My secret is orange juice! You wouldn't think that should be in a pineapple and coconut drink, but the tangy taste brings out the flavors of all the ingredients. To make this a mocktail, leave out the rum and swap for some extract if you'd like. Simple as that.
Fill blender half full of ice. Add orange juice, pineapple juice, cream of coconut, heavy cream, and rum (or rum extract). Blend until very smooth.
Garnish with a pineapple slice and toasted coconut. Drink immediately.
How to make a frozen pina colada:
I usually mix up a batch, or double batch of this drink in a few pitchers and keep it ready to blend with ice. In the recipe I have you mixing it all in the blender with the ice, and that is great too, if you're sure to serve 4 people all at once. My drink mix is meant to be blended, but you can definitely stir it into a glass of ice and serve it on the rocks as well. It's pretty concentrated so whether you're blending or serving on the rocks, use plenty of ice.
