Step 1
Preheat oven to 350°F and line an 8-inch square metal baking pan with parchment paper.
Step 2
Whisk together flour, unsweetened cocoa powder, and salt in a medium bowl.
Step 3
Place chopped chocolate in a medium bowl. Cook butter in a heavy saucepan over medium heat, stirring constantly until it foams, turns clear, and then turns a medium brown, about 5 minutes. Pour brown butter over chocolate and let stand for 1 minute, then stir until chocolate is completely melted and mixture is smooth.
Step 4
Gradually add C&H® Organic Raw Cane Sugar and C&H® Light Brown Sugar, whisking until smooth.
Step 5
Whisk in eggs and egg yolk one at a time, until combined. Whisk in vanilla. Add flour mixture and fold in just until no streaks remain. Fold in chocolate chips.
Step 6
Pour batter into prepared pan and smooth the top. Gently tap pan once to remove air bubbles.
Step 7
Bake brownies for 25 to 28 minutes, until the top is set and a toothpick inserted in the center comes out with a few crumbs attached. Remove from oven and place on a wire rack to cool completely.
Step 8
Lift parchment and place brownies on a cutting board. Cut into squares with a sharp knife. Store leftover brownies in an airtight container at room temperature.
These brownies are delicious topped with flaky salt or served warm with a scoop of vanilla ice cream.
