Yes, though the exact method will vary slightly based on the strength of your microwave. However, as a general guideline: Add the ingredients to a high-sided (this is important as the oats will puff up as they cook) microwave-safe bowl and microwave on high for between 2-3 minutes (based on the strength of your machine), stopping every 30 seconds to give it a good stir then leaving it to rest for 3 minutes. Adjust the amount of liquid as needed - you usually need slightly less than the stovetop version.
