Chocolate Whoopie Pies with Cake Batter Buttercream

So I was thinking the other day…how weird are mustaches?

Like, they are so weird.

I am allowed to talk about this because my dad has a mustache and has had it for as long as I have known him…and from what I understand, many years before that  too.

What I find weird is when guys my own age decide to grow one.

I saw a gentleman the other day (who has a perfectly fine face) with the beginnings of a mustache.  Not a few days without a shave.  A very deliberate mustache.

And I can’t help but wonder what could have led up to that decision.

Maybe he woke up one day and decided that the space between his upper lip and nose was too big and needed to be filled with hair.  Or maybe he saw his picture in a profile and thought…I didn’t know my nose was that big, maybe I should fill in the space with some hair and have it appear smaller.  Like an optical illusion.  Or maybe he had a really sweet gold chain he wanted to wear that didn’t look quite right without a mustache.  Or MAYBE he saw one of the TV movies Jesse Stone on CBS and recognized how attractive Tom Selleck is and wanted to get in on the action.  Like that episode of Friends where Chandler tries to grow the mustache to look like Richard..remember that?  Yes, Tom Selleck has that power.

I know the ‘stache was a trend in the 70’s and 80’s…and I think if you grew one back in the day and stuck to it (like my dad and Mr. Selleck) you are allowed.  But if you were just a babe when the trend was in full force, there is no reason to try and bring it back.  All the hipsters that grow them ironically…stop it.  Just stop.  In my opinion, leave the mustache growing to professionals.

Here’s my dad and I in January.    See this is how you pull off the non-creepy ‘stache…It’s really an odd thing if you think about it.  So I decided that I would google “who invented the mustache”.  I have to say I was quite horrified with some of my findings.  And as it turns out no one really knows, so save yourself the time…

It’s just really arbitrary, don’t you think?  I wonder if I grew a random patch of hair on my legs if it would take off as a trend?  I mean don’t you remember in the 90’s when men tried to make the “soul patch” happen?  It makes no sense.

So lesson of the day..unless you are my dad or Tom Selleck please stop intentionally making yourself look like  a pedophile.  Because that’s what we all think.

I love you dad.

Now, if you haven’t completely lost your appetite, let’s move on to over-the-top deliciousness.

The Whoopie Pie.  It’s not a new invention, but I decided to give it a go with some yummy filling.  Cake Batter filling.  What’s that you say?  Oh yes..I HAVE lost my mind.

First you have to make your cookies.

It’s a pretty easy recipe.  Mix your butter, sugar..blah blah blah…

Then add your dry ingredients.

Then the milk…

Now you have batter.

Now bake.  Bake I say!

The will come out nice and pretty.

and ready to be filled with amazing cake batter frosting.

Leave a little squish room around the edges..

And I rolled my pies in sprinkles, just because it seemed like the right thing to do.

My dad had a mustache until I was around 7 years old. I remember being so mad at him when he shaved it off, he wasn’t my dad anymore!!

P.S. I LOVE all the pictures you have on your blog. Do you have a special place in your house to take these photos? What is the green background?


Do I need to use shortening…. I hate using it… how will it affect the recipe if I use all butter? I would need to up the butter though because butter is like 85% fat vs shortenings 100%… Anyways let me know I’d like to give these a go they sound amazing and look oh so cute 🙂

Averie @ Love Veggies and Yoga

Between the chocolate, the sprinkles, and that FILLING…I am drooling!


Yummy!! Thanks for sharing, I love your recipes! I love that you used cake mix for frosting – GENIUS! I will definitely be trying it in the near future 🙂
I, too, am weirded out by mustaches (the oh so popular decorative vinyl/jewelry/etc ones are pretty cute though) – my dad has always had the iconic “handlebar” mustache going on, too. It creeps me out especially when the boys start getting in their teens and decide to grow their first one… just DON’T!! Yikes… 🙂

There is a story of me being about 6 years old…stumbled upon my father…shaving his beard and stash off(this is 1986 mind you)….and when I realized it was going to be completly gone, apparently I lost my friggen mind on him. I didn’t recognize him as my dad with out all the fuzz!!! ANyway….Im in love…if it wasn’t unspeakable hot and humid in my house right now(thank you 1970’s era apartment house hell) I’d totally get ready to bust these out! Oh and I need the cake mix…normally using cake mix would be grounds for time out in my house… Read more »

