My father-in-law taught me a wonderful trick when he learned that I have a weakness for root beer floats. He told me to try adding a little bit of milk to root beer, and see what I think about it.
While it is not as rich and creamy as adding ice cream, the overall taste is remarkably similar, and for far fewer calories!
So if you like root beer floats, give this low-fat version a try. I bet you’ll like it! You can experiment with how much milk you add to your glass. I tend to do roughly 4 parts root beer, 1 part milk.
