Assembly Instructions

Step 6: Spoon the mixture into a 9×13″ pan.  (We line the pan with a piece of parchment paper to make it easier to remove the treats from the pan when they are cooled.)
Step 7: We sprinkled the top with a handful of the Lucky Treat marshmallows and then lightly pressed the mixture down in the pan.
Steps 8-9: Let the treats cool in the pan and then cut them into individual bars.

Serving/Storage Instructions

Marshmallow Treats will last 2-3 days at room temperature in an air-tight container before they start to get stale. You can extend that timeline a few days if you store them in the refrigerator and then take them out about 30 minutes before you eat them. They freeze up great though and that is what we do if we want to make these ahead of time for a party or a family gathering.  They defrost very quickly and taste great once they are defrosted. You can keep them in the freezer for up to a couple of months.
