I am making holiday cupcakes for an event tomorrow.  I ordered the supplies I needed in plenty of time but due to an issue with UPS do not have them.  I mostly make my own buttercream but to save time, since there are a lot of cupcakes to be done, I ordered a really good brand of pre-made buttercream.  Since that did not arrive I decided to try the Wilton Decorator Icing.  This was a mistake.  The texture was off from the beginning.  Using it with tips looks terrible.  There are no details showing up and it looks like a large ugly blob.  I have never had this kind of trouble with buttercream.  Anyone have any ideas on how to save this icing?  If not I will be headed to the store to get the supplies to make my own and I will be up late decorating.  Thanks!

Your frosting is too thin. I have used that recipe in my Wilton class for 8 years and never had a problem with it.

To rescue this problem, beat in some softened butter and then a small amount of sugar.  CAREFULLY add more sugar until you get a good peak consistency. 

If you have to start over: Use the Wilton recipe for snow-white buttercream. Works first time, every time.  Needs meringue powder which is widely distributed in crafts shops. 

If all else fails, make buttercream using 1 pound of butter to 2 pounds of powdered sugar adding enough corn syrup until you get a good spreading consistency.  

And remember to cancel that icing order if possible.

AThanks. I finally tossed it and made my own. This was not the mix but the pre-made container so it came right out of the tub that way. I have never had that problem with buttercream before and will just stick to making it myself or using this other brand. I don't know what was happening with this icing but it looked and felt wrong from the moment I opened the tub.

Seems like you have everything figured out.
