Avalanche Bars

Avalanche Bars! Super easy, no bake treats that are the perfect combination of peanut butter, white chocolate, and marshmallows!
Avalanche Bars are one of my favorite and most popular treats here on my website. I made them back in 2010, not too long after I started this website, and they quickly became one of the most loved recipes on Cookies and Cups! I even made an Avalanche Cookie a few years back that was equally as loved. I have updated the pictures so they are a little more pretty, but equally as delicious!

Avalanche Bars are this deliciously addictive treat was introduced to me at a place called The Rocky Mountain Chocolate Factory.  Ever been there?  They have shelves and shelves of delicious looking candy apples and homemade fudge that I would always be THIS close to buying…but being a bit of a cheapskate I always went for one of the least expensive thing there…the Avalanche Bar.

At like, $3.50 it was still overpriced, but oh so worth it.  A strange but wonderful combination of white chocolate, peanut butter and marshmallow it is like rice krispie treat on steroids!

Avalanche Bars! Super easy, no bake treats that are the perfect combination of peanut butter, white chocolate, and marshmallows!

Clearly I knew I needed to learn to make these at home… and it turns out they are easy peasy!

AND I made a quick little video to show you JUST how easy…

I make these ALL the time, and I am sure you will too! They are an easy, classic treat!

  • Author: Cookies & Cups


  • 12 oz bag of White Chocolate Chips
  • 1/4 cup creamy peanut butter
  • 3 cups Rice Krispies
  • 1 1/2 cups mini marshmallows
  • 1/4 cup mini chocolate chips + 2 Tbsp for garnish.

  1. In microwave-safe bowl pour in white chips and heat on 50% power for 1 minute. Stir and continue in 30 second increments until chips are melted.
  2. Combine the peanut butter with the melted chips and add the krispies.
  3. Let cool approx 15 – 20 minutes stirring every 5 minutes or so to help cool.
  4. Add the marshmallows and the mini chocolate chips and stir to combine.
  5. Pour mixture into the prepared pan and spread evenly, pressing lightly with the back of your spoon, but do not compact too much, otherwise they will get hard.

    Hmmm, they sound pretty good. I do though think that I would prefer them with out chocolate.

    I'm in FL, also known as the Sunshine State, so I can relate to perpetual summer. 🙂

    1. Cecyle

      I’m going to make these with caramel chips. Chopped nuts would be good in these too. I’m going to use dark chocolate chips and pecans or walnuts for the type II diabetic in the family. These sound great.

  2. Goddess of Cooking

    They look really yummy! Shame on you for adding in the link for Rocky Mountain Chocolate tho. Now I have to go and buy some caramel apples and have them shipped to my house. We have nothing like that around here!

  3. Sara Tea

    Girl! These sound TOO good. I'll definitely try these out. I always raid those candy stores in the airports, but rarely got past trying anything other than the giant caramel apples! I hear you on the cold weather, I go to school in Columbia Missouri, smack dab in the middle of the country and walking across campus in 28 degree weather with 30 mph winds makes it EXTRA hard to go to class. Hang in there!

  4. Melanie

    I just moved from Houston, Texas to Portland, Oregon and while I like it in OR, I REALLY miss Texas. There's just something about that state 🙂

  5. Amanda

    OMG those look incredible! I just discovered, by accident actually, the wonderful flavor combo of white chocolate and peanut butter when I tweaked some oatmeal chocolate chip cookies. I am definitely trying these, they look awesome!

  6. Sue Sparks

    You're funny:) There is a Rocky Mt. Chocolate Factory in this area too, but I haven't gone there too often other than for buying a dog treat for my pup:) I like See's candy! Your bars look yummy!

  7. Mara...

    These look amazing!!! Rocky Mountain Chocolate Factory is one of my favorite places, ask my kids what my favorite store is…that's what they will say!! THANKS for sharing this recipe, i'm making it FOR SURE!!!

  8. betchacanteatjustone

    Very familiar with Rocky mountain chocolate factory and $8 caramel, chocolate, candy coated apples! I've not had an avalanche bar but I will definatley be making these!

  9. vickys

    Nothing better to cheeerrup a cold day than peanut butter and white chocolate. I have a love hate relationship the the weather. But least you have an excuse to buy cute coats and winter boots!

  10. Alexandra

    Oh baby, those look way too good. And I feel you on the whole summer/winter exchange… I'm from FL and I moved to Louisiana and whoa. 10 degree winter nights were NOT what I had in mind… I didn't even want to open the front door.

  11. Shauna from Piece of Cake

    Oh, man. I am always a sucker for Rice Krispie treats, but these are REALLY something. Wow! Love the lead photo too. 🙂

  12. Chey can cook! (and more)

    yum! love your posts as always:) i can't imagine going from TX to this! (i'm in MA, so i hear ya on the cold)

  13. The Cookie Mama

    Mmmmm…I am definitely trying some of these!!

    And hey…it is even cold in Mississippi…not as cold as in NJ I am sure, but you know 50 is freezing for us!!

