There are few desserts as universally loved as chocolate chip cookies. They are nostalgic, comforting, and perfect for almost any occasion. But sometimes, you want all the flavor and texture of homemade cookies without the extra effort of chilling dough, rolling individual cookie balls, or baking multiple trays.
That is exactly why these Soft and Chewy Chocolate Chip Cookie Bars deserve a permanent place in your dessert rotation.
These cookie bars deliver everything people love about classic chocolate chip cookies: buttery richness, golden edges, a soft center, and plenty of melted chocolate in every bite. The difference is that the dough is pressed into a baking pan and baked as one large batch. After baking, the bars are sliced into squares, making them incredibly convenient for family gatherings, school events, bake sales, parties, or simply keeping a sweet treat on hand throughout the week.
One of the best things about cookie bars is their texture. Because the dough bakes together in a single pan, the centers stay extra soft and chewy while the edges develop a lightly golden finish. The result is a dessert that feels like the perfect combination of a bakery-style cookie and a homemade blondie.
Whether you are an experienced baker or just getting started, this recipe is straightforward, reliable, and rewarding. No special equipment is required, and the dough comes together quickly using basic pantry ingredients.

Ingredients
Dry Ingredients
- 2 1/2 cups all-purpose flour
- 1 teaspoon cornstarch
- 1 teaspoon baking soda
- 1 teaspoon salt
Wet Ingredients
- 1 cup unsalted butter, melted and slightly cooled

- 2 teaspoons pure vanilla extract

Why These Cookie Bars Work
The secret to achieving a soft and chewy texture comes down to ingredient balance.
Brown sugar contains more moisture than granulated sugar, which helps create a softer cookie bar. Cornstarch contributes tenderness and helps prevent the bars from becoming overly firm. Melted butter creates a rich flavor and chewy consistency, while the combination of baking soda and proper baking time ensures a thick but soft texture. These techniques are commonly used in chewy cookie recipes and help produce a consistently tender result.
Equipment Needed
- 9×13-inch baking pan
- Parchment paper
- Large mixing bowl
- Whisk
- Rubber spatula
- Measuring cups and spoons
Instructions
1. Prepare the Baking Pan
Preheat your oven to 350°F (177°C).
Line a 9×13-inch baking pan with parchment paper, leaving some overhang on the sides. This will make it easier to lift the bars out of the pan after baking.
Lightly grease any exposed areas of the pan if desired.
2. Combine the Dry Ingredients
In a medium bowl, whisk together:
- Flour
- Cornstarch
- Baking soda
- Salt
Mix until evenly combined and set aside.
Properly mixing the dry ingredients helps distribute the leavening agents evenly throughout the dough.
3. Mix the Butter and Sugars
In a large mixing bowl, combine the melted butter, granulated sugar, and brown sugar.
Whisk until the mixture looks smooth and glossy.
The melted butter creates a richer texture and contributes to the chewy consistency that makes these bars so irresistible.
4. Add the Eggs and Vanilla
Add the eggs one at a time, whisking well after each addition.
Stir in the vanilla extract.
The mixture should become smooth, creamy, and slightly lighter in color.
5. Incorporate the Dry Ingredients
Gradually add the flour mixture to the wet ingredients.
Using a spatula or wooden spoon, gently stir until no dry streaks remain.
Avoid overmixing. Excessive mixing can lead to tougher cookie bars because it develops more gluten in the flour.
6. Fold in the Chocolate Chips
Add the chocolate chips and gently fold them into the dough.
Try to distribute them evenly so that every slice contains plenty of chocolate.
At this stage, the dough will be thick but spreadable.
7. Transfer to the Pan
Spread the dough evenly into the prepared baking pan.
Use an offset spatula or the back of a spoon to smooth the surface.
For a bakery-style appearance, sprinkle a few extra chocolate chips on top before baking.
8. Bake
Bake for 30–35 minutes.
The edges should appear lightly golden while the center remains slightly soft.
Do not overbake.
The bars will continue to set as they cool, and removing them at the right time is essential for maintaining a chewy texture.
9. Cool Completely
Place the pan on a wire rack and allow the bars to cool completely.
This cooling period helps the structure finish setting and makes slicing easier.
Once cooled, lift the bars from the pan using the parchment paper overhang.
10. Slice and Serve
Cut into squares or rectangles using a sharp knife.
For clean slices, wipe the knife between cuts.
Sprinkle with flaky sea salt if desired for a sweet-and-salty finish.
Things to Consider
Measure Flour Carefully
Too much flour can make cookie bars dry and dense.
For best results, spoon the flour into the measuring cup and level it off with a knife rather than scooping directly from the bag.
Avoid Overbaking
The bars should still appear slightly soft in the center when removed from the oven.
They will continue cooking from residual heat while cooling.
Overbaking is one of the most common reasons cookie bars lose their signature chewy texture.
Use Room Temperature Eggs
Room temperature eggs blend more smoothly into the batter and help create a more even texture.
If needed, place cold eggs in warm water for 5–10 minutes before using.
Choose Quality Chocolate
Since chocolate is the star ingredient, using good-quality chocolate chips can noticeably improve flavor.
Semi-sweet chocolate offers the perfect balance between sweetness and richness.
Flavor Variations
Double Chocolate Cookie Bars
Replace 1/4 cup of flour with unsweetened cocoa powder for a richer chocolate flavor.
Peanut Butter Chocolate Chip Bars
Add 1/2 cup creamy peanut butter to the wet ingredients before mixing.
Walnut Chocolate Chip Bars
Fold in 1 cup chopped walnuts for additional texture and a nutty flavor.
Salted Caramel Cookie Bars
Drizzle caramel sauce over the batter before baking and finish with flaky sea salt.
Holiday Cookie Bars
Add festive candies, colored chocolate pieces, or seasonal sprinkles for celebrations and parties.
Storage
Room Temperature
Store in an airtight container for up to 5 days.
The bars remain soft and chewy for several days when stored properly.
Refrigerator
Store for up to 1 week in a sealed container.
Allow them to come to room temperature before serving.
Freezer
Freeze individual bars in an airtight container for up to 3 months.
Thaw at room temperature before enjoying.
Serving Suggestions
