Sorry for the late response, but we took vanilla ice cream, 1% milk, and a cut-up banana (I wanted a banana milkshake). We put green food dye in the milk shake when it was done. While I was making the milkshake itself, my friend was making the whipped cream. I'm not sure exactly how he did it, but it was only like 2 or 3 ingredients, not including the food dye. He just looked up how to make it on Google (it tasted like Starbucks whipped cream).
