My mom has made a variation of these brownies as long as I can remember. She doesn't know where she got the recipe from. I substituted whole wheat flour and honestly no one can tell it isn't made with white flour! You can substitute plain applesauce for part of the oil, but I like to use 1 c oil (as my mom does) with no applesauce - faster to measure, and it is a dessert after all! I hope you enjoy!
