Okay I tried this. What type of consistency should it have? I was trying to use it to frost cupcakes and was going to put it into a pastry bag and pipe the traditional swirl on top. I made this and came out with a runny consistency. I added more powdered sugar to try and get it to thicken up but no use. then i tried to add some cream of tartar to see if maybe that would help and it did but definitely not enough to get it to take a shape. PLEASE LET ME KNOW WHAT I DID WRONG AS I AM SEARCHING FOR A COFFEE FROSTING!!
