1 cup butter, melted
1 1/2 cups brown sugar
1 1/2 cups white sugar
1 tbs vanilla extract
1 1/2 cups all purpose flour
1 cup unsweetened cocoa powder
1 tsp salt
1 + cup(s) semisweet chocolate chips
Preheat oven to 350 degrees. Lightly grease 11 x 13 baking dish.
In a large bowl, combine the melted butter, sugar and vanilla. Add in the eggs, one at a time, and mix well.
In another bowl, mix together the flour, salt, cocoa powder and the chocolate chips. (Mixing the chips in at this stage will keep them from falling to the bottom of the pan during baking.) Gradually combine the flour mixture in with the sugar mixture.
Batter will be thick. Spread into baking dish.
Bake for 30-35 minutes, or until sides show signs of pulling away from pan.
