Oatmeal Chocolate Chip Cookie Bars

Oatmeal Chocolate Chip Cookie Bars

An easy, chewy bar cookie with oats and chocolate chips!


24 squares


1 cup (2 sticks) butter, softened
3/4 cup brown sugar, packed
1/2 cup granulated sugar
1 egg
1 teaspoon vanilla
1 1/2 cups all-purpose flour*
1 teaspoon baking soda
pinch of salt
3 cups rolled ("old-fashioned") oats
12 ounces (2 cups) semi-sweet chocolate chips**


1. Cream butter, sugars, egg, and vanilla with electric mixer on high.

2. Stir in flour, salt, and baking soda, all at the same time. Stir in oats. Last, add chocolate chips and stir them in (or use clean hands, if the dough is too stiff).

3. Press cookie dough into a greased 9x13-inch baking dish. Dough should be somewhat flattened, but it's okay for some cracks to remain. :)

4. Bake at 350 degrees for 30-35 minutes, or until lightly golden and cookies are set in the middle.

5. Cool for 20 minutes; cut into 24 squares. Delicious warm or cold! :)

Oatmeal Chocolate Chip Cookie Bars
Additional Notes: 

*I like to use a combination of all-purpose and whole wheat (or whole wheat pastry) flour. It's always turned out great!

**This makes very chocolate-y cookie bars. If you like fewer chocolate chips in your cookies, etc., you may want to halve this amount (6 ounces, or 1 cup).

This recipe was originally sent to me from Holly. I've altered it slightly, and the photos are mine, of course. :)

Preparation Time: 

20 minutes

Cooking Time:

Tammy's Review: 

This is a fabulous, super-easy bar cookie recipe! It's pretty basic, very yummy, and fast enough that the boys and I have made several pans "at the last minute" to take places. :)

I LOVE oatmeal chocolate chip cookies, and it's hard not to eat too many of these! ;) Taking them to potlucks and such ensures that the temptation isn't around too long. ;) My rating: 10/10


I love bars better than cookies...so much easier! But alot of times bars are dry and just not as yummy as their cookie cousins. These are so simple and absolutely scrumptious!


I personally don't know how good these are, not being a chocolate fan, but I made these for a potluck, and everyone said they were great! :) They were quick & easy to make.


These bars are so easy to throw together and are excellent...nice and moist and yet they taste deliciously wholesome (I used part whole wheat flour). They are our new favorite!


hope this reindexes something


I made these for everybody to snack on while my Mom was in the hospital and they were a BIG hit! I cant believe how chewy they are! I didnt feel guilty after eating them either! Try making them with whole wheat flour, you wont be able to tell the difference!


These bars were like oatmeal-chocolate chip cookies, only baked in a 9x13" pan. :) I made them with all whole wheat flour, as that's what I had on hand, and they were a bit dry and crumbly, but this could probably be fixed by reducing the amount of whole wheat flour. Overall: good flavor and 7/10.


These were wonderful. I used whole wheat pastry flour and couldn't even tell. I love how quickly they come together and taste delicious. Even better with a glass of milk. Thanks for the great recipe.


I just made these and waiting the 20mins for cool down was really tough!! They are sooooo good. I did use 1/2 the portion of chocolate chips. I also used organic all natural sugar for both the crystal and brown. The whole wheat pastry flour worked out well. I cannot even tell its wheat flour. They are fantastic!!!

**I made a couple of changes...I added an extra egg and instead of 2 sticks of butter, I did one stick and 1/2 cup apple sauce. The extra egg made the bars nice and moist and less hard and cookie-like.


i worked at a restaurant and the bars we made were many times better than these. I don't have the former recipe so I tried these. These were dry and bland tasting. I think part of the problem is that it called for 1 tsp. of baking soda. I would use only 1/2 tsp, in the future and 1/2 ti 1 tso, of baking powder. Too muc baking soda can ruin the taste. Also, bake for less time.
