Scoop batter into prepared muffin pan. If I want 6 muffins I heap the batter in the muffin pan. If you want more muffins fill just to the top. I get 8 muffins that way.
Place muffin pan in the air fryer. Set to Air Fry on 400F for 5 minutes. After 5 minutes set to Bake at 350F for 10 more minutes. Check with a toothpick.
