Combine all ingredients in your blender and blend for 2 minutes.

Pro Tips
Most orange juice concentrates are 12 oz, so I just make 2 batches (because most blenders are not big enough to blend it all at one time) and then save the leftovers in the blender in the fridge.
When we want the leftovers I just stick the whole thing back on the blender for a minute or so to froth it back up.
If you are looking for a healthier option you can substitute Splenda for sugar or use fresh squeezed orange juice in place of orange juice concentrate.
