- 1 cup Unsalted Butter
- 1 cup Granulated Sugar
- 1 cup Light Brown Sugar
- 1 Large Egg
- 1 Egg Yolk
- 2 teaspoons Vanilla Extract
- 2 tablespoons Instant Espresso Powder or Instant Coffee Granules
- 2 1/4 cups All-Purpose Flour
- 1 teaspoon Baking Soda
- 1/2 teaspoon Salt
- 1 cup Semi-Sweet or Dark Chocolate Chips (Optional)
- 1 1/2 cups Powdered Sugar (for the glaze)
- 2 tablespoons Milk (any kind for the glaze)
- 1 teaspoon Instant Espresso Powder or Vanilla Extract (for the glaze)
- Brown the Butter: Begin by melting your unsalted butter in a light-colored saucepan over medium heat. Stir constantly until it reaches a rich amber color with distinct brown specs and smells nutty. Remove from heat and let cool for 10-15 minutes.
- Combine Wet Ingredients: In a large mixing bowl, combine the cooled brown butter, granulated sugar, and light brown sugar. Whisk for about 1-2 minutes until well combined.
- Add Eggs and Flavor: Beat in the large egg and extra egg yolk one at a time, mixing well after each addition. Stir in the vanilla extract and instant espresso powder until dissolved.
- Whisk Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt until there are no lumps.
- Combine Wet and Dry: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. If using, gently fold in the chocolate chips.
- Prepare for Baking: Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper and lightly grease it.
- Spread the Dough: Pour the cookie dough into the prepared pan and spread it evenly.
- Bake: Bake for 22-28 minutes, or until the edges are golden brown and the center is slightly soft. A toothpick should come out with moist crumbs.
- Cool Completely: Let the bars cool completely in the pan on a wire rack for 1-2 hours.
- Prepare the Glaze: Whisk together the powdered sugar, milk, and instant espresso powder or vanilla extract until smooth.
- Glaze and Set: Pour the glaze over the cooled bars and spread it evenly. Let it set for 15-30 minutes before lifting the bars out of the pan.
- Cut and Serve: Once the glaze is set, cut the bars into squares or rectangles and enjoy!

Keywords: Be patient while browning the butter for maximum flavor. Use instant espresso powder for the best coffee flavor, and measure flour correctly to avoid dry bars. Do not overmix the dough and avoid overbaking for chewy texture.
