After finding success with his establishment Charm City Cakes and reality stardom with Ace of Cakes, Duff's business life only continued to grow. He has written three cookbooks: Ace of Cakes: Inside the World of Charm City Cakes, Duff Bakes: Think and Bake Like a Pro at Home, and Super Good Baking for Kids.

In September 2023, Duff entered into another contract with Food Network, meaning fans can expect the repeat judge to keep making appearances on their favorite cooking shows. The contract is a multi-year deal, keeping Duff tied to the television chef world for a good while.

Duff's Baking Championship is expected to stay on the air alongside a seasonal show called The Elf on the Shelf: Sweet Showdown, according to Variety. With more on the horizon, Duff will need to keep getting bigger and better with his cake journey.

“To continue to be a part of the Food Network family after all these years is awesome. For me as a chef, Food Network is home," Duff said. Baking for, inspiring, educating and entertaining audiences is what motivates me and being able to do this for many years to come is a dream come true.”
