Our favorite Oatmeal Chocolate Chip Bars are thick, chewy, and so easy to make! They're perfect for a crowd and are easy to transport in a 9×13 pan.
Oatmeal Cookie Bars Mean Business!
I don't know anyone who has tried these Oatmeal Chocolate Chip Cookie Bars and not immediately fell in love. They're so easy to make and I love the chewy texture from the oats. We don't skimp on the chocolate either.
Make sure to try my other cookie bar recipes, like Sugar Cookie Bars, Peanut Butter Bars, Snickerdoodle Bars, Butterscotch Blondies, and S'mores Bars.
How to make Oatmeal Chocolate Chip Cookie Bars:
Make Cookie Dough: With a hand mixer or stand mixer, beat together the butter, brown sugar, and white sugar until smooth and light. Mix in eggs, one at a time, then add vanilla. In a separate bowl, combine the salt, baking soda, baking powder, flour, rolled oats, and 1 cup chocolate chips. Pour the dry ingredients into the wet ingredients and stir until combined. Add remaining chocolate chips.
Bake: Press cookie dough into greased pan with parchment paper then bake at 350°F (180°C) for 25-30 minutes, or until golden brown. Let it cool completely before cutting and serving with a cut and serve turner.

I originally shared this recipe February 2016. Updated April 2018, May 2022 and September 2025.

These are some of my favorite bars of all time. And so easy to make. I bake mine for 27 minutes. Definitely be sure to let them cool if you plan on taking them anywhere or else they won’t be set, but when it’s just me I love digging in right away.
I bet you do
One of my go to recipes for gatherings. The pan almost always comes home empty. Thank you for sharing!!
I made this today but cut ingredients in half and pressed the dough into an 8×8 pan. Perfection. I am usually making a quick sweet for 2 or 4 so I always use my 8×8 this recipe converted well.
How long did you bake it?
Is it possible to use Quick Oats for this recipe? Thanks, Kim🌺
I’ve made these multiple times and they’ve always turned out awesome. Now it’s time to experiment with some tweaks. Perhaps raisins instead of the chocolate chips and/or adding pecans or walnuts. I will also try a batch using gluten free flour & oatmeal. Thanks for sharing.
I’m curious if you tried it with a gluten free flour mix and if you could tell the difference in the flavor / texture?
My husband & I love it. There only 1 thing it s so sweet that you have your filling after a small piece which is good because it last longer. I keep my bars in the fridge as it too warm in our kitchen.
I don’t know that I have shared a recipe as much as I have this one. The day I first made it, my house smelled amazing!! It is so easy, but sooo delicious. Baking with butterscotch and chocolate chips today, can’t wait until they are done!!!!
Hi, Lauren! I want to make your oatmeal chocolate chip BARS … but, I would like to substitute Quick Cook Oats for the Old Fashioned Rolled Oats, and I would like to substitute Sultana Raisins for the Chocolate Chips. What adjustments do I need to make to the recipe to use these substitute ingredients?
Equal parts! Enjoy!
Easy and delicious! What more could anyone want? Well, they keep well also. Probably because of the creamy butter. Butter makes everything better! We took them on a road trip and we had them for breakfast and snack and dessert quite often. They were six days old -without freezing or refrigeration- when we ate the last one but you wouldn’t know they were more than a day old. Oats are healthy,right?! They remind a little of the Chik FIL A cookies but cheaper and easier to make because they are in bar form.
Taste very much like the cookies I make which is great. Making them in bar form saves a lot of time not having to form them into cookies. You could probably make 48 bars out of the pan as they are fairly rich as others have said – but they go great with a cup of coffee. The fact that the dough is super stiff at the end will likely send me looking for alternatives as I have bad arthritis in my hands, but if you don’t have that issue, this recipe will be a keeper for sure.
Easy to make and taste FANTASTIC! I’ve made these a couple times and friends and family are also impressed.
Way too buttery and sloppy to eat. I used less chocolate chips than recipe called for based on some comments I read. Not worth the effort in my opinion.
Thanks for letting me know. I thought that was a large amount. Normally for baking recipes I substitute natural unsweetened applesauce in place of butter/oil, same ratio; always turns out perfectly, can’t taste applesauce. i might use 2 Tbs butter just for a little buttery taste but the rest will be applesauce.
