As you can see, there are only 10 ingredients in this chocolate chip cookie bar recipe, all of which you likely have on hand at all times! We’ll chat briefly about the ingredients and possible substitutions before we jump into the “how-to” make this cookie bar recipe!

All-purpose flour. I recommend using unbleached, all-purpose flour in these cookie bars. For a gluten-free version, use an all-purpose gluten-free baking flour.
Brown sugar. I love the flavor of light brown sugar in this cookie bar recipe. If you like a deeper, molasses taste, use dark brown sugar.
Granulated sugar. white or organic cane sugar are great choices.
Salted Butter. unsalted butter, ghee or coconut oil are all good substitutes. Or, try using brown butter for a rich, caramel flavor.
Sea salt. Sea salt is different than table salt (that is iodized), so if you use table salt I recommend using half the amount called for in the recipe.
Chocolate chips. Choose your favorite chocolate chip variety to use in these cookie bars! I prefer dark or semi-sweet chocolate chips. If you have an excess of candy in your house (think, post-Halloween) try making this Candy-Stuffed Cookie Bar variety!
- Can I use chocolate bar instead of chocolate chips? Yes! You can use chopped chocolate in place of the chips.

Ok, now that we’ve chatted about the ingredients in this cookie bar recipe, let’s dive in and get baking! Remember to watch the video for the step-by-step process!

Start making these cookie bars by creaming together the butter and sugars until the ingredients are evenly combined

Next, add vanilla and egg and beat again until the ingredients are mixed well and the sugar is dissolved!

You can either mix the dry ingredients together in a separate bowl before you begin the rest of the recipe – which I recommend to ensure even distribution – or just toss them into the mixer on top of the beaten wet ingredients.

Either way, beat them in until they are just combined and the dough is uniform throughout.

Add in your favorite chocolate chips (or other mix-ins of your choice) and stir on low speed until they are evenly distributed throughout the dough!

If you’d like to add different mix-ins to this cookie bar recipe, here are some suggestions:

Sprinkles. Choose your favorite sprinkles to make these cookie bars festive! Red and green for Christmas, black and orange for halloween! You can’t go wrong!
White chocolate. Add some white chocolate chips or chunks!
Peanut butter chips. LOVE this addition!
Cinnamon chips. YUM!

Bake

Line and grease an 8×8″ baking dish. Transfer the cookie bar dough to the baking dish and use a spatula to press it into the pan until the top is even. If desired, sprinkle a few extra chocolate chips on top!

Bake these chocolate chip cookie bars for about 20 minutes. Please note: I use a convection oven (one that uses a fan to distribute heat evenly), so I don’t have to worry about the rack I bake on, hot pockets in the oven, etc.

All Ovens bake differently

Make sure you know your oven. Does it have hot pockets? Where do things tend to bake most evenly? Invest in an inexpensive oven thermometer to check the temperature and ensure the internal temperature is actually the temperature to which the oven is set. If your oven is baking too hot or too cold, then the cookie bars might burn on the top and still be gooey in the center

Cool, Cut & Serve

Finally, let the cookie bars cool for at least 30 minutes. The longer they cool, the better they hold up to cutting. If you’re just going to serve them warm with vanilla ice cream, then I wouldn’t worry too much about their appearance, because the taste and warm gooey texture is most important in that situation!

Store/Freeze

Store these cookie bars in an airtight container in the refrigerator for up to 1 week, or in the freezer for up to 2 months.

Can I double this recipe?

Yes, double the ingredients and bake in a 9×13″ glass baking dish for 25-28 minutes.

How many bars does a 9×13 pan hold?

If you double this recipe and make it in a 9×13″ pan, you can make up to 36 bars depending on size.

Do cookie bars harden as they cool?

Yes, these cookie bars become firm as they cool. When they are fresh from the oven they are soft and gooey. But they do harden as they come to room temperature.

What are bar cookies?

A bar cookie is simply a cookie baked in a bar form. You can take almost all of your favorite cookie dough recipes and turn them into bar cookies! They are gooier and easier to make!

How do you cut bar cookies cleanly and evenly?

Here are my tips on getting clean, even squares:
Let the cookie bars cool all completely to room temperature before cutting.
Use a very sharp, long knife.
Dip the knife in warm water and quickly dry it off before the first cut. Then wipe it clean, dip it in warm water, then dry again before each subsequent cut.
Use a ruler to measure equal pieces. If cutting these cookie bars into 16 squares, you’d want each bar to be 2″ x 2.”

How do you know when cookie bars are done?

These chocolate chip cookie bars are done when the edges are lightly golden brown and the top is set. They will jiggle slightly when removed from the oven.
