Ingredients You’ll Need
The beauty of this Buckeye Bars Recipe is how few ingredients it calls for, yet each one plays an essential role in building layers of texture and flavor. From the creamy peanut butter foundation to the silky chocolate finish, every element is simple but crucial for that perfect bar.
- 8 tablespoons salted sweet cream butter, softened: Adds richness and helps create that smooth peanut butter mixture texture.
- 3 cups creamy peanut butter: The star ingredient that brings the signature nutty flavor and creamy consistency.
- 2 teaspoons pure vanilla extract: Enhances sweetness and adds a warm, fragrant note.
- 4 cups powdered sugar: Provides necessary sweetness and helps the mixture firm up.
- 1 (12-ounce) package semi-sweet chocolate chips: Melts into a silky ganache with just the right bittersweet balance.
- 2 tablespoons vegetable oil: Keeps the chocolate ganache smooth and glossy.
How to Make Buckeye Bars Recipe
Step 1: Create the Peanut Butter Base
Start by blending the softened butter and creamy peanut butter together in a large mixing bowl until the mixture becomes smooth and creamy. This creamy base is what makes the bars hold together while delivering that irresistible peanut buttery flavor.
Step 2: Sweeten and Firm Up the Mixture
Next, stir in the vanilla extract followed by the powdered sugar. The powdered sugar not only sweetens but gives the mixture a firmer texture, allowing it to hold its shape when pressed into the pan. Be sure to mix until everything is evenly combined and the mixture feels firm but spreadable.
Step 3: Press Into the Pan
Grease a 9×13-inch baking pan lightly, then press the peanut butter mixture evenly into the pan. Take your time to spread it smoothly so the thickness is consistent throughout, which helps the bars set perfectly.
Step 4: Make the Chocolate Ganache
In a heatproof bowl set over low heat, melt the semi-sweet chocolate chips together with the vegetable oil, stirring constantly until you have a glossy, silky sauce. This ganache will be the decadent topping that makes these bars truly special.
Step 5: Spread the Ganache Over the Base
Pour the warm ganache evenly over the peanut butter layer, spreading it out with a spatula so every inch is covered in rich chocolate. This contrast between peanut butter and chocolate is what gives the Buckeye Bars their classic charm.
Step 6: Chill Until Set
Place the pan in the refrigerator and chill the bars for about 2 hours, or until the chocolate has fully set and become firm to the touch. Patience here ensures clean cuts and a perfect texture.
Step 7: Cut and Enjoy
Once chilled, remove the pan from the fridge and cut into approximately 15 squares. These bars are ready to serve, share, and savor!
How to Serve Buckeye Bars Recipe

Garnishes
While these bars are delicious as they are, a light dusting of powdered sugar or a sprinkling of chopped peanuts on top before the chocolate sets can add an extra touch of flair and texture. For a bit of contrast, a drizzle of white chocolate makes an elegant swirl accent.
Side Dishes
Buckeye Bars make a fantastic companion to a cold glass of milk or a hot cup of coffee. If you’re serving them at a party or gathering, consider pairing with fresh fruit like sliced strawberries or crisp apple slices to balance out the richness.
Creative Ways to Present
For an eye-catching presentation, arrange the bars on a platter with some mini peanut butter cups or chocolate chips scattered around. Wrapping individual bars in festive parchment paper or placing them in decorative cupcake liners elevates their appeal for gifting or party treats.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Buckeye Bars in an airtight container in the refrigerator to maintain freshness and firmness. They will stay perfectly delicious for up to one week, making them a great make-ahead treat.
Freezing
If you want to enjoy these bars later, freezing is a smart option. Wrap each bar individually in plastic wrap and place them in a freezer-safe container. They can be frozen for up to three months without sacrificing flavor or texture.
Reheating
To bring frozen bars back to edible perfection, thaw them overnight in the refrigerator. You can also let them sit at room temperature for about 30 minutes before serving. Avoid microwaving as it may melt the chocolate ganache unevenly.
FAQs
Can I substitute natural peanut butter in this Buckeye Bars Recipe?
Natural peanut butter can be used, but because it has a different oil content and texture, the mixture may be softer and harder to set. If you decide to use it, consider chilling the mixture longer before pressing it into the pan.
Is it possible to make these bars vegan?
Yes! To veganize this Buckeye Bars Recipe, substitute the butter with a plant-based vegan butter and ensure the chocolate chips are dairy-free. Use powdered sugar that is vegan-friendly as well. The texture and flavor should remain close to the original.
What if I want a thicker peanut butter layer?
You can increase the peanut butter and powdered sugar quantities proportionally to build a thicker base, just make sure to keep the texture firm enough to hold together when cutting. Adjust the pan size if needed to maintain bar thickness.
Can I use dark chocolate instead of semi-sweet chocolate chips?
Absolutely! Dark chocolate chips will give the bars a slightly more intense chocolate flavor and less sweetness, which some people prefer. Just be sure to melt them gently to avoid burning.
How long do these bars last at room temperature?
Buckeye Bars are best stored in the refrigerator because of the peanut butter and chocolate ganache. At room temperature on a warm day, they may become too soft. If you do keep them out during serving, try to limit it to a few hours.

Now that you have this delightful Buckeye Bars Recipe at your fingertips, there’s really no excuse not to whip up a batch and treat yourself or your loved ones.
