I'm wondering how long the buttercream can go before it needs to be refrigerated. Is it stable at room temp? and for how long? Great post! That depends on the environment in your kitchen or pantry. If it is relatively cool (62 - 64 degrees) you may keep it at room temp for up to 48 hours. You will always have to remix buttercream no matter how long it sits to "lift" it up. Apply a little heat (double boiler or very quick microwave) and use your paddle on your mixer or use a hand whisk. If the temps are like summer (75 degrees or more), buttercream should really be stored in the frig passed 6 hours at room temperature. Elisabeth
