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.

Homemade Oatmeal Chocolate Chip Bars cut into squares on parchment paper, ready to enjoy.

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.

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 easy Oatmeal Chocolate Chip Cookie Bars are perfectly baked with a chewy, chocolatey texture. They are everyone's favorite!

Storing Instructions: Store covered at room temperature for 5 days or store in the fridge for 7-10 days.

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 wanted cookies but not all the work of cookies so I searched for a bar recipe. Found this one and it is perfect! Chewy, crunchy, yummy! Followed the recipe exactly and will definitely make again.

Could this recipe be used for cookies instead of just the bars? Also, I have made these a couple and they are delicious, however, they bake and rise then as they cool, they fall.

Ingredients on hand, easy to make and delicious!!

Personal preference only, I omitted 1/2 c of white sugar and only added 1 cup of chocolate chips cause I love a good cookie base, still delicious 😋

So delicious! A perfect dessert that tastes just like a cookie but so much easier to make. I did half the amount of choc chips and would recommend the same. Still very chocolatey!

These are phenomenal! I am picky about chocolate chip bars- I like them to be chewy and not crunchy. These turned out perfect and are so delicious. Saving as a favorite recipe to make again.
