Homemade Oatmeal + Marshmallow Creme Pies

by Amy on 18 October 2012

y’all, i am so excited to share these cookies with you! as i’ve mentioned before, i’m not the hugest sweets fan – most times, i prefer something savory or salty over a sweet. these homemade oatmeal + marshmallow creme pies, though, brought out a crazy, sweets-lovin’ maniac in me. and everyone i shared them with, now that i think about it. =) they’re incredibly decadent + absolutely wonderful.

the oatmeal cookies themselves are perfect – buttery + soft, with just the slightest hint of crispiness around the edges. they are fantastic just on their own – they’ll be my go-to oatmeal cookie recipe from now on – but they’re even better made into sandwiches with marshmallow buttercream. the marshmallow filling is on the sweeter side, which complements the rich, less-sweet oatmeal cookies in a glorious way. after i made these, i made myself give most of ’em away because i feared i couldn’t resist eating them in massive quantities. that’s how amazing these are – you gotta try ’em!

homemade oatmeal + marshmallow creme pies

makes about 20 cookie sandwiches, adapted from bakingdom


for the cookies:
1 cup unsalted butter, room temperature
1 cup brown sugar
1/2 cup granulated white sugar
2 eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon cinnamon
1 teaspoon baking soda
1/2 teaspoon salt
3 cups quick-cooking oats

for the marshmallow creme filling:
6 tablespoons unsalted butter, room temperature
1 cup confectioners’ sugar
3/4 teaspoon vanilla
pinch salt
1 1/4 cups marshmallow creme


first, make the cookies:
preheat oven to 350 degrees. line baking sheet with silpat mats or parchment paper.

in a large bowl, or the bowl of a standing mixer, cream the butter for about 30 seconds, then add both sugars + beat until light + fluffy. add the eggs + vanilla, mix well, + scrape down the sides of the bowl as needed.

in a medium bowl, combine the flour, cinnamon, baking soda, + salt. add the flour to the butter mixture in 3 increments until just combined. stir in the oats until evenly distributed.

drop 2 tablespoons of dough (about the size of a golf ball) onto the pan at a time, about 2 inches apart. bake for 10-12 minutes, until golden. allow to cool on the baking sheet for 2 minutes before transferring to a cooling rack. cool completely before filling with the marshmallow creme.

to make the filling:
in a medium bowl, or a stand mixer fitted with the paddle attachment, cream the butter + sugar together until light + fluffy. add in the vanilla + a pinch of salt. mix in the marshmallow creme + beat until light + fluffy. cover bowl with plastic wrap + chill for 30 minutes. if filling appears too soft, add more sugar as needed (amy’s note: 1 cup of confectioner’s sugar worked perfectly for me)

assemble the sandwiches: place 1 – 2 tablespoons of filling on the bottom of a cookie, then place another cookie, bottom side down, on top. continue until all cookie sandwiches are made.

These look so yummy! They remind me of a packaged treat I used to beg for at the grocery store as a kid. These look much better though!

2 amy October 18, 2012 at 6:10 am

Yes! they’re just like the Little Debbie store-bought version … only tons better + with less preservatives/fake stuff. =)

3 Maggie @ A Bitchin' Kitchen October 18, 2012 at 6:18 am

These look so good! Oatmeal cookies are one of my faves!

4 Beth October 18, 2012 at 6:47 am

They look absolutely adorable. (And I’m sure they taste wonderful too!) As someone who really does love sweets, I don’t think I could resist them.

And I know exactly what it’s like to give food away so I won’t eat it all myself!

5 Rachel Cooks October 18, 2012 at 6:55 am

Oh yummy! These look perfect!

6 danielle October 18, 2012 at 6:58 am

These look great! Oatmeal cookies are my favorite – way to kick it up!

7 Tara @ Chip Chip Hooray October 18, 2012 at 7:32 am

Yum! These definitely were one of the treats my mom wouldn’t buy me in the grocery store when I was little. :)

8 amy October 18, 2012 at 7:56 am

I totally hear ya – we weren’t allowed to get them at the store either because they weren’t healthy enough!

