Irresistible Flavor: The deep chocolate flavor, combined with creamy peanut butter, creates a blissful experience in every bite.
Eye-Catching Appeal: The stunning layers make them a showstopper on any dessert table.
Flexible Serving: Perfect for parties, family gatherings, or as an afternoon treat with coffee.
Diet-Friendly Options: Easily swap ingredients to adjust for gluten-free or dairy-free versions.

Ingredients You’ll Need

6 oz semisweet chocolate: This provides the base of the decadent brownie layer, lending richness and moisture. If you’re looking for a similar flavor, dark chocolate is a great substitute.
½ cup salted butter: Butter adds tenderness and depth of flavor. Unsalted butter works too; just add a pinch of salt.
2 large eggs: Eggs bind the ingredients and help create that desirable chewy texture.
¾ cup granulated sugar: Sugar sweetens the brownies and helps with texture. You can use less sugar if desired.
2 teaspoons pure vanilla extract: Vanilla enhances the flavor profile. Using pure extract is best for a richer taste.
¾ cup all-purpose flour: This provides the structure for your brownies. For a gluten-free version, consider using a gluten-free baking mix.
1 tablespoon unsweetened cocoa powder: This intensifies the chocolate flavor. Dutch-process cocoa can be used as an alternative.
¼ teaspoon fine sea salt: Salt balances the sweetness and enriches flavors. Sea salt is preferred for its texture.
¾ cup creamy peanut butter: Essential for that classic buckeye flavor. Crunchy peanut butter can also be used if you enjoy some texture.
¼ cup salted butter (softened): Used for the peanut butter filling, it adds creaminess. Softening is key for easy mixing.
½ teaspoon pure vanilla extract: Again, this enhances the flavor, making the filling irresistible.
¼ teaspoon fine sea salt: Just a bit in the filling for balanced flavor.
1 ½ cups powdered sugar: Sweetens the peanut butter filling, giving it a delightful creaminess.
1-2 tablespoons whole milk (room temperature): Helps achieve your desired consistency in the filling; add more if needed.
½ cup heavy cream: Essential for the ganache layer that tops the brownies.
1 cup semisweet chocolate (6 ounces): This is melted into a smooth ganache. You can also opt for dark chocolate if you prefer a richer taste.

How to Make Buckeye Brownies

Preheat Your Oven: Start by setting your oven to 350°F (177°C). Line a 9×9” baking dish with parchment paper and lightly grease it to ensure easy removal later.
Mix Dry Ingredients: In a small bowl, whisk together ¾ cup all-purpose flour, 1 tablespoon unsweetened cocoa powder, and ¼ teaspoon fine sea salt. This mixture adds structure to your brownies.
Melt Chocolate and Butter: Combine 6 oz semisweet chocolate and ½ cup salted butter in a microwave-safe bowl, heating it until melted. Stir until smooth and glossy, then let it cool slightly.
Beat the Eggs: In the bowl of a standing mixer, beat 2 large eggs for 1 minute. This incorporates air into the mixture.
Incorporate Sugar: Add ¾ cup granulated sugar to the eggs and beat for an additional minute until mixed well.
Combine Mixtures: Pour in the cooled chocolate-butter mixture along with 2 teaspoons pure vanilla extract. Mix on low speed until fully blended.
Add Dry Ingredients: Gradually add your dry ingredients from step 2, mixing just until incorporated. The brownie batter should be thick, so be sure not to over-mix.
Spread the Batter: Evenly distribute the brownie batter in the prepared baking pan, smoothing the top with a spatula.
Bake: Place the pan in the preheated oven and bake for 25 to 28 minutes. The top should be set but still slightly jiggly.
Cool Completely: Once baked, allow the brownies to cool in the pan on a wire rack. For a quicker cooling time, consider putting them in the fridge.
Prepare the Peanut Butter Filling: In a mixing bowl, beat ¼ cup softened salted butter until smooth. Then mix in ¾ cup creamy peanut butter until well combined.
Combine Flavorings: Add in ½ teaspoon pure vanilla extract and ¼ teaspoon fine sea salt, mixing until smooth.
Add Powdered Sugar: Gradually mix in 1 ½ cups powdered sugar, one cup at a time, until fully incorporated.
Adjust Consistency: If needed, add 1-2 tablespoons of whole milk to achieve a creamy consistency that’s easy to spread.
Spread the Peanut Butter Filling: Gently spread the peanut butter mixture over the cooled brownies. For quicker ganache setting, chill the brownies in the fridge.
Make the Ganache: In a saucepan, warm ½ cup heavy cream over medium heat, bringing it close to a simmer without boiling.
Whisk in Chocolate: Once the cream is bubbling around the edges, remove it from heat and whisk in 1 cup semisweet chocolate until smooth.
Cool the Ganache: Let the ganache cool slightly, whisking occasionally until it thickens a bit.
Top the Brownies: Pour the ganache over the peanut butter layer, spreading it evenly.
Set the Ganache: Allow the brownies to set in the fridge or let them sit at room temperature until the ganache firms up.
Serve: Cut into 16 squares and share the joy!

Storing & Reheating

To keep your buckeye brownies at their best, store them in an airtight container at room temperature for up to three days. If you need longer storage, pop them in the fridge for about a week or freezer-friendly for up to three months. To reheat, simply place individual squares in the microwave for about 10-15 seconds. Just note that the texture might change slightly after freezing, but a quick warm-up will refresh their rich flavors.

Chef’s Helpful Tips

Ensure your eggs are at room temperature for a smoother batter.
Use a toothpick to check brownie doneness; it should come out with a few moist crumbs for that fudgy texture.
Make sure your chocolate is adequately cooled before adding to avoid cooking the eggs.
If your brownies are too gooey after baking, they may need a bit more time in the oven.
These brownies can be made in advance; just wait to add the ganache until the day of serving for the best appearance.

Buckeye brownies are truly a beloved dessert that embodies both whimsy and indulgence. Their layers of chocolate, peanut butter, and creamy ganache create each heavenly mouthful. Whether you’re indulging solo or sharing with friends, these brownies ooze comfort and joy. Don’t hesitate—you’ll want to whip up this delightful treat again and again!
