Peel the banana and place the banana, yoghurt, honey and oats in a blender. Blend well. Toast the desiccated coconut in a dry pan until the edges start to colour.
Pour the yoghurt mixture into a tall glass and finish with the toasted coconut.
Tip: For an extra-cold shake, slice 3⁄4 of the banana and place the slices in the freezer overnight. Then proceed as described above.
