Chocolate Chunk Oatmeal Cookies

These chocolate chunk oatmeal cookies have a crisp exterior and a chewy interior. It’s loaded with large chunks of toasted walnuts for crunch, plenty of chocolate for sweetness, and oatmeal to make it hearty!

Chocolate Chunk Oatmeal Cookies

Last month, I went through a crazy oatmeal phase. Over the course of two weeks, I managed to wipe out 5 pounds of rolled oats. (That’s half the oatmeal box sold at Costco!) I don’t particularly love oatmeal, but it was one of the few things I could eat without pain.

Let me explain.

I recently started wearing Invisalign. I had terribly crooked teeth as a kid and I wore braces in middle school. However, young Maryanne was not very responsible and she failed to wear her retainers once her braces were removed. Fifteen or so year later and my teeth are shifting. Rather than wait for my teeth to revert back to it’s original state, I finally saw an orthodontist.

Perhaps my tolerance for pain is low, or maybe I just like eating super crunchy foods. But for the first two weeks since getting my first Invisalign tray, I had the hardest time eating. Oatmeal was my comfort food.

These chocolate chunk oatmeal cookies are not very soft. They have crisp exterior with a chewy interior. There are large chunks of toasted walnuts for crunch, plenty of melted chocolate for sweetness, and just enough oatmeal to make it hearty. I would gladly eat these cookies regardless of my tooth pains.

These oatmeal cookies are soft and chewy, fresh from the oven. But they don’t stay like that too long.

You can slightly underbake the cookies to ensure soft results. Or you can pop a few in the microwave for a quick blitz to get the cookies warm and the chocolate chunks melty.

And if they’re still not soft enough, you can dunk them in a glass of milk or a cup of coffee. I tried every which way to enjoy these cookies. They’re well worth the pain and effort.

Chocolate Chunk Oatmeal Cookies

This is my second time participating in The Great Food Blogger Cookie Swap.  I love the surprise and anticipation of getting cookies in the mail.

This year, I sent out my chocolate chunk oatmeal cookies to Trang of Wild Wild Whisk, Corinne of Reverberations, and Samantha of Haute Pepper Bites. In exchange, I received chocolate crinkle cookies from Jennifer of Girl on the Range, peanut butter reindeer cookies from Nina of Crazy For Cookies and More, and jolly jam jams from Matt of Kitchen Man Cooks. Looking forward to next year’s swap!

i had invisalign a couple years ago and was surprised at how painful it was every time i had to switch trays- how can plastic cause so much discomfort?!? hopefully it’s relatively easy for you and you can eat as many cookies as possible! (: i love oatmeal cookies, and find that their chewy, hearty qualities are perfect (not to mention that people tend to ignore them, so more for me!).

    I had braces before and I don’t remember it hurting this much. I think my teeth just felt more secure with the wires holding them in place. lol

    I totally agree! Oatmeal cookies often get overlooked, but I absolutely love them!


Great classic cookie, great flavors and textures.

I did not see the temperature to cook the cookies in the oven??

    Maryanne Cabrera

    Hi Claire! Thanks for letting me know. I updated the directions. It’s 350 degrees F.

Claire VK

Thanks for clarifying the cooking temperature. I did make them and cooked them at 350 degrees. I was wondering if you flattened them before baking or left them round from the ice cream scoop. I am new to your web-site, but I am enjoying your recipes. Made your granola, yum… and making your purple cauliflower tonight!
