Rinse the strawberries under cold water, remove the stems, and slice them in half so they blend smoothly.
Add the strawberries, frozen banana chunks, milk, and yogurt into a high-speed blender.
Blend on high for 60 to 120 seconds until the mixture is smooth and creamy with no chunks left.
Pause and taste the smoothie, then adjust by adding more milk if it feels too thick or a natural sweetener if you want it a little sweeter.
Pour into glasses or mason jars and serve right away, or cover and refrigerate for up to 24 hours.
