- Separate a Marshmallow Peep from the pack.
- Place on a microwave-proof plate (fireproof as well, if possible) and place in microwave.
- Set on low-medium for 20 seconds.
- Watch the transformation.
- Enjoy the results.
Note: Longer times or higher temperatures may result in a "carmelization" of the peep, which can be difficult to clean off the microwave interior. (No, I didn’t let them try it!)
