In the air fryer basket, add the taiyakis, making sure that they are laying flat and not overlapping. Close the basket and set the temperature for 350 degrees for 8 minutes.
When cooking time reaches 4 minutes, pause the air fryer and open air fryer basket. Using tongs, flip the taiyakis over. Close the basket. Press the cook button to continue cooking the remaining 4 minutes. When the air fryer has finished cooking, remove taiyakis from basket and serve immediately.
