Combine all the ingredients except for the nondairy milk in a food processor.
Process, adding nondairy milk one tablespoon at a time until it is creamy and smooth. It may take a while to get rid of all the lumps (up to 2 or 3 minutes of processing time).
Pipe or spread onto your cake/bread/cookie and enjoy. It is best used immediately after making as it will become much more firm and difficult to spread in the fridge.
