Instructions

Add the milk to a high-speed blender.
Add the frozen banana, ground flaxseed, peanut butter, honey or maple syrup, vanilla extract, and fine sea salt.
Add the ice cubes last.
Blend on low for 10 seconds, then increase to high and blend for 35–50 seconds until completely smooth.
Check the consistency and blend in 1–2 tablespoons of additional milk if too thick, or add a few extra ice cubes or frozen banana pieces if too thin.
Pour into a 16-ounce glass and serve immediately.

Tips

Use ripe frozen banana for natural sweetness and creaminess. For a vegan option, use maple syrup instead of honey and a plant-based milk.