Some things in life just deserve a jaw-dropping stare- and this is one if them! Love the recipe and love the pics 🙂

Okay i so am going to try the cakemix in the frosting. I am not a buttercream frosting fan but this sounds incredible. i have used powdered cake mix in making rice krispie treats and it gave it a very unique flavor for rice krispie treats. thank you

Get out! Cake batter buttercream! You rock!
OMG! I have a family full of men who look like pedophiles!! o.O Although, I do have one Uncle that looks a lot like Tom Selleck so I guess that evens things out. LOL


Wow this sounds amazing! And great photos! What does the buttercream taste like? I’m considering making it for cupcakes I have to do soon, but I have no idea how it would come out. How does it differ from regular buttercream?


I cant wait to bake these up!


HAHA! I was just having a conversation with my son and his dad today about mustaches. I am with you 100% but they think I am crazy 😛

Amy | She Wears Many Hats

So cute!

The mustache on your dad too. ; )


Aww, those are so sweet! Love the sprinkles. I am hosting a recipe party at my blog if you might be interested in submitting. I’d love to have you join in the fun 🙂

Robyn | Add a Pinch

Love your dad’s sweatshirt, too!!! I want one of those whoopie pies right about now, please. With a tall glass of milk.

Mustaches on young people basically scream “I am going to try to murder you, or say awkward things that make you uncomfortable”

Unlike these whoopie pies…they just scream happy. 🙂


This sounds delicious…but I gotta say – I love mustaches. I keep trying to talk my husband into one.


My dad has had a mustache for forever also, but on anyone other than him, I think they look either sleazy or creepy…usually both.

cake batter filling…you know your way to my stomach so well…


The Food Network has been the only channel played on my TV since April, and finally this month I’ve decided to start baking & cooking. I just found your food blog a few minutes ago, and from the first words I read, “how weird are mustaches?” has made me want to try all your recipes. Thank you, because I now want to create everything you have put on your site. And because I also wonder why guys decide to get mustaches.HA!


My husband had a goatee for about 10 years – not too long out of highschool and up til last year. Last year he grew it into a full on beard. He keeps it trimmed very short though. I totally think facial hair is sexy. Not just a ‘stache, though. That’s just creepy. Unless it’s on your dad or my dad or someone else who is clearly of the age to be my dad.


Oh my gosh! I could not agree more about the stache! About a month ago, my husband thought it would be funny to shave his face but leave the beginnings of a stache. He couldn’t even keep a straight face long enough for me to believe he was serious! I walked in and he started grinning and I was like WTH? LOL! Not to worry, he shaved it off!


Thin mustaches totally gross me out. Not that I am a fan of thick mustaches much, but they looks less skeevy. Unfortunately my boyfriend likes to sport one once in awhile. Thankfully he can grow a mean mustache, but I still like to call it the molestache because he looks like a creeper. Anywho, these sound amazing!


I love the cake batter buttercream! Ps…I am not even sure I know a young guy with a stache!


lovely cake. love urpost looking for ur visit in my blog

bonnie at sweet life

hubyy had..had a stache..gone, lol

suer cute w pies, love the green backdrop!!


Seriously amazing girl!!


Cake batter buttercream?!?!?!?!?! ooh, I can’t wait to try that!

Mal @ The Chic Geek

Oh wow, these sound amazing! Such a fun idea, love the sprinkles


My dad is another old gent who has been sporting a moustache (and sometimes a beard, but always the moustache) for a very long time. He’s had to shave it off for dares and such (He used to coach track and would shave it if kids would break school records or get to the state meet, etc) and he looked weird and wrong and creeperish. If my husband tried to grow one though, I think I would have to do some serious thinking about our relationship. ;P

These look great! Thanks for another easy and delicious winner!

fiona gamble

What is vegatable shortening and funfetti ?? sorry british girl reading your blog, they look fantastic x


You are a riot! Awesome idea, thanks!

