- 8oz (1 Cup) Unsalted Butter
- 150 grams (3/4 Cup) Light Brown Sugar
- 100 grams (1/2 Cup) Granulated Sugar
- 2 Teaspoons Pure Vanilla Extract
- 1 Large Egg + 1 Large Egg Yolk, at room temperature
- 250 grams (2 Cups) All-Purpose Flour/ Plain Flour
- 1/2 Teaspoon Baking Powder
- 1/4 Teaspoon Salt
- 1 Teaspoon Cornstarch/ Cornflour
Instructions
- Preheat oven to 350F/180C and line an 8-inch square or 9-inch square baking pan with aluminum foil or parchment paper, if using foil make sure to spray with non-stick spray then set the pan aside.
- In a light-colored medium-sized pot over low-medium heat add the butter and cook to "brown the butter" This process will take anywhere from 5-15 minutes depending on the size of your post, be careful not to burn it as the butter turns from brown to burnt very quickly. Check out this post for an in-depth look at browning butter. You will start to smell a nutty aroma and the butter will become a golden brown color. Turn off and pour into a heatproof bowl to cool for 5 minutes.
- Add the sugars to the butter and mix to combine. Next add the egg, egg yolk, and vanilla whisk together for a minute or two you want the color of the batter to lighten. Add flour, baking powder, salt, and cornstarch, and gently mix until no flour streaks remain. Pour into the prepared pan.
- Bake for 19-22 minutes or until a toothpick inserted comes out clean, you do not want to overbake. Let cool on a wire rack for 20 minutes before gently removing from the pan and slicing into bars. Store leftovers in an airtight container.
