- 1 teaspoon baking soda

Instructions
1. Cream Butter and Sugars
Beat butter, brown sugar, and granulated sugar until light and fluffy (2–3 minutes).
2. Add Wet Ingredients
Mix in eggs one at a time. Add vanilla extract and combine.
3. Mix Dry Ingredients
In a separate bowl, whisk flour, cocoa powder, baking soda, salt, and cornstarch.
Gradually mix dry ingredients into wet mixture until just combined. Do not overmix.
4. Fold in Chocolate Chips
Reserve a small handful of colorful chips for topping.
Gently fold the remaining chips into the dough.
5. Chill
Refrigerate dough for at least 45 minutes.
This step ensures thick cookies and prevents spreading.

7. Bake
