Whether you serve them warm with a scoop of ice cream or enjoy them at room temperature with a glass of milk, these cookie bars are guaranteed to satisfy your sweet tooth.

Why You’ll Love These Cookie Bars

Before diving into the recipe, let’s take a closer look at what makes these bars a standout treat.

1. Effortless Preparation – Unlike individual cookies that require scooping and multiple baking sheets, cookie bars are baked in a single pan, which means less work and less cleanup.
2. Soft, Chewy Perfection – The combination of melted butter and brown sugar creates a soft, dense texture with a subtle caramel note that keeps every bite moist.
3. Customizable Goodness – While semi-sweet chocolate chips are a classic choice, you can easily adapt this recipe by adding nuts, white chocolate, or even a swirl of caramel or peanut butter.
4. Ideal for Sharing – One batch yields a generous pan of bars that can be sliced into squares or rectangles, making them perfect for parties, potlucks, or bake sales.

Key Ingredients and Their Roles

Understanding the purpose of each ingredient will help you master this recipe and give you the confidence to tweak it to your taste.

• Unsalted Butter (1 cup / 226g)
  Using melted butter instead of creamed butter creates a denser, chewier texture—exactly what you want in a cookie bar. Unsalted butter gives you control over the saltiness of the final product.
• Light Brown Sugar (1 cup / 200g)
  Brown sugar is the secret to soft, moist cookie bars. Its molasses content adds a subtle caramel flavor and helps retain moisture.
• Granulated Sugar (½ cup / 100g)
  A small amount of white sugar balances the sweetness and provides structure, giving the bars just the right amount of lift.
• Eggs (2 large)
  Eggs bind the ingredients and contribute richness, helping the bars set while staying tender.
• Vanilla Extract (2 teaspoons)
  Vanilla enhances the overall flavor, adding warmth and depth.
• All-Purpose Flour (2¼ cups / 280g)
  This is the backbone of the recipe, providing structure and chewiness. Measure carefully to avoid a dry or crumbly texture.
• Salt (½ teaspoon)
  Salt balances the sweetness and enhances the flavors of both the dough and the chocolate.
• Baking Soda (½ teaspoon)
  A small amount of baking soda provides a gentle lift, keeping the bars soft without making them cakey.
• Semi-Sweet Chocolate Chips (2 cups / 340g)
  The star of the show. Semi-sweet chips offer the perfect balance of sweetness and richness, creating melty pockets of chocolate in every bite.

Equipment You’ll Need

You don’t need any fancy gadgets to make these cookie bars, just a few kitchen basics:

• A 9×13-inch baking pan for even baking and easy slicing.
• Mixing bowls—one large for the dough, one small for dry ingredients.
• A whisk and a rubber spatula or wooden spoon for mixing.
• Parchment paper for lining the pan to prevent sticking and to lift the bars out easily.

Step-by-Step Method

Follow these simple steps to create the perfect Melt-in-Your-Mouth Chocolate Chip Cookie Bars.

Step 1: Prepare the Pan and Preheat the Oven

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving an overhang on two sides for easy removal later. Lightly grease the parchment with nonstick spray or butter to ensure the bars release effortlessly.

Step 2: Combine the Wet Ingredients

In a large mixing bowl, whisk together the melted and slightly cooled butter, light brown sugar, and granulated sugar until smooth and well combined. This step dissolves the sugars and creates a shiny, caramel-like base for the dough.

Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract until the mixture is creamy and uniform.

Step 3: Mix the Dry Ingredients

In a separate bowl, whisk together the flour, salt, and baking soda. This ensures the leavening agent and salt are evenly distributed.

Step 4: Combine Wet and Dry

Gradually add the dry ingredients to the wet mixture, stirring gently with a rubber spatula until no streaks of flour remain. Be careful not to overmix, as this can lead to tough bars.

Step 5: Fold in the Chocolate Chips

Reserve a small handful of chocolate chips for topping. Fold the remaining chips into the dough, ensuring they are evenly dispersed.

Step 6: Spread and Bake

Spread the dough evenly into the prepared pan, smoothing the top with a spatula. Sprinkle the reserved chocolate chips over the surface for a bakery-style finish.

Bake for 25–30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out with a few moist crumbs. Avoid overbaking—the bars will continue to firm up as they cool.

Step 7: Cool and Slice

Allow the bars to cool in the pan for at least 30 minutes before lifting them out using the parchment overhang. Transfer to a cutting board and slice into squares or rectangles. For clean edges, use a sharp knife wiped clean between cuts.

Tips for Perfect Cookie Bars

• Don’t Skip Cooling: Cutting too soon can cause the bars to crumble. Cooling allows the butter and sugars to set for neat slices.
• Adjust for Altitude: If you live at a high altitude, slightly reduce the baking soda to prevent excessive rising.
• Make Them Your Own: Add chopped walnuts, pecans, or white chocolate chips for a fun twist. A drizzle of melted chocolate after baking also makes for an elegant presentation.

Storage and Make-Ahead Options

One of the best things about these cookie bars is how well they keep.

• Room Temperature: Store in an airtight container for up to 5 days.
• Refrigeration: Keep in the fridge for up to 1 week. Bring to room temperature or microwave for a few seconds before serving for that just-baked taste.
• Freezing: Wrap individual bars in plastic wrap and freeze for up to 3 months. Thaw at room temperature or reheat gently in the microwave.

Serving Suggestions

These cookie bars are delicious on their own, but you can elevate them with a few serving ideas:

• A la Mode: Serve warm bars with a scoop of vanilla ice cream and a drizzle of chocolate syrup for an indulgent dessert.
• Coffee Companion: Pair with a cappuccino or latte for a sweet afternoon treat.
• Holiday Touch: Add a sprinkle of flaky sea salt on top before baking for a festive, gourmet finish.

Frequently Asked Questions

1. Can I use salted butter instead of unsalted?
Yes, but reduce the added salt to a pinch to avoid over-salting the dough.

2. Can I substitute the chocolate chips with other mix-ins?
Absolutely! White chocolate, butterscotch chips, peanut butter chips, or even chopped candy bars make excellent additions.

3. What if I don’t have light brown sugar?
You can use dark brown sugar for a deeper molasses flavor. If you only have granulated sugar, add 1 teaspoon of molasses to mimic the richness of brown sugar.

4. Can I halve the recipe?
Yes, simply bake in an 8×8-inch pan and reduce the baking time to about 20–25 minutes.

5. How do I know when the bars are done?
The edges should be golden, and the center should look slightly underbaked. A toothpick inserted in the middle should come out with a few moist crumbs.

6. Can I make the dough ahead of time?
Yes, prepare the dough up to 24 hours in advance. Store it covered in the refrigerator, then let it come to room temperature before baking.

7. How can I make these bars extra gooey?
For extra gooeyness, reduce the baking time by a couple of minutes and enjoy while slightly warm.
