Tips & tricks for the best chocolate chip cookie bars:
- This cookie bar recipe uses melted butter making them super soft and smooth - this is a crucial part to these cookie bars!
- Do not bake for too long or else you will have a dry cookie bar with a crunchy chocolate exterior.
- Experiment with adding different kinds of chocolate chips. Milk or dark chocolate chips, white chocolate chips, or peanut butter chips are all great options! You could even add some M&M's or turn them into kitchen sink cookies with caramel and pretzels.
- Serve with a scoop of vanilla ice cream for the ultimate treat!
- Store these bars in an airtight container or freeze for later. They last up to 3-4 days, but they taste best within the first 2 days.

- Unsalted butter (melted): Salted is also fine here, just omit the added salt. Do not use margarine, as this will be too greasy.
- Light brown sugar
- Granulated sugar
- 1 egg + 1 yolk
- Vanilla extract
- Baking powder, baking soda, salt
- All-purpose flour: For a gluten-free version, use a gluten-free 1-to-1 flour but I personally like them best with half GF flour, half almond flour (like my chewy gluten-free cookie cake).
- Semi-Sweet Chocolate Chips (I use Nestle or Costco brand): Feel free to make these with your favorite chocolate chips, chunks, M&M's, or dairy-free chocolate chips!
- 9x13 pan (ideally light-colored metal)
Decorating Ideas for Chocolate Chip Cookie Bars
- Make a double batch of my cookie cake buttercream frosting to pipe on a decorative border!
- Top with flaky sea salt for an elevated taste - so, so good!
- Drizzle melted chocolate on top of cookie bars
- Add M&M's, sprinkles, crushed nuts, or almonds inside the dough or on top

Step 1: Mix Cookie Dough
Preheat oven to 350°F. Spray a 9x13 pan with nonstick cooking spray and cover with parchment paper (optional but recommended for easy removal).
In a medium bowl, mix together melted butter (¾ cup), light brown sugar (¾ cup), and granulated sugar (½ cup) and mix until combined. Add in egg, egg yolk, vanilla (2 teaspoons), baking soda (1 teaspoon), baking powder (¼ teaspoon), and salt (½ teaspoon). Mix. Add flour (2 - 2 ¼ cups, see "notes section" in recipe card below regarding flour amounts), ½ cup whole chocolate chips, and ½ cup chopped chocolate chips. Stir until combined.
Tip: Adding the chocolate chips at the same as the flour will help the chips be evenly distributed and prevent them from falling to the bottom of the bowl.
Step 2: Press Cookie Dough Into Pan
Press cookie dough into a greased, parchment-lined 9x13" pan. Once smooth, sprinkle the remaining ½ cup chocolate chips on top and lightly press each into the dough. If you see any chocolate chips stuck together or on the edge of the pan, relocate them. This will help create clean edges when cut!
Step 3: Bake
Bake at 350 degrees for 16-18 minutes or until cookie bars are lightly golden brown (do not overbake, you want to underbake slightly for a gooey cookie). Allow the cookie bars to cool completely before cutting into squares/bars! Or don't and eat a warm bar with ice cream (just note that they will look too dough & crumble a bit more when hot but will continue to bake in the hot pan!).
Step 4 (optional): Decorate Chocolate Chip Cookie Bars
To decorate chocolate chip cookie bars, you can use some of the following:
- Make a double batch of my cookie cake buttercream frosting to pipe on a decorative border
- Drizzle chocolate on top of cookie bars
- Add M'm's or sprinkle crushed nuts or almonds on top
Frequently Asked Questions
I like these chocolate chip cookie bars best with semi-sweet chocolate chips but you can also use milk chocolate chips! Dark, milk, white chocolate chips would all taste delicious in these bars, as well. Or you can always chop up your favorite chocolate bar or leftover Halloween candy for super delicious cookie bars.
The cookie bars freeze well after being baked and cooled completely. To freeze, cool the bars completely before placing them into an airtight container or freezer bag for storage. They will keep in the freezer for 1-2 months.
I used a 9x13 metal baking pan and it turned out to be the perfect size for these thick bar cookies. If you bake these in a smaller pan, you will want to use less dough (freeze the extra and bake into cookies later!) and will just need to increase the baking time.
You can also use glass, just take note that the cookie bars may need longer to bake. In general, I always recommend using metal baking pans for cookie bars.
This cookie bar recipe yields approximately 24 servings, depending on how large you cut them. For cookie platters, I like cutting these in smaller 1-2" bite-sized pieces.

Instructions
- Preheat oven to 350°F.
- Place ½ cup of chocolate chips on a cutting board and use a knife to chop into small pieces. Set aside.
- In a medium-sized microwave-safe bowl, melt the ¾ cup unsalted butter (not margarine) for 20-30 seconds until JUST melted. (If your butter is steaming, let it cool down for a few minutes. Butter that is too hot can result in greasy bars and/or will cause the eggs to cook.)
- Add in ½ cup granulated sugar and ¾ cup light brown sugar and use a spatula to stir until combined (* do not use a mixer!). Add in 1 large egg + 1 yolk and 2 teaspoons vanilla extract. Mix until combined.
- Stir in 1 teaspoon baking soda, ¼ teaspoon baking powder, and ½ teaspoon salt. Add in 2 cups all-purpose flour, 0.5 cups semi-sweet chocolate chips, whole and the 0.5 cups semi-sweet chocolate chips, chopped. Mix until all the flour disappears into the dough. Immediately proceed to the next step.
- Press dough into a greased or parchment-lined metal 9x13" pan until smooth. Sprinkle the remaining 0.5 cups semi-sweet chocolate chips, whole on top and gently press each one into the dough.
- Bake at 350°F for 16-18 minutes until edges and top are lightly golden brown. Do not overbake or your chocolate chip cookie bars will not be soft. You want the cookie bars to be lightly brown on the top and look slightly underbaked (my oven was perfect at 16 minutes). Remove from oven and place entire pan on a cooling rack.
- Allow the cookie bars to cool completely before removing from pan. Slice into 24 squares, then enjoy! To keep fresh, cover pan with saran wrap or place bars in airtight continer for up to 3 days (after that they start to dry out). See notes below for freezing tips.

This recipe is sooo good! I added extra chocolate chips of course🤭, but the idea of chopping up some of the chips is so smart. Another reason I love this is it tastes amazing the days after, without even needing to heat it up. 10/10 recommend🫶🏻
