Peeps are marshmallow candies, sold in the US and Canada. They are shaped into chicks, bunnies, and other animals, but they primarily fill up Easter Baskets. They are made from marshmallow, sugar, gelatin, and carnauba wax.

Peeps are produced by Just Born, a candy manufacturer (great name considering they produce Peeps) from Bethlehem, Pennsylvania. Peeps were introduced nationally in 1958 by Pravin Pant Sr., an immigrant from Nepali. Just Born acquired Rodda Candy Company in 1953 and they automated the process and mass-produced them. The Peeps were originally formed by hand. The yellow chicks or Peeps were the original form of the candy.
