Bad Ass Brownies

Easy and rich.

Ingredients

• 1 cup (2 sticks) unsalted butter
• 2 1/2 cups sugar
• 1 1/2 cups unsweetened cocoa powder
• 1 teaspoon salt
• 2 teaspoon vanilla extract
• 4 large eggs
• 2/3 cup all-purpose flour
• 1 bag 60% cacao dark chocolate chips (I like Ghirradelli for these)
• Chopped walnuts

Preparation

• Preheat oven to 325°. Grease a 9 x 13 x2 glass baking dish with butter. ( I use the wrappers of the butter)
• Melt butter in a small sauce-pan over medium heat, or melt in microwave. Let cool slightly. Whisk sugar, cocoa, and salt in a medium bowl to combine. Pour butter into dry ingredients, whisking constantly to blend. Whisk in vanilla. Add eggs. Add flour and stir until just combined (do not overmix). Scrape batter into prepared pan with rubber spatula, smooth top. Batter will be stiff. Smooth batter out into the corners, then throw some crushed nuts onto the surface of the brownies (a couple of handfuls).  Then throw on a couple of handfuls of the Ghirradelli 60% cacao dark chocolate chips on the top (about half a bag to 3/4s a bag).  Take the spatula and pat the nuts and chips into the surface of the batter.
• Bake until top begins to crack and a toothpick inserted into the center comes out with a few moist crumbs attached, 45 minutes to an hour. Be careful when you test for doneness, that the toothpick is not going through a chocolate chip, or else the reading will not be right
• Transfer pan to a wire rack; let cool completely in pan.
