Sink your teeth into this franchise's signature glazed doughnut, and don't be afraid to indulge in its many varieties of deep-fried perfection.. In Short In 1937, Vernon Rudolph brought a secret recipe from a French chef to North Carolina, creating the infamous irresistible treat and starting a glazed doughnut revolution. These scrumptious doughy delights are brushed with a sugar coating, and have been know to cause even the most dedicated hard-bodies to temporarily abandon their diet. Evolving past the original glaze recipe, today customers can now choose from a variety of lip smacking treats, from apple fritter to New York cheesecake doughnuts. The international company still holds to its roots, providing welcoming and helpful service while perfecting its craft at making melt-in-your-mouth masterpieces.
