Buttercream frosting does not need to be refrigerated if used within two to three days. However, it keeps for up to two weeks if stored in the refrigerator in an airtight container, and it lasts up to three months if stored in the freezer. Keep Learning.
2 weeks out of the fridge, a month inside the fridge. You do not need to refrigerate a 1/2 Crisco, 1/2 butter icing that is made with a couple of tablespoons of milk. Store your icing at room temperature in a bowl with an airtight lid. Crisco-only buttercream made with water will last up to 6 weeks at room temperature. Buttercream containing butter and/or milk will be good at room temp for up to 3 weeks, although 2 weeks is my personal threshold.
