Add in your eggs then add in the vanilla. If you are using chocolate chips instead of chocolate chunks, you can mix in the 2/3 of a cup after the eggs are thoroughly combined into the mix.
Once all that is mixed very, very well, add in your flour and barely stir it in. Just barely. I read somewhere that stirring the flour mixture creates gluten, which in turn creates the cakey texture I don't like for brownies. So in theory, the less you stir, the less gluten and then chewy brownies here we come!
I used chocolate chunks, which I placed on top of the batter. They are so heavy that they sink right into it. Bake at 350 degrees for 30-40 minutes, until the brownies pull away from the edges slightly.This is why I use the chunks, they sink in right to the top level of the brownies. Cool the brownies.
This brownie recipe is easy to adapt to your liking, you can use any type of chocolate chips that you want, add walnuts to the batter, marshmallows, it's really is the best base brownie recipe out there!
