01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium mixing bowl, whisk together the all-purpose flour, baking soda, and salt. Set aside.
03 - In a large bowl, beat the softened butter, granulated sugar, and brown sugar with an electric mixer or sturdy whisk until light and creamy.
04 - Add eggs one at a time, beating well after each addition. Mix in the pure vanilla extract and peppermint extract until fully combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing.
06 - Gently fold in the semi-sweet chocolate chips and crushed peppermint candies.
07 - Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing each about 2 inches apart.
08 - Optionally, sprinkle additional crushed peppermint over the tops of the dough balls for decoration.
09 - Bake in the preheated oven for 9 to 11 minutes, until the edges are lightly golden but the centers remain soft.
10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire cooling rack to cool completely.
