We use coffe mate creamer and put it in the cup before the coffee comes out, that way you know how much coffee for the cup. As for the frother, you don’t have to use it but if you do, just make sure you have less coffee and creamer in your cup before using it. We use regular mike or chocolate milk. When it spins, the milk does foam up which is the frothing part. I guess you could put whatever you wanted to in it and try it. I don’t see why you couldn’t just put the coffee creamer in it and try that.
