This isn't really what you asked for but she has heaps of tasty recipes on here - including brownies I think. They aren't all necessarily "healthy" - moderation though!!

I don't really use a recipe as such. I just take a brownie mix, substitute plain yogurt for half the oil and all but one egg (2 Tablespoons yogurt per egg) and reduce the calories and fat that way. Bake as on the box. Nice plus..the brownies are moister and taste fudgier than if made according to the box directions!
