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!!!

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 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. 😉

Janine (sugarkissed.net)

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

Bev Tyson

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


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!

Michelle @ Brown Eyed Baker

I am ALL OVER this! Awesome idea!

Meghan @ After the Ivy League

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 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.

luv what you do

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