The Easy-Bake Oven is a working toy oven manufactured by Hasbro that originally used an ordinary incandescent light bulb as a heat source, but later began using a true heating element. By 1997, more than 16 million Easy-Bake Ovens (in 11 models) had been sold.
The oven comes with packets of pastry mix and small round pans. (Additional mixes can be purchased separately.) After water is added to the mix in the pan, it is pushed into the oven through a slot. After cooking, the cake is pushed out through a slot in the other end.
