Buckeyes

Buckeyes are a confection made from a peanut butter fudge partially dipped in chocolate to leave a circle of peanut butter visible. Buckeyes are similar to peanut butter balls , which are completely covered in chocolate. Named for their resemblance to the poisonous nut of the Ohio buckeye tree, the state tree of Ohio, this candy is particularly popular in Ohio and neighboring states. It is common for Ohioans to make buckeyes at home, but they are also available in mail-order catalogs and candy shops.
