Preparing the Dough

1. Cream the Butter and Sugars: In a large bowl, use a standing mixer or hand mixer to beat 1 cup of softened butter, 1 cup of sugar, and 2/3 cup of brown sugar together until light and fluffy. This step is crucial for achieving that perfect chewy texture.
2. Add the Eggs and Vanilla: Mix in 2 large eggs and 1 teaspoon of vanilla extract until well combined. This adds richness and depth of flavor to the dough.
3. Combine the Dry Ingredients: In a separate bowl, whisk together 3 1/4 cups of all-purpose flour, 4 packages (or 3/4 cup) of hot cocoa mix, 1 teaspoon of salt, 1 teaspoon of baking soda, and 2 teaspoons of baking powder. Gradually add the dry ingredients to the butter mixture, mixing until just blended.

Chilling the Dough: Why It’s Important

Cover the dough and refrigerate for at least 30 minutes, up to 24 hours. Chilling the dough helps the flavors meld together and prevents the cookies from spreading too much during baking, resulting in a thicker, chewier cookie.

Baking to Perfection

1. Preheat the Oven: When ready to bake, preheat your oven to 350°F (175°C).
2. Shape the Cookies: Drop 2 tablespoons of dough per cookie onto baking sheets lined with silicone baking mats or parchment paper. Space the cookies about 2 inches apart to allow for spreading.
3. Bake: Bake in the preheated oven for 9 to 11 minutes, or until the edges are lightly browned. The centers may look slightly underdone, but they’ll firm up as they cool.
4. Cool: Let the cookies cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.
