This is NOT your average chocolate chip oatmeal cookie. They are hands down the best Chewy Chocolate Chip Oatmeal Cookies. Bar None.

Chewy Chocolate Chip Oatmeal Cookies
I’m pretty sure this recipe is where the phrase, “Bet you can’t eat just one” came from. The recipe I’m sharing here is slightly adapted from and with thanks to Melissa Stadler. The original cookies are called I Want to Marry You Cookies while I can’t guarantee marriage proposals, these are certain to get rave reviews!
When making these I stayed as close to the original recipe as possible, in an effort to see what the fuss is all about. The thing that sets these cookies apart from every other chocolate chip cookie I’ve made is the melted butter.
Such a small thing, but it has an enormous impact on the flavor. The best part of making these? Everything happens in a single pot. Easy cleanup makes this girl very happy.
I feel like I should clarify that these are chocolate chip cookies with oatmeal, a different kind of cookie from these classic Oatmeal Chocolate Chip Cookies. The oatmeal flavor in these cookies is very very subtle.
I shared these with a self-proclaimed oatmeal hater years ago and he reluctantly agreed that while he still HATES oatmeal, these cookies are delicious, and “the oatmeal doesn’t ruin them.” That’s a WIN, my friends!
How to Make Chocolate Chip Cookies Chewy
The warm butter is blended together with the sugars and it creates a rich toffee flavor that I have never before tasted in a chocolate chip cookie. The cookies positively melt in your mouth.
I will caution you not to skip the step of chilling the cookie dough before adding the chocolate chips. If you add the chocolate too soon, it will melt into the dough, leaving you with cookies that are tasty, but nothing at all like the original.
This is the BEST second-day cookie I have ever made. They taste phenomenal warm from the oven and they taste even better the next day. I froze several of them to see how they would handle it and they were excellent as soon as they thawed.
I’m not going to bother saying that these are the best chocolate chip cookies in the world, because everyone has their own opinion on what that would be. However, these are truly some of the best cookies that I have ever made. I can hardly wait to try a whole wheat variation.

INGREDIENT LIST
- butter
- dark brown sugar
- granulated sugar
- egg
- egg yolk
- vanilla
- all-purpose flour
- old-fashioned rolled oats
- baking soda
- kosher salt
- cinnamon
- semi-sweet chocolate chips
Chocolate Chip Cookies with Oatmeal
- In a large saucepan (I used a 6 quart pot), melt the butter over medium heat. Once the butter is melted, remove from the heat and add the sugars. Stir until the sugars are well-incorporated and mostly smooth. Chill the mixture in the refrigerator for 10 minutes.
- While the mixture is chilling, mix together the dry ingredients and set aside. Remove the pot from the refrigerator and stir in the egg, egg yolk and vanilla. Add the dry ingredients and stir to combine. Add the chocolate chips and use your hands to make sure they are evenly distributed.
- Roll by hand into 24 medium size balls or 50-60 smaller ones. Chill for at least 30 minutes. (I simply rolled them into balls and placed them on a couple of plates. Then I stacked the plates in the fridge until I was ready to bake them.)
- Preheat the oven to 325°F. Remove the cookie dough balls from the refrigerator and place them onto a large baking sheet a dozen at a time. Bake for 10-12 minutes, larger cookies will require an extra minute or two in the oven. Remove from the baking sheet immediately and cool on a wire rack.

Wow, that is very interesting that the recipe uses melted butter…I am so curious to see what that does to the texture/taste. I wonder what would happen if you browned the butter..Ok, these are on my list!
Makes for a chewier cookie
Ok.. now that is a statement about a cookie!! Must try these soon 🙂
A marriage proposal to a cookie – its the first time I am seeing this, the cookies must be super special. I will definitely try this recipe. Unique recipe since it contains rolled oats. ANZAC cookies are made with melted butter and its so much easier to work with.
Oh yum, I love the idea of the butter and sugar getting all toffee like together. I'm a big oat fan as well, I think I'm intrigued enough to put aside my own trusted choc chip recipe and give these a go!
Oh …. If I could only eat sugar again. Those look wonderful.
I miss eating sugar..but one little bit spikes my bs so much and I just can't do it.
Try Xylitol. Natural sugar alternative that has no impact whatsoever on the blood sugar or insulin system.
They sound amazing, I actually use melted butter in my cc cookies, but not warm. I am definitely going to try adding the sugar into the hot butter and then cooling it. Great recipe!!!
Definitely going to be making these for Ben!
I don't like chocolate chip cookies, because I like my chocolate alone. And I hate making cookies, because it's so hard to make enough for my hungry horde. But these sound like really great cookies anyway, so I might try them at some point when relatively few people are around, so they'd last more than 7 minutes.
When you put it like that, how can I not make these?
Mmm, I make a very similar cookie with milk chocolate chips from the recipe on the back of the Chipits bag 🙂 The melted butter and brown sugar make for an amazing flavor and chewy cookie!
Melting seems a lot easier than creaming the butter and sugar anyways…well we know what I am doing before class tomorrow!
This is a very different type of chocolate chip cookie recipe. I was surprised to see the little bit of cinnamon in the recipe. It sounds delicious.
I need to try these! You can't beat good cookies!
Cookies look good. Congrats on winning the Girard's dressing.
Hey Mary, I have just updated the traditional steamed cake post with the steps on how to line a tray and steam the cake, you may check out later and hope you will try it out soon. By the way, this is a great cookies!
Love to have a great cookie recipe – I'm not sure these would last till the next day they looks SO good!
Mary x
These sound fabulous. I might have to try them!
I have seen versions of this cookie before… The melted butter is right up my ally since I seem to NEVER have room temp butter ready when I want to make cookies. I really need to give it a try. My husband is the ultimate cookie critic. So I'll have to see what he says.
A friend of mine won the county fair cookie contest a couple of years ago using a recipe very similar to this. Her secret? Brown, melted butter.
Yes! A chocolate chip cookie with oatmeal recipe that calls for melted butter! My joy is complete! CANNOT wait to try these….as soon I get off work, work out, eat dinner…adding make these cookies to my list : ) I might even be tempted to grind the oats up before I put them in…hum, maybe? Thanks Mary!
In the 80's there was a choc chip recipe going around that was supposed to have cost $250 dollars because it was from Nordstroms. The lady paid the money and freely passed out the recipe to everyone and anyone because she was mad they charged her for it. It had ground oats in it and it was very yummy!
I have that recipe!!!! It's very good!!! It's called $250 cookie too!!!
