Prep the fruit: Peel and cube the papaya, and peel the banana. For a thicker smoothie, use frozen banana or partially frozen papaya.
Add to blender: Place papaya, banana, milk, and yogurt in a blender. Start with 3/4 cup milk and add more if needed.
Flavor boosters: Add honey or maple syrup if you prefer it sweeter, a squeeze of lime or lemon for brightness, and ginger if using.
Blend until smooth: Start on low, then blend on high for 30–45 seconds.
If it’s too thick, add a splash more milk. If too thin, add a few ice cubes or more frozen fruit.
Taste and adjust: Check sweetness and acidity. Add an extra drizzle of honey or a bit more citrus if needed.
Serve: Pour into a chilled glass.
Top with a mint leaf or a sprinkle of ginger if you like.
