Elsa's Brownies

Directions

1. 1
   Position an oven rack in the middle of the oven and preheat the oven to 350 degrees F. Line a 9-inch square baking dish with foil and grease with cooking spray.
2. 2
   Melt the semisweet chocolate and butter in a medium heatproof bowl set over a saucepan of simmering water, stirring occasionally until smooth.
3. 3
   Beat together the sugar and eggs in a stand mixer on medium-high speed until creamed, about 3 minutes.
4. 4
   Pour in the chocolate mixture and whisk until combined well.
5. 5
   Mix in the flour, baking powder and salt for about 2 minutes on medium speed.
6. 6
   Stir in the bittersweet chocolate chunks and transfer the batter to the prepared baking dish.
7. 7
   Bake until the top is shiny and set and the sides have begun to pull away slightly, about 35 minutes for fudgy brownies.
