1. Preheat Oven: Set your oven to 350 °F and line baking sheets with parchment paper.

2. Mix Dry Ingredients: In a bowl, whisk together the flour, baking soda, and salt.

3. Cream Butter & Sugars: In a separate large bowl, beat the softened butter with brown sugar and granulated sugar until light and fluffy.

4. Add Eggs & Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract.

5. Combine: Gradually blend the dry ingredients into the wet mixture until just combined.

6. Add Chips & Peppermint: Fold in the semi-sweet chocolate chips, white chocolate chips, and crushed peppermint candies.

7. Scoop & Bake: Drop dough by rounded tablespoon onto the prepared baking sheets, spacing about 2 inches apart. Bake for 10-12 minutes, or until the edges are lightly golden but the centers remain soft.

8. Cool: Let the cookies rest on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

9. Serve & Enjoy: Serve these festive cookies with a cold glass of milk or your favorite warm beverage for a cozy winter treat.
