Chocolate Chip Cookie Bars

Chocolate Chip Cookie Bars

Introduction
These Chocolate Chip Cookie Bars take everything you love about a classic cookie and turn it into a thick, chewy traybake that is perfect for sharing. Expect a golden, slightly crisp top and a tender, soft interior with pockets of melted semi-sweet chocolate in every bite. The aroma is warm and buttery with caramel notes from the brown sugar, and the texture balances chewiness and light crumb thanks to the cornstarch and the extra yolk. These bars are ideal for potlucks, school lunches, an after-school treat, or a simple weeknight dessert when you want cookie satisfaction without portioning dozens of individual cookies. If you love traditional cookies, try this bar version for an easy bake that slices beautifully and stores well.

Ingredients

• 2 and 1/4 cups all-purpose flour, measured and leveled, provides structure and body to the bars.
• 1 teaspoon baking soda, gives lift and helps create a light crumb.
• 1 and 1/2 teaspoons cornstarch, keeps the centers tender and slightly cakey for chewiness.
• 1/2 teaspoon salt, balances sweetness and enhances flavor.
• 3/4 cup unsalted butter, melted and slightly cooled, adds rich butter flavor and chew.
• 1 cup packed light brown sugar, brings moisture and a deep, molasses-like sweetness.
• 1/3 cup granulated sugar, contributes crisping and sweetness contrast.
• 1 large egg, at room temperature, helps bind and leavens slightly.
• 1 large egg yolk, at room temperature, adds extra richness and chew.
• 2 teaspoons pure vanilla extract, heightens overall flavor with warm aromatics.
• 1 cup semi-sweet chocolate chips, fold in for melty chocolate pockets.
• Optional: sprinkle of flaky sea salt, finish for contrast and a gourmet touch.

Step-by-step Instructions

1. Preheat and prepare the pan. Preheat the oven to 350°F (177°C). Line a 9-inch square baking pan with parchment paper, allowing the parchment to hang over two opposite sides for easy lifting later.
2. Mix the dry ingredients. In a large bowl, whisk together the flour, baking soda, cornstarch, and salt until evenly combined.
3. Combine the melted butter and sugars. In a medium bowl, whisk the melted, slightly cooled butter, brown sugar, and granulated sugar until the mixture is smooth and uniform.
4. Add the eggs and vanilla. Whisk the large egg, egg yolk, and vanilla extract into the sugar and butter mixture until blended.
5. Bring wet and dry together. Add the wet mixture to the dry ingredients and stir until just incorporated. Do not overmix to keep the bars tender.
6. Fold in the chocolate chips. Gently fold the 1 cup of semi-sweet chocolate chips into the dough so they are evenly distributed.
7. Press into the pan. Transfer the dough to the prepared baking pan and press it into an even layer with a spatula or your fingertips. If using, sprinkle flaky sea salt over the top for contrast.
8. Bake. Bake for 30 to 34 minutes, until the top is lightly browned and a toothpick inserted into the center comes out mostly clean with a few moist crumbs.
9. Cool and cut. Allow the bars to cool in the pan for at least an hour before lifting them out using the parchment overhang and cutting into squares. If you prefer a single large cookie instead of bars, see this giant cookie version for inspiration.

Tips, Storage & Variations
Tips

• Measure flour by spooning it into the cup and leveling to avoid dense bars.
• Use room temperature eggs to help the batter come together smoothly.
• If the edges brown faster than the center, tent the pan with foil for the last 5 minutes.

Storage

• At room temperature: Store cooled bars in an airtight container for up to 3 days.
• Refrigeration: Keep bars in an airtight container in the fridge for up to 1 week.
• Freezing: Wrap individual squares tightly in plastic wrap and place in a freezer bag for up to 3 months. Thaw at room temperature or warm briefly in a low oven.

Variations using only the ingredients listed

• Extra chocolate pockets: Stir in more chocolate chips from the listed 1 cup amount by folding a few extra chips on top before baking.
• Salted top: Finish with a more generous sprinkle of flaky sea salt for a sweet and salty contrast.
• Richer chew: Make sure to include the extra egg yolk as written for maximum chewiness and tenderness.
• Nutty idea without adding ingredients: Serve bars alongside a nut-forward dessert like a chocolate chip pecan version to mimic textural contrast without changing this recipe.

FAQ

1. How do I know when the bars are done?
   The top should be lightly browned and a toothpick inserted in the center should come out mostly clean with a few moist crumbs attached.
2. Can I use salted butter instead of unsalted?
   Yes, but reduce additional salt slightly if you prefer less overall saltiness.
3. Why is cornstarch included?
   Cornstarch keeps the centers tender and contributes to a chewier texture.
4. Can I make these ahead of time?
   Yes, bake and cool, then store at room temperature for up to 3 days or freeze for longer storage.
5. How should I cut the bars neatly?
   Chill the bars for an hour, then use a sharp knife wiped between cuts for clean edges.
6. Are these bars suitable for school lunches?
   Yes, they are portable and slice neatly, making them a good option for packed lunches.

People Also Ask

1. Can I bake this recipe in a different sized pan?
   A 9-inch square is recommended to match baking time and texture. Larger pans will yield thinner bars and may need less time.
2. What does adding an extra egg yolk do?
   The extra yolk adds fat and richness, creating a chewier, more tender center.
3. Can I use dark chocolate instead of semi-sweet chips?
   Yes, but the recipe already specifies semi-sweet chips. Substituting darker chips will change sweetness and flavor.
4. Is it better to melt the butter for bars?
   Melted butter gives a denser, chewier texture, which is desirable for these cookie bars.
5. How can I prevent the edges from overbrowning?
   If edges brown too quickly, loosely tent the pan with foil toward the end of baking.
6. Should I cool the bars completely before cutting?
   Cooling at least an hour in the pan helps them set and makes cutting cleaner.
7. Can I double the recipe?
   Doubling is possible, but use a larger pan and monitor baking time closely.
8. Will these bars firm up as they cool?
   Yes, they will firm up as they cool and set, making them easier to slice.
