Sarah Michelle Gellar takes credit for her kids' good qualities!

On Monday, ET caught up with the Buffy The Vampire Slayer star in NYC to discuss her new cookbook, Stirring Up Fun With Food, out April 4, where she took a moment to open up about her two kids with husband Freddie Prinze Jr.: 7-year-old Charlotte and 4-year-old Rocky.

"When they're good, they take after me. And when they're being naughty, they take after Freddie, obviously," the 39-year-old businesswoman joked. "Yeah, it's true."

Sorry, Freddie!

In reality, Gellar and her family are a tight-knit unit, even posing together for her new book, which she admits was a bit of a challenge.

"You know, I don't think anybody in my family, including myself, loves getting their picture taken," she admitted. "My kids don't even like the phone [camera]. They're like, 'Ugh! No more pictures. God, mom!'"

One thing the kids do like to do with their mom, however, is cook.

"I think for us, it's been a really great bonding," Gellar explained. "And I think, for my kids, it's been great to see, having an idea, starting from scratch, and actually making it into something tangible."

Gellar was also conscious of making her new cookbook accessible, as even she doesn't consider herself a "culinary whiz" like her hubby!

"He's a culinary whiz! He's a chef," she shared of Prinze Jr. "For me, it's about taking away the intimidation factor. I can't cook like him. I'm never gonna try. This is for people who -- even from novice to expert, it's just creative ways to get your creative juices flowing."

Meanwhile, Gellar recently joked about the "real reason" she married Prinze Jr.
