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.

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!!
Can u replace the chips for raisins?
Sure! Sounds yummy
Can you double the recipe
I’ve been craving a soft oatmeal chip cookie for weeks and finally had some time to bake! I love cookie bars for the all cookie flavour and texture without all the scooping, cookie shuffling and bake time. This recipe does not disappoint!!!!
I agree! I love how much easier these are, and they still taste amazing!
Great recipe. I forgot to put the chocolate chips in the middle and ended up putting them on top.
I added shredded coconut and walnuts.
Turned out great.
These are incredible…totally my go to treat recipe! Just brought to an Easter gathering and the host already asked for the recipe. The dough is a little difficult to spread because you divide in half, but worth the little bit of extra effort. Doesn’t have to be perfect and they still turn out great! Thanks for sharing!
Thanks so much for the positive feedback, Michele!
Now this is a snack I can really get behind! I love oatmeal in pretty much anything, but the chocolate? YESSS!!
These are my go to recipe for cookies. My husband LOVES chocolate chip cookies, but I am not crazy about cookies. These are a fantastic comprise!
Delicious I did make the 9 X 13 inch Chocolate Chips Bars Except: I added Pecans and Wheat Germ which gives it a
yummy nutty flavor and full of Vitamines and Pure Delish
This time I am doing as before except when it will be out of the oven I am going to put some candied broken pieces
of Skor on top, very very little no more than a 1/4 of a cup but will give a good taste and not sure it will be dectected
by eye But we all will know!
Can I freeze extra already naked bars for a week or so? Will they still taste fresh baked-ish once defrosted? Thank you
yummy and very easy to make!
These are great. My family love anything chocolate chip and having the oatmeal is just an added bonus. Thank you for all the wonderful recipes.
I made this and even though the batter was pretty much a nightmare to handle, they baked beautifully! I used a 9″ square pan I had to make a second batch to be able to top it.
