I am obsessed with brownies and most gluten free brownie recipes just don't do it for me (or else require a lot of effort or expensive ingredients). I adapted this recipe from the Dec. 2012 Bon Appetit magazine's recipe. They are very rich - which will actually keep me from eating the whole pan! Be warned - due to the diversity of gluten-free flours, I don't recommend making substitutions. I have tried every combination and this one really works for brownies. If you are dairy-free and have to use a margarine such as Earth Balance, be sure to reduce the salt to 1/4 teaspoon or omit it entirely.
