Combine the water, honey and vanilla bean pod in a small saucepan over low heat. Simmer for 7 to 9 minutes, stirring occasionally, to allow the vanilla to infuse into the honey. Remove the vanilla pod and allow the mixture to cool completely, about 10 to 15 minutes.
In a blender, combine some of the vanilla honey with the yogurt, mint and 1/2 tray of frozen coconut water cubes, or more for desired consistency. Puree until smooth, then pour into glasses and garnish with a sprig of fresh mint. Serve immediately.
