ATK GF Fudgy Brownies

4 oz. (.75 cup + 2 Tbsp.) ATK GF Flour blend
.5 tsp. salt
.5 tsp. xanthan gum
7 oz. semisweet chocolate, chopped coarse
8 Tbsp. unsalted butter, cut into 8 pieces.
3 Tbsp. unsweetened cocoa powder
8.75 oz. (1.25 cups) sugar
3 large eggs
2 tsp. vanilla

*Make foil sling (lay two sheets of foil in pan perpendicular to each other, with extra foil hanging over edges of pan.  Push foil into corners and up sides of pan, smoothing foil flush to pan.) for 8-inch square baking pan; spray with cooking spray.  Whisk flour blend, salt, and xanthan gum together in bowl; set aside.  Microwave chocolate, butter, and cocoa in bowl at 50% power, stirring often, until melted and smooth, 1-3 minutes.  Let mixture cool slightly.  Whisk sugar, eggs, and vanilla together in large bowl.  Whisk in cooled chocolate mixture.  Stir in flour mixture using rubber spatula and mix until well combined.  Scrape batter into prepared pan and smooth top with spatula.  Cover pan with plastic wrap and let batter rest for 30 minutes.

Adjust oven rack to middle position and heat over to 350*.  Remove plastic and bake until toothpick inserted in center comes with with few moist crumbs attaches, 45-55 minutes, rotating pan halfway through baking.  Let browning cool completely in pan on wire rack, about 2 hours.  Using foil overhand, lift brownies out of pan.  Cut into squares and serve.  Browning are best eaten on day they are baked, but they can be cooled and placed immediately in airtight container and stored at room temperature for up to 2 days.
