Step 1

Stir together the milk, melted butter, egg, and yeast in the bowl of a stand mixer. Add the flour, sugar, and salt and stir until a shaggy dough comes together.

Step 2

Knead on high for 3-5 minutes or until the dough is smooth and incorporated. Alternatively, mix and knead by hand for about 10 minutes.

Step 3

Gather the dough into a ball and place in a lightly oiled bowl and cover. Let rise for 2 hours, or until doubled.

Step 4

Tip the dough out onto a lightly floured work surface and roll to about 1 inch thick. Cut into doughnuts, gathering the excess dough and cutting into doughnuts (or donut holes).

Step 5

Place the doughnuts on a parchment paper lined baking sheet and brush with melted butter. Let rise for 45 minutes, or until doubled and puffy.

Step 6

While the doughnuts are rising, make the glaze by mixing together the melted butter, milk, vanilla, and powdered sugar until smooth.

Step 7

Preheat your air fryer to 350°F. Gently oil the basket and place the doughnuts, slightly spaced out, into the basket. Air fry for 3 minutes. They should will be golden brown and puffy.

Step 8

Glaze the donuts immediately and enjoy!
