Feel free to customize your smoothie by swapping ingredients such as using almond or oat milk for a dairy-free option. Adjust sweetness with natural sweeteners like honey, maple syrup, or stevia instead of sugar. For added nutrition, consider adding spinach, protein powder, or chia seeds. If you have leftovers, store them in the fridge for up to 24 hours, although the smoothie is best enjoyed fresh. Adjust ice or milk amounts to achieve your preferred texture, whether thicker or more liquid.
