Notes

Cereal to marshmallow ratio: Start with ½ cup of Rice Krispies cereal at first, then add more if you want it to be thicker. I prefer my ratio of cereal to marshmallow to be more marshmallow-heavy, and it's also easier to eat with a spoon.
Mug size: You want your mug to be at least 8 ounces.
Microwave wattage: My microwave is 1500 watts, so you may need to adjust your time to be less or more depending on the wattage of your microwave.
