This easy coffee smoothie recipe combines all the things that are good about mornings in a healthy package. First, you’ll make a combination of milk and oats to soften them into an oatmeal-like consistency. The softened oats and milk get blended up with banana, cold-brewed coffee, and maple syrup for a delicious twist on the standard breakfast smoothie. Cold-brewed coffee is usually in the refrigerated drinks section of grocery stores. But, if you can’t find it, you could also substitute chilled home-brewed coffee or espresso.
