Notes
- Use mini marshmallows to speed up cooking time if you're crunched for time. They will melt faster, yield quicker cooking time, and less time for guests to get these treats onto your table. Keep the heat on medium-low. You will have hard rice krispies squares if the heat is too high.
- Let marshmallow mixture sit for 20 mins. Minimum before adding Rice Krispies cereal. This will help prevent the Rice Krispies cereal from becoming soggy. You want a nice crisp crunch to your final marshmallow square treats.
- Place finished treats into an airtight container. It will help your rice krispies treats from becoming soggy. They will absorb moisture, and to help eliminate this, an airtight container.
- Store in an airtight container for up to one week.
- For longer storage, you can freeze your marshmallow squares. To do this, ask yourself if you will take out one square at a time or take them all out at the same time. If you take them out one by one individually, wrap them with freezer paper, tape down seams, and wrap them in tin foil (to avoid odors and off taste), then place them into an air-tight freezer baggie or container. Next, pop them in the freezer. If taking them all at once, there is no need to individually wrap them.
