01 - Preheat 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 mixing bowl, beat together the softened butter, granulated sugar, and brown sugar until the mixture is light and creamy.
04 - Add eggs one at a time to the creamed mixture, beating well after each addition. Blend in the vanilla extract and peppermint extract until evenly combined.
05 - Gradually add the dry ingredients to the wet mixture, mixing only until the dough begins to come together. Avoid overmixing.
06 - Fold in the semi-sweet chocolate chips and crushed peppermint candies until evenly distributed throughout the dough.
07 - Scoop rounded tablespoon-sized portions of dough onto the prepared baking sheets, spacing about 2 inches apart.
08 - If desired, sprinkle additional crushed peppermint candies over the tops of the dough balls for decoration.
09 - Bake for 9 to 11 minutes until the edges are lightly golden and the centers remain soft.
10 - Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
