03 - In a large bowl, beat the softened butter, granulated sugar, and brown sugar until the mixture is light and creamy.
04 - Add eggs one at a time, beating well after each addition. Blend in vanilla and peppermint extracts.
05 - Gradually add the dry ingredients to the wet ingredients, mixing gently just until combined.
06 - Fold in the semi-sweet chocolate chips and crushed peppermint candies.
07 - Scoop tablespoon-sized portions of dough onto the prepared baking sheets, spacing cookies about 2 inches apart.
08 - Sprinkle extra crushed peppermint candies on top of dough balls, if desired, for decoration.
09 - Bake for 9 to 11 minutes, or until the edges are lightly golden but centers remain soft.
10 - Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
