Join Chris Morocco in the Bon Appétit Test Kitchen as he makes lemony glazed yonuts (yes, that’s a Greek yogurt doughnut). We set out to make a Greek doughnut, we really did. We tried and we tried, and when it wasn’t working, we switched to Greek yogurt. Adding yogurt to the batter for these cake doughnuts made them light, tangy, and rich, and gave us a dough that was easy to work with.
