I am not sure what cookbook my mom got this recipe from, but we have been making them for at least 20 years. I lost my recipe and when I looked it up today, I was thrilled to see it here. For any chocolate/coffee lover these kahlua laced brownies are decadent. Tonight I am baking them for a party in which we are supposed to bring whatever we would request for our last meal! Served with vanilla ice cream; these are a dream.
