AUSTIN, Texas -- Tiff’s Treats, home of the warm cookie delivery and an Austin staple, on Wednesday announced it has added to some star power.

Tennis great Andy Roddick and actress/model Brooklyn Decker have joined the cookie-making team as shareholders and brand ambassadors.

Tiff’s Treats is an Austin-based bakery and delivery chain started by Tiffany Taylor and Leon Chen in 1999. Following initial success at the University of Texas, the service was developed into a formal business. Its claim to fame is that it was the first U.S. baker to offer warm cookie delivery.

Roddick became the singles champion and world No. 1 after winning the 2003 US Open.

Decker has graced the cover of the Sports Illustrated Swimsuit Issue and has appeared in films including “Battleship” and “What to Expect When You’re Expecting.”

The couple resides in Austin.
