In your blender, combine ½ cup of the milk and malted milk powder. Pulse your blender 3-5 times, just until the powder is mostly mixed into the milk.
Add the ice cream and chocolate sauce and blend until combined. Use a spoon to stir the shake, and add the remaining ¼ cup of milk if it's too thick.
Serve topped with optional whipped cream and sprinkles, and enjoy!
