Add banana, frozen strawberries, frozen peaches, and milk to a blender.
Toss in the yogurt if you’re feeling creamy. Sweeten with honey or maple syrup if your fruit isn’t sweet enough.
Blend until smooth. Pause to scrape the sides if needed.
Taste and adjust. Too thick? Add a splash more milk. Not sweet enough? You know what to do.
Pour into two glasses and enjoy right away.
