• Ready In: 55mins
• Ingredients: 8
• Yields: 1 9x9 pan
• Serves: 36

ingredients

• 1 1⁄2 cups semi-sweet chocolate chips
• 1 1⁄2 cups chopped white chocolate or 1 1/2 cups white chocolate chips
• 3⁄4 cup butter, room temperature
• 1 cup brown sugar
• 3 large eggs
• 1 teaspoon vanilla extract
• 3⁄4 teaspoon salt
• 2 cups all-purpose flour

directions

1. Preheat oven to 350°F Line a 9×9-inch baking pan with aluminum foil and lightly grease.
2. In a small, microwave safe bowl, melt 1 cup semisweet chocolate by microwaving in 30 second intervals and stirring frequently until chocolate is smooth. Repeat with 1 cup white chocolate in a second small bowl. Set aside.
3. In a large bowl, cream together butter and brown sugar. Beat in the eggs one at a time, waiting until each is fully incorporated before adding the next.
4. Beat in the vanilla, salt and flour, mixing just until all ingredients are combined and no streaks of flour remain.
5. Transfer 2 cups of batter to a medium mixing bowl. Add the melted white chocolate and beat (by hand or with an electric mixer) to combine. Pour into prepared pan.
6. Top evenly with remaining 1/2 cup semisweet chocolate chips and 1/2 cup white chocolate chips.
7. Beat melted semisweet chocolate into remaining batter. Drop small dollops of chocolate batter on top of the chocolate chip layer, then use a spatula to gently spread the chocolate batter into an even layer.
8. Bake for about 35 minutes, until a toothpick inserted into the center comes out with only a few moist crumbs attached.
9. Allow to cool in pan, then lift the brownies out with the foil and slice into long, thin slices (12 slices by 3 slices).
