Easy Gooey Chocolate Chip Cookie Bars – Soft Chewy Cookie Bar Recipe

Byluca Carter April 3, 2026April 3, 2026

Introduction

There is something incredibly comforting about a pan of warm Gooey Chocolate Chip Cookie Bars fresh from the oven. These soft, chewy bars capture all the joy of classic chocolate chip cookies with less effort, making them perfect for family treats, gatherings, or cozy nights at home.

The image shows a stack of three thick, square-shaped chocolate chip cookie bars on a white marbled surface. Each bar has a golden-brown, slightly crispy top layer with melted dark brown chocolate chips unevenly spread on and inside it, showing gooey textures. The middle layer appears soft and chewy with visible chunks of chocolate, while the bottom layer is dense and slightly darker brown, supporting the rest. The edges of the bars are browned and slightly crumbly. Additional chocolate chip cookie bars and loose chocolate chips are blurred in the background. photo taken with an iphone --ar 4:5 --v 7

Ingredients

1 cup unsalted butter, melted and slightly cooled
1 1/4 cups packed light brown sugar

1/2 cup granulated sugar
2 large eggs, room temperature

2 teaspoons pure vanilla extract
2 1/2 cups all-purpose flour

1 teaspoon cornstarch
1 teaspoon baking soda
1/2 teaspoon baking powder

1 teaspoon fine salt
2 cups semi-sweet chocolate chips
1/2 cup chocolate chunks, for extra gooey pockets on top

1 tablespoon flaky sea salt, optional for finishing

Instructions

Step 1: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on the sides to lift the bars out easily. Lightly grease the parchment and any exposed pan edges.
Step 2: In a large bowl, whisk together the melted butter, light brown sugar, and granulated sugar until smooth and glossy. Add the eggs and vanilla extract, then whisk until fully combined and slightly thickened.

Step 3: In a separate bowl, whisk the flour, cornstarch, baking soda, baking powder, and salt to evenly distribute the leavening agents.
Step 4: Gradually add the dry ingredients to the wet ingredients and stir gently until just combined. Fold in the semi-sweet chocolate chips without overmixing.
Step 5: Transfer the dough to the prepared pan and press it into an even layer. Sprinkle the chocolate chunks evenly on top, gently pressing some into the surface. Add flaky sea salt if desired.

Step 6: Bake for 24 to 30 minutes, until the edges are golden brown and the center looks just set. For gooier bars, aim for the shorter baking time and allow the residual heat to finish setting.
Step 7: Let the bars cool completely in the pan before slicing for clean edges. To serve warm, cool for 30 to 45 minutes and cut while slightly warm. Use the parchment overhang to lift the bars out of the pan.

Tips & Variations

Use room-temperature eggs and melted but cooled butter for the best texture.

Measure flour by spooning it into the cup and leveling it off to avoid dry bars.
Avoid overmixing after adding flour to keep the bars tender, not tough.
Swap 1/2 cup semi-sweet chips for dark chocolate chunks or add 1/2 cup chopped toasted nuts for extra flavor and texture.

Top with mini chocolate chips before baking for a more bakery-style finish.
Serve warm with vanilla ice cream or a drizzle of chocolate sauce for a special treat.

Storage

Store completely cooled bars in an airtight container at room temperature for up to 4 days, separating layers with parchment paper. For longer storage, refrigerate up to 1 week or freeze individually wrapped bars for up to 2 months. Thaw at room temperature or warm briefly in the microwave before serving.

How to Serve

A stack of three square chocolate chip cookie bars is shown on a white marbled surface. Each bar has a light golden-brown top layer filled with semi-melted dark chocolate chips that create small glossy pockets across the surface. The middle layer reveals a rich, dense chocolate interior mixed with a soft, moist cookie dough texture in light brown with darker chocolate chunks embedded throughout. Around the stack, additional cookie bars are scattered, with a few loose chocolate chips on the surface. The bars have a slightly crumbly texture on the edges and appear thick and chewy. photo taken with an iphone --ar 4:5 --v 7

FAQs

Why did my chocolate chip cookie bars turn out dry instead of gooey?

Dry bars often result from too much flour, overmixing, or overbaking. Measure flour by spooning it into your cup and leveling it off to avoid packing in extra flour. Stir only until combined to prevent developing too much gluten, and remove the bars when the edges are golden but the center still looks slightly soft to keep them gooey.

Can I make these cookie bars ahead of time?

Yes, these bars taste even better the next day as the flavors meld and the texture becomes chewier. Bake in advance, cool completely, and store covered at room temperature. You can also freeze sliced bars and thaw before serving. Warming bars briefly before serving recreates that fresh-baked softness.

Can I use a different size pan for this recipe?

A 9×13-inch pan is ideal for soft centers and chewy edges. Using a smaller pan will make thicker bars that may need longer baking, while a larger pan will thin them out and bake faster, which can reduce gooeyness. If using an 8×8 or 9×9-inch pan, consider halving the recipe for best results.

What kind of chocolate works best in cookie bars?

Semi-sweet chocolate chips balance sweetness and richness perfectly, melting well while holding shape. You can customize with dark chocolate chunks for deeper flavor, milk chocolate for creaminess, or a mix of chocolate chips and chunks for varied texture and melted pockets.
