Krispie Treat Fudge combines the best of gooey marshmallow treats and fudge! The perfect bite-sized dessert for sharing — only they taste so good you’ll want to keep them all for yourself!

Krispie Treat Fudge recipe: gooey krispie treat flavor with a decadent fudge texture. A must make!

Why this Recipe is Best

  • Crispy rice cereal inside smooth fudge.
  • Delicious gooey marshmallow flavor.
  • Topped with chocolate chips.
  • The perfect size to pop into your mouth!

Today I pulled a fast one on my family. You see, they have a strict rule with me that I am no longer allowed to make Rice Krispie Treats.

It’s not because I make them poorly (because my recipe is amazing).

It’s because I don’t share.

They are my Achilles heel, so to speak. I will fight even the smallest child for the last, Perfect Rice Krispie Treat at a potluck. (don’t think I’m kidding).

I have been caught eating an entire pan, by myself, before my children even arrive home from school. Guilty.

Hey, it’s not my fault that I perfected how to make rice krispie treats!

So, in an effort to get around their “rules”, I created this delicious Krispie Treat Fudge.

One of my favorite versions of a krispie treat is this Avalanche recipe. It comes from Rocky Mountain Chocolate Factory. It’s rich, and chewy, and mouthwatering.

I kept the peanut butter out of today’s fudge recipe because I wanted the fudge to taste more like a classic krispie treat. However, adding peanut butter is on my ‘to do’ list for next time. And yes, there WILL be a next time!

Ingredient Notes

The base for this fudge is a familiar combination of heavy cream, butter and sugar.

You’ll also need these ingredients to turn it into Krispie Treat Fudge!

  • White chocolate – I use baking morsels. They melt quickly and easily into the other ingredients.
  • Marshmallow cream – It’s also called “fluff” and is combined with the white chocolate to give the fudge its soft, smooth consistency.
  • Rice Krispies – Or use any brand of puffed rice cereal!
  • Mini marshmallows – For that rice krispie treat flavor.
  • Mini chocolate chips – Gives the fudge a tasty and eye-catching finishing touch.

Tips and Tricks

  • Use an electric mixer. It’s the quickest and easiest way to combine the hot butter mixture with the white chocolate and marshmallow cream.
  • Chill the fudge mixture for 3 hours before serving. It tastes delicious cold, straight ouf of the refrigerator.
  • This fudge doesn’t keep as long as other homemade fudge, so try to eat it within 5 days. After that, the rice cereal loses its crispiness.

Recipe FAQs

Can I freeze this fudge?

I don’t recommend it. Unlike other fudge, this rice krispie treat fudge one doesn’t hold up well to freezing. The cereal will get chewy and mushy in the freezer.

Can I use regular marshmallows instead of mini?

You can use regular marshmallows. Just cut them into smaller pieces before adding them to the fudge.

What other substitutions can I make?

For a peanut butter addition, swap out the mini chocolate chips for peanut butter mini morsels!

You won’t be able to each just one piece of this Krispie Treat Fudge. It’s just too good to resist!

  1. I’ve made this for my daughters class and it was a HUGE hit! I’m going to make them again this year but I’d like to bring down the sugar content. Do you think I could simply reduce the amount of sugar and count on the marshmallows and white chocolate to bind it all or will it lose some of it’s fudgy-ness? Any suggestions would be greatly appreciated!

  2. I’m glad I’m not the only one who fights small children for dessert. Hey, all’s fair in love, war and dessert. Take no prisoners!
    I love that you used fudge as a loophole for not baking krispie treats. You are hilarious, Aimee!

  3. You are a genius! This sounds amazing!! Love that you fight kids over the last rice krispie. Hehe!!!

  4. Oh WOW!! You are officially a genius! What a perfect marriage between fudge and rice krispie treats!

  5. Love the way you got around the “rules”- and I think your kids are certainly glad you didn’t listen to them! Can’t wait for the peanut butter version 🙂

  6. Hehehe you made me laugh Aimee! Oh I am so guilty of the same thing! I believe in moderation but gosh its hard, says the girl who had 3 spoonsful of Nutella last night. This krispie treat fudge looks irresistible!!! 

  7. I can’t remember the last time I had a rice krispie treat!! I’m so excited about these!!

  8. This is so so so so SO brilliant, Aimee! I cannot believe you combined two of my favorite things. Pinned! 

  9. I want ALL the fudge! (And rice krispy treats for that matter) How about you invite me over, we “taste test” the entire batch and keep it our little secret? Mmmkay? 😉

  10. Rice Krispie Treats are my achilles heel too and I don’t share either! 

    And this is fudge, white chocolate, an avalanche bar, RKTreats (and heavy cream) all rolled into one…OMG! YES I want this!!

  11. Hahahaha!  I love that you have been banned from making krispie treats because you can’t stay out of them!  LOL!  And I also love that you got around that by making fudge with your beloved treats!  You are my sweets hero!  These seriously look amazing!
