Preheat your oven to 375°F (190°C). Line baking sheets with parchment paper for easy cleanup and even baking.

In a bowl, whisk together flour, baking soda, and salt. Set aside. This ensures the leavening agent is evenly distributed.

In a separate bowl, beat butter, granulated sugar and brown sugar until creamy and fluffy. This adds air for soft, tender cookies.

Add eggs one at a time, then add vanilla extract. Beat until smooth and fully incorporated. This gives the dough richness and flavor.

Gradually mix dry ingredients into the butter mixture. Stir until just combined. Overmixing can make cookies tough.

Fold in chocolate chips and nuts (if using). Ensure chips are evenly distributed for perfect bites in every cookie.

Use a cookie scoop or spoon to place dough on prepared baking sheets. Leave 2 inches between cookies for spreading.

Bake in the preheated oven for 12–14 minutes. Cookies should be lightly golden around the edges and soft in the center.

Let cookies cool on the baking sheet for 5 minutes, then transfer to a cooling rack. This prevents sticking and preserves texture.

Serve warm with milk or store cooled cookies in an airtight container. They stay soft for several days.
