made with Jif creamy peanut butter.
After that, is the chocolate ganache! Where the star ingredient is the finely chopped bittersweet chocolate.
My favorite brand to use is Ghirardelli Premium Baking Chocolate that’s 60% Cacao. It truly yields the tastiest results!
Helpful Recipe Tips!
- Preparing The Pan – Grease the cake pan with butter and line it with parchment paper. This will ensure removing the cake is as easy as possible.
- Frosting Consistency – The peanut butter frosting should be perfectly light and fluffy. If needed, you can add additional cream or powdered sugar to help you reach the desired consistency.
- Drops Of Frosting – I recommend using a large or medium size cookie scoop to drop mounds of frosting all over the baked and cooled cake. This trick disperses the frosting in even amounts that look nice!
- Chocolate Ganache – The ganache is very rich and has a slightly bitter dark chocolate flavor. If you prefer it to be sweeter you can whisk in 1/4 cup of powdered sugar.
- Slicing and Serving – Allow the chocolate ganache to cool completely before slicing and serving the cake. When serving, be sure each slice has one mound of frosting!

How Do I Store This Chocolate Peanut Butter Buckeye Cake?
This Chocolate Peanut Butter Cake is best stored in an airtight container in the refrigerator. Leftover cake can then be enjoyed for up to one week.
Can I Just Use A Boxed Chocolate Cake Mix?
I personally always doctor-up boxed cake mixes when I use them like in my Chocolate Cupcakes, but I think this recipe really deserves a cake batter made from scratch. Whereas this Buckeye Cake Recipe from scratch has lots of rich, decadent flavor, something you can’t get from a boxed mix!
However, if you’d like, a boxed chocolate cake mix can be used instead.
What Do I Do With The Leftover Chocolate Ganache?
If you have leftover ganache store it in the fridge in an airtight container for up to 2 weeks. Then you can just use it for a dip with fresh fruit, pretzels, or marshmallows!
Could I Just Spread The Frosting Out Instead Of Dropping Scoops Of It Onto The Cake?
Yes, you could do that. Just keep in mind doing so will cause you to lose the classic look of a buckeye ball. But you could make and top with Buckeye Candy instead.
