Step 1: Preheat and Prep: Preheat oven to 375F (190C). Line a baking sheet with parchment paper. This prevents sticking and ensures even baking.
Step 2: Cream Butter and Sugars: In a large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy. This incorporates air, creating a tender cookie. A stand mixer or hand mixer can be used for this step.
Step 3: Add Wet Ingredients: Beat in the vanilla extract and milk until well combined. The milk acts as a binding agent, replacing the moisture and emulsification typically provided by eggs.
Step 4: Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, and salt. This ensures even distribution of the leavening agent and salt throughout the dough.
Step 5: 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 develop the gluten in the flour and result in tough cookies.
Step 6: Stir in Chocolate Chips: Fold in the chocolate chips until evenly distributed throughout the dough.
Step 7: Drop by Rounded Tablespoons onto Baking Sheet: Drop rounded tablespoons of dough onto the prepared baking sheet, leaving about 2 inches between each cookie.
Step 8: Bake: Bake for 10-12 minutes, or until the edges are golden brown and the centers are still slightly soft.
Step 9: Cool: Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
For a chewier cookie, use melted butter instead of softened butter. For a cakier cookie, add an extra tablespoon of milk. Different types of chocolate chips, such as dark chocolate, white chocolate, or peanut butter chips, can be substituted for a unique flavor. Chopped nuts can be added for texture and flavor.
