Step-by-Step Instructions
- Brown the Butter: Melt ½ cup of unsalted butter over medium heat until it turns golden brown and emits a nutty aroma (about 5-7 minutes). Let cool slightly.
- Mix Wet Ingredients: Combine the cooled brown butter with dark brown sugar and white sugar. Beat until creamy, then mix in the egg, egg yolk, and vanilla extract.
- Combine Dry Ingredients: Whisk together all-purpose flour, espresso powder, baking soda, and salt in a separate bowl.
- Mix Dry into Wet Ingredients: Fold the dry mixture into the wet ingredients gently until no flour streaks remain, then mix in dark chocolate chunks.
- Chill the Dough: Wrap the dough in plastic wrap and refrigerate for at least 30 minutes.
- Preheat and Bake: Preheat oven to 350°F. Scoop the chilled dough onto lined baking sheets, spacing them apart, and bake for 11 minutes.
- Cool: Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack. Sprinkle with flaky sea salt before serving.
