Jennifer Garner tries to keep her kids, Sam, Violet and Seraphina, healthy, but admits sometimes an Oreo cookie makes its way in when her ex-husband, Ben Affleck, visits.

“That would happen on such a special occasion,” she said during Vanity Fair’s Founders Fair. “It’s such a moment! Or if Ben is around, that might happen and then he gets credit for it, and I want to be like, ‘I like Oreos too! I’m fun too!’”

Garner runs the cold-pressed, organic baby food brand Once Upon a Farm.
