Prepare the Fruit: Wash the strawberries well and remove the stems. Peel the kiwis and slice them into chunks, then peel the banana and break it into smaller pieces for easier blending.
Add Liquid to the Blender: Pour the milk into the blender first. Starting with liquid helps everything blend smoothly and keeps fruit from sticking underneath the blades.
Add Strawberries, Kiwi, and Banana: Place all the fruit into the blender evenly. The banana helps create a creamy base, while strawberries and kiwi bring the bright flavor.
Add Yogurt and Sweetener: If using yogurt, spoon it in now for a richer texture. Add honey or maple syrup if you want the smoothie sweeter, especially if the kiwi is very tart.
Add Ice Cubes: Drop in the ice cubes for a chilled, frosty finish. Frozen strawberries may reduce how much ice you need.
Blend Until Smooth: Blend on high speed for 45 seconds to 1 minute until the mixture looks silky and smooth. Stop once to scrape the sides if needed.
Check Thickness: If it feels too thick, add a splash more milk and blend briefly again. If too thin, add a few extra frozen strawberries.
Pour and Serve Right Away: Pour into chilled glasses and serve immediately while cold and fresh. Smoothies taste best just after blending, when the texture is smoothest.
