Peanut Butter Cup Fluffernutter Blondies

Last week I went to Ohio.

I had to fly there.

I’ll tell you all about Ohio later, but today let’s talk about airports/planes.

Going on a trip is all sorts of exciting, but the getting-there part, not so much.

Airports are scary and confusing places filled with weird, impatient people.


I mean, when did I become the last normal human?

First, I got into the wrong line to check-in…and the man behind me was obviously an expert traveler because he kept sighing at me really loudly when I kept forgetting to move 1 foot up in the maze line.  Finally I made it to the front of the line only to be told by the super helpful woman behind the counter that I needed to go check-in at the other desk, by way of another, super-long maze line.

All this waiting to check my bag.  Yes, I’m a bag checker, no matter how light my load.  I get anxiety when I carry my bag on.  What if there is no space in the overhead compartments when I get on the plane?  I have been faced with that dilemma more than once.  I end up standing in the aisle looking around for space, which never happens to be above my own seat.  I start sweating and searching with panicked eyes for any sliver of space that I can squeeze my over-packed carry-on into, knowing that the long line of people behind me are getting annoyed by me standing there like an idiot.  Also, I am 5’2″ which makes hiking my bag over my head hard enough.   I have been hit in the forehead with my carry-on more than once.  It is embarrassing and painful.  So, I am a bag-checker.

After I got my bag checked, I had to take the air train to the other terminal.  In my airport the train has little separate cars, which are great when you have your family with you, but if you are alone you’re forced to sit in a tiny space facing some random stranger who will inevitably stare at you until you make eye contact.  The thing is, once you’ve made eye contact it’s like you have acknowledged their existence and now have to say something.

I always get alarmingly nervous in these situations and say the wrong thing…like if the stranger says, “Pretty cold out today”, I usually come back with, “Nice to meet you.”  Then I sit there for the next 3 minutes feeling like a moron staring down at my feet.  I really shouldn’t be allowed in public.

On my day of travel I was running slightly behind and by the time I got to the gate I was starving.  The only thing near my gate was a stand that sold nuts.  I am allergic to almonds, so obviously I steer clear of those, but in general I avoid most nuts.  But since I was so hungry I decided to throw caution to the wind and get a bag of cashews.  I ate a few handfuls and boarded the plane.  As the doors closed I started having trouble breathing.  I was convinced I was going into to anaphylactic shock because of the cashews.

Here’s my thought process:  Ok, breathe, calm down.  What if I am dying?  What if I die here?  Should I say something?  Should I draw attention?  People will be mad if I stop the plane.  People might not notice if I die.  I have a window seat.  They’ll think I am sleeping.  What do I do?

Well, I settled on dying in my seat rather than embarrassing myself.  As I sat there trying to breathe I realized that I was a complete idiot and should not be allowed out of the house by myself.  Luckily, I gained my composure and realized that I was just panicking and I wasn’t dying of an allergic reaction to cashews.

I am no good in pressure situations.

Don’t even get me started on connecting flights!


Like I said, I’ll talk about my trip another day, but among other things that I left Ohio with, was the idea for these blondie bars.

My kids love Fluffernutter sandwiches.  (For those unfamiliar, Fluffernutter is peanut butter and Marshmallow Fluff.)

I decided to amp up the idea and add some Reese’s Peanut Butter Cups to the mix as well…can’t be bad!

I ended up with a buttery, peanut butter bar with Fluff swirled throughout and yummy chunks of Reese’s to add a little extra pizzazz.


Peanut Butter Cup Fluffernutter Blondies

First you make you batter…really easy.

Don’t forget to fold in your peanut butter cups.  A whole entire 10.5 oz bag of full sized cups…minus one for tasting.  You need to make sure they’re not poison.

Spread your batter into a greased pan.

Now, get your Fluff ready.

Drop that randomly on top of your batter…

and swirl it around…

Bake it and eat.

