Start preheating the air fryer to 350F. Spray two ramekins with non stick cooking spray and set aside.
In a blender, blend the old fashioned oats, baking powder, banana, milk, peanut butter, honey, salt, cinnamon, vanilla extract until smooth. Stir in the chocolate chips.
1/2 cup old fashioned oats, 1/2 tsp baking powder, 1/2 large banana, 1/4 cup milk, 1 tbsp peanut butter, 1 tbsp honey, 1/4 tsp salt, 1/4 tsp cinnamon, 1/4 tsp vanilla extract, 1-2 tbsp chocolate chips
Divide the batter into the two ramequins, Pour enough to fill 2/3 of the ramequins in each one, and bake in the air fryer for 8-10 minutes.
Let the baked oatmeal cool down for 10 minutes before enjoying! Be careful the ramekins will be hot so handle with care.
Notes
How to tell when baked oats are done: the top looks dry and springs back when pressed, and a toothpick comes out with a few moist crumbs, not wet batter. Pull them while the very center still looks slightly soft, they finish setting as they cool.Air fryer time guide: two 6 to 7 oz ramekins at 350F take 8 to 10 minutes. One larger baking dish takes longer at the same temperature, so check every couple of minutes past the 10 minute mark. Air fryers vary a lot, so use the doneness cue rather than the clock the first time.For a high protein version: add a scoop of protein powder and use a whole banana instead of half. Protein powder pulls moisture out, so the extra banana keeps the texture from going dry.Storage: cover and refrigerate up to 2 days, or freeze up to 1 month. Reheat in the microwave for 30 to 60 seconds from the fridge, 60 to 90 seconds from frozen.
