Before you begin, preheat your oven to 375°F (190°C). Line your baking sheets with parchment paper or silicone baking mats to prevent sticking and ensure even baking.

2. Mix the Dry Ingredients

In a medium bowl, combine the flour, baking soda, and salt. Whisk them together to distribute the leavening agent evenly. Set aside.

3. Cream the Butter and Sugars

In a large mixing bowl, beat the butter, granulated sugar, brown sugar, and vanilla extract until the mixture is light and fluffy. This step is crucial as it helps incorporate air, resulting in a perfect cookie texture.

4. Add the Eggs

One at a time, add the eggs, beating well after each addition. This ensures the dough is smooth and well combined.

5. Combine Wet and Dry Mixtures

Gradually add the dry ingredients to the wet mixture. Use a spatula or the mixer on low speed to avoid overmixing, which can result in tougher cookies.

6. Fold in the Chocolate Chips

Gently fold in the chocolate chips and nuts (if using). Make sure they are evenly distributed throughout the dough.

7. Chill the Dough (Optional)

For thicker cookies, refrigerate the dough for at least 30 minutes. This step helps prevent spreading during baking.

8. Shape the Cookies

Use a cookie scoop or tablespoon to drop dough onto the prepared baking sheets, spacing them about 2 inches apart.

9. Bake to Perfection

Bake in the preheated oven for 9-11 minutes or until the edges are golden brown but the centers still look slightly underdone. This ensures the chewy texture we all love.

10. Cool and Serve

Allow the cookies to cool on the baking sheets for 2 minutes before transferring them to wire racks to cool completely. Serve warm for the ultimate experience.
