Preheat your oven to 350°F (175°C). This ensures that your cookies bake evenly and achieve that perfect golden color.
In a large mixing bowl, whisk together the melted butter, granulated sugar, and light brown sugar until well combined. Add the eggs one at a time, mixing thoroughly after each addition. Stir in the vanilla extract.
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, mixing until just combined. Be careful not to overmix!
Gently fold in the mini chocolate chips and chopped Andes Mints until evenly distributed throughout the dough.
Using a cookie scoop or tablespoon, drop rounded balls of dough onto a lined baking sheet, spacing them about 2 inches apart. Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may look slightly underbaked, but they’ll continue to cook on the baking sheet.
Remove the cookies from the oven and allow them to cool on the baking sheet for 5 minutes before transferring them to a cooling rack. Enjoy your Mint Chocolate Chip Cookies warm or at room temperature!
