Ingredients Breakdown & Prep Tips

- 1/2 teaspoon salt — Balances the sweetness beautifully.
- 3/4 cup (12 Tbsp; 170g) unsalted butter, melted and slightly cooled — Essential for rich flavor and texture.
- 1 cup (200g) packed light brown sugar — Adds a hint of caramel flavor that’s irresistible.
- 1/3 cup (67g) granulated sugar — Creates a delightful sweetness.
- 1 large egg plus 1 large egg yolk, at room temperature — Gives the bars that perfect gooey center.
- 2 teaspoons pure vanilla extract — Infuses warmth and depth of flavor.
- 1 cup (180g) semi-sweet chocolate chips — The star of the show!
- Optional: sprinkle of flaky sea salt — For that gourmet touch!
Now that you have your ingredients ready, let’s begin the delightful process of baking these bars!
Prep Method with Sensory Cues
Preheat your oven to 350°F (177°C). As the oven warms, line a 9-inch square baking pan with parchment paper—leave a little extra hanging over the sides, oh so helpful for lifting the cooled bars out.
In a large bowl, whisk together your flour, baking soda, cornstarch, and salt until they’re well combined, filling your kitchen with a faintly sweet, floury scent. Meanwhile, in a medium bowl, combine the melted butter, light brown sugar, and granulated sugar until there are no lumps. The butter mixes glossy against the sugars, creating a smooth, thick mixture. Add in your egg, extra egg yolk, and that irresistible vanilla extract, stirring until it’s thick like a dreamy batter.
Now for the fun part! Pour those wet ingredients into the dry mixture and combine them until just incorporated. The dough glistens softly, thick yet supple—fold in those rich chocolate chips, ensuring they’re evenly distributed. You might notice they don’t stick as well due to the melted butter, but don’t fret; they’ll do their magic during baking!
Transfer this delicious dough to your prepared pan, pressing it into an even layer. If desired, lightly sprinkle the top with flaky sea salt—trust me, it enhances every bite! For added charm, press a few additional chocolate chips into the top.
Bake for 30-34 minutes until the edges turn a beautiful golden brown, but don’t let your excitement lead to over-baking. A toothpick inserted should come out mostly clean—a little bit of softness in the center is just perfect.
Let the bars cool in the pan on a wire rack for a solid hour. Once they’ve cooled and become firm, lift them out using the parchment and cut them into generous squares. And there they are—classic cookie bars, waiting to be devoured!
Avoid These Mistakes
Baking success can sometimes come with a learning curve. Here are some common mistakes when making Classic Chocolate Chip Cookie Bars, along with comforting solutions:
- Over-baking — This can lead to dry bars. Remember, slightly under-baked is better—those chocolate chips will continue to melt even after removing them from the oven.
- Chocolate Chips Not Sticking — If your chocolate chips seem to slip away in dough, that’s alright! Just fold them in gently before baking.
- Not Measuring Flour Accurately — Spoon and level, friends! Packing in flour can lead to heavy, dry bars instead of the light, chewy ones we adore.
Pro Tips to Get It Right
- Ensure eggs are at room temperature; they’ll blend in better with your melted butter, creating a harmonious batter.
- Allow your baked bars to cool in the pan for an hour; this allows them to set perfectly without crumbling.
Best Ways to Serve It
These Classic Chocolate Chip Cookie Bars shine in a range of scenarios—perfect for a cozy family dinner, a heartfelt treat during movie night, or even as dessert at a summer picnic with friends. Serve them warm with a scoop of vanilla ice cream for that heavenly combination!
Storage + Seasonal or Dietary Variations
Once you’re done indulging, any leftover bars can be stored at room temperature in an airtight container for up to a week (if they last that long!). You can also freeze them, wrapped tightly, for a rainy day craving; simply thaw them at room temperature or give them a quick zap in the microwave. Want to mix things up? Try adding nuts, or even butterscotch chips for extra delight.
