Measure out the first five ingredients, and place them in the blender.
Measure out your ice. I use a general rule of thumb, which is using enough ice to fill the cup I will be using. (I like my shakes thick enough to eat like a milkshake, but if you wanted a thinner consistency, use about 1/2 the amount of ice!)
Next, place a few of your malted milk balls in a ziplock bag, and crush them using a rolling pin, a meat pounder, or even the bottom of a glass!
(This step is certainly optional~ because the malted milk balls are an optional garnish! )
Add water to blender just before blending, and blend until shake has reached desired consistency. Pour into serving glass.
Garnish with with light whipped cream, and a few crushed malted milk balls if desired!
