01 - Preheat oven to 350°F. Line two baking sheets with parchment paper.
02 - In a medium bowl, whisk together the flour, baking soda, and salt until evenly combined. Set aside.
03 - In a large mixing 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 vanilla extract and peppermint extract until fully incorporated.
05 - Gradually add the dry mixture to the wet ingredients, mixing just until combined without overmixing.
06 - Gently fold in chocolate chips and crushed peppermint candies.
07 - Scoop tablespoon-sized balls of dough onto the prepared baking sheets, spacing each about 2 inches apart.
08 - If desired, sprinkle extra crushed peppermint over the tops of the dough balls for decoration.
09 - Bake for 9 to 11 minutes, until the 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 rack to cool fully.
