Slimmed-down Piña Colada

I got the idea for this cocktail from a blog I regularly read and enjoy, Carrots 'n' Cake. We've been mixing up cocktails for the boat when we go to visit my parents, but the last round of sugary Mai Tais killed out stomachs (but they were SO GOOD!). The recipe is great as she makes it, but I'm not sure just the coconut rum will cut it with everyone I may make them for!

Slimmed-down Piña Coladas

6 oz coconut water (such as Vita Coco or another brand)

3 oz pineapple juice

2 oz coconut flavored rum

1-2 oz white rum (if desired, to taste)

Add all ingredients to a shaker with ice, shake it up and you're done!
