Oatmeal Chocolate Chunk Cookies

Oatmeal Chocolate Chunk Cookies with Cinnamon Buttercream | Cookies and Cups

These Oatmeal Chocolate Chunk Cookies are based on the popular Ben & Jerry’s ice cream flavor! They’re a thick oatmeal cookie loaded with chocolate and topped with a creamy sweet brown sugar cinnamon buttercream!!

I’m not sure if the ice cream flavor is available everywhere, but it’s a HUGE favorite of mine! The ice cream itself is Sweet Cream Cinnamon Ice Cream with Chunks of Oatmeal Cookie and Fudge. So making a cookie version was kinda easy and totally delicious.

You can absolutely make these Oatmeal Chocolate Chunk Cookies without the frosting, but keeping in part with the ice cream flavor it’s a fun addition!Oatmeal Chocolate Chunk Cookies with Cinnamon Buttercream | Cookies and Cups
Chocolate Chunk Oatmeal Cookies are easy! They’re thick and soft with crisp, buttery edges! It’s a fairly straightforward recipe. But I do use only dark brown sugar in my oatmeal cookies. The dark brown sugar gives the cookies a deep, rich flavor. If you have made my Oatmeal Raisin Cookies, you know what I mean…and if you haven’t, you NEED to!!

Also I used quick oats in these cookies as opposed to rolled oats, or old fashioned.

The quick oats are cut into small pieces (so they cook faster) and tend to give this cookie a more uniformed texture. You could certainly sub in rolled or old fashioned if that’s what you have, it isn’t going to hurt, the cookies will just appear more “oatey”, which is totally a word.

Let the cookies bake until they are golden around the edges…don’t over-bake these guys.
Let them cool on your baking sheet for about 3 minutes and the transfer them over to a wire rack to finish cooling.

While you’re waiting you should make your frosting.
Now this frosting is out of control good. Like I said earlier, it’s a Brown Sugar Cinnamon Buttercream, so it’s pretty much perfect.

Just beat some butter and brown sugar together (again, I used dark, but that’s a personal preference) and add in some cinnamon…

I like using a strong Saigon Cinnamon. It just tends to have a bit more pop of flavor.

Whip that up with some powdered sugar and milk and you’ve got it! Give each cookie a healthy dose of frosting and you’re all set…

My cookies didn’t flatten out like your picture…? I used my small cookie scoop. I forgot to use my dark brown sugar but will next time, along with my bigger cookie scoop. Will the frosting lose the crunch crunch from the brown sugar if I cream it longer?

Is there no baking powder or baking soda in the recipe? I didn’t see it in the ingredient list. Thank you for the recipe!

The cookies are the BEST!!! My husband says they are the best he has ever had. Thank you for the recipe! I need to make a ton of these for a function (dozens and dozens). Would you recommend freezing them with the frosting ON them? Or frost them after defrosting?

Hi Shelly

How would stack or store these cookies to keep the frosting on them, if you want to give these as gifts.

Made these a couple days ago and my family and I love them. They’re super moist and the cinnamon buttercream frosting adds the perfect touch!

The batter for these cookies was delicious, however, the frosting was way too sweet! I regret not tasting it after each cup of powdered sugar was added. 🙁

Was craving something sweet and I came across this recipe. Amazing!! They were so quick and easy to make, and that frosting was an amazing touch! So yum. I halved all the ingredients for the frosting as I only baked half a batch of cookies (froze the other half for later) and it was still really good. Yum yum yum.

Just made these and they are so good! Didn’t make the icing tho as I only have one mixing bowl and I still have dough in it. So I made a glaze from icing sugar, cinnamon, milk and vanilla instead. Too hot to add it still but tastes good. Thanks for a yummy recipe!

I just made these cookies and they’re absolutely delicious! I just wondered. I made half of the frosting, because some people here don’t love frosting (can you believe that?), but I still had way to much frosting for all my cookies. So I ended up throwing some frosting away. How much frosting do you put on your cookies? I think it should be quite a lot or did I something wrong that I had to much frosting?

OMG! These look so delish! I love the addition of the frosting!!!
