I found this recipe on another site and was happy to see it already posted here. I used Kahlua in place of the instant coffee dissolved in water and mixed extra marshmallows into the batter. I made 4 batches and baked the entire mixture in a 9" x13" pan until the sides pulled away from the pan and a toothpick pulled out cleanly. This yielded some seriously yummy brownies!
