a new favorite cookie

A new cookie in the house...a
mocha-brownie-ish-melt-in-your-mouth 
sort of cookie.
It received rave reviews here,
and my taste testers are a bit on
the choosy side.

My notes/changes::
  • I had no bittersweet chocolate, so used semi sweet chips.
  • I had no espresso, so used 1 tbsp instant coffee.
  • I had to up the temperature a little bit.
  • Definitely had to chill the dough first. 
Found the recipe here.
