Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes using an electric mixer.
Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
In another bowl, whisk together the all-purpose flour, baking soda, and salt.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Fold in the chocolate chips and crushed peppermint candies until evenly distributed.
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheet, leaving space between each cookie.
Bake for 10-12 minutes or until the edges are lightly golden. The centers may appear slightly underbaked; they will set as they cool.
Remove from the oven and let cool on the baking sheet for 5 minutes before transferring to a cooling rack to cool completely.
