Ingredients for Buckeye Brownie Recipe
Okay, let’s talk ingredients, and I promise, nothing too fancy here! Just good, simple stuff that comes together like magic. Gather these in groups so you’re not running around the kitchen like I did the first time I made these.
Brownie Base
- 1 cup unsalted butter, melted (and slightly cooled so we don’t scramble those eggs!)
- 2/3 cup unsweetened cocoa powder (I use the good stuff โ it makes all the difference)
- 1 cup all-purpose flour (spooned and leveled, please โ no packed cups here)
- 2 cups granulated sugar (yes, it’s a lot, but we’re making brownies, not health food)
- 1/2 teaspoon table salt (balances all that sweetness perfectly)
- 4 large eggs, at room temperature (trust me, they incorporate so much better this way)
- 3 tablespoons pure vanilla extract (sounds like a lot, but it’s the secret to that deep flavor)
Peanut Butter Filling
- 1 1/2 cups creamy peanut butter (I’m loyal to Jif, but use your favorite)
- 3/4 cup unsalted butter, melted and cooled (don’t skip the cooling โ warm butter makes the filling runny)
- 2 teaspoons pure vanilla extract
- 3 cups powdered sugar, sifted (no lumps allowed in this silky filling!)
Ganache
- 1 package (10 oz) dark chocolate chips (semi-sweet works too if you prefer)
- 1/3 cup heavy cream (this makes the ganache soooo glossy)
Equipment Youโll Need
Donโt worry, you wonโt need any fancy gadgets for these brownies! Just grab:
- A trusty 9ร13-inch baking pan (this is my workhorse for all bar desserts)
- Parchment paper (the overhang trick makes lifting these beauties out so easy)
- A couple mixing bowls (one for brownie batter, one for peanut butter filling)
- Handheld mixer (or strong arms and a whisk if youโre feeling ambitious)
- Spatula for spreading (an offset one works magic on that peanut butter layer)
- Microwave-safe bowl for ganache (or use a double boiler if youโre fancy)
See? Nothing crazy. Just everyday tools that probably already live in your kitchen.

How to Make Buckeye Brownie Recipe
Alright, let’s get baking! I promise these come together easier than you think. Just follow these steps, and you’ll have perfect buckeye brownies every time.
Step 1: Prepare the Brownie Base
First things first, preheat that oven to 350ยฐF. Line your 9ร13-inch pan with parchment paper, leaving some overhang on the sides. This little trick will save you so much hassle later!
Now for the fun part: In a medium bowl, whisk together your melted butter and cocoa powder until it’s completely smooth. No lumps allowed! Add in the flour, sugar, and salt. Don’t worry if it looks thick and crumbly at this point; that’s totally normal.
Next, crack in those room-temperature eggs and add the vanilla. Use your mixer on low speed just until everything comes together into a smooth, glossy batter. Resist the urge to overmix, we want fudgy brownies, not cakey ones!
Spread the batter evenly in your prepared pan. Pop it in the oven for 23-25 minutes. You’ll know they’re done when a toothpick comes out with a few moist crumbs clinging to it. Trust me, you don’t want to overbake these beauties.
Step 2: Make the Peanut Butter Filling
While those brownies bake, let’s whip up that dreamy peanut butter layer. In a clean bowl, beat together the peanut butter, cooled melted butter, and vanilla until it’s completely smooth and creamy.
Now slowly add in that sifted powdered sugar, about a cup at a time, mixing well after each addition. Keep going until you’ve got a thick, spreadable consistency that holds its shape when you scoop it. If it seems too stiff, you can add a teaspoon of milk to loosen it up.
Here’s my pro tip: Drop spoonfuls of this peanut butter goodness all over the hot brownies as soon as they come out of the oven. Then gently spread it into an even layer using an offset spatula or the back of a spoon. The warmth from the brownies helps the peanut butter spread smoothly without tearing the surface.
Step 3: Assemble and Chill
Time for the chocolate finale! Make your ganache by pouring hot cream over the chocolate chips. Let it sit for a minute (patience is hard, I know), then stir until it’s completely smooth and glossy.
Pour this liquid gold over the peanut butter layer and tilt the pan gently to spread it evenly. Now comes the hardest part, pop the whole pan in the fridge for at least 2 hours to set up properly. I know it’s tempting to cut into them early, but trust me, waiting makes all the difference!
When they’re perfectly chilled, use those parchment paper handles to lift the whole slab out onto a cutting board. Slice into squares and try not to eat them all at once. Okay, who am I kidding? Go ahead and enjoy!

