Cut the peel off the Seedless Orange (3) by cutting off the top and bottom to the flesh. Then run your knife down the sides along the flesh removing the sides in large strips.
Segment the orange by running your knife along the membrane on both sides of each segment which will loosen it from the orange.
Place oranges, Ice (2 cup), Vanilla Greek Yogurt (2/3 cup), Orange Juice (1/3 cup), Non-Fat Dry Milk Powder (2 tablespoon) and Vanilla Extract (1 teaspoon) in a blender and blend until smooth and creamy.
Pour into desired glasses and serve immediately.
