Prepare the matcha: Sift the matcha powder into a small bowl to remove any clumps. Add 2 tablespoons of hot (not boiling) water and whisk vigorously in a zigzag motion until frothy and fully dissolved. This traditional preparation step ensures your matcha blends smoothly without bitter lumps.
Cut and prepare the pineapple: Remove the crown, skin, and core from your pineapple, then cut the flesh into 1-inch chunks. If using frozen pineapple, measure out 2 cups and allow to thaw slightly for 5 minutes for better blending.
Combine all ingredients in blender: Add the prepared matcha, pineapple chunks, coconut milk, sweetener (if using), and ice to your blender. For a thicker consistency, use less liquid or add more ice.
Blend until smooth: Start at low speed and gradually increase to high, blending for 45-60 seconds until the mixture is completely smooth and vibrant green. Stop to scrape down sides if necessary.
Taste and adjust: Sample your creation and adjust sweetness or thickness as desired. If too thick, add a splash more coconut milk; if too thin, add more ice or frozen pineapple.
Serve immediately: Pour into chilled glasses for a drink or into bowls if creating a smoothie bowl. Top with fresh pineapple chunks, mint leaves, and toasted coconut if desired. For best flavor and color, enjoy right away while the matcha is fresh.