9 Rachel @ Baked by Rachel October 18, 2012 at 8:07 am

Soft cookies with marshmallow buttercream filling?! I am SO in.

10 Jocelyn @ BruCrew Life October 18, 2012 at 8:52 am

Oatmeal cream pies are my absolute favorite little debbie…preservatives and all:-) I do love that these are a much healthier version for me to feed my kids!!!

11 Jen @JuanitasCocina October 18, 2012 at 9:03 am

I’ve been dreaming about these ever since I saw your teaser! Gorgeous!

12 Monet October 18, 2012 at 9:11 am

Oh love they look just perfect! I could probably eat at least a dozen. Thank you for sharing. These are going to be made very very soon!

13 Kathryn October 18, 2012 at 9:59 am

These look absolutely perfect, I just love the idea of that sticky sweet filling and the oatmeal cookies.

14 Hayley @ The Domestic Rebel October 18, 2012 at 10:06 am

Oatmeal creme pies are my liiiiiifeeeee. I love those little things. And these look totally phenom, Amy! The oatmeal cookies on their own look so totally perfect, and the marshmallow filling looks so fluffy, I don’t know how you didn’t stick your face in the bowl and eat it straight.

15 amy October 18, 2012 at 10:28 am

Oh, I did! I ate waaaay more of that marshmallow filling straight outta the bowl than i’d like to admit… =)

16 baker street October 18, 2012 at 11:01 am

I have one question – how did you manage to take pictures?! this wouldn’t make it out of the kitchen in my house. heh. absolutely delicious, amy! :)

17 amy October 18, 2012 at 11:39 am

bahaha! good question. i did sample quite a few before i managed to get ’em staged + photographed!

18 Ashley Bee October 18, 2012 at 11:45 am

I don’t like oatmeal cookies, but I LOVE marshmallow so I think I could make an exception for these :)

19 Nik@ABrownTable October 18, 2012 at 12:02 pm

These cookies look divine!

20 natalie@thesweetslife October 18, 2012 at 12:26 pm

i wish i were less of a sweets fan!! :) i always use old-fashioned oats in cookies and i love their texture but if these are your favorite ever, maybe i need to try quick oats sometime!

21 amy October 18, 2012 at 12:27 pm

you should definitely try these sometime, natalie – it really is my favorite oatmeal recipe cookie to date!

22 Jackie @ The Beeroness October 18, 2012 at 12:28 pm

This look amazing! They totally remind me of a grown up version of those Little Debbie oatmeal cream pies I loved as a kid. These look so much better, great job!

23 Nicole @ The Marvelous Misadventures of a Foodie October 18, 2012 at 12:33 pm

My hubby would love these, he always begs me to buy those nasty packaged ones at the grocery store haha. These would totally win in a face off 😉

24 Erin @ Texanerin Baking October 18, 2012 at 2:29 pm

They’re so cute! These are the perfect creme pie cookies. I always try using random cookie recipes and they come out as failures. Oh well. At least I can try these!

25 Lesley Eats October 18, 2012 at 3:02 pm

Oh, yum! Much better alternative to the ones I grew up eating. :)

26 Chandra@The Plaid and Paisley Kitchen October 18, 2012 at 5:39 pm

Oh these are like my most favorite of the little debbie snacks! I think that I am going to have to give these a whirl!

27 Ashley @ Kitchen Meets Girl October 18, 2012 at 6:16 pm

Oatmeal cookies are my fave–and the creme pies were always my fave of all the Little Debbies. These look perfect, Amy!

28 Kristen @ notsodomesticated October 18, 2012 at 6:51 pm

Oh boy, these bring back memories! When I was in college, I ate super healthy the majority of the time, but my roommate didn’t. And she would always buy those Little Debbie Oatmeal Pie snack cakes. So when she was gone for a weekend and I had a sweet craving, I would end up eating half the box haha! So then I’d have to go out and buy her more. It was a vicious cycle. Needless to say, I love oatmeal cookie pies … and these look incredible!

