It's exactly what it sounds like. A root beer float, except the root beer is replaced with coffee. In my opinion, this makes the dessert about a million times better. I even have the cute little ice cream glasses to go with it (thanks Ashley).
All you need is french vanilla ice cream and some iced coffee. I made my own strong batch of coffee and shoved it in the fridge for a day. Then I stopped out some ice cream and poured the coffee until I had the desire ratio of deliciousness. It was like a vanilla latte. But better. I'm thinking of making some chocolate syrup and pouring some of that on top. Or caramel....mmmm, yum.
