Ingredients

2 1/4 cups (280 grams) all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 cup (226 grams) unsalted butter, softened

+/ 1 cup (200 grams) packed light brown sugar

1/2 cup (100 grams) granulated sugar
2 large eggs
2 teaspoons vanilla extract
1 1/2 cups (270 grams) semi-sweet chocolate chips

Instructions

Preheat your oven to 350°F (175°C). Grease or line a 9×13 inch baking dish with parchment paper for easy removal.

In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large mixing bowl, beat the softened butter, brown sugar, and granulated sugar together until creamy and well combined, about 2-3 minutes.
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.

Gradually add the dry ingredients to the wet ingredients, mixing just until combined. Do not overmix, as this can make the bars tough.
Fold in the chocolate chips evenly into the batter.
Pour the batter into the prepared baking dish and spread it out evenly with a spatula.
Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crumbs.

Remove from oven and let cool in the pan for about 10 minutes. Then, transfer to a wire rack or cut directly in the pan into squares. Allow to cool completely before slicing if you want cleaner edges.

Tips

For softer, chewier bars, use slightly melted butter instead of softened. For crispier edges, bake a little longer or increase oven temperature slightly.
You can substitute dark chocolate chips, white chocolate chips, or add nuts like walnuts or pecans for variation.

Be careful not to overmix the batter once the dry ingredients are added; overmixing can result in tougher cookies.
If you prefer gooey centers, slightly underbake and let the bars sit for 10 minutes after removing from the oven.

Serving Suggestions

Serve these cookie bars warm with a scoop of vanilla ice cream or a drizzle of caramel for extra indulgence. They also pair well with a cold glass of milk or a cup of coffee. For a more festive presentation, sprinkle some colorful sprinkles or chopped nuts on top before baking.

Variations

Experiment by adding ingredients such as chopped nuts, shredded coconut, or peanut butter chips to customize your cookie bars. You can also swirl in caramel or peanut butter before baking for added flavor. For a healthier twist, substitute some of the flour with oats or use dark chocolate chips.

Storage and Reheating

Store the cookie bars in an airtight container at room temperature for up to 3 days for optimal freshness. To keep them moist, place a slice of bread in the container. For longer storage, wrap tightly in plastic wrap and freeze for up to 3 months. Reheat individual slices in the microwave for 10-15 seconds for a warm, gooey treat or enjoy them at room temperature.

Frequently Asked Questions

Can I make these cookie bars gluten-free?

Yes, substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup like regular flour. Ensure the chocolate chips are also gluten-free. The texture may vary slightly, but they will still be delicious.

How do I prevent the bars from sticking to the pan?

Line your baking dish with parchment paper or lightly grease it with butter or non-stick spray. This ensures easy removal and clean slicing. Using parchment paper is especially helpful for lifting out the entire batch to cut into neat squares.

Can I freeze the cookie dough instead of baking immediately?

Absolutely. Shape the dough into a disk, wrap tightly in plastic wrap, and freeze for up to 3 months. When ready to bake, let it thaw slightly or bake directly from frozen, adding extra minutes to the baking time as needed.

Is it okay to use an 8×8 or 11×7 dish instead of 9×13?

Yes, but the baking time will need adjustment. A smaller dish like 8×8 will result in thicker, more cake-like bars and may require an extra 5-10 minutes of baking. An 11×7 will produce thinner, crisper bars and may bake slightly faster.

How do I know when the cookie bars are done?

Look for golden edges and a slightly set center. Insert a toothpick into the middle—if it comes out with moist crumbs but no wet batter, they’re ready. Overbaking can make them dry, so keep an eye on the timer.

Enjoy baking these easy, crowd-pleasing chocolate chip cookie bars that are perfect for any occasion. Their simple ingredients and straightforward steps make them a go-to dessert for both beginners and experienced bakers alike.
