Why Make Avalanche Bars

As many of you already know, rice krispie treats are one of my all time favorite desserts. I’ve even come up with a whole set of tips for how to make rice krispie treats at home.

Childish? Maybe. Delicious? Yes.

Also called avalanche bark, these upgraded Rice Krispie Treats are packed with peanut butter, chocolate chips and plenty of miniature marshmallows.

Rocky Mountain Chocolate Factory is known for their giant avalanche bars (and their Tiger Butter)!

I’m so delighted by these bars, folks.

  • Two different kinds of chocolate
  • Creamy peanut butter
  • Most importantly, rice krispies!

Making rice krispie treats reminds me of the days back in high school when my friend Steph and I would make a whole pan of them and eat it in one sitting.

This is totally possible with today’s dessert!

Ingredient Notes

Here’s everything you need to make Rocky Mountain Chocolate Factory Avalanche Bark Bars: (scroll all the way down for measurements and directions)

Ingredients needed to make rocky mountain avalanche bark.
  • White chocolate chips– Use a good quality, we love Ghirardelli brand.
  • Peanut butter – I used creamy but chunky would be good too if you like pieces of peanuts in your bars.
  • Semi-sweet chocolate chips – Miniature morsels work best. If you only have full sized, those will work just fine too.
  • Mini-marshmallows– make sure they are fresh and not stale. Stale marshmallows don’t melt as well, and the final result will be stale tasting too!
  • Rice Krispies Cereal – fresh, not stale!

It takes hardly any time or effort at all to make copycat homemade Avalanche Bars. I found the hardest part was WAITING while they finished setting up in the fridge.

Tips and Tricks

  • Be gentle: Make sure to press the mixture into the pan GENTLY! The firmer you press, the firmer the finished treats will be and they may be difficult to get out of the pan.
  • Melting white chocolate: You can use the microwave to melt the white chocolate chips and peanut butter. Place them in a microwave safe glass bowl and zap for 30 – 45 seconds at a time, stirring between rounds until everything comes together.
  • Be even: When folding the chocolate chips and marshmallows in, check to make sure they’re evenly distributed throughout the whole rice krispie mixture. That way you get all the flavors and textures of the avalanche bark in every bite!

  1. I like that your recipe makes a bigger batch (double the cereal to other ingredients ) equaling more product for less cost… thanks

  2. I tried to make these several times and kept messing up – I think I saw something you might want to correct when I made them this morning. In your step by step directions it says to cool after adding the marshmallows and chocolate chips but in your recipe it says to cool before adding the marshmallows and chocolate chips. I did it like the recipe card this morning and I think they are finally right! (My husband didn’t mind all the failures though.)

  3. These really belong in a 9×13 pan. Or two 9×9s. I used the same crate and barrel dish as you have in your photos and it was almost overflowing. All other recipes for these bars call for about half of the ingredients and a 9×9 pan. I’m sure they’ll be tasty when we try them tomorrow. They’re just way too thick.

  4. Hiii! I tried to make these tonight & sadly they fell apart. I followed the instructions, maybe I added too much Rice Krispie cereal? I added more peanut butter in hopes it’ll keep it in tact but they still fall apart. Any suggestions? They taste good! But won’t stay intact 🥺😭

    1. I’m not sure what happened. I suggest making sure you measure the ingredients accurately for best results 🙂 ENJOY!

  5. YUM and so easy to make. I made two pans from this recipe and my hubs and kids have not stopped eating them. So good!

  6. 5 stars
    We loved this variation of the rice krispie bars! So delicious and so easy to make, my daughter made them!

  7. You weren’t kidding when you said these are better than rice crispy treats. I like them about a hundred times more! They are dangerous!

  8. Hello,
    I just love your blog!! I was wondering where the recipe is for the Rocky Mountain Chocolate Factory’s Avalanche Bark is.
    Thank you.
    Hugs, Teresa

  9. Umm, so I super miss the days of eating an entire pan of Rice Krispies in one sitting, lol. Now, I’d have to start walking to work to balance that out and I live 20 miles from where I work. I’d still go for a “one sitting” eating on occasion though! I used to live by a Rocky Mountain Chocolate Factory and I forgot how much I loved these — can’t wait to try them!

  10. Chocolate, peanut butter and marshmallows? Yum!

    Thanks for linking up with Sweet Tooth Friday. Don’t forget to link back!

  11. You know I’m overweight. Why do you keep doing this?
    It’s like watching the food channel at 10:30 PM and I have to go out and make a hamburger.
    Dad
