Chewy Chocolate Chip Cookie Bars Recipe — Crowd-Pleasing Dessert

Tender, gooey, and loaded with chocolate, these cookie bars are irresistibly good. I made them twice last week because they disappear fast — they’re that addictive.

Soft, buttery cookie bars are what I call “sweatpants cookies”: comforting, easy, and ideal when you want something cozy and indulgent without fuss. Bars deliver the same chewy texture you love in chocolate chip cookies without chilling, rolling, or baking multiple batches.

The Best-Ever Chocolate Chip Cookie Bars, at a Glance

• One bowl. Make the dough in a single bowl, spread it into a pan, and bake — no mixer required if you prefer.
• Easy to make. No chilling or rolling the dough, and no worrying about cookies spreading while they bake.
• Crowd-pleasing. These soft-baked bars please lovers of both gooey centers and crisp edges.

Ingredients You’ll Need

Here are quick notes on the pantry staples for these chewy chocolate chip cookie bars. For exact measurements, see the recipe card below.

• Flour – Measure with the spoon-and-level method to avoid overpacking, which can make bars dry.
• Baking soda – Use baking soda (not baking powder) and check the package date to ensure it’s active.
• Sugar – A mix of white and brown sugar adds moisture and depth. Use all of one kind if needed.
• Eggs and butter – Room temperature eggs and butter mix more evenly. Salted butter works fine, or use unsalted if preferred.
• Chocolate – Chocolate chunks or chopped chocolate create melty pockets throughout the bars.

How to Make Chocolate Chip Cookie Bars

These bars bake in a 9×13-inch pan and slice into squares for sharing or freezing. You can mix the dough by hand or with a mixer.

• Mix the dough. Cream butter with both sugars, then beat in eggs, vanilla, baking soda, and a pinch of salt. Add the flour gradually and fold in the chocolate chunks.

• Bake. Press the dough evenly into a greased 9×13-inch pan. Bake at 350°F for 30–35 minutes until the center is just set and the edges are golden brown. Avoid overbaking so the bars remain tender.
• Cool. Let the bars cool completely in the pan before slicing for clean squares.

Baking Notes

• Don’t overmix. Once the flour is added, mix only until combined to avoid dense, flat bars.
• Check doneness. The bars should be just set in the center; they will finish setting as they cool from residual heat. Overbaked bars become dry and crumbly.
• Line the pan for easy removal. Greasing the pan is usually enough, but lining it with parchment that overhangs the sides lets you lift the bars out for effortless slicing.
• Cool before serving. For neat slices and the best texture, cool the bars completely to room temperature before cutting.
• Optional salt finish. Sprinkle coarse or flaky sea salt over the bars as they come out of the oven to add a pleasant sweet-salty contrast.

Pro Tip: Brown Butter Option

Browning the butter before adding it to the dough adds a deep, nutty flavor. If you want richer, more complex flavor, brown the butter, cool it slightly, then proceed with the recipe.

Storage and Freezing

• Store airtight. Keep the bars in an airtight container at room temperature for up to 3 days for best freshness.
• Freeze. Cut the bars before freezing. Separate stacked layers with parchment and store in an airtight container or freezer bag for up to 2 months. Thaw at room temperature before serving.
