Ingredients for Gooey Chocolate Chip Cookie Bars (Makes 16 bars)

Dry Ingredients

2 ¼ cups all-purpose flour
1 teaspoon baking soda
½ teaspoon salt

Wet Ingredients

¾ cup unsalted butter, melted
1 cup brown sugar (light or dark)
½ cup granulated sugar
2 large eggs
1 tablespoon vanilla extract

Mix-Ins

1 ½ cups semi-sweet chocolate chips
½ cup chocolate chunks (optional but recommended)
Optional: ½ cup chopped walnuts or pecans

For Topping

Extra chocolate chips or chunks
A pinch of flaky sea salt (optional)

Instructions: How to Make Gooey Chocolate Chip Cookie Bars

STEP 1 — Prepare the Pan

Preheat your oven to 350°F (175°C).
Line an 8×8-inch or 9×9-inch baking pan with parchment paper.
Leave an overhang for easy lifting.

A smaller pan = thicker, gooier bars.
A larger pan = thinner, slightly crispier bars.

STEP 2 — Prepare the Dry Ingredients

In a bowl, whisk together:

flour
baking soda
salt

Set aside.

STEP 3 — Mix the Wet Ingredients

In a large bowl, whisk together:

melted butter
brown sugar
granulated sugar

Whisk until creamy and smooth.

Add the eggs and vanilla extract.
Whisk again until everything is combined.

STEP 4 — Combine the Dry and Wet Ingredients

Add the dry mixture to the wet mixture.
Mix gently with a spatula until no streaks of flour remain.
Do not overmix.

STEP 5 — Fold in the Chocolate

Add:

chocolate chips
chocolate chunks
nuts (optional)

Fold gently to keep the dough thick and gooey.

STEP 6 — Spread the Dough Into the Pan

Spoon the thick cookie dough into your prepared pan.
Press it evenly with a spatula or your hands.

Sprinkle extra chocolate chips or chunks on top for a bakery-style look.

STEP 7 — Bake

Bake for:

25–30 minutes for gooey bars
30–35 minutes for firmer bars

The top should be golden, the center slightly soft, and the edges lightly browned.

TIP: Do not overbake—the secret to gooey bars is taking them out slightly underdone.

STEP 8 — Cool & Slice

Let the bars cool completely before cutting.
This helps them set and stay beautifully thick and gooey.

Slice into squares and enjoy!

Tips for the Perfect Gooey Cookie Bars

1. Use melted butter instead of softened

Melted butter equals a richer, chewier bar.

2. Don’t overmix

Overmixing creates tough cookie bars. Mix only until combined.

3. Underdone = gooey

The center should look slightly soft when you remove the pan from the oven.

4. Use brown sugar for moisture

Brown sugar adds:

moisture
chewiness
caramel flavor

Dark brown sugar deepens flavor even more.

5. Add chocolate chunks

They melt into big puddles of chocolate—pure heaven.

6. Chill before slicing for cleaner cuts

If you want sharp, bakery-style squares, refrigerate before slicing.

7. Add sea salt

A pinch of flaky salt makes the flavors pop.

8. Want thicker bars?

Use an 8×8″ pan and bake slightly longer.

Serving Suggestions

These bars are amazing as-is, but you can elevate them easily:

Serve warm with vanilla ice cream
Drizzle with caramel sauce
Dip into cold milk
Top with whipped cream
Serve with chocolate or espresso drizzle

For parties, cut into bite-sized squares and serve on a dessert board.

Variations: Fun and Creative Ways to Transform Your Bars

1. Triple Chocolate Bars

Use a mix of:

milk chocolate
dark chocolate
white chocolate

2. Peanut Butter Swirl Cookie Bars

3. Nutella Cookie Bars

Drop spoonfuls of Nutella into the dough and marble it.

4. S’mores Cookie Bars
