Buckeye Brownies Ingredients

For the Brownie Base
Brownie Mix – Use a store-bought blend for an easier, fuss-free option, or whip up your favorite homemade recipe.

For the Peanut Butter Layer
Creamy Peanut Butter (1/2 cup) – This ingredient adds richness and creaminess; feel free to use crunchy peanut butter for added texture.
Unsalted Butter (4 tablespoons) – Enhances the creaminess of the peanut butter layer; margarine may work in a pinch.
Powdered Sugar (1 cup) – Sweetens the peanut butter layer and creates a smooth texture; no substitutions recommended here.
Pinch of Salt – Essential for balancing the sweetness of the peanut butter layer.
Vanilla Extract (1 teaspoon) – Adds depth to the flavor; always opt for pure vanilla extract for the best results.

For the Ganache
Semisweet Chocolate Chips (1 1/2 cups) – The main component for that luscious ganache; substitute with dark chocolate chips for a richer flavor.
Heavy Cream (3 tablespoons) – Creates a smooth ganache; coconut cream can be used for a dairy-free option.

Step‑by‑Step Instructions for Buckeye Brownies

Step 1: Prepare the Brownies
Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper for easy removal. If using a brownie mix, follow the package instructions to prepare the batter and pour it into the pan. Bake for 25-30 minutes until a toothpick inserted comes out with a few moist crumbs. Once baked, remove the brownies from the oven and let them cool completely on a wire rack.

Step 2: Make the Peanut Butter Layer
In a mixing bowl, combine ½ cup of creamy peanut butter and 4 tablespoons of room-temperature unsalted butter. Use an electric mixer to beat them together until the mixture is smooth and creamy, about 2-3 minutes. Gradually add 1 cup of powdered sugar, a pinch of salt, and 1 teaspoon of vanilla extract, mixing until fully incorporated. Spread this rich peanut butter layer evenly over the cooled brownies for a decadent treat.

Step 3: Prepare the Chocolate Ganache
In a microwave-safe bowl, add 1 ½ cups of semisweet chocolate chips and 3 tablespoons of heavy cream. Microwave in 30-second increments, stirring in between until the chocolate is fully melted and smooth, which should take about 1-2 minutes total. Once properly melted, pour the ganache over the peanut butter layer, gently spreading it out to cover the surface completely.

Step 4: Chill and Serve
Place the assembled Buckeye Brownies in the refrigerator and chill for at least 1 hour to allow the ganache to set properly. Once set, take them out of the fridge and carefully lift the brownies out of the pan using the parchment paper. Slice them into squares using a sharp knife, and prepare to serve these irresistible Buckeye Brownies at your next gathering or enjoy them as a sweet indulgence at home!

How to Store and Freeze Buckeye Brownies

Room Temperature: Store these brownies in an airtight container at room temperature for up to 3 days. Keep them in a cool, dry place to maintain their texture.

Fridge: For longer-lasting freshness, refrigerate the Buckeye Brownies in an airtight container for up to a week. This helps keep the ganache and peanut butter layer creamy.

Freezer: You can freeze the brownies for up to 3 months! Wrap each slice in plastic wrap, then store them in a freezer-safe bag or container to preserve their delightful flavors.

Reheating: Enjoy them cold or let them sit at room temperature for a few minutes. If you prefer them warm, microwave for about 10-15 seconds for a gooey treat!

Expert Tips for Buckeye Brownies

  • Cool Completely: Allow the brownies to cool completely before spreading the peanut butter layer; otherwise, it may melt and become a gooey mess.

  • Parchment Magic: Use parchment paper to line your pan for easy removal, preventing any heartbreaking stuck brownies.

  • Chill for Setting: Make sure to refrigerate the brownies long enough for the ganache to set. This helps create clean cuts for those perfect squares!

  • Melt with Care: When melting chocolate for ganache, stir often to avoid burning. Microwaving in short bursts helps keep the chocolate smooth.

  • Experiment with Nut Butters: Feel free to swap the creamy peanut butter for almond butter or sun butter to accommodate different tastes while keeping the delightful essence of Buckeye brownies.

Buckeye Brownies Recipe FAQs

What type of peanut butter is best for the peanut butter layer?
I always recommend using creamy peanut butter for a smooth and rich layer. If you prefer some crunch, feel free to switch it up with chunky peanut butter, which adds texture and a delightful surprise in every bite!

How do I store leftover Buckeye Brownies?
Keep your brownies in an airtight container at room temperature for up to 3 days. If you want them to last a bit longer, refrigerate them for up to a week. Just make sure they’re stored properly to keep that rich taste and texture intact.

Can I freeze Buckeye Brownies? How?
Absolutely! To freeze these brownies, wrap each square tightly in plastic wrap. Then, place them in a freezer-safe container or bag. They’ll keep well for up to 3 months. When you’re ready to enjoy them, simply let them thaw in the refrigerator overnight or at room temperature for a couple of hours.

What should I do if my chocolate ganache is too thick?
If your ganache is too thick to spread, that’s no problem! Simply add a bit more heavy cream to the mixture and gently reheat it in the microwave in 10-second increments, stirring until it’s smooth and easily spreadable again. This will ensure you have that glossy finish!

Are these brownies suitable for those with nut allergies?
If you’re accommodating nut allergies, I suggest substituting the peanut butter with sunflower seed butter or another nut-free option like soy nut butter. Just keep in mind that the flavor will slightly change, but the brownies will still be deliciously indulgent!

Can I use a different chocolate type for the ganache?
You sure can! While semisweet chocolate chips are the classic choice, you can use dark chocolate chips for a richer flavor. If you prefer milk chocolate, that’s also an option—just adjust the sweetness if needed, as milk chocolate tends to be sweeter than semisweet.

These Buckeye Brownies are sure to satisfy your sweet cravings! Enjoy making them and sharing the joy with loved ones.
