It takes just 5 simple ingredients to make these No-Bake Peanut Butter Buckeye Bars! They are rich, creamy, and delectable, and you don't even need an oven!
Buckeye Balls are a famous treat from Ohio! Little balls of sweet peanut butter are dipped in chocolate. They look like the nut from Ohio's state tree, the Buckeye tree!
These chocolate peanut butter balls were a personal favorite of mine because I am a huge chocolate peanut butter lover! The trouble is that they are a pain to make!
Good news! This easy Buckeye Bars recipe takes such little effort, it will become a favorite for all chocolate peanut butter fans! They are even easier than my super simple peanut butter no-bake cheesecake!

See the recipe card at the bottom of this post for the full list of ingredients, including measurements.
Peanut Butter - Use regular creamy peanut butter like Jif or Peter Pan. If you use natural or homemade peanut butter then the peanut butter layer will not be as creamy.
Butter - Salted or unsalted butter both work equally well in this recipe. Make sure that the butter has been softened to room temperature so that it blends well with the peanut butter and sugar.
Powdered Sugar - Also called confectioners' sugar, powdered sugar sweetens the bars and also provides structure to the peanut butter layer. Some like to replace ½ cup of the powdered sugar with brown sugar, which adds a hint of molasses flavor.
Vanilla Extract - Adds depth of flavor and makes these bars taste like you really worked hard to make them!
Chocolate - A high-quality chocolate will make the best bars. I like Guittard or Ghiradelli chocolate chips. You can also use semi-sweet baking bars. Substitute dark chocolate for semi-sweet chocolate if you prefer.
Step One: Make the Peanut Butter Layer
- Combine peanut butter, butter, powdered sugar, and vanilla extract in a large bowl and beat until smooth.
- This can be done by hand if you have a strong arm, but it is a very thick dough and much easier to do with an electric mixer.
Step Two: Press Into Pan
- Line a 9x13-inch pan with parchment paper. You could also use wax paper or heavy-duty aluminum foil. Make sure the sheet is large enough that you can grab it to remove the bars from the pan.
- Press the peanut butter mixture firmly into the bottom of the pan with your hands.
Step Three: Make the Chocolate Mixture
- Melt chocolate chips and 1 tablespoon of butter in a microwaveable bowl by microwaving for about a minute and a half. Stir the chocolate about every 30 seconds.
- Pour the melted chocolate over the peanut butter layer.
- Use a beveled spatula to spread evenly.
Step Four: Refrigerate the Bars
- Place the bars in the refrigerator for about an hour to set the chocolate.
- Remove the bars from the refrigerator and lift up on the parchment paper to remove the bars from the pan.
- Place them on a cutting board and use a sharp knife to slice them into squares. Wipe the knife off after each cut for clean lines. For triangles, cut each square across diagonally.
Buckeye Bar Variations
- Thick Chocolate Layer - I prefer a thick layer of peanut butter with a thin layer of chocolate, but if you would like a thicker layer of chocolate then you can double the amount of chocolate used.
- Sweetened Condensed Milk - For a fudgy chocolate layer, add a 14-ounce can of sweetened condensed milk to the chocolate chips before microwaving.
- Rice Krispies - Turn these into crispy buckeye bars by adding 4 cups of Rice Krispies to the peanut butter mixture.
- Graham Crackers - Adding graham crackers make these a little more like cookie bars versus candy. Mix 1 ½ cups of fine graham cracker crumbs into the peanut butter mixture.
Refrigerate your Buckeye Bars in an airtight container and they will keep for up to a month!
Yes, Buckeye Bars freeze great! Place the cut bars in a single layer on parchment paper and freeze for one hour. Remove from the parchment and transfer to an airtight storage container or freezer bag. They will keep for up to 4 months. Thaw for 24 hours in the refrigerator before serving.
Most Buckeye Bars are naturally gluten-free. However, some powdered sugar brands include a starch ingredient that has gluten. If you are sensitive to gluten then it is important to always check your labels.
If you try to cut the bars after the chocolate has fully set then it will crack instead of giving you straight lines. For best results, refrigerate your bars for 30-60 minutes then cut them into squares. Return the cut bars into the refrigerator for an additional hour, or until ready to serve.
Yes, cut each ingredient amount in half. The smaller version of this recipe will fit in a 9x9 square pan.
