PROVIDENCE — Hasbro Inc. said that it will soon unveil a gender-neutral Easy-Bake Oven after meeting with a New Jersey girl who started a campaign calling on the toy maker to make one that appeals to all kids.

McKenna Pope, 13, of Garfield, N.J., got more than 40,000 signatures on her online petition at Change.org and the support of celebrity chefs, including Bobby Flay, who backed her call for Hasbro to make a gender-neutral oven and to include boys in the ads.
