Sympathy for the Demon - S5-E7
Corrected entry: When Cole drinks the power stripping potion, his powers go to Barbas, but in season 4's "Black as Cole," when Cole is hit with the power stripping potion, his powers just disappear, no one gets them.

Correction: We are talking about completely different powers that act in completely different ways - it's not the same as stripping his demon half from his human half.
