Fluffernutter Sandwich Krispies


These Fluffernutter Krispie Treats are fantastic! And super easy!

There are a few things that I have learned as I have gotten older…
I’ve learned that flat front pants are better than pleated.
I’ve learned that classy isn’t in how much money you have, but how you treat people.
I’ve learned that when in doubt, choose red nail polish.
I’ve learned that you shouldn’t use a Groupon for Botox.
And I’ve also learned that a no-bake dessert is equally as delicious as it’s baked cousin.

I’m not saying this because I bathe in marshmallow and butter. I’m saying this because it’s a true fact.
You don’t have to agree with me here, but you certainly can’t disagree with me.

So let’s talk today.
About krispie treats.
My love.
My boo.

And today we will talk about stuffing krispie treats.
Because it’s easy. And because it just feels right.

So here we are…Fluffernutter Sandwich Krispies.
Not technically a “krispie” because I used “Honey Bunches of Oats”…don’t argue.
PhotobucketAll you do is take your cereal…
PhotobucketMix it up with some marshmallow and butter…
PhotobucketNow here’s the trick…spread it out thin in a jelly roll pan (15×10 in)…
PhotobucketLet the stuff cool for a beat and then slice it in half.
PhotobucketSpread one side with Marshmallow Fluff and the other with peanut butter…
PhotobucketThen carefully lift up one side and place on top of the other.
PhotobucketSimple dimple.
There you have it…stuffed krispie treats.

Have a spectacularly great July 4th!!!

Brilliant! I love the method of spreading the pb and fluff and then “sandwiching” the two sides together. Such a fun treat for kids and adults alike!

Oh my oh my!! Any dessert that includes cereal is amazing…you took krispie treats to another level! Love this, Shelly!

Freaking brilliant idea to use Honey Bunches of Oats…one of my favorites. Love, love this! And bathing in marshmallows doesn’t sound like a half bad idea!

sue @ cakeballs, cookies and more

well it sure looks good, no arguments there.

Cereal and peanut butter? This belongs on a health food blog, I’m pretty sure. I love this idea!

July 3, 2012 12:33 pm

I want to live the rest of my life alternating between spoonfuls of peanut butter & marshmallow fluff. Amen.

I have never made rice krispie treats. I’m 30. It’s probably all in my head, but I’m intimidated by them for some reason. True story.

This is my 3 year old son’s favorite cereal! He’s kind of a little weirdo child you see, I will eat the Cocoa Pebbles and Lucky Charms but he will eat Honey Bunches of Oats and Fiber One Bars… I guess he’s kind of an old man at heart when it comes to breakfast choices.

But we both share a special love for peanut butter and marshmallows and if I make this beautiful concoction I’m prettyyyy sure I will be his hero =) Thank you!!

Perfect way to use up some cereal & the Botox/Groupon intro made me laugh. I need to hear more on that one!

July 3, 2012 1:05 pm

You, Shelly, are a delight.

I don’t know you…but I know it’s true.

How can you NOT be?

Stuffed krispie treats are the bomb…especially stuffed with peanut butter and fluff! Anything with that combo is a winner for sure:-)

July 3, 2012 1:44 pm

Marshmallows and peanut butter are amazing together!

July 3, 2012 2:06 pm

You need a blog solely devoted to krispie treats, girl. These look delish!

Oh… and they have groupons for botox???

July 3, 2012 2:11 pm

You said groupon and botox – hahahaha…. : ) These look ahhhhmazing!

My mouth is watering! I am going to buy fluff after the gym tonight…. That’s right- I will be making these and devouring them right after the gym 🙂

Fluffernutter meets Rice Krispie treats. I like this… I like this a lot! 😀

July 3, 2012 4:07 pm

Oh my goodness, you are a genius! My apartment is unbearably hot, so I refuse to turn on my oven and have been suffering without my baked sweets. I think this will definitely satisfy me for the week!

Oh boy…these look dangerous.

Erin @ Dinners, Dishes, and Desserts

No bake desserts are equally as delicious, that is for sure! I love this idea of a sandwich krispie treat, so creative and yummy!

Ooo, now I’m super excited. A friend of mine recently discovered that they finally stock and sell marshmallow fluff at one chain shop here in the UK. I’m definitely going to have to go to my local one to see if they stock it too so I can make these. They look awesomesauce!

Now THAT is a sandwich I’d like to eat. 🙂

Um, you’re a genius. A rice krispie treat genius.

Can I ask where you got the font in your first picture for “sandwich?” I have a small addiction to fonts, you know.

I love your grown-up talk! Very classy and mature! I love the cereal you used in this, it’s my favorite 🙂 this is a great dessert to have any time of day..in fact, I might just make it breakfast!

luv what you do
July 3, 2012 11:04 pm

Where do you ever come up with these mouth watering recipes? I wish I were more creative in the kitchen!!!

July 3, 2012 11:04 pm

I love anything that involves peanut butter. Even no-bake things. But probably not botox. Not that that involves peanut butter, but even if it did…I probably wouldn’t love it.

Okay, I know people say this all the time. But I am literally making these AS SOON AS POSSIBLE. Holy crap. Can’t even stand it.

I am ALL OVER this! Awesome idea!

July 4, 2012 8:31 pm

Ok, so I just made these. I didn’t have the cereal you used so I subbed in Peanut Butter Cheerios. OMG. Totally made my day. So worth every calorie!!! Thanks!

I made these wrong (apparently I’m not great with directions) and used Maple Nut Oatmeal Crisp and they are still FREAKEN’ great!

These look yummy! Is there a reason you prefer Honey Bunches of Oats to Rice Krispies?

I bow to you Queen of all Krispies!!! Guess what I am making this weekend?!? KRISPIES!!! I’m so excited. I hope they are worthy of your creations! These are going on my must-make list FOR SURE! Fluffernutter?!? *sigh*

PS…I must know. Have you *tried* a Groupon for Botox? I must say, I was sorely tempted by a photofacial groupon last week. 😉

I have on my “to do”list for tomorrow to make similar treats, but with hot fudge and peanut butter (TRY them!!!). May have to make a batch of these, too.