29 amy October 18, 2012 at 7:05 pm

bahaha, that’s awesome! i was definitely guilty of snacking on my roommates’ unhealthy snacks when they were out of town, too. too funny!

30 The Squishy Monster October 18, 2012 at 7:07 pm

YUM! This certainly takes me back to my childhood =)

31 Brittany October 18, 2012 at 7:38 pm

I would be excited for this recipe too!! These creme pies look soooo fresh and fluffy!

32 luv what you do October 18, 2012 at 7:39 pm

Wow! Those are beautiful! I love anything with marshmellow…especially fluff!

33 Chung-Ah | Damn Delicious October 18, 2012 at 7:49 pm

I’m not much of a sweets fan but I can definitely get on board with these! That marshmallow creaminess is so inviting! I just want to eat it with a spoon!

34 Julie @ Table for Two October 18, 2012 at 8:47 pm

these look so heavenly and fluffy! this brings me back to those little debbie ones – but obviously yours is better cause it’s homemade with love :)

35 amy October 18, 2012 at 9:13 pm

aww, i love the way you phrased that. they *are* homemade with love!

36 Choc Chip Uru October 19, 2012 at 1:05 am

Oh wow since it has oatmeal I think this is fine for breakfast right?

37 Jen @ Savory Simple October 19, 2012 at 6:57 am

I looooved oatmeal cream pies when I was growing up. I’ve always wanted to make them from scratch!

38 amy October 19, 2012 at 7:35 am

ha, i love the way you think! yes, i think these are an acceptable breakfast. =)

39 Sandra's Easy Cooking October 19, 2012 at 10:22 am

I am def. more into savory than sweet, but then when the craving hits I need sweet asap:)
These cream pies looks delicious and very tempting, Amy!

40 CJ at Food Stories October 19, 2012 at 11:44 am

I recently made some cookies similar to this and I can’t stop eating them … Yours look fabulous :-)

41 Marta @ What should I eat for breakfast today October 19, 2012 at 12:54 pm

They look so cute, perfect as an addition to a tea for a cold winter mornings.

42 amy October 19, 2012 at 1:28 pm

i loved these with a cup of hot tea for my afternoon snack, so i like the way you think!

43 Nicole @ Lapetitebaker October 19, 2012 at 2:25 pm

I could not be trusted with these in my kitchen either! Creme pies are my weakness.

44 Anna @ Hidden Ponies October 19, 2012 at 10:09 pm

These look amazing!! I adore a good basic oatmeal oatmeal cookie, and sandwiching them just sounds perfect!

45 Regina @ SpecialtyCakeCreations October 20, 2012 at 2:34 am

Oatmeal cookies are definitely one of my favorites. But who am I kidding, there are not many cookies I will pass up. And my husband is the same. I might have to use your giving away approach in the future, if any make it to that stage.

46 Renee October 20, 2012 at 6:52 am

And i just bought some oatmeal. all i need is the marshmallow cream and I’ve got everything to make these fantastically yummy looking cookies. if not now, then for christmas cookies for sure.

47 amy October 20, 2012 at 8:28 am

Hope you love ’em when you try ’em! =)

48 Jed Gray (sportsglutton) October 20, 2012 at 2:16 pm

hmmmm. Let me see, I love just about anything with oatmeal cookies so you don’t have to tempt me even once to eat these. Looks soooo tasty Amy!

49 amy October 20, 2012 at 5:05 pm

you are an oatmeal cookie connoisseur for sure, so i’m glad these get your stamp of approval! =)

50 Sarah K. @ The Pajama Chef October 20, 2012 at 6:11 pm

i must say… these look good for what they are. i OD’d on oatmeal creme pies when i was a kid and have been turned off to them ever since, but these are pretty :)
