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.

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!!
Comes together quick and easy. Tasty too! I used dark chocolate and cup-for-cup gluten free flour and they came out perfectly. Thank you for this recipe!
Loved these! Made them for a catering I had for some guys working on our garage/ shop. Not any left and I doubled the recipe. 😍
Can this recipe be used for cookies?
Yes, that would be fine, or try my popular Oatmeal Chocolate Chip Cookie recipe: https://tastesbetterfromscratch.com/mrs-fields-oatmeal-chocolate-chip-cookies-2/
This is too gorgeous and very easy to make . Will try using cranberries next time or I guess any dried fruit.
I only had medium sized eggs and it was still superb. May have over baked them as I was expecting them to be more chewy but still fantastic
A must bake
Does this make a good cookie too?
Hi, these sound so good! I’m just wondering if I can substitute quick oats as that’s what I typically have on hand?
I’m making these tomorrow afternoon for church! These gotta be very tasty!!
Easy and delicious! I did one cup choc chips and one cup on chips. Used gluten-free cup-for-cup flour as well. Baked perfectly! Will certainly make again.
Excellent recipe! Easy to make and such a crowd pleaser! Will definitely be making it again and have already been asked where I got the recipe. Thank you for sharing!
I made these last Sunday for dessert at my mom’s house. Everyone loved them. I realized that they were even better the next day when the chocolate chips had set. I made them again this weekend for my daughters’ theater cast. They are so easy to make and since they are even better the next day they are perfect for a busy schedule.
I hope to try them with raisins in the near future.
