Double Chocolate Cookies

Instructions

1. Prepare the baking sheets
   Preheat the oven to 350°F (175°C). Line two baking sheets with parchment paper or silicone baking mats and set aside.
2. Cream the butter and sugars
   In a large mixing bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy, about 3 minutes. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until combined.
3. Mix the dry ingredients
   In a separate bowl, whisk together the flour, cocoa powder, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
4. Add the chocolate chips
   Fold in the semi-sweet chocolate chips and white chocolate chips with a rubber spatula until evenly distributed throughout the dough.
5. Form the cookies
   Using a cookie scoop or tablespoon, drop rounded balls of dough (about 2 tablespoons each) onto the prepared baking sheets, spacing them about 2 inches apart.
6. Bake the cookies
   Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers are still slightly soft. The cookies will continue to firm up as they cool.
7. Cool and store
   Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely. Once cooled, store in an airtight container at room temperature for up to 5 days.
