Reese's Puffs (formerly Reese's Peanut Butter Puffs) is a corn-based breakfast cereal manufactured by General Mills inspired by Reese's Peanut Butter Cups. At its launch in May 1994 the cereal consisted of grain puffs flavored with chocolate and peanut butter. Later, the format was revised to be a mixture of chocolate puffs and peanut butter puffs. Artificial flavours and food coloring was removed in 2015 in response to consumer demand.
