You can adjust this smoothie depending on how thick / milkshake‑y you want it. Use all frozen bananas and less milk for something thick enough to eat with a spoon — or swap half the banana for fresh and add extra milk if you like it drinkable through a straw. This also scales perfectly: the base formula is very forgiving and you can easily increase for meal prep or split into baby prep bowls to chill a few hours in the fridge (it stays surprisingly thick because dates and banana bind it).
