Creating these incredible Double Chocolate Peppermint Cookies is simple if you follow these steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
2. Cream Butter and Sugars: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Add Eggs and Extracts: Beat in the eggs one at a time, then stir in the vanilla and peppermint extracts until well combined.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, stirring until fully incorporated.
6. Fold in Chocolate Chips: Gently fold in the semi-sweet and white chocolate chips until evenly distributed throughout the dough.
7. Scoop the Dough: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, leaving space between each cookie to allow for spreading.
8. Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers are still soft.
9. Cool: Remove from the oven and let the cookies cool on the baking sheets for about 10 minutes before transferring them to wire racks to cool completely.
10. Garnish: While the cookies are still slightly warm, sprinkle crushed peppermint candies on top for added flavor and festive flair.
