This easy chocolate chip cookie bars recipe makes soft, chewy cookie bars in a 9 x 13-inch pan with simple pantry ingredients. The buttery dough comes together in about 10 to 15 minutes, then bakes at 350°F (175°C) for 22 to 28 minutes, making this a practical dessert for parties, bake sales, lunch boxes, or an everyday sweet treat.
Each bar has golden edges, a tender center, and plenty of melty semisweet chocolate chips in every bite. Let the bars cool completely before slicing for neat squares, or enjoy one slightly warm when the chocolate is still soft and fragrant.

Cookie bars offer all the flavor of classic chocolate chip cookies with much less shaping and preparation. Instead of portioning dough onto multiple baking sheets, you press the entire batch into one pan and bake it together.
The texture is the best part: the edges become lightly crisp and golden, while the center stays soft, chewy, and rich. Brown sugar gives the bars a warm caramel note, and vanilla rounds out the buttery dough.
This recipe is also flexible enough for casual baking. Serve the bars plain, add walnuts or pecans for crunch, or finish them with a tiny sprinkle of flaky sea salt to balance the sweetness.

Ingredients You’ll Need
The recipe starts with 1 cup, or 226 grams, of softened unsalted butter. Soft butter blends smoothly with the sugars and helps create a creamy base, so allow it to soften at room temperature rather than melting it.
You will use 3/4 cup each of granulated sugar and packed light brown sugar. The granulated sugar supports lightly crisp edges, while the brown sugar adds moisture, color, and a gentle molasses flavor.
Two room-temperature eggs help the batter mix evenly, and 2 teaspoons of vanilla extract add familiar chocolate chip cookie flavor. For the dry ingredients, use 2 1/4 cups, or 281 grams, of all-purpose flour, 1 teaspoon baking soda, and 1/2 teaspoon table salt.
Two cups, or 340 grams, of semisweet chocolate chips create generous chocolate pockets throughout the bars. Chopped walnuts or pecans are optional, and flaky sea salt can be added after baking.
- Use softened butter, not hot melted butter, for the stated texture.
- Pack the brown sugar firmly into the measuring cup.
- Measure flour by weight when possible.
- If measuring flour by cups, spoon it into the cup and level the top.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C). Line a 9 x 13-inch pan with parchment paper, leaving enough overhang on two sides to lift out the cooled bars, then lightly grease the pan if the parchment does not fully cover the surface.
Step 2: Whisk the all-purpose flour, baking soda, and table salt in a medium bowl. Mixing these ingredients first distributes the baking soda and salt evenly before they reach the wet ingredients.
Step 3: Place the softened butter, granulated sugar, and packed light brown sugar in a large bowl. Beat for about 2 minutes, until the mixture looks smooth and creamy with no large streaks of butter.
Step 4: Add the eggs one at a time, beating after each addition so the first egg is incorporated before adding the second. Mix in the vanilla extract until the batter is uniform and fragrant.
Step 5: Add the whisked dry ingredients to the butter mixture. Mix only until the flour disappears; stopping promptly keeps the finished cookie bars tender rather than tough.
Step 6: Fold in the semisweet chocolate chips with a sturdy spatula. If using nuts, fold in the chopped walnuts or pecans at the same time, taking care not to crush the chips.
Step 7: Transfer the thick dough to the prepared pan and press it into an even layer. A lightly greased spatula or slightly damp fingertips make this step easier and help the corners fill without sticking.
Step 8: Bake for 22 to 28 minutes. Look for golden-brown edges and a center that appears set but still slightly soft; the middle will continue cooking from the residual heat after the pan leaves the oven.
Step 9: Cool the pan for at least 30 minutes, or until the bars are fully cool, before lifting them out and slicing. Add flaky sea salt after baking if you like a sweet-salty finish, then cut into squares or bars.
Pro Tips for Soft, Chewy Bars
The most important visual cue is the center. Do not wait for the entire surface to become dark brown, because that usually means the bars have baked too long and may lose their soft texture.
Butter should be softened enough to press easily with a fingertip but should not look oily or melted. If the butter is too warm, the dough can become difficult to spread and the finished bars may bake differently than intended.
Do not overmix after adding the flour. A few final folds are preferable to prolonged beating, and it is fine to stop as soon as no dry patches remain.
Parchment makes a noticeable difference when working with cookie bars. The overhang lets you lift the cooled slab in one piece, which makes cutting cleaner and reduces the chance of scraping bars from the pan.
For particularly tidy squares, use a sharp knife and wipe the blade between cuts. If you prefer softer, more rustic portions, cut the slab while it is just barely warm, but wait until it has cooled enough to hold together.

Easy Variations and Serving Ideas
Walnuts and pecans both work well in this dough. Walnuts provide a slightly earthy crunch, while pecans taste especially buttery and pair beautifully with the brown sugar.
You can keep the bars simple with semisweet chips alone, or add the optional nuts for more contrast. A light sprinkle of flaky sea salt after baking adds texture without changing the basic recipe.
Serve the bars at room temperature for a soft, chewy bite. For a more indulgent dessert, warm a square briefly and serve it with vanilla ice cream, whipped cream, or a drizzle of chocolate sauce.
These bars also fit nicely on a mixed dessert table. Pair them with a colorful chocolate coconut almond poke cake for a celebration where guests can choose between cookie texture and tender cake.
Storage and Make-Ahead Advice
Cool the bars completely before storing them. Place them in an airtight container at room temperature, separating layers with parchment if you stack them, and enjoy them within several days for the best texture.
If you prefer to prepare them ahead, bake the bars, cool them fully, and keep the slab uncut until serving. The uncut slab retains moisture well and can be sliced shortly before guests arrive.
For a warm serving texture, reheat an individual bar briefly until the chocolate softens. Let it stand for a moment before eating, since the center can become very hot.

Choosing the Right Pan
A 9 x 13-inch pan gives you a generous batch of moderately thick cookie bars and is the pan size used for the timing in this recipe. Keep the dough level from corner to corner so the edges and center bake as evenly as possible.
For thicker bars, use an 8 x 8-inch pan and bake for approximately 25 to 32 minutes. Because the dough is deeper, the center will remain softer and the bars will be taller than those baked in the larger pan.
Whichever pan you choose, rely on the color and texture cues rather than baking until the whole surface is dark. Golden edges and a slightly soft center are what produce the most appealing chewy result.
