Do you need ice cream to make a chocolate banana smoothie?

There are many recipes for making banana milkshakes, but they are easy to make without using a recipe. Measure and dip 1 cup of vanilla ice cream into a blender, peel and slice 1 large or 2 small (more if desired) banana(s), and add about 1/2 cup milk. Place the lid on the blender and blend until it is well-mixed. You can adjust any or all ingredients to your taste as well as to the thickness (or thinness) of the shake.
