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.

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!!
Recipe is super easy and straightforward! Ingredients are easy to get too!
Didn’t like this at all. Not nearly enough oats. You can barely tell there’s oats in it. Needs twice as many. I’ve made other chocolate oatmeal bars and they’ve been far better than this. These bars just come out like like “wheat like” cake bars. Perhaps the recipe amounts are wrong. But my advice is to find another recipe that has more oats in it.
Thats doesn’t make sense. Most oatmeal cookie recipes call for 2-3c of oats. Only use old fashioned and melted butter instead of softened. Never use quick oats because itll suck up all the moisture and steel won’t cook at all . If you generally put more oats then you’ll dry it out even more. Always under bake cookies by taking off 5min to have chewy gooey center.
After sitting overnight this recipe went from dry to moist. I added raisins. We loved them and I will make them again. Easier than cookies. Thank you!!
Delicious and easy! Chocolatey, chewy, perfect to take to parties, picnics and potlucks
Kinda dry, was expecting it to to be more “gewy” for lack of a better term.
The taste is a five, but the edges baked higher and crispier than the rest. They taste great, too, but just wondering how to prevent that from happening.
Sift all dry ingredients together before mixing To avoid different parts of the batter baking differently. Baking powder wasn’t evenly incorporated. Also before putting it in the oven, bang the pan on the counter to get all the trapped air out. When doing so, you see bubbles float to the surface of the batter and pop. It my favorite part
Same thing happened to me
These were really good and quite easy. I used a combination of semi sweet chocolate chips and peanut butter chips (one of my favorite combos) and they turned out great!
These were ok, but I was hoping for something that tasted like an oatmeal cookie with chocolate chips. If you are looking for a bar that tastes like a chocolate chip cookie this is for you.
Great bar cookies and less time consuming than cookies. I used 12 of chocolate chips, 1/2 c of raisins and 1/4 c of chopped pecans. Yummy!
I rarely leave comments but these where absolutely delicious! My grandson asked me to make something delicious for his church group, so I used this one and they were devoured!
I made them as is, wouldn’t change a thing
