This Buckeye Bars recipe is the ultimate treat for anyone who loves the classic combination of peanut butter and chocolate. I honestly don’t think I’ve ever met a single person who doesn’t melt a little at the thought of rich, creamy peanut butter paired with smooth chocolate.
If Reese’s cups disappear instantly in your house, prepare for these Buckeye Bars to vanish even faster. With a thick, sweet peanut butter base and a glossy layer of chocolate on top, they’re the kind of dessert that never lasts longer than a day—especially if you have kids, friends, or family hanging around.
I highly suggest making a double batch for parties or holidays. They’re ridiculously easy, no-bake, and always a crowd-pleaser!

Ingredients for Buckeye Bars
Scroll to the recipe card for exact measurements.
Creamy Peanut Butter: Creates a smooth, velvety base. Prefer crunch? Use crunchy peanut butter instead.
Butter: Softens the peanut butter mixture and helps create a rich, spreadable texture. You’ll use a bit more in the chocolate layer, too.
Salt: Balances sweetness and boosts flavor.
Vanilla Extract: Enhances both the peanut butter and chocolate layers.
Powdered Sugar: Sweetens and thickens the peanut butter mixture until it forms a perfect soft dough.
Semi-Sweet Chocolate: The ideal balance of sweet and rich. Substitute with dark or milk chocolate if preferred.

See recipe card for full instructions.
Peanut Butter Layer
- Line an 8×8 pan with parchment paper.

Chocolate Layer
- Add chocolate chips and butter to a microwave-safe bowl.
- Microwave in 30-second intervals, stirring between each, until fully melted.
- Pour the chocolate over the peanut butter layer and smooth it out with an offset spatula.
Finishing
- Refrigerate for 10–20 minutes, just until the chocolate has set but isn’t rock-hard.
