The recipe (for a single serving) reads at the following:

1 big scoop of ice cream
4 oz of pineapple juice
2 cups of frozen pineapple
Add all ingredients to a blender until it’s a thick drink.
Add your swirl and then you’re done.
Just a note: The original Dole Whip is dairy-free, so you’ll want to use dairy-free ice cream if you want to make the real option. You can check out Dole’s official recipe or see Dole’s official soft serve mix for more information.
