This chewy chocolate chip bar cookies recipe makes soft, buttery cookie bars in a 13-by-9-inch pan with just 15 minutes of preparation and 25 to 30 minutes of baking at 350°F (175°C). The reliable formula uses softened unsalted butter, brown sugar, granulated sugar, eggs, vanilla, flour, baking soda, salt, and semisweet chocolate chips for thick, easy-to-slice bars.
Each square has lightly golden edges, a tender middle, and plenty of melted chocolate in every bite. The secret to keeping these pan cookies chewy is to measure the flour carefully and remove the pan while the center still looks slightly soft, allowing residual heat to finish the bake as the bars cool.

These chewy chocolate chip bar cookies deliver the familiar comfort of classic chocolate chip cookies without requiring you to scoop and shape individual portions. The entire dough is pressed into one pan, so the preparation is quick, the cleanup is simple, and every batch produces a generous supply of shareable squares.
The texture is especially appealing because the bars combine several contrasts in one bite. The edges become lightly golden and pleasantly sturdy, while the middle stays soft, moist, and chewy around pools of semisweet chocolate.
Brown sugar brings a gentle caramel note and helps the centers stay tender, while granulated sugar contributes a delicate crispness around the edges. The butter provides richness, and vanilla rounds out the chocolate flavor without making the cookies taste heavy.

Ingredients You’ll Need
The ingredient list is short, but each item has an important role in the final texture. Use softened butter rather than melted butter so the creamed mixture has enough structure to support thick, chewy bars.
- Unsalted butter: One cup, or 226 grams, creates the rich base and lets you control the salt.
- Light brown sugar: One packed cup, or 200 grams, contributes moisture, color, and a mild caramel taste.
- Granulated sugar: One-half cup, or 100 grams, balances the brown sugar and helps the edges brown.
- Eggs: Two large eggs bind the dough and add tenderness.
- Vanilla extract: One teaspoon gives the chocolate and butter a fuller flavor.
- All-purpose flour: Two and one-quarter cups, or 270 grams, provide the structure for the pan cookies.
- Baking soda: One teaspoon helps the dough spread and brown properly.
- Salt: One-half teaspoon sharpens the sweetness and keeps the flavor balanced.
- Semisweet chocolate chips: Two cups, or 340 grams, ensure chocolate in nearly every slice.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), making sure the rack is positioned in the center. Grease a 13-by-9-inch baking pan or line it with parchment, and let the parchment extend slightly over two sides if you want an easy way to lift out the cooled slab.
Step 2: Add the softened butter, packed light brown sugar, and granulated sugar to a large mixing bowl. Cream them until smooth and well combined, scraping the sides of the bowl as needed so no pockets of butter or sugar remain.
Step 3: Beat in the first egg until the mixture looks smooth, then add the second egg and mix again. Stir in the vanilla extract, taking care not to overbeat the mixture once the eggs are fully incorporated.
Step 4: In a separate bowl, whisk the all-purpose flour, baking soda, and salt together. This distributes the baking soda and salt evenly, which helps prevent a salty bite or uneven rise in the finished bars.
Step 5: Gradually add the dry ingredients to the butter mixture. Mix only until the flour disappears, because excessive mixing can make the bars firmer and less tender.
Step 6: Fold in the semisweet chocolate chips with a sturdy spatula or wooden spoon. Stop as soon as the chips are evenly dispersed so the dough remains soft and cohesive.
Step 7: Transfer the dough to the prepared pan and press it into an even layer. The dough is thick, so lightly greased fingertips or the flat side of a spoon can make it easier to reach the corners without tearing the parchment.
Step 8: Bake for 25 to 30 minutes, checking near the lower end of the range. The edges should be lightly browned, while the center should look set but still slightly soft; this is the best point to remove the pan for chewy results.
Step 9: Place the pan on a cooling rack and let the bars cool for at least 30 minutes before slicing. The residual heat will finish setting the center, and the cooling time allows cleaner cuts with fewer crumbling edges.
Pro Tips for Soft, Chewy Bars
Flour measurement is one of the most important details in this recipe. The most reliable method is to weigh out 270 grams, but if you use cups, spoon the flour lightly into the measuring cup and level the top rather than scooping directly from the bag.
Softened butter should be pliable but not melted or oily. If the butter is too warm, the dough may become loose and the bars can spread more than expected; if it is too cold, the sugar will not cream into a smooth mixture.
Keep an eye on the center during baking. A fully firm center in the oven often means the bars will be dry once they cool, so take them out when the edges show color and the middle retains a slight softness.
- Use a light-colored metal pan for a moderate, even bake when possible.
- Begin checking at 25 minutes because pan material and oven calibration can affect the result.
- Allow the bars to cool before cutting so the chocolate and crumb can set.
- For tidy squares, use a sharp knife and wipe the blade between cuts.

