This frosting looks amaziing. Does this frosting need to be refrigerated or would it be possible to just keep at room temperature in a container? Also, I would love to know if this frosting could this successfully be used as a filling for whoopie pies? Would it stay intact or get really soft (ie., if it does require chilling, how long can it sit out at room temp) If anyone could advise on this, it would be great. Thanks :) It's stable at room temperature, but I wouldn't keep it on your counter very long - it'll harden up eventually. Not sure how long it can sit out before it hardens - my cakes and cupcakes have never sat around that long before disappearing! It would do fine as a filling for whoopie pies, I'd imagine - PJH
