powder milk is not soluble in water thats why it forms a suspension (suspension - when small particles that cannot be dissolved into a liquid, floats around to form a cloudy appearance. 

Butter on the other hand do not MIX with water as when its liquefied, the non-polar hydrophobic bonds cannot coordinate with the polar water molecules and hence tend to phase separate. Therefore, butter and other oil will form a bi-layer when mixed together.
