I read somewhere that sugar "preserves" a buttercream frosting i.e., the cake can be left "out" and not refrigerated. True? Thanks for your help. Cassie

i have also read this on other cake sites... i do believe it is true.... if you use milk or whipping cream in your icing, the sugar preserves that along with using butter in your recipe. i know someone will give you better details than i can.

I have heard it before as well - I have to email my Food Safety teach a few questions - that is one of them. How long can I leave out a cake that has been frosted and "fondanted". I will let you know when I hear back from her.

If you're referring to the tiny amounts of milk or cream used in American b/c recipes, you're correct.

I have provided information that sugar is hygroscopic (or moisture absorbing) so it can be used to alter the "water activity" in American b/c made with cream cheese:

Not being a food scientist, I wouldn't attempt to "doctor" a perishable cake frosting or filling recipe with sugar to make it shelf stable.

For example, adding a little extra powdered sugar to a basic whipped cream frosting IS NOT going to make it shelf stable.

Speaking in generalities, is probably not a good idea when it involves food safety issues. For example, the stable cream cheese frosting recipe I posted may be vastly different from yours; so the results of not refrigerating yours could be disastrous.

If you have questions about a specific recipe, please post it, and I'm sure you'll get responses. icon_smile.gif

Love the quick responses. I'm using a buttercream recipe, a combination of shortening and butter, I found the recipe "Crusting Buttercream Icing (Viva Method) on this site. The only change I've made to it is to add milk (at most 1/3rd cup) rather than water. I'm not using cream cheese, or whipping cream. It sounds as though you agree that it is safe to leave out for a couple of days?? Once more, thank you for your help.

Your recipe should be fine. icon_smile.gif

However, using milk or another liquid with fat can affect the crusting (the more fat, the less crusting).

Help? It's more than I asked. Now I know that I can have the cake on the counter for a day and feel secure about it, AND that I should use water instead of milk for a better crusting effect. Thank you so much, Jan, there is something to learn everyday and this is the site from which to learn. Cassie

Thank you for pointing me in a useful direction i.e., searching for refrigeration... I used to read info on 911, but gave it up when the cost was instituted. I feel more comfortable going ahead with my baking now. Cassie




No problem! I would love to know if you find some more concrete info on this topic. I am so sad I can't look at the info on 911 anymore. I wish I would have copied those posts when I had the chance! -Anne
