Prep your zucchini: If you haven’t already, slice zucchini into coins, peel if you want a paler smoothie, and freeze on a tray until firm. Transfer to a freezer bag for easy use.
Build your base: Add almond milk (start with 3/4 cup), frozen zucchini, protein powder, vanilla extract, cinnamon, sweetener, and a pinch of salt to your blender.
Add fats for body: Spoon in nut butter or drizzle in MCT oil.
Add heavy cream or coconut cream if you want a thicker, milkshake-like texture.
Blend until smooth: Start low, then increase speed for 30–45 seconds. If it’s too thick to blend, add a splash more milk. If too thin, add more frozen zucchini or a few ice cubes.
Taste and adjust: Add a bit more vanilla or sweetener if needed.
A pinch more salt can brighten flavors.
Serve immediately: Pour into a chilled glass. Optional toppings: a sprinkle of cinnamon, shaved coconut, or a few cacao nibs.
