Here's a comprehensive guide on how to bake delicious chocolate chip bar cookies:

== Ingredients ==

For a standard 9x13 inch pan of chocolate chip cookie bars, you'll need:

- 2 1/4 cups all-purpose flour 
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 cup (2 sticks) unsalted butter, melted and cooled slightly
- 3/4 cup granulated sugar
- 3/4 cup packed brown sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 2 cups semi-sweet chocolate chips

== Instructions ==

1. Preheat the oven to 350°F (175°C). Grease a 9x13 inch baking pan or line it with parchment paper.

2. In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.

3. In a large bowl, combine the melted butter, granulated sugar, and brown sugar. Whisk until well blended and smooth.

4. Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract.

5. Gradually stir the dry ingredients into the wet ingredients, mixing just until combined. Do not overmix.

6. Fold in the chocolate chips, reserving a handful to sprinkle on top if desired.

7. Spread the batter evenly into the prepared pan. If reserved, sprinkle the remaining chocolate chips on top.

8. Bake for 25-30 minutes, until the edges are lightly browned and a toothpick inserted into the center comes out with a few moist crumbs.

9. Allow to cool in the pan for at least 30 minutes before cutting into bars.

== Tips for Perfect Cookie Bars ==

- Use melted butter for a chewier texture. The melted butter coats the flour, creating a denser, chewier bar[1].

- Don't overbake. The bars may look slightly underdone in the center when you take them out, but they will continue to set as they cool[2].

- For extra flavor, try browning the butter before adding it to the sugar[7].

- Add a sprinkle of flaky sea salt on top just after baking for a flavor boost[1].

- For thicker bars, use a 9x9 inch pan instead of a 9x13[6].

- Mix up the add-ins - try different types of chocolate chips, nuts, or dried fruit[1].

== Variations ==

- Brown Butter Chocolate Chip Cookie Bars: Brown the butter before adding it to the sugar for a rich, nutty flavor[7].

- M&M Cookie Bars: Substitute half the chocolate chips with M&Ms[5].

- Gluten-Free: Use a 1:1 gluten-free flour blend in place of the all-purpose flour[6].

- Double Chocolate: Add 1/4 cup cocoa powder to the dry ingredients for a chocolate base[2].

== Storage ==

Store cooled cookie bars in an airtight container at room temperature for up to 5 days. For longer storage, wrap tightly and freeze for up to 3 months[4].
