Fudgy brownies have a higher fat-to-flour ratio. They have more fat, usually butter, and a small amount of flour. The leavening agent in fudgy brownies is the whipped eggs. The key is to whip the eggs until they are light in color and thickened inconsistency.

This now my go to recipe. I've made it twice in fact because the family loves it! Fudgy and not so sweet. It keeps well and tastes just as good a week after - assuming it lasts as long. You don't even need a mixer and no tricky steps. That's the way good food normally is...straightforward and uncomplicated.
