Instructions

Add the milk and 1/2 teaspoon pure vanilla extract to a high-speed blender first.
Add the frozen banana, rolled oats, chia seeds, and pinch of fine sea salt.
Add the ice cubes.
Blend on low for 10 seconds, then increase to high and blend for 35–50 seconds, until completely smooth.
Check consistency. If too thick, blend in 1–2 tablespoons additional milk; if too thin, add a few extra ice cubes or frozen banana pieces and blend again.
Pour into a 16-ounce glass and serve immediately.

Tips

Use frozen banana to give the smoothie a creamy texture and natural sweetness without added sugar. Substitute almond or oat milk to make it dairy-free.
