Step 1: Melt the butter in a large saucepan on medium-low heat.

Step 8: Spoon the mixture into a 9×13″ pan that has been lightly greased with butter.
Step 9: 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. Let the Rice Krispie Treats cool and then cut them into squares.

Serving/Storage Instructions

Step 10: 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.
