Warm cookie delivery chain Tiff’s Treats first started 22 years ago at a University of Texas at Austin apartment. Founders Tiffany and Leon Chen have grown the business to great heights since then, and now they are searching for their first-ever customer named Amy, whose last name they don’t know, to say thanks.

In honor of the company’s 22nd anniversary, Tiff’s Treats wants to reward Amy with a year of free cookies. Fans who think they know Amy are encouraged to tag her in Tiff’s Treats’ Instagram post or direct message any information to Tiff’s Treats’ Instagram, TikTok or Facebook accounts.

“She opened the door, she had blonde hair, and she was really, really nice. She thanked me for the cookies and said it was for her boyfriend, and she also tipped me $5!” says Tiff’s Treats’ co-founder Leon Chen, who delivered the cookies himself, remembering a few details about Amy, who lived at the University Towers student housing on UT Austin’s campus.

Today, Tiff’s Treats has grown to 63 stores across Texas, Georgia, Tennessee, North Carolina and soon, Oklahoma. Celebrities such as NBA legend Dirk Nowitzki, fashion designer Kendra Scott, tennis star Andy Roddick and his wife, actress Brooklyn Decker, have invested in the company.
