Start by cutting your ripe watermelon into cubes, ensuring you remove any seeds. Peel and slice 1-2 bananas and place them in the freezer for about 2 hours. Gather your frozen strawberries, vegan yogurt, lime, and optional maple syrup while waiting.

In a high-speed blender, combine the prepared watermelon cubes, 1-2 frozen bananas, a generous cup of frozen strawberries, and about ½ cup of vegan yogurt. Squeeze in the juice of one lime and add the zest for extra brightness. Drizzle in some maple syrup if desired before securing the lid.

Blend the mixture on high speed for about 30-45 seconds, until everything is fully combined and the consistency is silky smooth. Use a tamper to push down any frozen ingredients if necessary.

Check the smoothie’s thickness; if it’s too thick, add a small splash of cold water, about 1-2 tablespoons at a time. Blend again until you reach the perfect creamy consistency.

Pour the creamy watermelon smoothie into tall glasses or a hollowed-out mini watermelon. Garnish with fresh mint leaves or a lime wedge if desired. Serve immediately for the best flavor!
