Cake Batter Blondies with Marshmallow Buttercream

Cake Batter Blondies might be the best invention ever. These are topped with delicious Marshmallow Buttercream to make everything in the world right.

Are you guys on Pinterest?

It’s such a fun site where you can consolidate fun things you see on the internet.  You “Pin” the pictures to boards you make and you can share them with people.  And you can follow others and see what they pin and vice versa.

Anyway, while it is fun and great and you can find all sorts of cool things it makes me a little crazy because there are so many talented people out there coming up with tons of things I wish I thought of!

BUT I learned at an early age not to be envious of what others have.

It was a hard lesson.

It involved sausage.

Would you like to hear?

Thought so.

Ok, the year was 1985.  I was in the 5th grade.

I had a friend named Michelle.  She was really a nice girl.

Well, we sat next to each other everyday at lunch.  We both brought our lunches pretty much every day.

Her lunches were always awesome…everything was in its own reusable container…no plastic baggies for her.  AND her mom always put in a napkin and a plastic utensil.

I asked my mom one day why she didn’t give me a napkin in my lunch box…

I will never forget her response…”That’s why we pay taxes, so you can use napkins at school”.  Hmmm, really mom?

Moving on…one day Michelle pulled out her lunch and her mom had packed her a small little can.  The label on the can read “Vienna Sausages”.

I sat and stared.  It was such a cute little can with its own pop top.  And it was from Vienna…where ever that was.

I looked down at my lunch…a tuna sandwich, Capri Sun, and  applesauce.  SO American.  Not Viennese at all!

I watched her open the can and eat the little sausages one at a time…laughing and joking.  Which translated to my 10 year old mind, “These sausages are so delicious and gourmet and INTERNATIONAL”.  She may as well have been wearing a scarf and a beret smoking a long thin cigarette.

Of course I went home and told my mom that I MUST have Vienna Sausages in my lunch.

Mom:  “Ack! No way!”

Me: “But MOM!  Why don’t you want me to learn about other cultures?  Sure, you take me to the Chinese Buffet…but what about EUROPE?  I want to learn about Viennese people!”

Mom: “No way, they’re gross, like dog food.” (the sausages, not the people)

Me: “MOMMMMMMM!  PLEASE!  I need these Vienna sausages to learn about the world!  You won’t buy me Bongo jeans and you say jelly shoes are bad for my PLEASE let me have the sausages!”

Well, she gave in.  I suppose she decided that the Vienna sausages were less of an investment than the Bongo Jeans.

So I went to school proudly with my can of Vienna sausages for lunch.  She even packed me a plastic fork and napkin.  Embarrassingly enough I decided that on this day I would wear my black and white striped shirt, I assume to look like a gondolier…I apparently thought Vienna was in Italy.

Finally when lunch time rolled around I proudly removed my can of sausages from my box.  I popped the top and stared down at the flesh colored sausages floating in water and promptly dug in.

I speared the first sausage with my plastic fork and took a bite.  I guess I was anticipating something more along the lines of a hot dog but what I got was a mouthful of meaty, mealy grossness.  NOT European.

I gagged as inconspicuously as possible and watched my friend as she ate her sausages one at a time, seemingly savoring each bite.

In hindsight I know why my mom packed me a napkin on that day…it was an escape plan.  I aborted Operation Eat European into the neatly folded napkin and placed it back in my lunchbox.

When I arrived home my mother asked me how the sausages were?  To which I replied, oh they were delicious.

I could never let her win.

It was in that moment I realized that while Vienna Sausages sound exotic and fancy they aren’t for me.  I am neither exotic or fancy and should stick with tuna on whole wheat.

The end.

So while I browse Pinterest and see all the creativity of others I try not to be envious of what they have created.  You wanna know why?  Because as nice as they are they’re probably at home eating Vienna Sausages.

That, my friends, is a life lesson.


Now, with every rule there is an exception…because I found these delicious looking bars on pinterest and pushed my Vienna sausage fear aside.

I decided I must make them.  Immediately.

These are easy and it all starts with a cake mix!


Cake Batter Blondies with Marshmallow Buttercream.

You need an egg, a cake mix, 1/4 cup of oil and 1/2 cup milk.  I added in some white chocolate and marshmallows for good measure 🙂

Then I baked up…simple!

And then I frosted them!

Hi! I’m Shelly and I’m an addict. Of the buttercream sort. I started this site a few years ago as a way to justify my sugary, buttery obsession with desserts. It has worked out well for me so far, because as it turns out you guys all love sugary, buttery desserts too! It feels good to know you're not alone, doesn’t it?

When you say 1 cup marshmallow fluff, do you mean a measuring cup or an 8oz. Container???


Awesome buttercream recipe! Thanks!


is a 9×13 pan ok to use?


How much frosting does this recipe yield?


These are freaking awesomeness! I’ve made this several times and have done it with diff cake mixes too and added other stuff. Thanks for the great recipe. I love your blog it’s my fav! I’ve made a ton of stuff from it.


Great recipe’s, going to make Smores Whoopie Pies……


Just a quick question – I have been looking for a buttercream recipe that will hold up outdoors for a few hours without refridgeration – I am not too excited about the ones that are shortening based but this one sounds yummy – do you think it will be ok unchilled since there isn’t too much butter?

Yes those sausages are pretty bad but we keep them in our emergency cupboard, having lived in a hurricane prone environment. Can’t wait to try the icing.


Hey babe! Glad you like the Cake Batter Blondies 🙂 I hate to be a pain, but would you mind linking my post as well? I’m almost positive the originate back to my post 🙂 Thanks so much, I really do appreciate it!


I just cried a little. ='( I found your s’mores whoopie pies from Pinterest and thought they would be PERFECT for my daughter’s indoor campout birthday party. So then I mosey on over to this page to find out how to make the marshmallow buttercream and find out it requires Fluff! They don’t sell Fluff down here in San Antonio – just marshmallow cream (not the same consistency)! PLEASE tell me marshmallow cream is an acceptable substitute!


Ha! You had me at hello! Loved the story and can’t wait to try the recipe. 🙂

Shelly! You are da bomb! I’m a Texas (San Antonio, though) gal too and I just found your recipe for pumpkin dump cake on Pinterest and thought yum and that I could actually make that without struggle. Then I stumbled upon your Candy Corn Bugle Blog and I about died laughing, I had to call my sister and read it to her…me being the person that gets dragged to exercises that kill me, her being the one doing the dragging! I know we just met but I can tell you are going to be one of my new besties in… Read more »

LOL that was an awesome story. I love Pinterest too and am very glad to be following you now!


I have a sausage story too… but that involved my boyfriend (now husband) offering to pay me $1000 to eat a jar of baby food sausages. I quickly realized that I would never win Fear Factor or Survivor, nor would I ever have $1000. The blondies look delish! How do you stay thin with all of the goodies in your house? Or do your neighbors just love you?


I LOVE Pinterest! However, I do not eat those nasty little things haha Totally snagging this recipe and making these blondies this weekend. Yum!


I really want to try to send these to a friend who is going though a rough time…how do you think they would hold up in the mail??? The frosting makes me nervous….. Worse comes to worse I’ll just have to eat them myself! Thanks!


Love the bright colors! What a fun treat!


What a GREAT story…and you’re right – it was a life lesson! The blondies look deliciously easy! I’m glad you tried them!


Hi I love your site web, tanks for make things delicius.
