Known for: Voodoo-inspired raised donuts in flavors like S'Mores, Huckleberry Day Dream, Maple Bacon and a Dr. Pepper glaze, sold from 4 a.m. batches until sell-out on Billings' West End.

2 locations

Childhood friends Klay Welter and Trevan Sparboe from Lockwood spent four years perfecting a home donut recipe before opening Proof on May 14, 2022, in the former Kal's Chicken Coop space at 805 24th St. W., running donuts in the morning and the chicken restaurant later in the day.

Open since 2022

Founded by Klay Welter and Trevan Sparboe; the Billings Gazette reported the business was listed for sale, so current ownership should be confirmed.
