- Heat the oven to 350°F (175°C). Grease a 9x13-inch pan and line it with parchment, leaving overhang on the long sides.
- Melt the butter in a light-colored saucepan over medium heat. Keep cooking, swirling the pan, until it foams, smells nutty and the bits on the bottom turn golden brown.
- Pour the brown butter and all the browned bits into a large bowl right away so it stops cooking.
- Whisk the brown sugar into the butter until smooth, then let it cool.
- Whisk in the eggs one at a time, then the vanilla.
- Add the flour, baking powder and salt and fold with a spatula until just combined.
- Fold in the chocolate chips and pecans, if using.

- Spread the batter evenly in the pan. It will be thick, so use the spatula to push it into the corners.
- Bake until the edges are golden and pulling away from the pan and a toothpick in the center comes out with moist crumbs.
- Cool completely in the pan on a rack before cutting into 24 bars.
