Creating your own batch of Hot Chocolate Cookies is a fun and straightforward process. Follow these steps to ensure your cookies turn out perfectly:

1. Preheat Your Oven: Begin by preheating your oven to 350°F (175°C). Line two baking sheets with parchment paper.

2. Mix the Butters and Sugars: In a large mixing bowl, cream the softened butter, granulated sugar, and brown sugar together using a hand mixer or stand mixer until light and fluffy.

3. Add Eggs and Vanilla: Incorporate the eggs one at a time, mixing well after each addition. Then, add the vanilla extract and beat until well blended.

4. Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, cocoa powder, baking soda, and salt.

5. Combine Wet and Dry Mixtures: Gradually add the dry mixture to the wet mixture. Mix until just combined, being careful not to over-mix the dough.

6. Fold in Chocolate Chips and Marshmallows: Gently fold in the semi-sweet chocolate chips and mini marshmallows until evenly distributed throughout the dough.

7. Scoop the Dough: Using a cookie scoop or tablespoon, drop dough onto the prepared baking sheets, leaving space between each cookie to allow for spreading.

8. Bake: Place the baking sheets in the preheated oven and bake for 10-12 minutes, or until edges are set and tops are slightly cracked.

9. Cool the Cookies: Remove from the oven and let the cookies cool on the baking sheets for 5-10 minutes before transferring them to wire racks to cool completely.

10. Dust with Powdered Sugar (Optional): For an extra touch, gently dust the cookies with powdered sugar before serving.
