Preheat oven to 350°F and line a standard-size loaf pan with parchment paper or grease with non-stick spray.
In a large mixing bowl, combine all ingredients and mix well using a rubber spatula or whisk.
Fold in chocolate chips, then transfer the batter to the loaf pan.
Top with additional chocolate chips if desired, then bake for 45-50 minutes or until a toothpick inserted into the center comes out mostly clean.
Allow the brownies to cool for 30 minutes before slicing and enjoying!
