In a blender combine milk, vanilla, and frozen orange juice concentrate. Blend on high for a few seconds to combine everything together. (1 cup whole milk, 2 teaspoon vanilla extract, 16 oz frozen orange juice concentrate)
Add sugar and ice and blend on high for 30 seconds or if using a Breville Super Q just hit the smoothie option! (¼ cup sugar, 1 ½ cups ice)
