Place all ingredients in a blender.
Place the lid on the blender and place a towel over the top of the blender (this will prevent a possible "dust cloud")
Blend the ingredients until thoroughly combined and the powdered milk granules are the same consistency as the rest of your ingredients (about 1 minute, depending on how powerful your blender is)
To serve, add ⅓ cup mix to a mug. Fill with 7 oz boiling water.
Stir to combine and enjoy!
