Brown Butter Pecan Cinnamon Bars

Ingredients

10 ounces (20 tablespoons) unsalted butter, softened
1 1/2 cups firmly packed light brown sugar
1/2 cup sugar
2 large eggs
2 teaspoons pure vanilla extract
2 cups unbleached all-purpose flour
1 1/2 teaspoons baking powder
2 teaspoons ground cinnamon
1/4 teapsoon kosher salt
2 cups coarsely chopped pecans, toasted

Directions

1. Preheat the oven to 350°F.
2. Grease a 9 by 13-inch square baking pan with non-stick cooking spray.
3. Put the butter in a medium pot and cook over medium low to medium heat until golden brown, stirring frequently and making sure to scrape the bottom of the pan. As soon as it becomes golden brown remove it from the heat and pour it into a bowl to stop more coloring. (If any of the bits are black strain the butter.) Set aside.
4. Whisk together the sugars, eggs and vanilla extract. Whisk in the butter in a steady stream. Add the flour, baking powder, cinnamon, salt and pecans. Stir until everything is evenly blended.
5. Spread the batter evenly into the prepared pan. (You can also place a piece of plastic wrap on top of the dough and press it evenly into the pan.)
6. Bake until a toothpick inserted into the center of the batter just comes out clean, about 20 minutes. Do not overcook or they will be dry. Let cool to room temperature then cut into pieces, small or big depending on your appetite.
