Set oven to 350F
Cream the butter, espresso powder, cardamom and sugars together until fluffy. About 2 to 3 minutes.
Beat the eggs in, one at a time. Then the vanilla.
Whisk the flour, soda and salt together and then add to the eggs and butter, mixing just until combined.
Mix in the chocolate chips.
Spread the batter (it will be thick) into a 9x13 glass baking dish, lined with parchment (or greased).
Bake for 30-35 minutes. Don't over bake. They'll be wrinkled a bit around the edges, and a little bit of squooshyness inside is a good thing.
Cool before cutting. (or don't)
