Ingredients You’ll Need

6 oz semisweet chocolate (1 cup): The star of the brownie base, providing that rich chocolate flavor. You can substitute with dark chocolate if you prefer a more intense flavor.
½ cup salted butter: This adds moisture and a slight saltiness that balances the sweetness. Unsalted butter works too, but add a pinch of salt for flavor.
2 large eggs: Essential for binding the brownies together and providing a rich texture. Ensure they are at room temperature for better mixing.
¾ cup granulated sugar: This sweetens the brownies and contributes to their chewy texture.
2 teaspoons pure vanilla extract: Adds a warm note of flavor that enhances the chocolate and peanut butter.
¾ cup all-purpose flour: The backbone for structure. You can swap in a gluten-free flour blend to make this gluten-free.
1 tablespoon unsweetened cocoa powder: Extras that intensify the chocolate flavor without adding sweetness.
¼ teaspoon fine sea salt: Just a touch to enhance the flavor and balance the sweetness.
¾ cup creamy peanut butter: Provides the signature taste and creaminess to the peanut butter layer. Use natural peanut butter for a wholesome option.
¼ cup salted butter (softened): For the peanut butter layer; it keeps it smooth and spreadable.
½ teaspoon pure vanilla extract: A little extra flavor to enhance the peanut butter cream.
¼ teaspoon fine sea salt: Helps to elevate the peanut flavor in the layer.
1 ½ cups powdered sugar: Sweetens the peanut butter layer and gives it that luscious texture; confectioners’ sugar works best.
1-2 tablespoons whole milk (room temperature): To adjust the consistency of the peanut butter cream as needed.
½ cup heavy cream: For making that rich ganache topping; it makes the chocolate silky smooth.
1 cup semisweet chocolate (6 ounces): Perfect for the ganache, creating that dreamy finish.

How to Make Buckeye Brownies

Preheat the Oven: Begin 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 the Dry Ingredients: In a small bowl, whisk together the flour, unsweetened cocoa powder, and fine sea salt. This mix will enhance the structure of your brownies.
Melt Chocolate and Butter: In a microwave-safe bowl or over low heat on the stovetop, melt the 6 oz of semisweet chocolate and ½ cup of salted butter together. Stir until smooth and glossy; let cool slightly.
Beat the Eggs: In the bowl of a standing mixer, beat the two large eggs on medium speed for one minute until frothy.
Incorporate Sugar: Add the ¾ cup of granulated sugar to the eggs, beating for an additional minute.
Add Chocolate Mixture and Vanilla: With the mixer on low speed, add the cooled chocolate and butter mixture along with 2 teaspoons of pure vanilla extract until fully combined.
Combine with Dry Ingredients: Gently add the dry ingredients to the egg mixture and mix on low speed until just incorporated. Avoid overmixing; the batter should be thick and luscious.
Spread the Batter: Evenly pour the brownie batter into the prepared baking pan, smoothing the top with a spatula.
Bake: Place in the preheated oven and bake for 25 to 28 minutes. The brownies should look set on top and be only slightly jiggly in the center.
Cool the Brownies: Allow the brownies to cool completely in the pan on a wire rack. If you’re in a hurry, trying popping them into the refrigerator for a quicker cool down.
Prepare the Peanut Butter Layer: In a mixing bowl, beat the ¼ cup of softened salted butter until smooth. Mix in the ¾ cup of creamy peanut butter until fully combined.
Incorporate Vanilla and Salt: Beat in the ½ teaspoon of vanilla extract and ¼ teaspoon of fine sea salt, mixing until creamy.
Add Powdered Sugar: Gradually add the 1 ½ cups of powdered sugar, one cup at a time, mixing well after each addition.
Adjust Consistency: Add 1 tablespoon of whole milk, mixing until combined. Check if the mixture is spreadable. If it’s too thick, add an additional tablespoon of milk.
Spread Peanut Butter Mixture: Carefully spread the peanut butter mixture over the cooled brownies. For best results, chill them in the fridge briefly to help the layers set.
Make the Ganache: Heat the ½ cup of heavy cream over medium heat until it just begins to bubble at the edges. Turn off the heat and whisk in the 1 cup of semisweet chocolate until fully smooth.
Cool the Ganache: Allow it to cool slightly while whisking occasionally until it thickens just a touch.
Top the Brownies: Evenly spread the ganache over the peanut butter layer on the brownies.
Set the Ganache: Let the brownies chill in the refrigerator or sit at room temperature until the ganache is fully set.
Serve and Enjoy: Once set, cut into 16 squares and serve your irresistible buckeye brownies!

Storing & Reheating

To store your buckeye brownies, place them in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Alternatively, you can freeze them for up to 3 months. Just wrap each brownie individually in plastic wrap and place them in a freezer-safe container. When you’re ready to enjoy them again, simply thaw at room temperature or warm in the microwave for 10-15 seconds to refresh their gooey texture.

Chef’s Helpful Tips

Avoid Overmixing: Brownies do best when mixed just until combined; overmixing can lead to a denser texture.
Room Temperature Ingredients: Ensure your eggs and butter are at room temperature for a smoother integration into the batter.
Baking Time: Keep an eye on your brownies as they bake. If a toothpick comes out with moist crumbs, they’re perfect.
Flavor Boost: Consider folding in chocolate chips or nuts to give your brownies extra texture and flavor.
Chill for Better Layers: For cleaner cuts, chill the brownies after adding the peanut butter layer and before adding the ganache.

These buckeye brownies are not just a treat; they’re a labor of love that comes together effortlessly, creating a delightful dessert that will impress everyone. So why not try your hand at these delectable treats? Each bite will remind you of the joy of home baking.

Recipe FAQs

Can I make Buckeye Brownies ahead of time?

Absolutely! You can prepare buckeye brownies a day in advance. They taste even better after resting since the flavors develop beautifully. Just keep them covered in an airtight container in the refrigerator.

What if I don’t have semisweet chocolate?

No worries! You can easily substitute semisweet chocolate with dark chocolate or milk chocolate. Just keep in mind that dark chocolate will add a richer flavor, while milk chocolate will give a sweeter profile.

How can I adjust the sweetness?

If you prefer less sweetness in your brownies, you can reduce the amount of granulated sugar or powdered sugar in the recipe. Just be mindful that reducing sugar will also affect the texture slightly.

Can I make these brownies gluten-free?
