The ingredients for making Sheet Pan Cookie Bars include: butter, brown sugar, vanilla, eggs, flour, baking powder, and salt.

  • Chocolate Chips: For this recipe I like to include both white and milk chocolate chips. I like the way the flavors play off each other. You can always use all milk or semi-sweet chocolate chips, or switch it up with peanut butter or butterscotch chips.
  • Brown Sugar: The brown sugar helps make these cookie bars extra soft and sweet. The original recipe called for 3 cups of brown sugar instead of 2. If you are looking for a truly decadent and sweet bar, you can increase the sugar amount.
  • Butter: I always use unsalted butter in baking. Be sure that your butter is at room temperature before you get started.

Read on to see how easy this recipe is to make!

First, make sure you are using a large mixing bowl or stand up mixer. Preheat the oven to 350 degrees and prepare your sheet pan by coating it with nonstick cooking spray.

Step 1: In a large mixing bowl, cream together the butter and brown sugar using a hand mixer; about 2 minutes. Then add in the eggs and vanilla and mix until well combined. To the same bowl, add in the flour, baking powder, and salt. Mix again until just combined.

Step 2: Then, pour in a bag of milk chocolate chips and a bag of white chocolate chips, saving some chips to sprinkle on top of the bars.

Step 3: Use a rubber spatula to mix in the chocolate chips, scraping downs the sides of the bowl as you go. Be sure to incorporate all of the ingredients into the batter.

Step 4: Press the batter into your prepared sheet pan. The mixture will be sticky. My best advice to get the batter into the pan is to press it down using damp hands. To do this, wet your hands slightly and press the cookie dough into the pan.

Sprinkle the remaining chips over the top of the cookie batter. No need to press them in.

Bake on the middle rack for 20-25 minutes until lightly golden.These bars will bake fast. Be sure to pull them out of the oven when they start to turn golden in color.

Next, let the cookies cool on a wire rack for at least 15 minutes. Then, you can cut the bars directly in the pan and lift them out.

This recipe easily makes 40 large cookie bars, 60 medium, or 80 if you are cutting them smaller. You and refrigerate them for up to two weeks or store them in an airtight container at room temperature for three days.

Sheet Pan Cookie Bars are a great way to make treats for a crowd. To ensure the best bars every time, check out my expert tips:

  • Use room temperature unsalted butter.
  • Mix the butter and sugar until the batter is light and fluffy; about two minutes.
  • Use good quality chips for this recipe. I like Nestle or Ghirardelli brand.
  • The best way to get the batter into the sheet pan is to press it down with damp hands.
  • Don’t over bake the bars. Take them out right when they start to turn golden brown.
What is a cookie bar?

The dough for a cookie bar is the same as the dough you would make for a cookies. However, instead of making individual cookies, they are baked in a baking pan, or in this case a sheet pan. The result is a fluffier more brownie-like cookie texture.

Can you make cookie bars in a sheet pan?

Yes! You will just need to double the recipe in most cases. Press the cookie batter into a greased sheet pan and bake until golden in color.

How to store cookie bars?

There are a couple of options on how to store cookies bars. Either way, they must be kept in an airtight container. Store at room temperature for up to three days, in the refrigerator for up to two weeks, or freeze for up to two months.

  1. I am a ranch wife, sports mom, aunt that always hosts. I love these bars for any occasion. They feed a coffee breaking cowboy crew, a snacky team, and the whole in-law clan.
    I appreciate the recipe and how easy they come together.

  2. 5 stars
    These are absolutely fabulous, but be forewarned it’s impossible to eat just one. I’ve made them about 4 times since June and they are so quick and easy to make. I recently took them to a family gathering and they got rave reviews from everyone and a request for the recipe. I love that they feed a crowd. There’s nothing I don’t like about this recipe. Thank you so much for sharing it. : )

      1. I rarely take the time to go back and review recipes. This may be the first time, actually. These are so good and so easy. I didn’t change a thing except after much deliberation, I made 2 10 x 15 pans of them. I no longer have a big sheet pan and I thought it was too much dough for 2 9x13s (even though that’s what an 18×13 is 🙄). It worked perfectly. I got a great yield and they were still soft and delicious. Thank you for this recipe. It was a delight.

      2. Thanks so much for the comment, Phyllis! I’m so happy you enjoyed them 🙂

    1. Yes. I usually spray the entire pan with cooking spray and then just place a liner at the bottom of the pan.

  3. 5 stars
    guys! – LIFT the parchment paper and don’t drag it out like i did b/c they cracked 🙁 (???i don’t what i was thinking!)
    I just made these and they are soooooooooooooo good!
    Thank you for an easy recipe.
    I baked for 30 minutes plus a tad more because i couldn’t tell if they were done even though they were golden.
    Used a bag of peanut butter & choc chips and a bag of choc chips just b/c i’m not a white choc fan.

    1. Thanks for the tip! Also, I love that you used peanut butter chips instead… one of my absolute favorites. YUM!! 🙂

      1. i will say that even though i had cracks, with the texture of these, they still held together well when cooled completely and cut. Also they did not need the extra cook time beyond the 30 minutes b/c the inside texture was still the same (soft).
        Plan to make them again and try butterscotch & choc chips!! The chip manufacturers have just gone wild with all the choices out there these days!!

      1. But what size do you consider standard? I have a quite large one but I’d love to know dimensions of pan you used.

      2. I use a 18 x 13 inch pan, which is actually considered a baker’s half sheet.
