Place ingredients in the blender following the exact sequence above (i.e. crushed ice first in the bottom of the blender, and so forth). Blend everything well until obtaining a homogeneous, creamy mixture (You might experience a bit of difficulty in getting the shake to blend at the very beginning, but keep alternating crushing, pulsing, and liquidifying. If necessary, remove cup from blender and stir a bit with a spoon before blending mixture again). Serve the Chai Vanilla Milkshake immediately!!!
