Chocolate Chip Cookie Bars Recipe
Ingredients
- 1 1/3 cups white sugar
- 2/3 cup packed light brown sugar
- 1 cup unsalted butter, softened
- 2 large eggs
- 2 teaspoons vanilla extract
- 3 cups all-purpose flour
- 1 teaspoon baking powder
- 1 teaspoon kosher salt
- 3/4 teaspoon baking soda
- 2 cups mini semisweet chocolate chips
- 1 cup toasted, chopped walnuts
Directions
- Preheat the oven to 350F (175C). Gather all the ingredients and set them aside for easy access.
- Line the bottom and sides of a 13x9-inch baking pan with heavy-duty aluminum foil, leaving a 2-inch overhang on all sides. Lightly spray with baking spray and set the pan aside.
- In a stand mixer fitted with the paddle attachment, beat together the white sugar, brown sugar, and softened butter on medium speed until the mixture is light and fluffy. This should take about 3 minutes. Stop and scrape down the sides of the bowl as needed.
- With the mixer running on low speed, add the eggs one at a time, beating until each is just combined before adding the next. Add the vanilla extract and beat until incorporated.
- In a medium bowl, whisk together the flour, baking powder, salt, and baking soda until fully combined.
- With the stand mixer running on low speed, gradually add the dry flour mixture to the wet ingredients. Beat until almost fully combined, about 2 minutes, stopping occasionally to scrape down the sides of the bowl.
- Stir in the mini semisweet chocolate chips and toasted chopped walnuts until well combined.
- Transfer the dough into the prepared baking pan, spreading it into an even layer with a spatula.
- Bake in the preheated oven for about 35 to 40 minutes, or until the cookie is golden brown and set. Be sure to rotate the pan halfway through for even baking.
- Remove the pan from the oven and let the cookie cool completely in the pan on a wire rack, about 1 hour.
- Once cooled, use the foil overhang to lift the cookie out of the pan. Place it on a cutting board and cut into 24 squares, each about 2 inches in size.
- Serve and enjoy your delicious homemade cookies!

Chocolate chip cookie bars are an irresistible treat that combines the classic flavors of chocolate chip cookies with the convenience of a bar-style dessert. These easy-to-make bars are a fan favorite for parties, gatherings, or simply as a sweet snack to enjoy with a cup of coffee. With their chewy texture and delicious blend of mini semisweet chocolate chips and toasted walnuts, chocolate chip cookie bars are sure to satisfy any sweet tooth.
History of Chocolate Chip Cookies
The origin of chocolate chip cookies dates back to the 1930s in Massachusetts, USA. Ruth Wakefield, the inventor of the chocolate chip cookie, ran the Toll House Inn, where she first created the now-famous treat. The story goes that Ruth accidentally broke up a Nestl chocolate bar and added it to her cookie dough, expecting the chocolate to melt into the dough. Instead, the chocolate held its shape, resulting in the creation of the chocolate chip cookie. Over time, this cookie became an American classic and was later popularized further when Nestl partnered with Ruth to produce chocolate chips, which are now a staple in kitchens worldwide.
Regional Variations
Chocolate chip cookie bars have regional variations across the United States. In some parts, you might find them made with additional ingredients such as peanut butter chips, caramel, or even chunks of brownies mixed into the batter. Some areas add a pinch of sea salt on top for a salty-sweet contrast. While the traditional recipe sticks to the classic chocolate chip and walnut combination, variations are common, with some people even substituting oats or coconut flakes for a unique twist. Each variation brings something different to the table, but the core concept of soft, chewy bars with chunks of chocolate remains the same.
How Chocolate Chip Cookie Bars Differ from Traditional Cookies
While both chocolate chip cookie bars and traditional chocolate chip cookies share the same basic ingredients, they differ in texture and ease of preparation. Traditional cookies are individually scooped and baked on a baking sheet, resulting in a crisp exterior and soft center. On the other hand, cookie bars are baked in one large pan and cut into squares once they cool, offering a more uniform texture throughout. Cookie bars tend to be a bit chewier and thicker than traditional cookies, making them a more filling option for those craving something hearty.

I baked this dish in a nonstick 9 x 13 pan without using aluminum foil and didn't face any issues with it sticking. However, it turned out slightly dry even though I baked it for the full 40 minutes. I plan to try baking it for 30 minutes next time. Despite this, I will definitely make it again as it had a good flavor.

I made a delightful twist to the recipe by replacing one cup of flour with ground oatmeal. With only a 10 oz. bag of chocolate chips on hand, I mixed in peanut butter chips until I reached two cups. I also threw in crushed macadamia nuts and pecans, simply because that's what I had available. The end result? A delicious batch of kitchen sink cookie bars that turned out unexpectedly tasty!

I tried out this recipe with a small change - I left out the walnuts and threw in an extra cup of chocolate chips instead (since my grandkids aren't fans of nuts). The addition of mini chocolate chips was a pleasant surprise as I'd never used them in my bar cookies before. However, I was a bit disappointed that the cookies turned out crunchy instead of chewy.

I enjoyed the chocolate chip bars and plan to make them again. I baked them for the full 40 minutes, but I think they would have been better at around 35 minutes as the edges were a bit crispy.

These were gone in a flash! I adored the toasted walnuts in them. Can't wait to experiment with toasted hazelnuts next time!
