Can I substitute condensed milk for evaporated milk in icing? My icing recipe for German chocolate cake pecan icing calls for evaporated milk, but I only have condensed milk. Can I use the condensed milk instead?

If so, do I need to make any adjustments to it?
Yes you can. 


If you have unsweetened condensed milk, that is another name for evaporated milk and they are interchangeable. 





If you have sweetened condensed milk, you can use one 14 oz can to replace one cup of evaporated milk and one cup of granulated sugar.
