If you’re a fan of classic peanut butter and chocolate, Buckeye Brownies are your dream dessert come true. Imagine three irresistible layers: fudge-like brownies, a creamy peanut butter filling, and a decadent chocolate ganache. Whether you’re baking for a party, a family celebration, or just because, Buckeye Brownies will quickly become your go-to treat—every bite delivers a perfect balance of flavors and textures that will have everyone begging for seconds.
Ingredients You’ll Need
It’s amazing how a handful of pantry staples come together to make such an unforgettable treat. Each ingredient in these Buckeye Brownies plays an important role—giving that signature rich chocolate base, creamy peanut butter center, and a glossy chocolate finish that’s utterly crave-worthy.
- Brownie mix (plus eggs, oil, and water as called for): Your shortcut to fudgy perfection—choose your favorite brand for the ultimate base.
- Unsalted butter, softened (1/2 cup): Adds richness and helps whip the peanut butter layer into dreamy smoothness.
- Creamy peanut butter (1 cup): The star of the show—creamy is best for that smooth, melt-in-your-mouth layer.
- Powdered sugar (2 cups): Sweetens and firms up the peanut butter filling so it slices beautifully.
- Milk (2 tablespoons): Loosens the peanut butter mixture just right for easy spreading.
- Semi-sweet chocolate chips (1 1/2 cups): Perfect for balancing the sweetness and creating that silky chocolate topping.
- Heavy cream (1/4 cup): Transforms the chocolate chips into a glossy, pourable ganache that sets up perfectly.
How to Make Buckeye Brownies
Step 1: Bake the Brownie Base
Start by preheating your oven to 350°F and lining a 9×13-inch pan with parchment or a swipe of nonstick spray—this makes getting the brownies out a breeze later. Whip up your brownie mix exactly as the package instructs, then pour the batter into your prepared pan. Slide it into the oven and bake for about 20–25 minutes, until a toothpick poked in the middle comes out mostly clean. Set the pan aside and let the brownies cool completely; patience here is key, or your next layers may melt.
Step 2: Whip Up the Peanut Butter Layer
While your brownies cool, grab a medium mixing bowl and a hand mixer (or some serious arm power!). Beat together the softened butter and creamy peanut butter until they’re smooth and fluffy. Next, gradually add the powdered sugar; this step keeps lumps at bay and lets you control the texture. Splash in the milk a bit at a time until the mixture is thick yet spreadable—it should hold its shape but glide over the brownie base easily. Gently spread this glorious peanut butter mixture over the cooled brownies, smoothing it right up to the edges for an even bite in every square.
Step 3: Prepare the Chocolate Ganache
Now for the magical crowning touch. Combine your chocolate chips and heavy cream in a microwave-safe bowl, then microwave in 30-second bursts, stirring each time, until you have a smooth, glossy chocolate ganache. Take care not to overheat; chocolate burns fast! Pour this luscious topping over the peanut butter layer, using a spatula to spread it in an even layer. The anticipation is real, but it’s nearly done!
Step 4: Chill and Set
This is the hardest part—waiting! Transfer your assembled Buckeye Brownies to the fridge for at least an hour, or until the top is fully set and no longer tacky. This helps the layers firm up, making those clean, bakery-style slices you see in the photos. Once chilled, run a sharp knife under hot water (trust me, it’s worth it) and slice into tidy squares. Prepare for applause.
How to Serve Buckeye Brownies
Garnishes
For a little extra flair, sprinkle your Buckeye Brownies with mini chocolate chips, crushed roasted peanuts, or a pinch of flaky sea salt just before the ganache sets. A drizzle of melted peanut butter or a dusting of cocoa powder adds both beauty and flavor—these little touches help make your batch feel truly special.
Side Dishes
Buckeye Brownies play fabulously with lighter, fresh sides like sliced strawberries or a bowl of mixed berries, which are a sweet-tart counterpoint to all that chocolate richness. If you’re feeling decadent, serve alongside a scoop of vanilla ice cream, or pair with a chilly glass of milk to bring back classic childhood vibes.
Creative Ways to Present
For parties or special occasions, cut your Buckeye Brownies into mini bite-sized squares and stack them high on a pretty platter. Want to impress? Layer them into parfait glasses with whipped cream and chopped peanuts for a show-stopping dessert. If you love edible gifts, wrap individual squares in wax paper and tuck them into a festive tin for the ultimate homemade treat.
Make Ahead and Storage
Storing Leftovers
Buckeye Brownies are just as dreamy the next day, making them ideal for make-ahead events. Simply cover the pan tightly with foil or transfer sliced brownies to an airtight container. They’ll keep beautifully in the fridge for up to 5 days, staying fudgy and fresh.
Freezing
If you want to plan even further ahead, you can freeze Buckeye Brownies with wonderful results. Once sliced, layer the brownies between sheets of parchment paper in a freezer-safe container. They’ll keep for up to 2 months—just let them thaw in the fridge before serving for the best texture.
Reheating
Prefer your Buckeye Brownies a little warm with that peanut butter layer just barely melty? Pop a slice in the microwave for 10–15 seconds. They’re also fantastic served cold straight from the fridge if you love a thick, chewy bite.
FAQs
Can I use homemade brownie batter instead of a boxed mix?
Absolutely! Your favorite scratch-made brownie recipe can easily replace the boxed mix for a personal touch. Just be sure your batter yields enough for a 9×13-inch pan to get the right brownie-to-topping ratio.
What kind of peanut butter is best for Buckeye Brownies?
Creamy peanut butter works best here for that classic smooth layer. Natural peanut butters can be used, but try to choose one that isn’t too oily to keep the filling firm and spreadable.
Can I skip the heavy cream in the ganache?
If you don’t have heavy cream, you can substitute with half-and-half or even whole milk, though your ganache will set a bit firmer and be slightly less rich.
How do I get super clean cuts when slicing?
For those bakery-perfect squares, chill the Buckeye Brownies thoroughly and use a sharp knife run under hot water and wiped dry between slices. This helps glide through the layers cleanly for those beautiful, Instagram-worthy edges.
Are Buckeye Brownies gluten free?
By default, most boxed brownie mixes contain wheat, but you can easily swap for a gluten-free brownie mix if needed. Double check all ingredient labels to ensure a completely gluten-free dessert.
Final Thoughts
There’s something so joyful about sharing a homemade treat, and Buckeye Brownies are the ultimate expression of peanut butter and chocolate love. Whether for a special celebration or just a cozy night in, I hope these brownies find a place in your heart—and your recipe box. Give them a try and let the happy chocolate-peanut butter memories begin!
