How to Make This Buckeye Bars Recipe

For the Peanut Butter Layer

STEP TWO: Using a silicone spatula or an offset spatula, evenly spread the chocolate mixture over the peanut butter layer. Cover with aluminum foil or plastic wrap and chill the refrigerator for 15-20 minutes.

STEP THREE: Remove the baking dish from the refrigerator. Carefully slice the buckeye bars with a sharp knife into 15 (2½-inch x 3-inch) pieces. Cover the baking dish and return the bars to the refrigerator to continue chilling for an additional 1 hour and 45 minutes. 

PRO TIP:

You can let the bars chill for the full 2 hours before slicing, but the chocolate layer may crack and not be as pretty as pre-slicing after chilling for 15 to 20 minutes.

STEP FOUR: Remove the bars from the dish by the parchment paper. Serve immediately.

PRO TIP:

You may need to carefully re-slice the bars before serving.

FREQUENTLY ASKED QUESTIONS

Why are these called buckeyes?

This confection is called a buckeye because the finished product with its chocolate exterior and a layer of peanut butter recreates the buckeye candy that resembles the nuts from the buckeye tree which is native to Ohio.

Can I freeze these bars?

These peanut butter treats can be frozen in an airtight container for up to three months.

Can I use natural peanut butter in this recipe?

These no bake peanut butter bars are best made with regular peanut butter. The oils of natural peanut butter tend to separate and may not give you the consistency you want for this recipe.

    I have only made the traditional buckeye candies. They are standard fare at Christmas time for our family. I need to try the bars, since it would be so much quicker without dipping all the candies individually in chocolate. Thanks for the great recipes!
