When I microwave a cup of coffee and add cream and mix it, there's there's some white stuff, looks like foam on the top. It looks like the cream isn't completly melting, but i've heated it up long enough to be very hot. still does it. Anyone know why?

I microwave a lot of coffee. I have never had a problem with the cream not mixing properly.
