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!!
I added a 1/2 cup of peanut butter. Delicious!!
I’m not a big fan of oatmeal cookies but tried this recipe with a few tweaks and loved it! I cut back on the sugar by 1/4 cup for both white and brown, then added 1 cup mini semi sweet chips and 1 cup toffee chips. Can’t stop eating them!
Everyone in the house loved these. Easy and really great! I added about 1/3c of toffee chips to the chocolate chips in the center. Winner 🙂
oats very healthy and you can use carob or dark chocolate
Hi. I’m looking forward to making this recipe. I’m hoping subbing Crisco for the butter will be fine. We are dairy free here and I make my regular oatmeal cookies with crisco. We use vegan mini chocolate chips and can’t tell the difference in flavor.
Thank you for your recipe, it sounds delicious 😋

This was my first time making cookie bars. These are delicious – a yummy combo of a chocolate chip cookie and oatmeal cookie. I halved the recipe and baked it in a 9×9 pan for about 24 mins and they came out perfect! I had difficulty spreading half the cookie dough so I just put it all in at once and topped it with chocolate chips and pecans. Will definitely make again!! Thank you for the recipe.
pecans ooo, even better, great idea
I came across these on a search for this type of bar. I made them today and they are delicious. My husband loves them. I also put all the chocolate chips in at one time. I tried putting them in the middle on a recipe one time. Mercy, it was hard to spread the top layer over the chips. I really can’t tell it matters. I cooked mine at 325 in a USA 13×9 pan. I used milk chocolate and semi sweet chips. GREAT RECIPE!!
Thanks for this recipe!
Could you use self rising flour and leave out salt and baking powder?
My favorite easy dessert!
These are really, really good! I added chopped walnuts.
