The Easy-Bake Oven is a working toy oven introduced in 1963 by Kenner and currently manufactured by Hasbro. The original toy used a pair of ordinary incandescent light bulbs as a heat source; current versions use a true heating element. Kenner sold 500,000 Easy-Bake Ovens in the first year of production. By 1997, more than 16 million Easy-Bake Ovens had been sold.
