In a saucepan over medium heat, melt the butter and continue cooking until it turns golden brown and has a nutty aroma, about 5-7 minutes. Remove from heat and let cool slightly.

In a mixing bowl, combine the browned butter, brown sugar, and granulated sugar. Whisk until smooth. Add the egg and bourbon, mixing until fully incorporated.

In another bowl, whisk together the flour, baking soda, and salt.

Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Fold in the chocolate chips.

Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper. Scoop tablespoon-sized balls of dough onto the prepared baking sheet, spacing them about 2 inches apart. Bake for 10-12 minutes or until the edges are golden brown.

Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
