Ingredients You’ll Need

1 cup unsalted butter: Use melted and slightly cooled for the best texture; can substitute with an equal amount of margarine or coconut oil.
1¼ cups light brown sugar: Packed for sweetness and moisture; dark brown sugar can be used for a deeper flavor.
½ cup granulated sugar: Balances the brown sugar’s richness; can swap with coconut sugar for a healthier option.
2 large eggs: Adds moisture and structure; room temperature eggs blend better.
2 teaspoons vanilla extract: Pure vanilla extract helps elevate the flavor; imitation vanilla is a budget-friendly alternative but may not be as flavorful.
2¾ cups all-purpose flour: Provides the base structure; for gluten-free options, substitute with a 1-to-1 gluten-free flour blend.
2 teaspoons cornstarch: Ensures a chewy texture; can be omitted but may affect the final result.
1 teaspoon baking soda: Helps the bars rise; make sure it’s fresh for the best results.
½ teaspoon baking powder: A little boost for fluffiness; can use baking soda exclusively, but texture may vary.
1 teaspoon fine salt: Balances sweetness; using kosher salt will change the texture slightly.
2 cups semi-sweet chocolate chips: Divided into 1½ cups for the dough and ½ cup to sprinkle on top; you can swap with dark chocolate for a richer taste.
Flaky sea salt for finishing: Adds a delightful contrast to the sweetness; can be omitted if you prefer a sweeter treat.

How to Make Thick & Chewy Chocolate Chip Cookie Bars

Preheat your oven: Set your oven to 350°F (175°C), and prepare your baking pan by greasing and lining a 9×13-inch metal baking pan with parchment paper. This prevents sticking and makes cleanup a breeze.
Mix the wet ingredients: In a large bowl, whisk together the melted 1 cup of unsalted butter, 1¼ cups of light brown sugar, and ½ cup of granulated sugar until the mixture is smooth and shiny.
Incorporate the eggs and vanilla: Crack in the 2 large eggs and add 2 teaspoons of vanilla extract to your butter and sugar mixture. Blend until combined and slightly frothy.
Combine the dry ingredients: Add the 2¾ cups of all-purpose flour, 2 teaspoons of cornstarch, 1 teaspoon of baking soda, ½ teaspoon of baking powder, and 1 teaspoon of fine salt. Gently stir until just combined, being careful not to overmix.
Add the chocolate chips: Fold in 1½ cups of the semi-sweet chocolate chips, making sure they’re evenly distributed throughout the dough.
Spread and bake: Transfer the dough into the prepared pan, smoothing it out evenly. Top with the remaining ½ cup of chocolate chips and gently press them into the surface. Bake for 22-28 minutes, until the edges are lightly golden and the center feels just set—remember, they’ll continue cooking as they cool!
Cool and finish: Allow the cookie bars to cool completely in the pan. Once cooled, sprinkle with flaky sea salt for that delightful finishing touch. Cut into squares and enjoy!

Storing & Reheating

These Thick & Chewy Chocolate Chip Cookie Bars are best stored at room temperature in an airtight container for up to 5 days. If you’d like to keep them longer, they can be refrigerated for up to a week in a sealed container. For extended storage, place them in a freezer-safe bag and freeze for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature or microwave for about 10-15 seconds until warm—perfect for that fresh-out-of-the-oven taste!

Chef’s Helpful Tips

Don’t overmix the dough: Mixing too much can lead to tough cookie bars; stir just until combined!
Use room temperature eggs: This helps them blend perfectly with the mixture for a smooth batter.
Check baking times: Ovens can vary, so start checking the bars around the 22-minute mark to avoid overbaking.
Make-ahead option: Prepare the dough a day in advance, store in the fridge, and bake when you’re ready for a warm treat.
Play with add-ins: Feel free to experiment by adding nuts, oatmeal, or different types of chocolate for variety!

These cookie bars are everything you could want in a sweet treat—rich, sweet, and perfectly chewy. There’s something undeniably satisfying about cutting into a warm, soft bar and watching the chocolate melt slightly. I encourage you to consider personal touches or variations that reflect your taste! Whether you keep them classic or make them your own, these Thick & Chewy Chocolate Chip Cookie Bars are sure to impress.

Recipe FAQs

Can I use different types of chocolate for these bars?

Absolutely! While semi-sweet chocolate chips are classic, feel free to swap in milk chocolate, dark chocolate, or even white chocolate chunks for a different flavor profile. You could even use a mix for an indulgent treat.

How can I ensure these bar cookies stay chewy?

Avoid overbaking them! The key to achieving that soft, chewy texture lies in pulling them out of the oven when the edges are golden but the center is still slightly underbaked. They will continue to cook as they cool.

Can I make these cookie bars gluten-free?

Yes! Simply replace the all-purpose flour with a 1-to-1 gluten-free flour blend. Additionally, check that your baking powder and baking soda are certified gluten-free to ensure they match your dietary needs.

What toppings can I add to these cookie bars?

Get creative with your toppings! In addition to the flaky sea salt, consider drizzling some melted chocolate on top after they cool, or sprinkle chopped nuts, like walnuts or pecans, for an extra crunch.
