Step 9: Lightly press the mixture into the pan.

In another bowl, add the Powdered Sugar and the melted butter. Whisk together until combined. (The mixture will be dry.) One teaspoon at a time, add the Instant Coffee liquid to the bowl and mix. Keep adding Instant Coffee liquid until the icing is the correct consistency to drizzle over the pan of treats.

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.
