The key to preventing soggy Rice Krispie Treats is moisture control. Here are some tips: Don't overcook the marshmallows. Overcooked marshmallows release more moisture, leading to a softer treat. Aim for a smooth consistency, not a bubbly boil. Don't overcrowd the pan. This prevents the cereal from drying out evenly and can create steam pockets, leading to sogginess. Let the treats cool completely before storing them. This allows excess moisture to evaporate. Store them in an airtight container at room temperature. Avoid storing them in the refrigerator, as the cold temperatures can attract moisture and make them soggy.