  14. Jaime

    oh wow – i LOVE this stuff and have been wanting to find a recipe for them…. THANK YOU!! yes they are ridiculously over priced so i am glad i can make them at home now 🙂

  15. theregoesthecupcake

    I made these a few weeks back and they were wonderful. I had tried to recreate the Rocky Mountain ones last summer with no luck but this recipe hits the nail on the head. Thank you!!!


  16. Angela Payne

    Hello, a friend and I made these last night along with the Browned Butter Pumpkin Spice Krispie Treats and they were a HIT! I am not wanting to make the again and try many more of your great recipes! Great job!

  17. i made these last night for a newborn’s family and they were OBSESSED! grandma went on and on about them and made everyone who came to visit stop and try one. definitely a hit! thanks girl!

  18. Katie

    These look amazing and I’d like to make them for a cookie exchange. Do you use actual white chocolate (with cocoa butter in it) or just the white chips that are more common (and cheaper!)?

  19. Kelly V.

    I made these this afternoon and they have already been devored by my husband and 17 & 2 year old daughters! What a hit! Making more for oldest daughters arrival on Tuesday, after months of Army chow I am sure her sweet tooth will be happy! Thanks for sharing!

  20. You don’t know how much this recipe just made my day! I am new to the whole blogging thing, courtesy of Pinterest. Just hours ago, I drove past my local Rocky Mtn. Chocolate Factory and argued with myself about stopping for, you guessed it, an Avalanche Bar! I adore these! I kept thinking, “if only someone on Pinterest would post a copycat recipe for those…” Voila! I logged in to Pinterest and someone posted it, leading me to your blog.
    Thank you!

  21. Sweet Thing

    I loved these bars, never had them before and now I’m addicted. I must have not pressed them down enough in the pan as they sorta crumbled a bit. The chocolates chips on top also fell off. Next time I will drizzle melted chocolate over them instead. So delish.

  22. Sitkal

    Great… I had managed to forget all about these! Now I have to go make some. My tummy thanks you. My new jeans do not.

  23. Jaloo

    These look yummy. Be aware, however, that “puffed rice” is not the same as “rice krispies”. Puffed rice is chewier, not crunchy and the kernals are bigger, as in Quaker brand puffed rice.

  24. Ronna Melton

    Ummm … there’s a problem with the statement about the bars being over priced at $3.50, but oh so worth it ! See how that doesn’t compute ? I can’t leave ordinary Rice Krispie treats alone, much less these babies.

  25. Ashley

    I worked at Rocky Mountain for 2 years in Pennsylvania and when I saw Avalanche bark it was the FIRST thing I thought of….working at Rocky Mountain!

    1. shelly

      Thanks!! I wrote that post so long ago and am embarrassed about the pictures, but it’s one of my most popular 🙂

  26. I made these last night and they were easier to make than I presumed. This morning I easily cut and tasted. Before you keep reading, I must say, rarely is anything EVER to sweet for me. These bars are too sweet. One easy thing I thought for next time is add more rice krispies. This being said, I know they will still be a hit at my family BBQ today.

  27. Hi there! I could have sworn I’ve been to this website before but after browsing through some of the post I realized it’s new to me. Nonetheless, I’m definitely delighted I found it and I’ll be book-marking and checking back frequently!

  28. Lisa

    I’m moving from Texas to Wyoming next Feb. Yes, for love! It’ll be hard to leave Texas but, I’m happy to do it for my honey!
    Can’t wait to try this, they would be good with other flavor chips too! (Like peanut butter chips!)

  29. Just made these bars and they are as easy to make as they sound and they are just as good as they look. Will be adding these to my collection of pot-luck desserts, as well as our Christmas Goodies List. Thank you for sharing 🙂

  30. Brittany

    These are AWESOME! I just made them, RIGHT NOW, and they came out great. I can’t believe how easily they come together and how yummy they are! Thank you so much for this recipe, I will be making these again for sure!

  31. Lauren

    These were awesome and thanks to gluten free rice crispies everyone at My LifeGroup could enjoy them, so thanks! Gonna try the puppy chow crispies with the leftover rice crispies next time around.

  32. Jeanne

    I think I have made these seven times already. They are beyond delish! I messed up once and did not use enough chocolate…however the crumbly result was a great ice cream topper. I currently have a batch cooling with some crushed Oreos in the mix. I love how easy and kid friendly they are. My kins (4,3, and 1) can all help make these all the while holding my newborn. So much better than boring rice krispie treats! Anyway, thanks for such a great post!

  33. Cindy

    As a born and raised Jersey girl, I need to remind you that at least now you don’t have to pump your own gas! And I loved the RMCF, but I don”t know where one is (if they even exist anymore).

