Roughly chop the dark chocolate bar. Roughly chop the butterscotch chips. Chop 6 strips of the cooked bacon into small pieces about the size of a chocolate chip. Finely mince the remaining 2 strips of bacon.
In a large bowl combine the butter, brown sugar, egg, and vanilla. Beat everything together. Add the flour, baking soda, baking powder, and salt to the butter mixture, and beat until fully combined.
Scoop the cookie dough into balls, approximately 2-3 tablespoons of dough for each. Roll the top of each ball into the remaining chopped chocolate, then place onto the prepared cookie sheets. Bake the cookies for 10-14 minutes.
Remove the tray of cookies from the oven, give the tray a couple taps onto the countertop to help settle the cookies. Sprinkle the tops with the minced bacon, and flake salt. Let cool until set then serve
