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.

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 were yummy. My husband loved it. I think next time I will swap 1 cup of chocolate chips for walnuts.
I was wondering, why cant we just mix all of the chocolate chips at the same time instead of the 2 step method? Also, would it be ok to add some chopped walnuts or pecans? Thank you sooo much for this recipe!!
You could do both of those. I like to have a defined layer of chocolate in the middle (that’s why I do the 2 steps)
I made these last week mixing 1 c. milk chocolate chips and 1 c. semisweet chocolate chips together in the dough (not layered) and they were still yummy! But the 2 different chips made a difference…want to try peanut butter chips the next time.
These bars were thick, chewy, chocolatey deliciousness! I made these for an annual picnic last weekend and they were a huge hit!

I substituted half the chocolate chips with peanut butter chips, it cut the sweetness and added a kind of almost salty sweety savory something taste that everyone LOVED.
I try A LOT of Pinterest recipes but this one my husband specifically said he’d want again and again…
Hi! I’m wanting to make these tonight and wondering if I can sub the regular flour for all-purpose gluten-free flour? Thanks!
Hi Heather, I have never baked with gluten-free flour so I’m honestly not sure, but I imagine it should be just fine. Id love to hear how they turn out!
I just made them with Gluten Free flour and they turned out great. I did add 1/4 extra baking powder because gluten free flour tends to be very flat. They turned out great.
Just put this in the oven, my preschoolers loved helping me and we can’t wait to try it! Thank you!

These are delicious! I used only 1-1/2 cups of chips because that’s all I had, but they were still delicious!
Will try this using Splenda Brown sugar substitute and regular Splenda to cut down on carbs.
Thank you from our troops! I’m making this to send to my brother who is currently in the Army in Afghanistan. In a bar form it makes it easier to vacuum seal and when they get them 10 days later they are still fresh and yummy!
That is so wonderful!! Thanks for sharing Micheala–I hope he loves them 🙂
