Oatmeal Chocolate Chunk Cookies

Oatmeal Chocolate Chunk Cookies with Cinnamon Buttercream | Cookies and Cups

Ben and Jerry’s week is winding down…
So far we’ve hit on Cherry Garcia, Phish Food, What a Cluster, Everything But the…, Everything But The (again), Americone Dream and Karamel Sutra.

Hasn’t it been fun?


Today, the final day (sob), I’m taking Oatmeal Chunk Cookie here, Kristan is doing Chunky Monkey, Peabody is doing Heath Bar Coffee Crunch and Heather is joining us and taking on Chocolate Therapy!


I have to say there are SO many other flavors that are worth playing with, I can see a sequel somewhere in the future!


Anyhow, Oatmeal Cookie Chunk was an easy choice. The Ben and Jerry’s flavor is Sweet Cream Cinnamon Ice Cream with Chunks of Oatmeal Cookie and Fudge.

So what I did was kinda easy and totally delicious.
I made some super yummy Oatmeal Chocolate Chunk Cookies and topped them off with a Sweet Brown Sugar Cinnamon Buttercream. Seriously, a perfect cookie.

I made the oatmeal cookies first.

It’s a fairly straightforward recipe. But I do use only dark brown sugar in my oatmeal cookies. It’s my thang.

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…

Honestly, these are going in the cookie rotation in my house!

Ben and Jerry's Week!

Now you NEED to go hop over and see what Kristan did with Chunk Monkey.

Also, Heather from Sprinkle Bakes joined in today and took on Chocolate Therapy and I can’t even stand it, quite honestly!

 AND Peabody joined us for all 3 days!  And today she made cookies.  Coffee Heath Bar Crunch Cookies.  Yep, for real!

  1. I’m sitting here with my jaw to the ground because a) I had no idea that Ben and Jerry’s has an oatmeal cookie ice cream – I feel cheated (I do live in the middle of nowhere with unspeakable, meaning terrible, grocery access, but still) b) I’ve never thought to put frosting on top of an oatmeal cookie but clearly I need to rectify that immediately and c) I just spent the last hour perusing the internet for a dessert to make for a ladies’ night dinner at my house tomorrow – I was feeling oh-so uninspired (how does that happen with so much available on the ol’ internet anyway) and then I saw these which of course I’ll be making. I don’t know how you come up with this stuff but you are brilliant.

    I made these cookies last night for my husband…. needless to say, I am the best wife in the world. Really. These are AWESOME!!! Great job!!!

    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?

  4. 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!

    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.

  6. Krissy

    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. 🙁

  7. Jayla

    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!

      I would let them sit out for a few hours for the frosting to set up. It’s a fluffier frosting so it will never set up completely. But I night recommend laying them sideways in a box and using parchment paper to separate them.

  8. Megan

    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?
