Baby Ruth is an American candy bar made of peanuts, caramel and chocolate-flavored nougat covered in compound chocolate. It is owned by the Swiss company Nestlé.

In 1921, the Curtiss Candy Company refashioned its Kandy Kake into the Baby Ruth. The bar was a staple of the Chicago-based company for some seven decades. Curtiss was purchased by Nabisco in 1981. In 1990, RJR Nabisco sold the Curtiss brands to Nestlé.
