Add frozen banana slices, pineapple (optional), lesser amount of coconut milk (3/4 cup or 180 ml as original recipe is written // adjust if altering batch size), matcha powder, and spinach to a blender and blend on high until creamy and smooth.
Divide between two serving bowls (amount as original recipe is written // adjust if altering batch size) and top with desired toppings (optional). I went with fresh raspberries, chia seeds, and coconut flake. Bananas would make a delicious garnish as well.
*Thin with water instead of coconut milk to save on calories, if desired.
*Nutrition information is a rough estimate.
