What are buckeye brownies?

The recipe has a decadent brownie layer, creamy peanut butter layer and everything is topped with chocolate ganache. It is such a decadent treat and simple to make.

There are three delicious layers:

  • Brownie. This fudgy chocolate layer is rich and decadent. It is the base of the recipe.
  • Peanut Butter filling. Everything you love about peanut butter balls is in this layer. The creamy peanut butter and powdered sugar make for a luscious combination.
  • Chocolate topping. The delicious chocolate topping takes this recipe to the next level. Not only does it look pretty but it tastes amazing. It is made from heavy whipping cream and chocolate for a rich topping.

Ingredients: 

Ingredients for buckeye brownies- oil, eggs, peanut butter, brownie mix, chocolate chips, butter, powdered sugar.

For the Brownies

  • Box Brownie Mix (for 9X13 pan size brownies)

The Peanut butter Layer

  • Creamy Peanut Butter. I like Jif or Skippy.
  • Butter, melted 
  • Powdered Sugar 

For the Chocolate Ganache

  • Milk Chocolate Chips
  • Heavy Cream 

You can get the complete ingredient list at the bottom in the recipe card.

Substitutions and Additions

  • Chocolate. You can use dark chocolate chips or semi-sweet chocolate chips in this recipe if you prefer. Another option is milk chocolate chips but it will be sweeter and slightly creamier.
  • Additional toppings. While the classic recipe most closely resembles buckeye candies, feel free to add your spin on it. Some ideas include: chopped nuts, sprinkles and crushed candy.
  • Homemade brownie mix. You can make homemade Brownies instead of using a box mix if you prefer. Either option is fine.

Frequently Asked Questions

Do these need to chill?

Yes, the chocolate topping needs time to harden. It normally takes at least 2 hours for the layers to set.

Don’t try to cut the brownies before they have set or you will not have the gorgeous clean layers.

How to store?

Refrigerate the leftover brownies in a covered dish for up to 5 to 7 days.  It is important to keep them chilled so they last longer.

How to freeze?

Once you have cut the brownies into individual slices, flash freeze them for 1 to 2 hours on a baking sheet.

Then wrap them in plastic wrap and again in foil. Next, place the brownies inside a freezer container or bag.

They can be frozen up to 3 months. Since they were flash frozen initially, they will not stick and be very easy to freeze.
Plus, individually wrapping them allows for you to easily grab a brownie.

Tips and tricks:

  • Make sure that you use a brownie mix that includes instructions on how to make the brownies in a 9X13 pan.  This is the size needed for this recipe.
  • You might want to line your baking dish with parchment paper. This will allow for you to easily lift the brownies out for cutting.
  • Cut the brownies while they are still chilled. Wipe any excess off the knife between cuts. This will ensure each one looks nice.
  • Creamy peanut butter works best in this recipe. I do not recommend substituting natural peanut butter.
  • The chocolate topping needs to made using heavy whipping cream. Milk should not be substituted as it will not have the same creamy results.
