This is how I make my Piña Coladas. Hope you like it.
1 Can of Cream of Coconut (I use the Goya Brand as its cheaper than the Coco Lopez one

)
2 Cups of Pineapple Juice
Optional: 2oz of Rum (you don't want it to take away the flavor of the coconut and pineapple) I personally don't drink alcohol any longer but even when I did Piña Colada was something that I liked with little or no alcohol I think it tastes better that way.
And enough ice to make it icy.
Enjoy! Decorate your glasses if you like with pineapple chuncks and strawberries.
P.S. Don't but those Piña Colada Mixer stuff their nasty IMO!
