Preheat the oven to 375°F (190°C) and line two baking sheets with parchment paper.

In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar until light and fluffy (2-3 minutes).

Add eggs one at a time, mixing well after each. Then mix in the Baileys Irish Cream until smooth.

In another bowl, whisk together the flour, baking soda, and salt. Gradually add to the wet ingredients until just combined.

Fold in the semi-sweet chocolate chips gently to combine.

Drop rounded tablespoons of dough onto prepared sheets, spacing them 2 inches apart.

Bake for 9-11 minutes until edges are lightly browned and centers are set.

Cool on baking sheets for 2 minutes before transferring them to wire racks.
