Assembly Instructions

Step 7: Spoon the mixture into a 9×13″ pan. We line our pan with a piece of parchment paper to make removing the treats from the pan easier.
Step 8: Lightly press the mixture into the pan.  You don’t want to press the mixture down too compactly, just smooth the top with a spatula or butter your fingers and pat down the top.

Step 9: Sprinkle 1 cup of Mini Marshmallows on the top of the treats.
Step 10: Place the pan under the broiler for 1-2 minutes or until the Marshmallows are toasted. Watch closely so the marshmallows don’t burn.

Serving/Storage Instructions

Rice Krispie 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.
