How to Make It
Preheat the oven to 350°F. Spray three 6-count doughnut pans with nonstick cooking spray.
Peel the sweet potatoes and cut them into 1-inch cubes. Put the sweet potatoes in a large saucepan and add cool water to cover by 1 inch. Set the pan over medium-high heat and bring to a boil. Reduce the heat to low to maintain a gentle simmer and cook until the sweet potatoes are fully tender about 15 minutes. Drain the sweet potatoes, reserving the cooking liquid.
Make the glaze: Put the confectioners’ sugar in a bowl, add the orange juice, and stir until all of the sugar is dissolved and the glaze is smooth and pourable.
