In a blender, add all ingredients and blend until smooth. Pour into a glass and enjoy!
If you prefer the iconic Dole Whip swirl, pour mixture into a shallow baking dish (like you would make brownies in) and freeze for an hour or longer. (You may need to reblend it a second time to get it to defrost a little bit.)
Then fit a piping bag with a star-tip and spoon in the frozen mixture. Then pipe the mixture into a bowl. To make a swirl shape, make a big circle and spiral in toward the center to fill in the circle, then continue to layer the swirls, filling in the centers as you go until you reach the top.
Notes
If you need to firm up the mixture, or if you desire some extra tropical flavor, add in 1 banana to the blender and combine.
