Chewy and delicious, these peanut butter white chocolate Avalanche Krispie Bars are a copycat of the famous bars from Rocky Mountain Chocolate Factory. They’re even better than the original!

I’m so delighted by these bars, folks. There are two different kinds of chocolate involved in Avalanche Bark, lots of creamy peanut butter and most importantly, rice krispies.

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.

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!

What are Avalanche Bars?

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.

The first time I tried Rocky Mountain Chocolate Factory’s Avalanche Bark, I fell in love.

I knew I’d like it because, hello, RICE KRISPIE TREAT, but I was blown away by the rich flavor and soft chewy texture.

I tried to replicate their recipe immediately, and I am proud to say this is pretty darn close to the real thing. I’m sure their white chocolate is a little bit of a higher pay grade than mine, but hey, you gotta use what you have!

How do you make Avalanche Bark?

Unlike most Crispy treats recipes, these bars are held together not by melted marshmallows and margarine, but by an ooey gooey mixture of melted white chocolate and peanut butter.

Then, you fold marshmallows in along with chocolate chips before letting the bars set. Bliss! I’m so glad Rocky Mountain Chocolate Factory introduced me to Avalanche Bars and even more glad that I figured out how to make them at home.

What you’ll Need

Here’s everything you need to make Rocky Mountain Chocolate Factory Avalanche Bark Bars:

  • White chocolate chips
  • 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, cut them into smaller pieces before adding them to the recipe.
  • Mini-marshmallows

So simple. So good.

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.

It’s well worth the wait. Just a half hour later, sweet and peanut buttery Avalanche bars are yours to devour!

How to Make Avalanche Bars

STEP 1. Melt the white chocolate chips and peanut butter together until creamy.

STEP 2. Fold in the rice krispies.

STEP 3. Add the marshmallows and semi-sweet morsels and stir until combined. Let the mixture cool for about 10 minutes, then lightly press it into a buttered 8 x 8 baking dish.

STEP 4. Refrigerate for 30 minutes, slice into squares and serve cold!

Anything bars you don’t eat right away keep best covered in the fridge. Be prepared for everyone to gobble these up!

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!
Avalanche Krispie Treats are made with peanut butter and white chocolate. Melt in your mouth, chewy and delicious!

  1. 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

  2. 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!

  3. Chocolate, peanut butter and marshmallows? Yum!

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

  4. 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.
