Preheat the oven to 325°F. Line an 8x8-inch baking dish with parchment paper.
Brew a cup of coffee. You will only need 3 tablespoons in this recipe. (Enjoy the rest!)
In a medium saucepan, combine the sugar, butter, and coffee. Cook over medium heat until boiling.
Remove from heat and stir in chopped chocolate until melted and smooth. (Do not be worried if the chocolate looks like it's seized, it will relax when the egg is added.)
Mix in the eggs and vanilla.
Add the flour, baking soda, and salt. Mix until just combined. (Don't overmix)
Pour the batter into the lined pan and sprinkle with chocolate (optional).
Bake 20-25 minutes. Start checking at 18 minutes if you want OOEY GOOEY brownies!
