- 1 cup frozen blueberries — the star of the show. Frozen works best because it chills and thickens the smoothie without watering it down.
- 1 piece ripe banana — adds natural sweetness and a creamy texture. If you're not a banana fan, half an avocado works surprisingly well too.
- 1/2 cup plain yogurt — Greek yogurt if you want extra protein and a thicker result. Dairy-free yogurt works just as well.
- 1/2 cup milk (or milk alternative) — oat milk, almond milk, or regular milk all work fine. Start with less; you can always add more.
- 1 teaspoon honey or maple syrup (optional) — taste first, since the banana and blueberries often bring enough sweetness on their own.
