I know this has been asked tons of times, but I never thought about it until now i have made up a batch! It's Edna's recipe, basically butter, shortening, cream cheese, sugar and vanilla.

It's on cupcakes for lunch tomorrow, so it will be less than 24 hours, but wanted to make sure it will be ok, or should I put them in the fridge overnight? I didn't want it to try out my cupcakes too much!

Thanks for the last minute help!

yes I would! I always refrigerate my cream cheese frosting especially for a long period of time like that.

I've actually left them out before and they were perfectly fine.

I always put cream cheese icing in the fridge. Is it cold outside where you live? If so, put them in the car tonight. I've done that, too, and then I know I won't forget to bring them with me!

Fridge it!! Cuppies once iced won't dry out easily so overnight isn't a problem. I usually put mine in the containers I deliver them in and then stick them in the fridge.

Hi Sullymel13, I am a chef by profession. Sugar as salt are natural preservatives, you can leave your cream cheese icing outside without any refrigeration only if it has 70% or more of powder sugar. Other than that keep it cold. Here at Sprinkles we keep our icings outside because the sugar ratio is very high and if we store them in the fridge the sugar crystalizes and becomes very hard to stir them. Have a happy baking.

Thanks so much for all the help! I'll put them in the fridge tonight!

There was a similar thread about this on cc pretty recently and I believe that someone said that Edna's cream cheese frosting did NOT have to be refrigerated while most others do. I tried to find it but couldn't, maybe someone else will have better luck.

Good Luck!
