1. Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

2. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.

3. Beat in the eggs one at a time, then add the vanilla extract, mixing until well combined.

4. In another bowl, whisk together the flour, baking soda, baking powder, and salt.

5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

6. Gently fold in the crushed peppermint candies, chopped Oreo cookies, and semi-sweet chocolate chips until evenly distributed throughout the dough.

7. Drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart to allow for spreading.

8. Bake in the preheated oven for 10-12 minutes, or until the edges are golden brown and the centers are just set.

9. Remove the cookies from the oven and let them cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

10. Serve the cookies once cooled, and enjoy the holiday flavors of Christmas peppermint and Oreo.
