In a high-speed blender, start by pouring in 1 cup of whole milk or your preferred alternative milk. Next, add 1 cup of plain Greek yogurt, then carefully slice and add 1 ripe banana followed by 1 cup of sliced frozen peaches. Finish with a drizzle of maple syrup or honey.

Secure the blender lid tightly and blend the mixture on high for 30 to 60 seconds until creamy and frothy. Check for consistency and ensure no fruit chunks remain.

If needed, pause and use a spatula to scrape down the sides to ensure even mixing. Blend for an additional 10 to 20 seconds.

Pour the smoothie into tall glasses and optionally garnish with a slice of peach or a sprinkle of granola. Serve immediately for the best flavor.
