01 - Preheat oven to 350°F (175°C). 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 - Using an electric mixer or sturdy whisk in a large bowl, beat softened butter, granulated sugar, and brown sugar together until light and creamy.
04 - Add eggs one at a time, mixing well after each addition. Blend in vanilla extract and peppermint extract until fully combined.
05 - Gradually mix the dry ingredients into the wet ingredients until just combined, avoiding overmixing.
06 - Gently fold in semi-sweet chocolate chips and crushed peppermint candies until evenly distributed throughout the dough.
07 - Scoop rounded tablespoonfuls of dough and place onto prepared baking sheets, spacing about 2 inches apart. Optionally, sprinkle additional crushed peppermint on top for decoration.
08 - Bake for 9 to 11 minutes until the edges are lightly golden and centers are set but soft.
09 - Allow cookies to cool on the baking sheets for 5 minutes before transferring to a wire cooling rack to cool completely.
