Chewy Black + White Chip Oatmeal Sandwich Cookies.
I like sandwiches. And I like cookies.
However, would I like sandwiches in my cookies or cookies in my sandwiches? The latter… probably yes.
While most of my favorite sandwiches consist of some sort of crunchy bacon and toast and aioli and poached eggs, I wasn’t sure how well that would pair with a cookie. You know. You get it.
Hence the buttercream filling. Wait. The MARSHMALLOW buttercream filling.
Oh don’t get too excited. It’s just butter, marshmallow fluff (real or store bought works) and sugar. Fancy fancy. But not at all.
Guess what? It’s exactly one week until Christmas and I haven’t baked a thing yet. Well, besides these. Like they would even last a week. I have a list to get through people. I’m starting today.
That’s a lie. I’ll probably start on Saturday at midnight.
I’ll blast Mariah Carey, Barry Manilow, N*SYNC and maybe Lady Antebellum Christmas music. With a hint of Ariana Grande santa baby. I sort of have holiday iTunes ADD.
I’m copping out today like I do every now and then and using this chewy oatmeal chocolate chip recipe from a few years ago. I absolutely adore it and it’s one cookie I make constantly, regardless of how many new recipes need to come out of my kitchen. This time though, I swapped the baking powder for baking soda (accidentally on purpose, but not really. How does one go to the store every single day, sometimes multiple times per day, and still forget things?) resulting in a slightly thinner cookie but a chewy one nonetheless.
Ohmahgah. I can’t even stand the chewiness. It’s so ridiculously fabulous.
These cookies are thin and a bit crisp, but still packed with some chew. It’s like my dream is a little baked dough ball.
I’d like to faceplant into the center of these sandwiches and get stuck there for the next few days. Figuratively speaking, of course. I’m probably one of the only ones in the universe, but I LOVE this crazy time of year. I adore the hustle and bustle. I love going shopping or heck, just going to the mall and watching others shop. This season does not stress me out nor do I wish it away. I live for it. Crazy?
Maybe one day if I have some kids that will change, but I’m hoping not. It’s so fun. ‘Tis the season to wear glittery eye shadow, sparkles on your face and sequins on, well, everything. ‘Tis the season to stuff your face with cookies for breakfast and then go for a run.
Seriously the best time of year.
Chewy Black + White Chip Oatmeal Sandwich Cookies with Marshmallow Buttercream Filling
Ingredients
- 1/2 cup unsalted butter, at room temperature
- 1/2 cup sugar
- 1/2 cup loosely packed brown sugar
- 1 large egg
- 2 teaspoons vanilla extract
- 1 1/4 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 3/4 cups rolled oats
- optional: 1-2 tablespoons milk, if dough is super crumbly
- 2/3 cup dark chocolate chips
- 2/3 cup white chocolate chips
marshmallow buttercream filling
- 1/2 cup unsalted butter, softened
- 1 cup marshmallow cream, homemade or store-bought is fine
- 1/2 cup powdered sugar
- 1 teaspoon vanilla extract
- 1 pinch of salt
Instructions
- Preheat the oven to 375 degrees F.
- Add the butter to the bowl of your electric mixer and beat until creamy. Add in the sugars and beat on high speed until fluffy, about 2 to 3 minutes. Add the egg and vanilla, mixing well until combined, about 2 minutes. Stir in the flour, baking soda and salt with the mixer on medium speed. Beat in oats until just combined. Add in 1 tablespoon milk if the dough appears too crumbly. Fold in the chocolate chips. Refrigerate the dough for 30 minutes.

A cookie cannonball into the center would be ideal.

I totally love this time of year too! I also love these cookies. Marshmallow, butter cream, oatmeal, chewy AND crunchy?…I just died.
I think you have the right idea with all the Christmas chaos – it’s easy to fall into the camp of people who hate it, but why do that?! It’s only for a few weeks – and it’s only once a year!
I say bring on the hectic and the hustle/bustle…and while you’re at it…bring on these cookies.
