01 - Preheat the oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium mixing bowl, whisk together all-purpose flour, baking soda, and salt. Set aside.
03 - In a large bowl, beat softened butter, granulated sugar, and packed brown sugar with an electric mixer or whisk until light and creamy.
04 - Add eggs one at a time to the creamed mixture, beating well after each addition. Blend in vanilla extract and peppermint extract until fully combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing on low speed or by hand until just combined. Avoid overmixing.
06 - Gently fold in 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 - If desired, sprinkle additional crushed peppermint candies on top of each dough portion for decorative finish.
09 - Bake for 9 to 11 minutes, or until cookie edges are lightly golden and centers remain soft.
10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire cooling rack to set completely.
