Gather Your Ingredients: Before starting, ensure you have all the necessary dry and wet ingredients for your baked oats.

Blending the Batter: In a blender, combine all dry ingredients (such as oats and baking powder) first, then add the wet ingredients (such as milk, egg, and vanilla extract). Blend everything until you achieve a smooth batter. This process ensures that the oats are slightly broken down, contributing to a fluffy texture in the final dish.

Preheat the Air Fryer: Turn on your air fryer to preheat at 350°F (about 175°C). Preheating helps in cooking the baked oats evenly and achieving a golden-brown finish. Most air fryers will be ready to use within 3-5 minutes.

Prepare the Ramekins: Lightly spray your ramekins with non-stick cooking spray. This step prevents the oatmeal from sticking and makes the ramekins easier to clean afterward. Use a light layer of butter or oil if you don't have a non-stick spray.

Baking the Oats: Pour the blended oatmeal mixture into the prepared ramekins, filling them up to about three-quarters to allow space for the mixture to rise. Place the ramekins carefully into the air fryer basket, ensuring they are not overcrowded and air can circulate around them.

Set the Air Fryer: Adjust the air fryer's temperature to 350°F (175°C) and set the timer for 15-20 minutes. The exact baking time may vary depending on your air fryer model and the size of your ramekins. Start checking for doneness at around the 15-minute mark. The baked oats are done when they have a golden-brown top and a toothpick inserted into the center comes out clean.
