This brownies recipe is one of the best that I`ve ever made, the greatest thing about it is that you can play with it and add or omit whatever you like, and still get a great brownie. To my opinion, you can reduce the sugar, and use only one cup (that is, if you are using white chocolate, that adds a lot of sweetness). You can also add chocolate chips, pecans, a bit of alcohol (Irish cream, Frangelico…) or whatever you have at home.
If you wish that your brownies will have a clean look, and that applies especially to the fudgey ones, make sure to freeze the brownies after you bake them, and them cut them with a very sharp knife. Even if you are tight in time, never cut brownies while still hot, or you will get a crumbly mess.
