Ingredients You’ll Need

Every ingredient in these No Bake Peanut Butter Buckeye Bars has a role to play—from creating that addictive, fudgy peanut butter base, to providing the glossy chocolate top. Gather them up and let’s celebrate how just a few pantry staples can create something truly crave-worthy.

• Butter (1/2 cup, softened): Adds richness and helps the peanut butter base stay perfectly smooth and sliceable.
• Creamy peanut butter (2 cups): Go for a classic creamy variety to make the filling extra luscious and traditional.
• Powdered confectioners sugar (3 1/2 cups): Sweetens and thickens the base, giving it that irresistible, melt-in-your-mouth texture.
• Vanilla extract (1 1/2 teaspoons): Adds a warm, aromatic note that bridges the peanut butter and chocolate flavors beautifully.
• Chocolate chips or chunks (2 cups or 12 ounces): Forms the luscious chocolate layer that makes each bite so decadent; semisweet works best, but use your favorite!
• Butter or coconut oil (1 tablespoon): Ensures your chocolate topping spreads easily and sets with a lovely sheen.

How to Make No Bake Peanut Butter Buckeye Bars

Step 1: Mix the Peanut Butter Base

Start out with a large bowl and add your softened butter, creamy peanut butter, powdered sugar, and vanilla extract. Using an electric mixer (or some enthusiastic arm power), blend until everything comes together smoothly. The dough will be quite thick and a bit crumbly—don’t worry, that’s just right! This texture will help the bars hold their shape, and it signals that all that sugary peanut goodness is ready for the next step.

Step 2: Press Into the Pan

Line a 9×13-inch pan with parchment paper; make sure you have plenty of overhang, so lifting your bars out later is a breeze. Scrape the peanut butter dough into the lined pan and use your hands or a spatula to press it down very firmly and evenly. Taking a minute here ensures your layers look gorgeous and don’t crumble when you slice them later.

Step 3: Melt the Chocolate

Pop your chocolate chips or chunks and that remaining pat of butter (or coconut oil) into a microwave-safe bowl. Microwave in short, 30-second bursts, stirring well between each, until everything is melty and smooth. Usually a minute and a half does the trick, but go slow and don’t scorch the chocolate. If you don’t have a microwave, a double boiler on the stove works perfectly, too!

Step 4: Top and Chill

Pour or scrape all your glorious melted chocolate over the peanut butter base, then spread it gently into every corner. Set the pan on the counter for about 30 to 60 minutes, until the chocolate is set but still sliceable—you’re looking for a glossy finish. When ready, use those parchment “handles” to lift out the entire slab, and transfer to a cutting board so you can slice gorgeous squares.

Step 5: Refrigerate Before Serving

For the ultimate clean-cut bars and the best texture, move the slab to the refrigerator for at least one hour before serving. Chilling firms up the chocolate and makes slicing even easier—plus, it’ll give you that satisfying snap with every bite of your No Bake Peanut Butter Buckeye Bars.

How to Serve No Bake Peanut Butter Buckeye Bars

Garnishes

Dress up your No Bake Peanut Butter Buckeye Bars with a sprinkle of flaky sea salt, a dusting of powdered sugar, or a few mini chocolate chips scattered on top while the chocolate is still warm. You could even drizzle on some melted peanut butter for a gourmet finish.

Side Dishes

Although these bars are standouts solo, they’re absolute showstoppers paired with a tall glass of cold milk, a cup of coffee, or a scoop of vanilla ice cream. Try adding fresh strawberries or a fruit salad alongside to balance the richness—your guests will love the combo!

Creative Ways to Present

Get festive by cutting your No Bake Peanut Butter Buckeye Bars into fun shapes with cookie cutters (think hearts or stars for special occasions). Stack bars neatly on a platter for parties, or wrap individual pieces in parchment and tie with twine for incredible edible gifts.

Make Ahead and Storage

Storing Leftovers

Store any leftover bars in an airtight container in the fridge for up to a week. The cool temperature keeps the chocolate snappy and the peanut butter filling perfectly dense and fudgy.

Freezing

No Bake Peanut Butter Buckeye Bars are freezer-friendly! Wrap each bar tightly in plastic wrap and then place in a freezer-safe bag or container—they’ll keep beautifully for up to two months. Let them thaw at room temperature for about 30 minutes before serving.

Reheating

You won’t need to reheat these, but if you like your bars softer, let them stand at room temperature for 10-15 minutes before enjoying. The peanut butter layer becomes silkier, while the chocolate stays satisfyingly crisp.

FAQs

Can I use crunchy peanut butter instead of creamy?

Absolutely—crunchy peanut butter will add a lovely texture to the bars, giving each bite a little extra satisfaction. Just be aware that the bars may be a bit more crumbly, but just as delicious!

Do I have to use a 9×13-inch pan?

You can use any similarly sized pan you have on hand, or even make thicker bars in a smaller pan. Just remember, the chilling times may vary slightly if your layers are thicker.

What’s the best way to cut smooth, clean bars?

For the cleanest slices, chill your No Bake Peanut Butter Buckeye Bars well and use a sharp knife dipped in hot water (then wiped dry). Cut firmly but smoothly for the most professional-looking results.

Can I make these bars dairy-free or vegan?

Yes! Swap the butter for your favorite vegan substitute (or coconut oil), and use dairy-free chocolate chips. Make sure your peanut butter and confectioners sugar are vegan as well, and you’re good to go.

Why is my chocolate layer cracking when I cut the bars?

If the bars are too cold when you slice them, the chocolate can crack. Let them sit at room temperature for 10 to 15 minutes before cutting with a sharp, warm knife—this helps prevent breakage.

Final Thoughts

Whether you’re looking for a sweet homemade gift or a quick dessert fix, No Bake Peanut Butter Buckeye Bars are irresistibly simple and satisfyingly decadent. Don’t be surprised if they disappear faster than you expect—make an extra batch and spread the peanut butter-chocolate joy!
