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.[1][2] At its launch in May 1994[3] 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.[4]Artificial flavours and food coloring were removed in 2015 in response to consumer demand.[5][6] [Wikipedia]
