Combine all ingredients, except ice in a large blender and blend until smooth and creamy making sure the sugar has dissolved and is well incorporated. If desired, add a splash more of milk.

Add ice and blend until smooth. Serve immediately and garnish with orange slices.

If you wanna kick it up a little, add 1 to 2 ounces of Rum, Vodka, Gran Marnier, Malibu or alcohol of choice.
