Pre-heat the oven to 350 degrees F. Line a 8x8 inch pan with two pieces of parchment paper, leaving a couple inches of overhang on all sides, in order to remove the brownies easily from the pan.

Whisk together the flour, salt and baking powder in a small bowl. In a large bowl, whisk together the cocoa and coffee until smooth. Whisk in the olive oil, melted chocolate, egg and vanilla. Whisk in the sugars. Using a rubber spatula or wooden spoon, fold in the flour mixture. Add in the chocolate chips and gently stir.

Spoon the mixture into the prepared pan, spreading batter into the corners and bake for 20 minutes or so, or until the brownies have set. You can use a wooden skewer to test the center of the brownies. The skewer should come out with dry crumbs when the brownies are done. Sprinkle the sea salt on the brownies when they are still warm. Once cooled, cut into squares. Optional garnish: powdered sugar and melted chocolate drizzle.
