Oatmeal Cookie Bars Mean Business!
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:

Add remaining chocolate chips.

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!!
Hi! Do u use unsalted butter?
Yes I do!
I need diabetic friendly recipies, has anyone tried this with other flours like gluten free or almond? I think Oat flour maybe too much with the oats. What about subbing sugars with coconut, Monkfruit brown sugar? I am hopeful, this looks yummy-i would eat too much if I didn’t change it to less carbs/sugars!! The family would fight me for it LOL
Thanks

Can you add nuts?
Absolutely—you can definitely add nuts to this recipe! Chopped walnuts or pecans work especially well. I’d recommend folding in about ½ to 1 cup of your favorite nuts along with the chocolate chips.
Can you make these with out egg?
Yep! Try a flax egg (1 Tbsp flax + 3 Tbsp water) or ¼ cup applesauce as an easy egg swap—it works great in these!
I made this once and brought them to work, they love it. So I’ve been making them ever since. However, I cut down the amount of sugar and sub it for coco sugar also the chocolate chips 1/2 cup instead.
Could I use instant oats with this recipe?
Yes, instant oats work! The texture may be softer than with old-fashioned oats, but it’ll still be delicious.
I LOVE THESE BARS!!!
I have made these bars several times and they are ALWAYS a crowd pleaser! They are so chewy! I actually love them better than an oatmeal chocolate chip cookie because they are much thicker. I have frozen them after baking and they taste amazing, just leave them out for a bit. I also don’t add all 2 cups of chocolate chips, maybe 1 1/2 cups, I want to taste the oatmeal! This will be a favorite if you love oatmeal cookies. Make sure you don’t over bake them.