Lauren at Keep It Sweet

Love these, especially the cake batter buttercream! And most people can not pull of mustaches, they shouldn’t even be allowed to try.


omg these look amazing!!! I must try that cake batter buttercream, like right now!!!


My husband tried to grow a mustache once, but it just wouldn’t grow:) My son-in-law, who just turned 30 and is a dentist recently, decided to grow a mustache/goatee because many of his patients come in and ask him if he is in high school…now no one asks:)

Your cake batter buttercream is pure genius, Shelly! I love that top photo too!


How crazy, I JUST made and posted about some fairly traditional whoopie pies but I must say your cake batter filling just sounds better. YOM.
I have to petition to add my dad to the list of people who can pull off a mustache… he is one of those forever ‘stache-wearers and also makes it work. I don’t think I could imagine him without one.

Pedey @ Do You Smell That

THAT was finny!! Thank you for saying what we’re all thinking.

bridget {bake at 350}

Love seeing you and your dad. You’re right…pretty much your dad and Tom Selleck are the only people who can pull off that look.

Cake Batter Filling?!? Shelly….you are baaaad. And I’m so glad to know you! 🙂

Amber | Bluebonnets & Brownies

True Story: My dad had had a mustache my entire life. When I was 10, he shaved it off. My sister and I cried for 3 days because he no longer looked like Daddy. We have issues.

These look amazing!! I agree with the whole mustache point. They are creepy! So creepy in fact that my daughter has a phobia of ALL facial hair. The doctors can’t explain it but shes had it since she was born. My daughter, whos now 8, has never believed in Santa for this very reason. Some breaded man creeping in our house in the middle of the nights…no thanks just leave the presents on the door step. Does it help her phobia that we live in Alaska and the men here think they need to unite and start growing mountain man… Read more »

My dad has always had a mustache. Well he shaved it for a short period of time and that was a big no- no so he grew out a beard and then jsut left a mustache again. all was right in the world then. ha

Where do you get your sprinkles? They are so bright!


I need to submit my mustache picture. I think next to your Dad and Tom Selleck, I might be in the running.

And no I didn’t lose my appetite, those Cakebatter Whoopie Pies look. . . .glorious!


I work in a college athletic dept and during training camp, the football team had ‘Mustache Friday’ and they all grew these gross little mustaches! They all looked incredibly creepy!!

These whoopie pies look awesome!! I just found your blog and I’m already in love!!


Should I refrigerate these after I make them?! Going to make a day ahead of my party!


Can these be frozen, do you know? I would love to make these for my daughter’s baby shower, but I won’t have time the day before…. If not, I guess I’ll be up late the night before!


I came across your mouth-watering blog via Pinterest. So many great recipes I want to try (including this one). As a staunch mustache proponent, it would be remiss if I didn’t courteously disagree with your stance on the mustache. I too admire Tom Selleck as the consummate exemplar of mustache-dom, but I feel strongly that the growing of said facial hair should not be limited to older men and Mr. Selleck. I believe that it’s a look that men of the millennial generation wear just as well as their baby boomer forerunners, your Thomas Magnums and Ron Swansons. I submit… Read more »

Can you freeze these?


I just stumbled onto your blog…and I must say, you are making me laugh and making me hungry at the same time! I LOVE to bake sweets and every recipe that I have read sounds delicious!!


I have these cakes cooling as I type :). I’m going to use another buttercream recipe since I never have box cake mix on hand, but the cakes seem to have a wonderful texture! I have to say though I used ONLY margarine, no butter or shortening in the batter. I don’t use shortening ever, and I figure there’ll be enough butter in the buttercream. Can’t wait to try them!


I like how these are baked just on a cookie sheet – no “whoopie pie” pan needed.

I admit I had not previously read this post – mostly because I started following you in November so I missed it by a few months. But in any case, I MUST agree. My Dad: also rocking the non-creepy ‘stache. Apparently he shaved it off ONCE in all of the time my Mom has known him, and that was when my older sister was 1 year old and she would not go NEAR him until he grew it back, and it has stayed exactly the same (aside from the fact that it’s now mostly grey) ever since. When guys my… Read more »
