Ingredients:

• 1 cup (2 sticks) unsalted butter

• 1 cup brown sugar, packed

• 1/2 cup granulated sugar

• 2 large eggs

• 1 teaspoon vanilla extract

• 2 1/4 cups all-purpose flour

• 1/2 teaspoon baking soda

• 1/2 teaspoon salt

• 1 to 1 1/2 cups mix-ins (chocolate chips, chopped nuts, etc.)

Instructions:

1. Brown the Butter:

• In a medium saucepan, melt the butter over medium heat. Once melted, continue to cook, swirling the pan occasionally until the butter turns a golden brown color and has a nutty aroma. Be careful not to burn it. Remove from heat and let it cool for a few minutes.

1. Preheat the Oven:

• Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.

1. Mix the Wet Ingredients:

• In a large mixing bowl, combine the brown butter, brown sugar, and granulated sugar. Mix until well combined and smooth.

1. Add Eggs and Vanilla:

• Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

1. Combine Dry Ingredients:

• In a separate bowl, whisk together the flour, baking soda, and salt.

1. Mix Wet and Dry Ingredients:

• Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix.

1. Add Mix-Ins:

• Fold in your choice of mix-ins, such as chocolate chips or chopped nuts.

1. Form Cookie Dough Balls:

• Scoop tablespoon-sized portions of cookie dough and roll them into balls. Place them on the prepared baking sheets, leaving some space between each.

1. Bake:

• Bake in the preheated oven for 10-12 minutes or until the edges are golden brown. The centers may still be soft, but they will firm up as they cool.

1. Cool:

• Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
