The store will sell freshly baked cookies from the Colorado-based shop, known for its soft quarter-pound cookies and other mountain-style treats.
The location at 107 W. Louisiana St., McKinney, is the first Texas store for the business.
The menu will have more than 15 flavors of cookies, all of which are made on location and baked fresh each day, said Merry Moch, one of the owners. Featured flavors will include s'mores, blueberry oat, salted caramel, turtle and traditional flavors, such as oatmeal raisin and peanut butter. www.marysmountaincookies.com
