Tiff's Treats Cookie Delivery | 9,790 followers on LinkedIn. Baked to Order. Delivered Warm. | Tiff’s Treats was started in January of 1999 by two University of Texas sophomores, Leon and Tiffany. Originally run only at night for students, we started as small as you can get with $20, a cell phone, and Leon’s college apartment oven. We started simple, and our mission is still simple.
