Before beginning, please note: unless you have a large air-fryer, you will need to do this in 2 batches (2 groups of 4).
Begin by separating your crescent dough. You can either leave it in the triangle form or shape it into more of a square. Place your Oreo in the center of each dough piece and fold each corner up and over the cookie until it is fully covered. Seal closed any open areas.
Optional - place a small piece of parchment paper, big enough for each batch to be adequately spaced apart as the dough will rise & expand. But do not cover the entire bottom of the fryer as that will constrict air flow.
Cook on 350° for 8 minutes, flipping halfway through.
Once done, sprinkle with some powdered sugar and serve immediately as they taste best served hot & fresh! Enjoy!
Notes
Can also be made with cookie dough, peanut butter cups, or whatever filling your heart desires!
