Step-by-Step Instructions
1. Preheat the Oven
Preheat your oven to 410°F (210°C).
Line baking sheets with parchment paper to prevent sticking and encourage even baking.
2. Cream the Butter and Sugars
In a large mixing bowl, combine the cold cubed butter, granulated sugar, and brown sugar.
Mix until the ingredients are fully combined and slightly creamy.
Using cold butter helps create the thick bakery-style texture these cookies are known for.
3. Add Eggs and Vanilla
Add the eggs one at a time, mixing well after each addition.
Stir in the vanilla extract until incorporated.
4. Prepare the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
This ensures even distribution of the leavening agents throughout the dough.
5. Combine Wet and Dry Mixtures
Gradually add the dry ingredients to the butter mixture.
Mix until just combined to avoid overworking the dough.
6. Fold in Chocolate Chips and Walnuts
Fold the chocolate chips and chopped walnuts into the dough evenly.
The walnuts add crunch and help balance the sweetness, but they can be omitted if preferred.
