Bar cookie lover? Don’t miss out on these Funfetti Sugar Cookie Bars, Boozy Bacon Pretzel Peanut Butter Bars and Orange Cranberry Bars!

For our older daughter’s first birthday, my husband insisted on a cookie cake, even though I was already baking strawberry cupcakes.

And so we did. When our daughter bit into one of the little cookie bar squares, her eyes lit up.

And these cookie bars right here? We’ve been making ‘em ever since.

Why I love this recipe:

Other than the sentimental value these Chocolate Chip Bar Cookies have, they’re an excellent treat.

The interior of the bars is gooey (when warm) with a slightly chewy exterior. The chocolate chips add nice pops of sweetness with a hint of bitterness from the dark chocolate.

The combination is just lovely. And these bars make for an easy homemade treat to serve for various occasions. So whether you’re hosting a birthday party, attending a backyard barbecue or visiting friends for a play date, I encourage you to bake these!

The beauty in these bars is that you don’t have to chill the dough. Also, you can mix them, bake them and get them out of the oven in less than an hour, which is a massive WIN!

What you’ll need to make this recipe:

• Stand mixer (or a hand mixer and mixing bowl)
• Nonstick cooking spray
• 9” x 13” baking pan
• Offset spatula

In addition to these tools, you’re going to need some ingredients, too.

Please be sure to scroll all the way down to the recipe card to get the exact amounts!

• Unsalted butter—this needs to be at room temperature so we can easily cream it with the sugars. There is no substitute.
• Granulated sugar—also known as white sugar, this gives our bars a lovely sweetness.
• Brown sugar—you may use light brown or dark brown sugar here. The dark brown sugar will give more molasses flavors than the lighter one, but both work.
• Eggs—these provide structure, as well as some leavening for our cookie bars.
• Pure vanilla extract—we use a lot of it, but trust me on this. It adds such loveliness to the batter and final cookie bars.
• All-purpose flour—we keep unbleached AP flour at our house, but you can use whatever you’ve got at your house. I have not tried to make this recipe with a gluten free substitute flour, so I do not recommend doing that.
• Kosher salt—I like to use a fine grain kosher salt for this recipe. Fine grain sea salt would also be OK.
• Baking soda—this is our leavening agent, and it helps these bars rise a little! Please do not replace it with baking powder. That will make for a fluffier end product, which is not what we are going for.
• Chocolate chips—we are using a combination of bittersweet chocolate chips and dark chocolate chips here. If you don’t like these two, consider using semi sweet chocolate chips or milk chocolate chips. Please note that if you use these, your final bars will be a little sweeter.

How to make Chocolate Chip Cookie Bars

Prepare. Spritz a 9″ x 13″ pan with nonstick baking spray. (You can also line with a little parchment to create a sling.) Remove the butter and eggs from the fridge so they can come to room temperature. Preheat oven, too.

Cream the butter and sugars. Measure the softened butter, granulated sugar and brown sugar into the base of a stand mixer. (This can also be done in a large bowl with a hand mixer.) Use the flat beater attachment to cream these together until light and fluffy, about 2-3 minutes.

Did you know? Creaming the sugar and butter makes a fluffy, light cookie bar. The process adds air the batter, creating air pockets so the dough can rise more when it bakes.

Scrape down the sides of the bowl with a rubber spatula.

Add the eggs and vanilla. Beat until combined. Don’t forget scrape down the sides again to ensure all the ingredients actually mix in.

Measure in the dry ingredients. Gently scoop the flour, salt and soda into the mixing bowl. If you’re baking with kids, this part is a blast and also a little messy.

Pro tip: Turn on the mixer at a low speed at first so you don’t get covered in flour.

Next, add chocolate chips. Mix until combined!

Make the cookie bars. Dollop the batter into the prepared pan, and spread using your hands or an offset spatula.

You can spray your hands or a spatula with nonstick baking spray to ensure the batter doesn’t stick.

Once the dough is spread into the pan, pop it in the oven and bake until golden brown and delicious.

These Chocolate Chip Bar Cookies are just the best kind of dessert for entertaining because they’re simple to put together, utterly delicious and feed a crowd.

Frequently Asked Questions

Quick tips for making Chocolate Chip Cookie Bars

• Make them dairy free. Substitute equal parts coconut oil and applesauce for the butter. This will make for a softer cookie bar, but they’re still delicious. We’ve made them this way tons of times.
• How to store: Store on a plate wrapped in plastic wrap or covered in the original baking dish for 3-5 days. (They never last that long in our house, though!)
• How to freeze: Transfer the baked cookie bars to a wax or parchment-lined baking sheet. Place in the freezer, and freeze for 4-5 hours, or until solid. Transfer to a freezer bag and keep for 3 months in the freezer. Reheat in the toaster oven, or let come to room temperature on the countertop before enjoying.
• Switch out the chocolate. If you don’t like darker chocolate, use milk chocolate chips or semisweet chocolate chips instead. Those will make these cookie bars sweeter, so aim to use about a cup.
