Double barrell the scare card?

[Piece of Cake]

This probably is not a good example. Moreover, my bet was a weak one. If I do bet the turn, I do understand that a bet on this street is a bluff.

In general though, I cbet at a high rate, and when I cbet whiffed flops and get called, I typically double barrell at a high rate as well. Some considerations/reads come in to play of course, but I was wondering what your opinions on this habit are.
