This protein-packed, naturally sweet smoothie is the ultimate after-school snack to keep kids energized and satisfied until dinner. It features a velvety texture and a classic flavor profile that tastes like a milkshake but is loaded with healthy nutrients.
For a nut-free version, substitute peanut butter with sunflower seed butter. To make this ahead of time, blend everything and pour into popsicle molds to freeze for a healthy frozen treat. If the smoothie is too thick, add an extra splash of milk 1 tablespoon at a time until the desired consistency is reached.
