Ingredients You’ll Need

Here’s the beauty of Best-Ever Buckeye Brownies!: you only need a handful of familiar ingredients, but each plays a starring role. From the chewy brownie base to the creamy peanut butter layer and silky chocolate topping, nothing is wasted — and each layer packs its own punch of flavor and texture.

1 (18.4 ounce) package brownie mix: Use your favorite brand; this easy shortcut guarantees a fudgy, reliable base every time.
⅔ cup vegetable oil: Keeps the brownies extra moist and rich, never dry.
¼ cup water: Helps blend the brownie batter; use room temperature for best results.
2 eggs: The secret to holding everything together and adding a little lift.
2 cups confectioners’ sugar: Gives the peanut butter layer its smooth sweetness and creamy bite.
1 cup creamy peanut butter: For that classic buckeye flavor — make sure it’s creamy, not chunky!
½ cup unsalted butter, softened: Blended with peanut butter and sugar for luscious, spreadable texture.
1 (6 ounce) package chocolate chips: Your shortcut to a shiny, snappy chocolate layer on top.
6 tablespoons unsalted butter, softened: These melt with the chips for a glossy finish that cuts beautifully.

How to Make Best-Ever Buckeye Brownies!

Step 1: Prep the Pan

Start by preheating your oven to 350 degrees F (175 degrees C). Give your 9×13-inch baking dish a generous swipe of nonstick spray or a light buttering, so those glorious brownies will lift out without a fuss.

Step 2: Bake the Brownie Base

In a large mixing bowl, combine your brownie mix, vegetable oil, water, and eggs. Stir until just blended and smooth — lumps are the enemy of fudgy brownies! Pour the batter into your prepared pan, smoothing the top. Bake for 28 to 31 minutes, or until the edges pull slightly away from the pan. Let them cool completely before the next step; patience means perfect layers!

Step 3: Whip Up the Peanut Butter Layer

While your brownies cool, beat together the confectioners’ sugar, creamy peanut butter, and ½ cup softened butter. I use a handheld mixer, but a sturdy spatula works too. You want a creamy, dreamy mixture that’s easy to spread. Smooth this luscious peanut butter frosting evenly over the cooled brownies. Chill in the fridge for 10 minutes if it’s looking soft — this helps the next topping go on like a breeze.

Step 4: Melt and Spread the Chocolate Layer

In a small saucepan set over low heat, gently melt the chocolate chips and 6 tablespoons butter, stirring until silky. Remove from heat as soon as everything is melted and smooth — don’t let it boil. Pour the warm chocolate over the peanut butter layer and tip the pan gently from side to side, or use a spatula to get a gorgeous, even coating. Let the pan set at room temperature or pop into the fridge for quicker firming.

Step 5: Slice and Enjoy!

Once the chocolate is set, use a sharp knife (wiped clean between cuts) to slice into squares. Prepare yourself for rave reviews and requests for the recipe, because Best-Ever Buckeye Brownies! are legendary from the very first bite.

How to Serve Best-Ever Buckeye Brownies!

Garnishes

Top each square with a sprinkle of flaky sea salt to balance the sweetness, a drizzle of melted peanut butter, or a few crushed peanuts for crunch. A dollop of whipped cream on the side never hurts, and a tiny candy buckeye perched on top makes a fun nod to the classic treat.

Side Dishes

These brownies pair beautifully with a cold glass of milk, of course, but why stop there? Coffee, hot cocoa, or even a scoop of vanilla ice cream take the Best-Ever Buckeye Brownies! experience to a whole new level of indulgence.

Creative Ways to Present

For a party, cut brownies into bite-sized cubes and stack on a tiered dessert tray, or package in mini cupcake liners for grab-and-go treats. They also make a knockout edible gift — just wrap a few in parchment and tie with twine for a sweet surprise!

Make Ahead and Storage

Storing Leftovers

When the craving strikes, you’ll be glad to know Best-Ever Buckeye Brownies! keep fabulously well. Store any leftovers in an airtight container at room temperature for up to 3 days, or refrigerated if you like them extra fudgy.

Freezing

These brownies freeze beautifully — just slice, separate layers with parchment, and seal in an airtight container or freezer bag. They’ll keep their texture and flavor for up to 2 months. Thaw at room temperature (or enjoy slightly chilled straight from the freezer!).

Reheating

To bring out that just-baked flavor, microwave a brownie square for about 10 seconds. The peanut butter gets creamy, and the chocolate softens just so. For a crowd, a few minutes in a low oven revives the whole pan to perfection.

FAQs

Can I use a homemade brownie recipe instead of a mix?

Absolutely! If you have a go-to brownie recipe, simply bake it in a 9×13-inch dish and proceed with the peanut butter and chocolate layers as directed. Just make sure your base is thick and sturdy enough to support the toppings.

Can I use chunky peanut butter?

Creamy peanut butter is classic for a smooth middle layer, but if you want a bit of crunch, feel free to swap in chunky. The result may be a little less uniform when spreading, but the added texture is delicious!

How do I get clean, pretty layers when slicing?

Chill the brownies before cutting and use a sharp knife wiped clean between each cut. If you run the knife under hot water and dry it off before slicing, you’ll get even neater lines and pristine squares.

Can I add extras to the brownie batter?

You can mix in some chocolate chips, chopped nuts, or even espresso powder into the batter for a little twist. Just don’t overload the base so it stays sturdy for your layers.

Are Best-Ever Buckeye Brownies! gluten-free?

They aren’t as written, since most brownie mixes contain wheat. If you need a gluten-free batch, simply swap in a GF brownie mix and double-check your other ingredients.
