Add the orange juice concentrate, milk, sugar, vanilla extract, and ice to a blender. If you’re using pudding mix, add that as well.
Blend
Blend on high speed for about 1 minute, or until smooth, creamy, and frothy. Add a splash of extra milk, if needed, to thin the drink until it reaches your desired consistency. If it's too thin, you can add extra ice cubes.
Serve
Pour into glasses and enjoy immediately!
Notes
This recipe yields enough for two large glasses or 4 smaller glasses.If you have leftover instant vanilla pudding mix, use it to make this easy fruit salad!
