1. Using whole wheat flour will create an extra chewy brownie which I like. But you can substitute the same amount of all-purpose flour or white whole wheat flour in this recipe.
2. I used mini semi-sweet chocolate chip in the flour mixture, but you can substitute regular size semi-sweet chips, milk chocolate chip for a sweeter taste or bittersweet chips for the opposite effect.
3. Store brownies in an airtight container on the counter for up to 5 days.
