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!!
These are insanely delicious and so easy to make. In fact I’m making another batch tomorrow!!
I just made these; they’re were easy to prepare. I used the double recipe feature, cut back a whole cup of chocolate chips, added a cup and a half of pecans and cut back 1/2 cup on the sugar and they were still way too rich. The flavor is good but there’s too much chocolate in it and it’s sickening sweet. Next time I’ll cut the sugar by 1 cup and use 2 cups less chocolate chips (double recipe called for 4 cups). The bars baked up nicely and held together well. I was just dissapointed how overpowering and sweet the chocolate chips are.
I only have quick oats in my cupboard, will these be ok?
They will work great, the oat texture will just be more fine. Enjoy!
I made these today and my family and I really enjoyed them. I had to use dark brown sugar and also regular old-fashioned oats but they still turned out delicious. I think the regular oats probably gave them a chewier texture but I’m not sure I might not use them again the next time I make these. Definitely need to cool them in order for them to be perfect to eat. A great sweet treat!
The recipe calls for old fashioned oats anyway 🤔…
These were so easy to put together and were incredible. I figured they were good but they were amazing. Such a great chewy texture, they were devoured by everyone!
I made these today. I do not understand the issues others are having with the baking time. I followed the recipe exactly except for adding a bit of toffee bits. Delicious. Baked in a glass pan for 28 minutes. Perfect.
Amazing and SO easy! For just my husband and me I cut the recipe in half and baked in an 8×8″ pan. They turned out perfectly!
I substituted in coconut margarine and dark brown sugar. I also decreased the chocolate chips by a half cup, but added walnuts and dried cranberries. The end result was crispy on the outside and chewy on the inside.
Could I make this without the flour, just the oats?
We haven’t tried it without flour but the consistency won’t be the same and it won’t bake the same way.
Loved this recipe! We used 1 cup of mini chocolate chips and 1 cup is sweetened coconut instead of 2 cups of chips. We also used 1 tsp vanilla and 1 tsp almond extract. Delicious!!
