Step 1: Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This step is crucial for achieving the right texture, so ensure the mixture is well combined and airy.
Step 2: Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract. Ensure each egg is fully incorporated before adding the next to maintain a smooth batter consistency.
Step 3: Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This ensures even distribution of the leavening agent and salt throughout the dough.
Step 4: Gradually Add Dry Ingredients to Wet Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix, as this can result in tough cookies.
Step 5: Stir in Chocolate Chunks: Gently fold in the semi-sweet chocolate chunks until they are evenly distributed throughout the dough. Avoid overmixing, as this can cause the chocolate to melt and streak the dough.
Step 6: Chill the Dough (Optional): For best results, cover the dough and chill in the refrigerator for at least 30 minutes. This allows the flavors to meld and prevents the cookies from spreading too thin during baking.
Step 7: Preheat Oven and Prepare Baking Sheet: Preheat oven to 375F (190C). Line a baking sheet with parchment paper or a silicone baking mat.
Step 8: Drop Dough onto Baking Sheet: Drop rounded tablespoons of dough onto the prepared baking sheet, leaving about 2 inches between each cookie. This spacing allows the cookies to spread without running into each other.
Step 9: Bake the Cookies: Bake for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft. Keep a close eye on the cookies to prevent overbaking.
Step 10: Cool and Serve: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Serve warm and enjoy!
Tip: For a richer flavor, try using a combination of semi-sweet and dark chocolate chunks. For a softer cookie, slightly underbake by a minute or two. The dough can be made ahead of time and stored in the refrigerator for up to 3 days.
