FAQ
No one likes a soggy cereal treat. So avoid adding too much butter and store cooled treats in an airtight container at room temperature. Do not refrigerate.
Avoid overcooking your marshmallow mixture. Cook on low and only cook butter and marshmallow mixture until the marshmallows have melted. Immediately remove it from the heat before adding the cereal.
Sprinkle a little more cereal into your mixture if your treats seem too sticky, but you must add it before cooling off.