  34. Sarah

    lol I died laughing reading the beginning of this! I’m a Georgia girl and guess where my husband in from? Upstate New York. Do you have any idea what lake effect snow is? Neither did I! Turns out, i hate snow. Hate lake-effect snow even more! So now we are back in Georgia. 🙂
    And OMG do those avalanche bars look delicious! Rice Krispy treats are my absolute favorite treat of all time and to add white chocolate? mmmmmmmm

  35. MoonAngel

    I just made these and they are good, but super sweet, too sweet for me. That said, my boyfriend is going to love them. I didn’t use the marshmallows, since I didn’t have any, so there was no fluff to them, just chocolate, chocolate. 🙂

  36. I was looking for a good recipe and I found yours. The name first made me dream, then I made ??it following your advice. I cut my bar to break at 10am, this is a treat! Thank you.

  37. Thank you for your article (and please excuse me, English is not my mother tongue), do you write a second part to cover the subject entirety? In all cases, it’s a topical issue that will have to be treated in this way more often. Regards, Roger .

  38. Love these babies! Had to hide the remaining row. It makes more sense for my family of “Hoovers” to double this, which I did. Gave some away, too. I am going to do a post on my blog about these among other too-easy-to-consume treats. Thanks for the de-lish recipe!

  39. littlelauren

    these look SOOO good!!! I planned to make them for a church event tonight but forgot the white chocolate when I was shopping yesterday. my solution: substitute milk chocolate for the melted white chocolate, use the crunchy pb I already had in the fridge, and instead of stirring in mini chocolate chips, use part of a white chocolate bar (chopped). Tastes great but doesn’t look quite as fancy

  40. Saw this on Pinterest and it looks fabulous!! I see that it’s a few years old, so not sure if you are still in NJ, but I get it. I’m in San Diego, and I know that I can’t complain. But yep, I’m done with winter. It was 70 today, but only for a short time. short enough, but I put on my beloved flip flops which I haven’t worn for a few months. My poor, poor pale feet!! I’m definitely in need of stronger sun. Perhaps we should meet up in Hawaii for a plate of these gorgeous bars??? Aloha!!

  41. Jodi

    These completely fell apart when I cut them. Followed the recipe. Still taste good. I think next time I will stir the marshmallows in while still warm.

  42. go to rockymtnchoc.com and get on their email list and get notices when the 8 dollar apples go for 3 for 15 and other specials. anyone in jersey can go to atlantic city for apples.

  43. Jillian

    I just made these last night. The outcome tasted great, however, it was nothing like a bar. It was crumbly and had some chunks (similar to puppy chow). I served it to a bunch of hungry guys so needless to say they didn’t care what form it came in. Anyways as I was making these I wondered if I should melt marshmallow and mix the Rice Krispies in as if I were making regular rice Krispy treats? I didn’t see that in the directions but am wondering if it would help.

    Thank you!

    1. shelly

      You certainly could try that! I can’t imagine it would taste anything but great 🙂 I haven’t ever had the problem that you had with the crumbling, but I’d love to know how they come out doing it that way!

  44. Jen

    I second MoonAngel they are too sweet( feedback from the bake sale) If I make them again I’ll omit the white chocolate and make them with the traditonal way with peanut butter and chocolate chips.

  45. I stumbled across this recipe through Pinterest and decided to make them as a treat for a Board game date at my house with friends. They were sooooo easy to make and they are beyond delicious. I don’t think I could ever go back to regular rice krispies treats again. Perfect snack to make at home or take over to a friends house. I loved the white chocolate in this recipe, (I used squares instead of chips,) it balanced out the peanut butter and other flavors nicely! Thank you for sharing.

  46. Cyndy

    Saw your bars on Pinterest and knew I had to make them. so easy and so delicious. I have an allergy to peanuts so I subbed almond butter. Thanks for a wonderful Treat! My coworkers are asking for more. Thanks again


    1. Casey

      The first time I made these they were very crumbly. Second time not as much. The first time I followed the recipe exactly. I used Ghirardelli white chocolate chips. The second time I just used generic white chips and added a little extra Rice Krispies. Any thoughts or similar experiences. I think I liked the taste of the generic chips better than the real chocolate. Weird, huh?

  47. Pstricia

    Happy Holidays! Have you ever made these using a larger amount of peanut butter 1/3 or 1/2 cup? Do you think it may negatively affect the consistency? Make them too soft to work with etc.? Or does the recipe as written provide the yummy peanut butter flavor I crave and want? Also have you ever tried adding some melted marshmallows to the mix?

    Thank You!

    1. Shelly

      If you add more peanut butter it will definitely affect the texture… but you could use peanut butter chips in place of the chocolate chips to amp up the peanut butter!

  48. Danielle

    Would I be able to cut these into star shapes using a cookie cutter? Do they hold together well enough? They look delicious!

    1. Shelly

      They will hold their shape, bu they can get slightly crumbly if not packed well enough. If you do use star shapes though, you will have a lot of unusable bar leftover, as you can’t really shape this after it’s dried. Hope this helps!

  49. Becca

    Question: Do you think these would be good with a mixture of cereals/crackers instead of just rice crispies? like a combination of broken up graham crackers, chex and rice crispies, for a total of 3 cups? Thanks!
