01 - Preheat oven to 350°F (175°C). Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
03 - In a large bowl, beat softened butter, granulated sugar, and brown sugar together until the mixture is light and creamy.
04 - Add eggs one at a time, mixing thoroughly after each addition. Blend in vanilla and peppermint extracts.
05 - Gradually add the dry ingredients to the wet mixture, mixing until just combined to avoid overworking the dough.
06 - Gently fold in chocolate chips and crushed peppermint candies until evenly distributed.
07 - Drop tablespoon-sized balls of dough onto prepared baking sheets, spacing each portion approximately 2 inches apart.
08 - Optionally, sprinkle extra crushed peppermint on top. Bake for 9 to 11 minutes, until the edges are lightly golden and centers remain soft.
09 - Allow baked cookies to cool on the sheet for 5 minutes before transferring to a wire rack to cool completely.
