Blended: Add all of the ingredients to the base of a high powered blender. Blend on high for 30-60 seconds until smooth.Unblended: Add all of the ingredients to a bowl and mix until well combined.
Pour the batter into the prepared ramekin, stir in any mix-ins and air fry at 300 °F for 12-18 minutes until set and the center bounces back lightly when pressed (mine typically take 16 minutes).
For best texture, allow the baked oats to sit for 5 minutes to set.
Enjoy!
Notes
Cook Time: I give a large range for the cook time as it varies depending on how wide your ramekin is and thus how thick or thin the oat layer is as well as the model of air fryer that you use. The oats should appear set and bounce back lightly when pressed (like if you were baking muffins). If the top is browning too quickly, you can loosely cover it with aluminum foil.MakeAhead: Once mixed, the batter must be air fried immediately. If you would like to prepare these ahead, cook them fully and then reheat when ready.Leftovers: Leftover baked oats can be made ahead and stored in the refrigerator for up to 3 days. When ready to enjoy, simply reheat in the microwave or in the air fryer for about 5-8 minutes at 300 F.Protein Powder: I have tested this recipe with pea protein isolate and brown rice protein. I suspect that it would work fine with any protein powder of choice, but these are the only ones I have used.Omit the Protein: If you would prefer to make these without protein powder, simply increase the rolled oats to ½ cup.*Nutrition calculated based on the vanilla base recipe.
