DirectionsPreheat oven to 350F.
Melt butter, combine with sugars and cocoa.
Add eggs one at a time.
Mix flour, salt, and baking powder (reduce to 1 tsp of baking powder for denser brownies).
Add the wet ingredients to the dry, mixing well.
(Though if you're short on bowls, you can dump the flour etc right on top of the wet stuff and it will not make much difference if you mix it really well.
Once everything is mixed add in the chocolate chips.
Spread in a greased or nonstick 9 x 13 inch baking dish.
Bake until toothpick comes out clean, approximately 25 minutes.
