Preheat the oven to 350º F (180 C). Line a 13×9 inch metal pan with foil and spray foil with cooking spray.Melt the butter, 8 ounces (1 1/3 cup) semi-sweet chocolate chips and the unsweetened chocolate in a medium bowl over simmering water. Allow to cool slightly. You may also do this in the microwave.Stir (do not beat) eggs, vanilla, and sugar together in a large mixing bowl. Stir the warm chocolate mixture into the egg mixture and cool to room temperature.Stir the flour, baking powder, salt and espresso powder together in another bowl then add to the cooled chocolate mixture. Stir in the Oreos and remaining chocolate chips.
Bake for 20 minutes, then rap the baking sheet against the oven shelf to force the air to escape from between the pan and the brownie dough.
Bake for about 10 minutes more, or until a toothpick comes out clean. Do not overbake! Allow to cool, then chill brownies. Lift from pan and cut into squares.
