Weekends are my weakness when it comes to sweets. I usually go for cookies or bars of some sort because I can always count on having the ingredients on hand.
These Oatmeal Chocolate Chip Cookie Bars are a regular, sweet-tooth-satisfying weekend treat at our house!. Chewy, chocolate and oat goodness in every single bite!
How to make Oatmeal Chocolate Chip Cookie Bars:
Beat butter and sugars: In a large mixing bowl beat together the butter, brown sugar, and white sugar until smooth and light.
Add eggs: one at a time, mixing after each addition. Add the vanilla.
Mix dry ingredients: In a separate bowl combine the dry ingredients: salt, baking soda, baking powder, flour, rolled oats, and 1 cup chocolate chips.
Combine: Add dry ingredients to the butter mixture and stir until combined. Add chocolate chips.
Press into greased pan.
Bake for 25 to 30 minutes or until golden brown. Allow to cool completely before cutting.
Storing and Freezing Instructions:
Storing instructions: Store covered at room temperature for 5 days or store in the fridge for 7-10 days.
Freezing Instructions: For best results, allow pan to cool completely. If you used parchment under the bars, lift the cooled bars out of the pan. Wrap the whole bar brick in plastic wrap and then aluminum foil. Freeze for up to one month. Thaw completely in the fridge before cutting into bars.

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 tried it for a work gathering and everyone loved them.
Love these and so does everyone else! I use half chocolate chips and half peanut butter chips. Makes a great sweet to bring along to Buckeye watch parties!
That combo sounds delicious!
My family loves these! Super easy and delicious. Another hit from TastesBetterFromScratch!
Delicious! I made these for the first time for a group of teenagers and they were all gone by the end of the night. I also threw in some raisins with the chocolate chips, and it was pretty good!
I was wondering if you could use quick cooking oats? Would they work?
That would probably work just fine 🙂
Made this as directed except added 1 tsp cinnamon. Everyone here at home enjoyed them! My husband took some to work and they were enjoyed there as well! Will definitely make these again.
Great recipe! I ground some oatmeal in my food processor to make oat flour to use instead of all-purpose. They still turned out really good!
Truly seriously delicious Oatmeal Chocolate Chip cookie bars. I can’t wait to make them again and share this . I’m not a baker and don’t typicalky reach for the oatmeal cookie if there are other choices. But I tried to find a recipe that matched with the basics in my kitchen pantry. I used half chocolate and half butterscotch chips. I really wouldn’t matter what flavor…. I’m sure the results would be that same. Easy, quick, perfect.
I’m so happy you liked it, and I love the idea of adding butterscotch chips. YUM! Thanks for sharing.
Made these yesterday for a BBQ and they were a hit. Came out perfect, looked just like the picture. I was concerned because some reviews said they were not done in the middle and too brown on the edges. Mine cooked about 28 minutes. Will definitely make again. Thanks for the recipe .
I’m so happy you enjoyed them! Thanks Jean 🙂
Oh my. Made these yesterday and they are GOOD. This is definitely going in my keeper box. Thanks for a delicious treat!
