Prep: 15 min · Cook: 8 min · Yield: 8 · Method: Air Fryer
Ingredients
- 1 cup sourdough discard
- 1 cup all-purpose flour
- 0.333 cup granulated sugar
- 1 large egg
- 1 teaspoon baking powder
- 0.5 teaspoon ground cinnamon
- 0.25 teaspoon salt
- 2 tablespoons butter
- 0.5 cup granulated sugar
- 1 teaspoon ground cinnamon
Cooking instructions
- Preheat the air fryer to 350°F for 3 minutes. Lightly grease the basket or fit it with perforated parchment made for air fryers. (about 3 min) — 350°F
- Whisk the sourdough discard, egg, and melted butter until smooth. In a separate bowl, stir together the flour, 1/3 cup sugar, baking powder, 1/2 teaspoon cinnamon, and salt. Add the dry ingredients to the discard mixture and stir just until a soft, slightly sticky dough forms. (about 5 min)
- Turn the dough onto a lightly floured surface and pat it to about 1/2 inch thick. Cut 8 small rounds with a 2 1/2-inch cutter, then cut out the centers with a 1-inch cutter. Re-roll scraps once if needed. (about 5 min)
- Arrange the rings in the air-fryer basket in a single layer, leaving space between them. Air-fry until puffed, lightly browned, and cooked through, 7 to 9 minutes, turning halfway if your air fryer browns unevenly. (about 8 min) — 350°F
- Melt the butter for the coating. Stir together 1/2 cup sugar and 1 teaspoon cinnamon. Brush the warm donuts with melted butter, then toss them in the cinnamon sugar. Serve warm. (about 3 min)
