Ingredients You’ll Need

Every layer of Buckeye Brownies depends on a handful of pantry staples — think peanut butter, chocolate, and a perfectly fudgy brownie base. Each ingredient is there to bring bold flavor, luscious texture, or a finishing touch of sweet magic.

Best Brownie Recipe: Your favorite rich and fudgy brownie base is the foundation for these bars, so make sure to pick one that delivers big chocolate flavor and a moist crumb.
Creamy Peanut Butter: For that classic buckeye taste and silky texture, creamy peanut butter blends seamlessly into the luscious middle layer.
Unsalted Butter: Room temperature butter adds creaminess to the peanut butter layer, so it spreads smoothly for a perfect bite.
Powdered Sugar: This sweetens and thickens the peanut butter layer, making it fluffy and easy to slice cleanly.
Pinch of Salt: Just a bit of salt sharpens all the flavors — don’t skip it!
Vanilla Extract: A splash of vanilla gives the peanut butter layer depth and bakery-level aroma.
Semisweet Chocolate Chips: These form the luxurious top layer, balancing sweetness with a rich, chocolatey finish.
Heavy Cream: Just a few tablespoons make your ganache silky, shiny, and easy to pour over the bars.

How to Make Buckeye Brownies

Step 1: Bake and Cool the Brownie Layer

Start by preparing your favorite brownie recipe and lining your pan thoroughly with parchment paper, making sure it extends up all sides for easy removal. Bake them according to the recipe’s instructions, then let the brownies cool completely in the pan. This step is key — if you rush it, the gooey peanut butter topping will melt into a mess!

Step 2: Whip Up the Peanut Butter Layer

In a mixing bowl, beat room temperature unsalted butter and creamy peanut butter together with a hand mixer or sturdy spoon until smooth and fully blended — about a minute is all it takes. Gradually add in the powdered sugar, a pinch of salt, and vanilla extract, stirring until the mixture becomes thick, fluffy, and there are no lumps left. Spread the peanut butter layer evenly over the cooled brownies, using a spatula to make sure it reaches every edge. Set the pan aside while you prep the topping.

Step 3: Make the Chocolate Ganache

In a microwave-safe bowl, combine semisweet chocolate chips and heavy cream. Microwave in 30-second intervals, stirring well between each round, until the mixture is completely smooth and glossy. This quick homemade ganache pours like a dream and hardens into the perfect top coat. Immediately pour the ganache over the peanut butter layer, gently tilting and smoothing so it covers every inch.

Step 4: Chill and Set

Transfer the entire pan of assembled Buckeye Brownies to the fridge and let them chill for at least 1 hour, or until the chocolate topping is fully set. Once chilled, lift the brownies out of the pan using the parchment, then slice into generous bars. Each square will reveal distinct, mouthwatering layers!

How to Serve Buckeye Brownies

Garnishes

A little flourish goes a long way with Buckeye Brownies! Sprinkle a handful of mini chocolate chips, chopped roasted peanuts, or even a pinch of flaky sea salt on top of the ganache before it sets for extra crunch and visual flair. You can also drizzle additional melted peanut butter in zigzags for that bakery-style finish.

Side Dishes

These brownies are incredibly rich, so they love a partner that offers contrast. Serve Buckeye Brownies with a scoop of vanilla or coffee ice cream, a tall glass of milk, or a cup of strong hot coffee to cut the sweetness and add balance to the plate.

Creative Ways to Present

For parties, cut the brownies into bite-size squares and serve them nestled in mini cupcake liners on a platter. Or, get fancy and layer small brownie cubes into dessert jars with extra whipped cream and chopped peanuts for a parfait-style treat. Gift box them up for friends and family — these bars travel beautifully and are always adored!

Make Ahead and Storage

Storing Leftovers

To keep your Buckeye Brownies fresh, store them in an airtight container at room temperature or in the fridge. They’ll hold their texture and flavor for up to a week — if they last that long! Placing parchment paper between layers helps keep them from sticking together.

Freezing

Absolutely, Buckeye Brownies freeze like a dream. Simply wrap individual bars tightly in plastic wrap and then in foil, or stack them with parchment between layers in a freezer-safe container. They’ll stay delicious for up to 2 months; just thaw at room temperature before serving.

Reheating

These brownies are delightful chilled, but if you want that gooey, just-baked vibe, pop a square in the microwave for 10-15 seconds. The ganache softens and the scent of chocolate and peanut butter fills the kitchen all over again.

FAQs

Can I use a boxed brownie mix for Buckeye Brownies?

Definitely! While homemade brownies add an extra layer of love, a high-quality boxed brownie mix makes things super convenient and still delivers fudgy results. Just make sure to use one you know and love as the base.

What kind of peanut butter works best?

Stick to classic creamy peanut butter for the iconic texture that Buckeye Brownies are famous for. While natural peanut butter can work, it may be a bit runnier and separate, so stir it well if you go that route.

Can I make these gluten-free?

Absolutely. Prepare your favorite gluten-free brownie base and follow the same steps for the peanut butter and ganache layers. Every other ingredient is naturally gluten-free, so you won’t need further swaps.

How long will Buckeye Brownies stay fresh?

Stored properly in an airtight container, they’ll keep beautifully for up to one week in the fridge. They can also be frozen for longer storage if you want to stock up.

Why is it called a “Buckeye” brownie?

The name comes from the resemblance to classic Buckeye candies, which are peanut butter balls dipped in chocolate and look like the nut from Ohio’s buckeye tree. Buckeye Brownies take those flavors and layer them over a brownie base for a handheld treat!
