Nutella-Chip Brownies

Directions

1. 1
   Preheat oven to 350 degrees F. Line a 9-inch square baking pan with parchment paper for easy removal. Cover parchment paper with cooking spray.
2. 2
   In a heatproof mixing bowl, melt butter and 11/4 cups chocolate chips in the microwave until smooth. Do this in 15-second intervals, stirring in between to ensure that you do not scorch the chocolate. Once the mixture is melted, stir in the 3/4 cup Nutella. Cool the chocolate mixture until it's at room temperature. Then stir in the brown sugar and vanilla. Add eggs 1 at a time, mixing well after each addition, until mixture is glossy and smooth.
3. 3
   Whisk together the dry ingredients (flour, cocoa, salt and baking powder) in another bowl and then add it into the chocolate mixture. Stir in the remaining 1/2 cup of chocolate chips.
4. 4
   Spread batter evenly into the prepared pan.
5. 5
   Mix remaining Nutella with 1 teaspoon water in a heatproof bowl. Microwave for 15 seconds to thoroughly incorporate both ingredients, continuing to heat for additional 15 seconds until it's smooth.
6. 6
   Drizzle Nutella mixture on top of the brownie batter. Using the tip of a paring knife, create swirls of the Nutella. Do not over mix, as you want to keep the swirls visible.
7. 7
   Bake for 25 to 30 minutes or until a toothpick inserted comes out mostly clean. Cool in pan for at least 10 minutes and cut into 3 inch squares.
