The 58-year-old reality star has written In the Kitchen with Kris: A Kollection of Kardashian-Jenner Family Favorites. The book includes her personal recipes and entertaining tips.
"I finally got so tired of sharing my recipes one by one with everybody that asked, that it just made sense to do a book and put it all together," she told Guiliana Rancic on Beyond Candid.
Jenner is often seen hosting catered parties on Keeping Up with the Kardashians, but she said cooking has always been an important part of her life.
"I think that's what I love so much about our life is that we love to celebrate, we love tradition," she shared. "[Cooking] is almost like the way that I calm down. Some people do things to relax, they'll go play golf or have a sport. Me? I'm in the kitchen. Nothing makes me happier, so I hope I can share that with everybody else."
In the Kitchen with Kris is scheduled for release October 21.
