Creating these Mexican Hot-Chocolate Cookies is easy if you follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
2. Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
3. Add Eggs and Vanilla: Beat in the eggs one at a time, followed by the vanilla extract, mixing until well combined.
4. Mix Dry Ingredients: In a separate bowl, whisk together the flour, cocoa powder, baking soda, cinnamon, cayenne pepper, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until just combined.
6. Fold in Chocolate Chips: Gently fold in the semi-sweet chocolate chips to the cookie dough.
7. Scoop Cookies: Use a tablespoon or cookie scoop to drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
8. Bake: Place the baking sheets in the preheated oven and bake for 12-15 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. Dust with Powdered Sugar: Once cooled, dust the cookies with powdered sugar for a beautiful finish.
