Lightly grease a 10-12 oz microwave-safe ramekin or mug.
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 and stir in any mix-ins.
Microwave for 1 and ½ to 2 minutes, checking them early, until the center is set and bounces back slightly when pressed.*They may puff up as they cook but will sink back down as they cool.
For best texture, allow them to sit for 5 minutes to set.
Enjoy!
Notes
Cook Time: I give a large range for the cookinging time as it varies depending on your model of microwave and how wide your ramekin is and thus how thick or thin the oat layer is. The oats should appear set and bounce back lightly when pressed (like if you were making a sponge cake).MakeAhead: Once mixed, the batter must be microwaved immediately. Since it is such a quick recipe, I recommend not making them until you are planning to eat them.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 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. I recommend using the blended method in this case.*Nutrition calculated based on the vanilla base recipe.
