Preheat oven to 350° and line a 13x9 pan with foil. Grease foil and set aside.
Stir flour, salt, and cocoa together in a small bowl.
In a small sauce pan, melt chopped chocolate and butter over medium, stirring constantly, heat until fully melted and combined. Add in coffee.
Stir in the sugars and mix until completely combined.
Pour into a large bowl and add 3 eggs and whisk until combined. Add remaining 2 and whisk until just incorporated.
Add in vanilla and stir to just mixed. Don't overtax or that will result in cakey brownies.
Gently mix in the flour mixture, using a spatula, and fold until the flour is completely mixed in.
Pour mixture into prepared pan and smooth top.
Bake for 30 minutes or until a toothpick inserted in the center comes out with only a few moist crumbs.
Let cool completely before cutting. Lift them out of the pan using the foil and cut into squares.