Serving, Cutting, and Storage
Once cooled, cut the slab into 24 bars for a classic party-sized portion, or make larger squares when serving them as a plated dessert. They are delicious at room temperature, but a few seconds of gentle warming can soften the chocolate chips and make the centers taste freshly baked.
Serve the bars with cold milk, coffee, vanilla ice cream, or a scoop of chocolate ice cream. For a dessert plate, add a light dusting of powdered sugar only after the bars have cooled completely, though they are flavorful enough to serve plain.
Store the cooled cookies in an airtight container at room temperature. Place parchment between layers if stacking them, and enjoy them within several days for the best chewy texture.
These bars also travel well because their sturdy edges help them hold together. Let them cool fully before packing, and avoid sealing them while warm because trapped steam can make the surface sticky.
Easy Variations and Pairings
The classic semisweet chocolate chip version is balanced and familiar, but the base recipe is flexible. You can serve the bars as written or make small presentation changes without altering the measured dough.
- Cut the cooled slab into smaller bites for a cookie buffet or lunchbox treat.
- Serve warm bars with ice cream for a simple skillet-cookie-style dessert.
- Pair a square with espresso or black tea to balance its buttery sweetness.
- Create a mixed dessert tray with classic bars and chewy ginger cookies for contrasting spice and chocolate flavors.
For a celebration, arrange the bars on a platter with the chocolate chips facing upward and cut each piece evenly. If you are building a larger dessert spread, our chocolate chip cake is another approachable choice with the same beloved chocolate-chip appeal.

Ingredients
Method
- Heat the oven to 350°F (175°C). Grease a 13-by-9-inch baking pan or line it with parchment, leaving enough parchment overhang to help lift the cooled bars from the pan.
- Cream the softened butter, packed light brown sugar, and granulated sugar until smooth and well combined. The mixture should look creamy and evenly blended rather than lumpy.
- Beat in the eggs one at a time, mixing after each addition. Add the vanilla extract and stir until incorporated.
- In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. Gradually add the dry mixture to the butter mixture, mixing only until no dry streaks remain.
- Stir in the semisweet chocolate chips until they are distributed throughout the dough. Avoid overmixing once the flour has been added.
- Press the dough evenly into the prepared 13-by-9-inch pan. Use lightly greased fingertips or the back of a spoon to help spread the thick dough into the corners.
- Bake for 25 to 30 minutes, until the edges are lightly browned and the center is set but still slightly soft. Do not wait for the center to look completely firm or the finished bars may lose their chewy texture.
- Cool the pan on a rack for at least 30 minutes before cutting. Slice into squares once the bars have firmed, using the parchment overhang to lift them out if desired.
Notes
Final Thoughts
Chewy chocolate chip bar cookies are one of the easiest ways to turn a familiar cookie recipe into a generous pan dessert. The dough comes together in one main bowl, bakes in 25 to 30 minutes, and cools into soft, buttery squares with lightly browned edges and a chocolate-filled center.
For the best result, measure the flour carefully, mix only until the ingredients are combined, and resist the urge to bake until the middle looks completely firm. That slightly soft center is what helps these bars remain chewy after they finish cooling.
Make them for bake sales, after-school snacks, potlucks, holiday cookie trays, or an uncomplicated weekend dessert. Once you taste the rich brown sugar flavor and melty semisweet chocolate, this dependable 13-by-9-inch pan recipe is likely to become a regular in your baking rotation.
