Chocolate Brown-Sugar Brownies

Ingredients:
2 sticks unsalted butter
4 ounces unsweetened chocolate, coarsely chopped
4 large eggs
1 cup granulated sugar
1 cup packed light brown sugar
1 teaspoon pure vanilla extract
3/4 cup all-purpose flour
1 cup pecans, coarsely chopped

*Directions:

_Preheat the oven to 350 degrees F. Butter and lightly flour a 9-by-13-inch baking dish. In the top of a double boiler, melt the butter with the chocolate; let cool.
_Meanwhile, in a large bowl, beat the eggs with the granulated sugar and brown sugar until thickened; beat in the vanilla. Using a rubber spatula, gently fold in the chocolate mixture until combined. Sift the flour over the batter and fold it in. Fold in the pecans.
_Pour the batter into the prepared pan and bake for about 25 minutes, or until a tester inserted in the center comes out with moist crumbs attached. Let the brownies cool in the pan for 1 hour before cutting into squares.
