Baby Ruth King Size Chocolate Bar by Nestle. One of the world's first, Baby Ruth is a chocolate-covered bar made of peanuts, caramel and nougat. This exceedingly chewy candy bar is not named after a famous baseball player, but after the daughter of President Cleveland. Whoever it is named after, Baby Ruth is delicious. Each king size bar is 3.7 ounces and there are 18 bars per box.