Ok, I’ve said it before that I’m not normally into sweets and crave a lot more of the savoury types of foods, but you have got me SERIOUSLY wanting some of these right now! Can I just stay home from work and bake all day? ;)
I am so appreciative of cookie recipes this time of year. We’re planning a day of baking at my parents’ house on saturday and I’ve wanted to make something new and different to share this year. I had planned to make a bunch of dough ahead of time and bake when I get there, but I might whip some up the day before so I can nibble alone… He he :)
I love this time of year too! I look forward to going out and dealing with the traffic and the amount of people, it’s just so exciting!
A cookie sandwich, yes!! These look amazing, that marshmallow buttercream sounds divine!
First you take the mallow…then you turn it into buttercream and stuff it into a cookie. That’s how that sentence ends, right?
I ridiculously love the marshmallow filling. I am a big fan and have used in in numerous recipes, i filled iced vovo macarons with it a few weeks ago. SO creamy and delicious! It is the perfect cookie filling.
Marshmallow Butter Cream?! How great is that! I love this time of year too!
Mallow frosting? I want a bowl and a spoon. Though sandwiched between oatmeal cookies is great too ;)
I really want to eat the marshmallow buttercream by the spoonful! And these cookies look so chewy! Just absolutely the perfect stuffing vehicles for copious amounts of the marshmallow buttercream! I love oatmeal cookies and would probably take them over choc chip, even – so I know I need these sandwiches! Good luck w/ your bake-athon!
The best time of year is right. :) Now, cookie-sandwich me.
Ummmmmm… girl, these look DAMN GOOD!
Wishing you a very Merry Christmas… hope it’s filled with wonderful food and drink and good company.
Don’t worry, i haven’t started baking yet either. But I have started recipe development work for Valentine’s Day. Weird, I know.
I want 100 of these sandwiches delivered to my gingerbread house, please.
I just made cookies last night for a work cookie exchange, but other than that I’m totally behind on the holiday baking! Tonight or tomorrow I’ll probably start the cookies to give to neighbors!
Can I just eat the buttercream filling? If that’s wrong, I don’t want to be right!
These are some pretty perfect looking cookies. Ooooh, I’m also imagining them with all sorts of buttercream now too. Like maple! YUM!
I second the faceplanting into these cookies. They look fabulous!
These are simply gorgeous! They’d last in my apartment about an hour.
I can already feel my sugar crash! These look worth it though!
I’m rather impressed by your cookie stacking skills:)
I like sandwiches and cookies too!! TOGETHER FOREVER!
okay YUM these look amazing. they’re going on my holiday cookie-baking list ASAP!
FREEZE THESE. then eat them. then die of happiness. the end. xxxx
I make oatmeal cookies using white and dark chocolate chips all the time – it’s the best! I’ll definitely need to try the cookie sandwich though. Or maybe put some ice cream in the middle of these bad boys.
sign me up for ANYTHING with marshmallow fluff!!!
Super yum to these cookies Jessica, I could eat a couple for sure!
I think I just died and went to cookie heaven! I love the combination of oatmeal, chocolate and marshmallow buttercream.
Not kidding when I say I love everything about this! UGH.
I’m just glad these cookies just look like cookies. Whew!
And on another note…I’ve been making a chocolate chip oatmeal cookie for years that was my Grandma’s recipe…I can almost taste it with this twist on buttercream but I will be coming to your house to try them.
There is no Christmas here, no tree, no music, no joy…nuttin honey. If I miss escaping from here and getting in my home before Christmas than I am officially declaring it a two month event for January will be mine to celebrate. Wanna join me? I’ll have a tree to decorate, cookies to make and yes, shopping to do. You would be the perfect partner in crime!
cooooooookkkkiiessss…
Gah, I want this SO bad…but you KNOW its just because I want to lick all that icing off! Yummmmm
I love all the Christmas shoppers too. It funny to go to Target and see people wildly throwing things in their carts for gifts because they have no clue what to get someone…and I would be nice and tell them that Aunt Sally really won’t want those weird creepy socks…but its more fun to watch then to speak up in a moment like that ;)
Wow these look beautiful and delish, I love me some oatmeal cookies!
My Uncle Luke recently got Mercedes M-Class Diesel by part-time working online at home… go to this web-site…xurl.es/q8kzy
