Add liquids first. Pour the milk into the blender. This helps the blades catch and blend smoothly.
Add the creamy elements. Spoon in the yogurt and add the banana pieces.
Top with frozen fruit. Add the frozen strawberries on top so they blend evenly.
Flavor it. Add the vanilla, a small pinch of salt, and sweetener if using.
Blend until smooth. Start on low, then increase to high for 30–45 seconds, or until completely creamy.
Adjust texture. If it’s too thick, add a splash more milk.
If too thin, add more frozen strawberries or a couple of ice cubes and blend again.
Taste and tweak. Add a little more sweetener or a squeeze of lemon for brightness if needed.
Serve immediately. Pour into a chilled glass and enjoy right away for the best texture.
