The Best Rice Krispie Cereal Dessert

There once was a time that I created the Perfect Krispie Treat and put it on the internets and claimed it to be the best above all the rest. I did that.

But unfortunately I can never leave well enough alone. It’s like my raging FOMO, which my friend Kristan clinically classified me as a few years back, when things are good, couldn’t they be better? I mean what if someone else is having MORE fun that me?

Yeah I really need to work on that…

BUT I really think that my FOMO has lead me to today’s post. I thought I had the “Perfect”, but WHAT if there’s something better? WHAT IFFF?

Seriously it’s exhausting being in my brain.

A Homemade Marshmallow Fluff Krispie Treat Recipe

Anyhow, these Krispies I made today might be better than my Perfect for some people…but possibly not all.

Here’s the deal. I wanted to push Krispie Treats to MAXIMUM MARSHMALLOW capacity.

How many marshmallows can I stuff in a Krispie Treat and have them still hold their shape when cut. It’s really a tough job I have over here people.

When I was doing my Marshmallow Conversion experiment I got this idea…what about a Krispie Treat made from Fluff. Now I am sure this has been done, even though I didn’t consult Dr. Google…

But I didn’t want a Krispie with just fluff. I wanted the softness of the fluff, but still the have it hold together like a Krispie Treat should.

AND these krispie treats stay soft for days…it’s a miracle!

Y’all I nailed the socks off this mess. NAILED.

Tips and Tricks on Making Marshmallow Fluff Krispies:

The deal is, if you add too many marshmallows your krispies will get chewy and they won’t hold the shape. I tried that when I was developing the measurements for The Perfect. So I thought, let’s not add more minis, let’s add some Fluff, because it’s the same but TOTALLY different.

What ends up happening is you get the texture of a krispie treat with more airy volume, making it spongy and soft and gooey and DIVINE.

Fluff and mini marshmallows for krispie treats

Also, let me point out I mixed it up a little and added half Fruity Pebbles and half Krispie cereal.

I like the combo of the two better than making one with ALL Fruity Pebbles. I’ve done experiments on this as well. Trust me.

You could easily use any combo of cereals you like, or just use all one cereal.

First melt the marshmallows and stir in the cereal like you would a regular krispie…

Then get all busy with that Fluff. Or Marshmallow Creme…because as we learned yesterday they are really one in the same.

THEN mix in more minis. You know it.

Seriously look at that bowl of glorious white beauty…

And let it sit. You will need to let these rest for at least an hour, more if you can. The Fluff needs a little time to set up.

I’m telling you, while I still think my Perfect Krispie is a classic recipe that you should know, if you’re looking to take it a step further…elevate your Krispie game, if you will, this is the recipe for you.

  1. I just made these using only rice krispies and I added 1/2 tsp of vanilla. They are cooling in the pan so I haven’t tried them yet but they look so good.
    I did have a question about the marshmallow conversion chart. This doesn’t make sense to me. A 10 ounce bag of mini marshmallows should be 5, not 6, cups, as it also states 2 ounces is 1 cup .

  2. This is the best rice krispie recipe I have ever made! They come out perfect, fluffy and absolutely delicious!
    Thankyou for sharing this with the world! I’ve had this recipe bookmarked on my laptop for awhile now, and have made it with numerous varieties of cereals! They are all yummy!

  3. Hi! I was wondering if I could add pb to this recipe, if so how much would you think? Thank you so much!

  4. I have had this recipe saved for awhile and finally made it. I added 1 tsp of vanilla and only used Frosted Rice Krispies . This is hands down the best rice Krispie treats I have ever made. The marshmallow ratio to the cereal is spot on. I never thought to use fluff!!!! Seriously why not use it?!? I did not overly press these into the pan since I wanted airy treats and not little bricks Iike I used to make for my kids years ago. I did not find these overly sweet. Now I have to try this with cinnamon toast crunch cereal. Thanks for the great recipe. I will have to try more from your site!

  5. We (over here in Germany) had Kellogg’s Rice Crispy Squares like at least 10 years ago, they’ve been around for about 1 year in the German supermarkets and then they stopped selling those AND the cereal as well -_- They brought a special edition of cereal a few days ago so I finally were able to make some myself today aaand that recipe is FANTASTIC! Thank you SO MUCH for that I was craving those for 10 years XD The homemade are much better of course so thanks again and all the best from Berlin!

  6. Hi Shelly !! Could I add the circus frosted animal crackers to this recipe to combine your two recipes or would that not work ?

    1. You could add them yes! I would probably just add a cup of chopped cookies, and press more into the top, depending on the result you are going for 🙂
