Make your simple syrup first by adding the sugar and water in a small pot and turning on medium high heat. Stir every so often until the sugar dissolves. Once the syrup has boiled, remove from the heat and set aside.
On a cutting board, remove the biscuits from the can. Use your small cookie cutter to make holes in the center of the biscuits so they resemble donuts. If you use an oddly shaped cutter, use your hands to shape the inner part of the donut into a circle.
Start the air fryer at 350 degrees. let sit for a couple minutes before adding the biscuits.
While you wait make the glaze by adding the powdered sugar, milk and simple syrup to a mixing bowl and whisk together. Set aside.
Put the biscuits into the air fryer where they aren't touching and bake them for 5 minutes.
When done, remove from the air fryer and let sit for 30 seconds. Then dip the donuts face down into the set aside glaze and lie them back down on a plate, parchment paper or even a rack with a dripping plate underneath.
Eat them warm just like Krispy Kreme Donuts that just came out or seal in an airtight container for later!