Nothing wrong with that!

Now, sweets aside, you really need to hop over and check out my other site…we play pranks on our kids and video it, which isn’t mean at all, we make crafts because we’re kinda crafty, we snoop in people purses, we have fun meal plans and man-judging just to name a few.  Seriously, it’s kinda the perfect place!

And one more thing…don’t forget to enter in my babycakes giveaway…it’s open until Sunday, November 20th!

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?

    I don’t know how I came across your blog but I love it!!!! Your posts always crack me up but today’s had me crying from laughing so hard! As an Ohioan I’m glad that we inspired you to make something so amazing, I’m going tonight to get the iingrediants!

  2. I love how everyone has a different perspective of flying. It cracks me up. I try NEVER to check a bag. I have had too many bags miss connecting flights so I try to pack lightly. I typ. wear a crap ton of layers… shirt, sweater, coat… that I can take off so that my bulky sweater does not have to be packed, letting me use a smaller suitecage. Also goes for shoes, wear the biggest bulkiest shoes on the flight so my flip flops are in the suitecase.

    Oh my goodness. I am SO glad I stumbled upon your blog. I think I did because of Callye and Ashleigh’s pinterest cookie series. But no matter. Whatever brought me here I am so happy. I check your blog every day and am so glad when you post. YOU MAKE ME LAUGH SO HARD. I think we are sisters seperated at birth.

  4. Shelly, you are too funny. I also hate the moment when I have to put my way-too-heavy carry on in the overhead compartment. I’m also short and no one ever offers to help so I always end up hurting myself.

    If these were the result of your trip then it was worth all the awkward moments:-)

  5. I love your flavor combo’s…you never cease to amaze me when you come up with yet another winner of flavors. As for travel, i don’t do it, or rather I have not traveled in soooooooo long…but airports were strange the last time I went, so I can only imagine that they have progressively gotten weirder as time has evolved.

  6. Umm yeah. All of the above. I’ve had to fly twice in the past three weeks and many panic attacks have abounded. Many.

    having these bars on hand would have totally calmed me down.

  7. That is the saddest story ever! I grew up traveling ALL the time, and am no longer bothered by all the weirdos and crazies at the airport; I’m one of them – they are my people 🙂 If you need a travel guide to help you navigate the airport lines and figure out if you’re dying or not, please don’t hesitate to ask! I’ll help ya! Oh, and I’ll make these bars just for our flight!

  8. You and these amazing treats with peanut butter! I’m dying to make your banana bread and now THIS?! PB and marshmallow fluff?! Thank you! And I’m here in Ohio, so I hope your trip was without any scary incidents! Besides the airport/plane situation. Weirdo. 😉

    I’m not sure how I found your blog, but I’m glad I did. I like you, you are awesome…this story made me laugh and realize we may have a lot in common. I am a complete spaz in pressure situations and labor under the delusion that I am dying/unable to breath/or going into anaphylactic shock at least once or twice a week…
    Oh, and your photos are really good and your recipes look fantastic, I will have to try to make these blondies soon.

  10. I just flew from Boston to Anchorage this weekend and I wrote about my thoughts on airplanes also! Check it out, as I think we both dislike airports. Also, these blondies look sinfully delicious!


  12. Oh, Shelly, the airport travel…yes, indeed. It’s like this massive cattle call, everyone is in a hurry to go no where and they are more concerned that you have 3.000001 ounces of body spray in your purse than is really necessary. Or how about being a nursing mother or mother to a baby and trying to get milk on board…seriously it’s nuts. And no one is polite. Everyone just sighs, rolls their eyes, or yells. Travel is sooo glamorous, right? Sorry you had to deal with it. I am all too familiar with your scenario.

    On lighter matters, these blondies look awesome! I have made something sort of like these that I adapted from a picky-palate/jenny recipe. Cake mix, PB, fluff, and lots of white choc and sweetened condensed milk, too 🙂
