* 1/2 cup of granulated sugar.

* 1 tbsp of ground cinnamon.

* 1 (16.3-ounce) can flaky large biscuits.

* Olive oil spray or coconut oil spray.

* 4 tbsp of unsalted butter, melted.

* 1 cup of powdered sugar.

* 2 oz. of milk.

* 1/2 tsp of pure vanilla extract.

* 3/4 cup of powdered sugar.

* 1/4 cup of unsweetened coca powder.

* 3 tbsp of milk.

1. Line a baking sheet with parchment paper. Combine sugar and cinnamon in a shallow bowl; set aside.

2. Remove the biscuits from the can, separate them, and place them on the baking sheet. Use a 1-inch round biscuit cutter (or similarly-sized bottle cap) to cut holes out of the center of each biscuit.

3. Lightly coat an air fryer basket with olive or coconut oil spray (do not use nonstick cooking spray such as Pam, which can damage the coating on the basket).

4. Place 3 to 4 donuts in a single layer in the air fryer (they should not be touching). Close the air fryer and set to 350°F. Cook, flipping halfway through, until the donuts golden-brown, 5 to 6 minutes total. Transfer donuts place to the baking sheet. Repeat with the remaining biscuits. You can also cook the donut holes — they will take about 3 minutes total.

5. Brush both sides of the warm donuts with melted butter, place in the cinnamon sugar, and flip to coat both sides. Serve warm.
