greek yogurt donuts (lemon raspberry, air fryer)

0 Preheat your air fryer to 350°F if needed.
1 In a large bowl, whisk together the [wprm-ingredient text="3/4 cup plain Greek yogurt" uid="1"], [wprm-ingredient text="1 large egg" uid="2"], [wprm-ingredient text="2 tablespoons maple syrup" uid="3"],  half the lemon zest, and lemon juice until smooth. It's easier to zest a full lemon, so zest it first, half in your large bowl for the dough and half in a small bowl for the sugar topping.
2 Add the [wprm-ingredient text="1 1/4 cups all-purpose flour, plus 1-2 tablespoons more as needed" uid="5"], [wprm-ingredient text="2 teaspoons baking powder" uid="6"], [wprm-ingredient text="1/4 teaspoon baking soda" uid="7"], and [wprm-ingredient text="1/2 teaspoon salt. Mix " uid="8"]until a soft dough forms. It will be slightly sticky. If the dough is too sticky to roll, add flour one tablespoon at a time until it holds its shape.
3 Gently fold in the [wprm-ingredient text="1/2 cup frozen raspberries" uid="9"] with a spatula. A few rough folds - you want them distributed but not smashed.
4 Divide the dough into 6 equal portions. With lightly oiled hands, roll each piece into a smooth ball.
5 Spray the air fryer basket with olive oil. Place the donuts in the basket with at least half an inch of space between each. Spray the tops lightly.
6 Air fry at 350°F for 10-12 minutes, until the donuts are set on the outside and a toothpick inserted in the center comes out clean. Work in batches if needed.
7 While the donuts cook, mix the [wprm-ingredient text="1/3 cup granulated sugar" uid="11"] with the remaining lemon zest in a shallow bowl. Rub the zest into the sugar with your fingers until fragrant.
8 When the donuts come out, let them rest 1-2 minutes. Spray with olive oil, then roll in the lemon sugar while warm. Eat immediately or let cool on a wire rack.
