Ingredients You’ll Need

6 oz semisweet chocolate (1 cup): This rich chocolate is the key to a fudgy brownie texture. Using high-quality chocolate makes a significant difference.
½ cup salted butter: Adds moisture and a touch of savory balance to the sweetness. If you’re out of salted butter, unsalted works too; just add a pinch of salt.
2 large eggs: Eggs create structure and bind everything together. Make sure they’re at room temperature for even mixing.
¾ cup granulated sugar: Sweetens the batter perfectly and helps with the brownie’s texture.
2 teaspoons pure vanilla extract: Vanilla enhances the other flavors and adds depth.
¾ cup all-purpose flour: This helps create that classic brownie density; alternative flours can be used, but the texture may vary.
1 tablespoon unsweetened cocoa powder: Intensifies the chocolate flavor without adding sweetness.
¼ teaspoon fine sea salt: Enhances the sweetness and chocolate flavor, balancing it all out.
¾ cup creamy peanut butter: The star of the show! Use a good-quality peanut butter for a smooth finish. Natural peanut butter can also work, but ensure it’s well-stirred for consistency.
¼ cup salted butter (softened): This additional butter softens the peanut butter layer, making it easy to spread.
½ teaspoon pure vanilla extract: Flavor boost for the peanut butter layer.
¼ teaspoon fine sea salt: Again, this balances the flavors of the sweet peanut butter.
1 ½ cups powdered sugar: Adds sweetness to the peanut butter layer while helping it hold its shape.
1-2 tablespoons whole milk (room temperature): Used to achieve the desired consistency of the peanut butter mixture. Adjust to your preference.
½ cup heavy cream: This is used to create a rich ganache topping.
1 cup semisweet chocolate (6 ounces): This is for the ganache; use high-quality chocolate for best results.

How to Make Buckeye Brownies

Preheat the oven: Start by preheating your oven to 350°F (177°C). Line a 9×9” baking dish with parchment paper and lightly grease it to prevent sticking.
Mix Dry Ingredients: In a small bowl, mix together ¾ cup all-purpose flour, 1 tablespoon unsweetened cocoa powder, and ¼ teaspoon fine sea salt. Set aside—this helps to ensure even distribution of dry ingredients.
Melt Chocolate and Butter: In a microwave-safe bowl or on the stovetop over low heat, melt 6 oz semisweet chocolate and ½ cup salted butter together. Stir until it’s smooth and glossy; let it cool slightly.
Beat Eggs and Sugar: In the bowl of a standing mixer, beat 2 large eggs for about 1 minute. Add ¾ cup granulated sugar and beat for an additional minute until combined.
Add Chocolate Mixture: Pour in the melted chocolate and butter mixture along with 2 teaspoons pure vanilla extract. Mix on low speed until thoroughly incorporated.
Combine with Dry Ingredients: Gradually add the dry ingredients to the wet mixture. Mix on low speed until just combined, ensuring there are no lumps, but don’t over-mix; the batter should be thick.
Spread the Batter: Pour the brownie batter into your prepared baking pan and evenly spread it out with a spatula.
Bake: Place the pan in the preheated oven and bake for 25 to 28 minutes, or until the top is set and only slightly jiggles in the center. A toothpick inserted should come out mostly clean.
Cool: Allow the brownies to cool completely in the pan on a wire rack. If you’re in a hurry, transfer them to the fridge to speed up the cooling process!
Prepare the Peanut Butter Layer: In a standing mixer, beat ¼ cup softened salted butter until smooth. Then add ¾ cup creamy peanut butter, ½ teaspoon pure vanilla extract, and ¼ teaspoon fine sea salt. Mix until it’s nicely combined.
Add Powdered Sugar: Gradually add the powdered sugar (1 ½ cups, 1 cup at a time) and mix until fully incorporated. Adjust the consistency by adding 1-2 tablespoons room temperature whole milk until you reach your desired thickness.
Spread Peanut Butter Over Brownies: Once the brownies are cool, spread the peanut butter layer evenly over the top. If you want the ganache to set better, chill the brownies for a bit more in the refrigerator.
Make the Ganache: Heat ½ cup heavy cream in a saucepan over medium heat until it begins to bubble around the edges. Turn off the heat and whisk in 1 cup semisweet chocolate until it’s smooth and shiny.
Cool Ganache: Let the ganache cool slightly, whisking occasionally until slightly thickened, then carefully spread it over the peanut butter layer.
Chill Again: Let the brownies chill in the fridge or sit at room temperature until the ganache is set—about 30 minutes to an hour is usually ideal.
Cut and Serve: Once set, cut the brownies into 16 squares and enjoy!

Storing & Reheating

To store your buckeye brownies, keep them in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week or freeze them in a suitable container for up to 3 months. If you choose to freeze, individually wrap each brownie in plastic wrap to maintain freshness. When ready to enjoy again, simply let them thaw at room temperature, or warm them briefly in the microwave for about 10-15 seconds for a cozy treat. Just remember that the texture may change slightly after freezing; a quick microwave refresh can help restore that decadent fudginess!

Chef’s Helpful Tips

Taking the time to let the brownies cool completely before adding layers makes for a prettier final product—who wants a messy cut?
For a richer flavor, try using dark chocolate instead of semisweet for the brownie base.
Room temperature ingredients mix more evenly; let your eggs and butter sit out for about 30 minutes before starting.
If you’re looking for a fluffier peanut butter layer, beat the mixture longer to incorporate more air.
For added flavor, consider a pinch of cinnamon in the brownie batter or the peanut butter layer.
These brownies can be made ahead of time—perfect for holiday gatherings! Just store as described above to keep them fresh.

Black-eyed brownies are truly a staple in every dessert lover’s collection. Bursting with flavor and boasting a delightful texture, there’s no doubt you’ll enjoy making and sharing this recipe!

Recipe FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely! Using crunchy peanut butter will give your buckeye brownies a delightful texture with a bit of crunch. Just keep in mind that it might affect the smoothness of the peanut butter layer.

How do I know when my brownies are done?

The best way to check for doneness is to look for a set top with just a tiny jiggle in the center. A toothpick inserted should come out with a few moist crumbs—this ensures that the brownies are fudgy rather than dry.

Can I make these brownies in advance?

Definitely! Buckeye brownies keep well and can be made 1-2 days ahead of when you plan to serve them. Just store them in an airtight container either at room temperature or in the refrigerator.

What’s the best way to cut brownie squares?

For silky smooth cuts, run your knife under hot water and wipe it dry between cuts. This will give you clean edges and keep those layers looking sharp!
