Preheat your oven to 350°F (175°C). Prepare two baking sheets by lining them with parchment paper.

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

Add the eggs, one at a time, ensuring each egg is fully incorporated. Mix in the vanilla extract until well combined.

In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing just until incorporated. Be careful not to overmix!

Fold in the mint chocolate chips gently. The dough should be slightly sticky.

Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie.

Bake in the preheated oven for 10-12 minutes or until the edges are golden brown, but the centers remain soft.

Let the cookies cool on the baking sheets for about 5 minutes before transferring them to wire racks to cool completely.
