Ingredients You’ll Need

6 oz semisweet chocolate (1 cup): Adds deep chocolate flavor to the brownie base. You can substitute with dark chocolate for a richer taste.
½ cup salted butter: Brings moisture and richness. Unsalted butter works too; just add a pinch of salt.
2 large eggs: Essential for binding ingredients and creating a soft, chewy texture.
¾ cup granulated sugar: Sweetens the brownies while balancing their richness; brown sugar can be used for added moisture and flavor.
2 teaspoons pure vanilla extract: Enhances the overall flavor; imitation vanilla can work in a pinch, but pure is preferred.
¾ cup all-purpose flour: Provides structure. For gluten-free versions, consider using a gluten-free flour blend.
1 tablespoon unsweetened cocoa powder: Intensifies the chocolate flavor without adding sweetness.
¼ teaspoon fine sea salt: Enhances the sweet and savory balance in the brownies; don’t skip it!
¾ cup creamy peanut butter: A luscious layer on top that gives the dessert its signature flavor. Crunchy peanut butter can be a fantastic alternative for extra texture.
¼ cup salted butter (softened): Needed for the peanut butter layer, adds a creamy texture.
½ teaspoon pure vanilla extract: Offers an extra boost of flavor to the peanut butter mixture.
¼ teaspoon fine sea salt: Balances the sweetness of the peanut butter.
1 ½ cups powdered sugar: Sweetens and thickens the peanut butter layer. For a healthier option, consider using a sugar substitute.
1-2 tablespoons whole milk (room temperature): Helps achieve the perfect creamy consistency for the peanut butter layer; substitute with almond milk if necessary.
½ cup heavy cream: Essential for a rich and silky ganache.
1 cup semisweet chocolate (6 ounces): The star ingredient for the ganache topping; use dark chocolate for a deeper flavor.

How to Make Buckeye Brownies

Preheat the Oven: Start by preheating your oven to 350 degrees Fahrenheit (177 degrees Celsius). Line a 9×9” baking dish with parchment paper, making sure to lightly grease it for easy removal later.
Mix Dry Ingredients: In a small bowl, combine ¾ cup all-purpose flour, 1 tablespoon cocoa powder, and ¼ teaspoon fine sea salt. Set this aside so the flavors can mingle.
Melt the Chocolate: In a microwave-safe bowl or on the stovetop, melt 6 oz semisweet chocolate with ½ cup salted butter. Stir until it’s smooth and glossy, then let it cool slightly.
Beat the Eggs: Using a standing mixer, beat 2 large eggs for 1 minute until frothy.
Combine Wet Ingredients: Gradually add ¾ cup granulated sugar and beat for another minute. Then, mix in the cooled chocolate and butter mixture along with 2 teaspoons vanilla extract on low speed until everything is combined.
Incorporate Dry Ingredients: Pour the flour mixture into the wet ingredients and mix on low speed just until there are no lumps. The batter will be thick and rich.
Spread the Batter: Evenly spread the brownie batter in the prepared baking dish.
Bake: Place in the preheated oven and bake until the top is set, about 25 to 28 minutes. A slight jiggle in the center is okay but aim for edges that are just beginning to pull away from the pan.
Cool the Brownies: Allow your brownies to cool completely in the pan on a wire rack. If you’re in a hurry, pop them in the refrigerator or freezer for quicker cooling.
Make the Peanut Butter Layer: In a clean mixer bowl, beat ¼ cup softened salted butter until smooth. Add in ¾ cup creamy peanut butter, mixing until combined. Incorporate ½ teaspoon vanilla extract and sea salt until creamy. Gradually add in 1 ½ cups powdered sugar, mixing until fully combined. If needed, add 1 to 2 tablespoons of whole milk until you reach a spreadable consistency.
Spread the Peanut Butter Mixture: Once the brownies are completely cool, spread the peanut butter mixture evenly over them. If you like, chilling them again will help the ganache set faster later.
Prepare the Ganache: Heat ½ cup heavy cream over medium heat until bubbles form around the edges. Turn off the heat and whisk in 1 cup semisweet chocolate until smooth and glossy. Let it cool slightly while whisking until it thickens.
Top the Brownies: Once the ganache has cooled a bit, spread it evenly over the peanut butter layer.
Let Set: Chill the brownies in the refrigerator or leave them at room temperature until the ganache is fully set.
Cut and Serve: Once set, cut into 16 squares and enjoy!

Storing & Reheating

Store your Buckeye brownies at room temperature for up to two days, keeping them in an airtight container to maintain their freshness. For longer storage, they’re best kept in the refrigerator, where they’ll last for up to a week. If you want to freeze them, wrap the brownies tightly in plastic wrap followed by aluminum foil. They’ll stay delicious for up to 3 months. To enjoy them again, simply let them thaw at room temperature or warm them in the microwave for about 10-15 seconds to refresh their fudgy decadence.

Chef’s Helpful Tips

Avoid Overmixing: When combining the dry and wet ingredients, mix just until incorporated. Overmixing can cause the brownies to become tough.
Check for Doneness: Use a toothpick inserted in the center—if it comes out with moist crumbs, the brownies are done. If it’s covered in batter, give them a few more minutes.
Use Room Temperature Ingredients: For the best peanut butter layer, ensure your butter and milk are at room temperature to achieve that perfect creamy consistency.
Customize Your Toppings: Feel free to sprinkle some chopped nuts or crushed cookies on the ganache for added texture and flavor.

The balance of rich chocolate brownies with creamy peanut butter and silky ganache will have you returning to this recipe time and time again. Don’t hesitate to experiment with the flavors—whether it’s adding a sprinkle of sea salt on top or infusing the ganache with espresso, there’s always room for a personal touch!

Recipe FAQs

Can I make these brownies gluten-free?

Absolutely! Simply substitute the all-purpose flour with a gluten-free flour blend. The texture might vary slightly, but they will still be delicious.

How do I know when the brownies are done baking?

Check for doneness by inserting a toothpick into the center. If it comes out with a few moist crumbs, they’re ready to come out of the oven. If it’s wet with batter, bake them a bit longer.

Can I use a different type of chocolate?

Certainly! You can use dark chocolate for a richer flavor or even milk chocolate for a sweeter, creamier taste. Just keep the total weight the same.

How long do I need to let them cool before serving?

Let the brownies cool completely in the pan before you cut them. This will ensure that they hold their shape and the layers set properly. If you’re in a hurry, placing them in the refrigerator can speed up this process!
