Creating these sheet pan cookies is straightforward with this easy-to-follow guide:

1. Preheat Oven: Preheat your oven to 350°F (175°C). Prepare a 18×13-inch rimmed baking sheet by greasing it or lining with parchment paper.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
3. Cream Butter and Sugars: In a large bowl, beat the softened butter, granulated sugar, and brown sugar together until light and fluffy.
4. Add Eggs and Vanilla: Mix in the eggs, one at a time, followed by the vanilla extract, ensuring everything is well combined.
5. Combine Mixtures: Gradually add the dry ingredients to the butter mixture, mixing until just combined. Be careful not to overmix.
6. Fold in Chocolate Chips: Gently fold in the chocolate chips and nuts if using, ensuring they are evenly distributed throughout the dough.
7. Spread the Dough: Pour the cookie dough onto the prepared baking sheet. Use a spatula or your hands to spread the dough evenly to the edges of the pan.
8. Bake: Place the baking sheet in the preheated oven and bake for 20-25 minutes. You want the edges to be golden brown, while the center remains soft.
9. Cool: Once baked, remove the pan from the oven and allow the cookies to cool in the pan for about 10-15 minutes before slicing into squares or bars.
10. Serve: Enjoy warm or at room temperature. The cookies can be stored in an airtight container for up to a week.
