Combine the banana, frozen mango, frozen pineapple, coconut milk, juice of your choice, and ice cubes in a blender. You can break the banana into smaller chunks for easier blending.
Blend the mixture on high speed until it reaches a creamy and smooth consistency. Don't forget to pause to scrape down the sides of the blender.
Taste the smoothie and adjust the flavor to your liking. Add coconut flakes into the blend for a stronger coconut taste. If you prefer a sweeter smoothie, consider adding a touch of honey. Pour the smoothie into glasses and garnish with coconut flakes.
