Measure and gather all base ingredients: milk, Greek yogurt, frozen mixed berries, banana, honey, vanilla extract, and ice. If using a frozen banana, let it sit at room temperature for 5 minutes so it's slightly easier to blend.

Layer in blender

Add milk and Greek yogurt to the blender first (this helps liquid flow), then add the frozen berries and banana chunks. Sprinkle in honey and vanilla extract. Top with ice cubes.

Blend to smooth

Secure the lid and blend on medium-high for 45–75 seconds, stopping to scrape down the sides once if needed. Blend until smooth and no large fruit or ice pieces remain. If mixture is too thick, add up to 0.25 cup more milk and pulse to incorporate; if too thin, add a few more ice cubes or 2–4 tablespoons more frozen fruit.

Optional Boosters & Add-ins

If using protein powder, ground flaxseed, or spinach, add them to the blender on top of the other ingredients before blending. Blend an additional 10–15 seconds until fully incorporated and the spinach is uniformly mixed without visible leaves.

Garnish / Finish

Pour the smoothie into a 32 oz (large) cup or two smaller glasses. Top with the extra berries, drizzle with the teaspoon of honey, and add mint leaves if desired. Serve immediately with a wide straw.