Tips for Perfect Buckeye Brownies
After making these brownies more times than I can count (okay fine, I keep track, it’s 37 batches!), I’ve learned all the tricks for absolute perfection:
- Don’t overmix the batter: Stir just until combined; those few flour streaks will disappear. Overmixing makes tough brownies, and nobody wants that.
- Parchment is non-negotiable: That overhang lets you lift the whole slab out cleanly. No more broken corners or stuck-on bits!
- Chill thoroughly: I know it’s hard to wait, but those 2 hours let the layers set properly. Otherwise, you’ll have peanut butter fingerprints in your ganache (ask me how I know).
- Room temp eggs matter: Cold eggs make the batter seize up. Just set them out 30 minutes before baking, easy!
Follow these simple tips and your brownies will turn out bakery-perfect every time!
Ingredient Substitutions & Variations
Listen, I’m all about sticking to the original recipe, but sometimes you gotta improvise! Here are my tried-and-true swaps that still deliver amazing results:
- Peanut butter alternatives: Crunchy peanut butter adds fun texture, or use almond butter for a twist. Just avoid natural varieties; they make the filling too runny.
- Chocolate choices: Semi-sweet chips work beautifully if dark chocolate isn’t your thing. Milk chocolate makes them extra sweet (kid-approved!).
- Flour options: Gluten-free 1:1 baking flour works perfectly here, my celiac friend couldn’t tell the difference!
- Sweetener swap: For slightly less sugar, try reducing the powdered sugar to 2 1/2 cups in the filling. They’ll still be plenty sweet!
The beauty of this recipe? It’s forgiving. Make it your own!
Storage & Serving Suggestions
These buckeye brownies keep beautifully in an airtight container in the fridge for up to 5 days (if they last that long!). I like to let them sit at room temperature for about 10 minutes before serving, just enough to take the chill off so you get that perfect fudgy texture. For parties, I arrange them on a pretty platter and watch them disappear!

Description
Buckeye Brownie Recipe is rich, layered chocolate and peanut butter bars with a fudgy brownie base, thick peanut butter filling, and silky chocolate ganache on top. They are perfect for anyone who loves the classic buckeye flavor in an easy bar dessert.
Ingredients
Brownie Base:
- 1 cup unsalted butter, melted
- 2/3 cup unsweetened cocoa powder
- 1 cup all-purpose flour
- 2 cups granulated sugar
- 1/2 teaspoon table salt
- 4 large eggs, at room temperature
- 3 tablespoons pure vanilla extract
Peanut Butter Filling:
- 1 1/2 cups creamy peanut butter
- 3/4 cup unsalted butter, melted and cooled
- 2 teaspoons pure vanilla extract
- 3 cups powdered sugar, sifted
Ganache:
- 1 package dark chocolate chips (10 oz)
- 1/3 cup heavy cream
Instructions
- Preheat your oven to 350ยฐF. Line a 9ร13-inch baking pan with parchment paper, leaving some overhang on the long sides so you can lift the brownies out easily.
- Make the brownie base: In a medium mixing bowl, whisk together the melted butter and cocoa powder until completely smooth. Add the flour, granulated sugar, and salt and whisk again; the mixture will look thick and a bit crumbly.
- Add the eggs and vanilla extract to the bowl. Using a handheld mixer on low speed, mix just until the batter is smooth and evenly combined. Do not overmix.
- Spread the brownie batter evenly into the prepared pan. Bake for 23 to 25 minutes, or until a toothpick inserted near the center comes out with a few moist crumbs.
- While the brownies bake, make the peanut butter filling. In a clean bowl, use a handheld mixer on medium-low speed to beat together the melted, cooled butter, creamy peanut butter, and vanilla extract until smooth.
- Turn the mixer to low and add the sifted powdered sugar, about 1 cup at a time, mixing after each addition. Continue until the mixture is thick, smooth, and spreadable.
- Make the ganache: Place the dark chocolate chips in a small heat-safe bowl. In a separate microwave-safe bowl, heat the heavy cream for 50 to 60 seconds, until it just begins to bubble. Pour the hot cream over the chocolate chips and let sit for 1 to 2 minutes, then stir until the mixture is completely smooth and glossy.
- Assemble the bars: As soon as the brownies come out of the oven, drop spoonfuls of the peanut butter filling over the hot brownie layer. Use a spoon or offset spatula to gently spread it into an even layer without tearing the brownie.
- Pour the warm ganache over the peanut butter layer and spread it evenly to cover the surface.
- Place the pan in the refrigerator for about 2 hours, or until the ganache is firm and the layers are set.
- Use the parchment overhang to lift the chilled slab of brownies out of the pan and onto a cutting board. Slice into 12 even bars and serve.
Notes
- Store the brownies in an airtight container in the refrigerator for up to 5 days.
- For best results, use room temperature eggs.
- You can substitute dark chocolate chips with semi-sweet or milk chocolate if preferred.
