In a blender or Vita-Mix, combine the ripe bananas, slices of fresh pineapple, grated coconut (reserving 1 tablespoon for garnish), apple juice, and ice cubes.
Blend on high speed until all ingredients are thoroughly combined and the mixture is thick and creamy.
Taste the smoothie and adjust sweetness or thickness by adding more fruit or juice as desired.
Once smooth, pour the Tropical Pineapple Coconut Cooler into mugs or glasses.
Garnish each serving with a sprinkle of the reserved grated coconut.
Serve immediately and enjoy the refreshing and tropical flavors of this delightful smoothie.
