Method
- Melt the butter in a light colored saucepan over medium heat until it foams and golden specks appear. Pour the hot liquid into a large heatproof mixing bowl to stop the cooking process.
- Combine the warm brown butter with the dark brown sugar and whisk vigorously until smooth. Add the whole egg, the extra egg yolk, and the vanilla extract, beating until glossy.
- Add the all purpose flour, baking powder, and salt directly into the wet ingredients. Stir gently with a rubber spatula just until no dry flour streaks remain visible.
- Fold the semi sweet chocolate chips gently into the thick batter so they distribute evenly. Save a small handful to press into the top of the dough.
- Transfer the batter into a parchment lined square baking pan and smooth into an even layer. Bake at 350 degrees Fahrenheit for 25 minutes until the edges are golden and the center is set.

Notes
Store covered in an airtight container at room temperature for up to 4 days. Do not overbake; pull them out when the center is still slightly soft.
