These Fruity Pebble Rice Krispie Treats are super colorful, fun, soft and oh so delicious! The colored Rice Krispies add a vibrant twist to this classic sweet treat. 

If you’ve been following Salt & Baker, then you know my history with Rice Krispies Treats! They were also so hard and dry and I never liked them. Fast forward and I figured out all the right tricks to getting the perfectly soft and gooey version of these cereal treats. Try my classic recipe (linked above) and my Salted Brown Butter Rice Krispie Treats, M&M Rice Krispie Treats and my Scotcharoos for some delicious Rice Krispie goodness!

Why This Recipe Works

  • Salt balances the flavor. Adding Kosher salt to the mallow mixture helps accentuate the flavor and balance out the major sweetness of the Fruity Pebbles cereal.
  • Extra gooey! By only melting a portion of the mallows and adding 2 cups of mallows at the end, those last mallows don’t fully melt which keeps everything extra gooey and soft!
  • Fun and vibrant. Using Fruity Pebbles cereal helps make these colored Rice Krispies so much fun for birthday parties and kid playdates! 

Ingredient Notes

  • Unsalted Butter: If using salted butter, cut down on the salt by 1/3. 
  • Mini Marshmallows: The mini marshmallows melt more quickly so there’s less risk of over cooking them. Plus, they disperse better throughout. We’ll use a portion of the marshmallows in the melted mallow mixture, but saving some to put in at the end helps keep these colorful Rice Krispie treats nice and soft! 
  • Kosher Salt: The kosher salt helps balance out the sweetness. Fruity Pebbles cereal is really sweet, so adding that bit of salt really helps! 
  • Fruity Pebbles Cereal: Whoever thought of Rice Krispie treats with Fruity Pebbles is a genius! It’s such a fun twist on the classic treat. 

Step-by-Step Instructions

  1. Melt the butter and marshmallows. In a large pot over medium-low to low heat, melt the butter and 8 cups of the marshmallows. Once the marshmallows are just melted, stir in the salt and vanilla. 
  1. Mix in the Fruity Pebbles cereal. Remove the pot from the heat and stir in the cereal. Mix until the cereal is completely coated in the marshmallow mixture. 
  1. Add extra marshmallows. Stir in the remaining 2 cups of mini mallows.
  1. Place in prepared pan. Spoon the Fruity Pebble Rice Krispie Treats into an 8×8-inch pan lined with foil and sprayed with cooking spray. Lightly press the mixture into the pan. Sprinkle with the additional 1/4 tsp of kosher salt (if desired). Let set.

Recipe Tips

Kosher salt is a bigger salt crystal than table salt, so be sure to adjust your measurements accordingly. (If using table salt, use half the amount called for in Kosher salt.) The Kosher salt is important because it really enhances the flavor of the recipe. 

I used an 8×8-inch pan because I wanted a thick treat.

My biggest tip is to just gently place the mixture into the pan. I barely even press the mixture down. All you want to do is spread the mixture so it lays evenly in the pan. You do NOT want to pack it in or the treats will be dense and hard. 

Gently rub butter onto your hand and then use your hand to press the mixture into the pan to prevent sticking. The mixture might be hot so be careful!

Make Ahead, Storing, and Freezing

If making ahead of time, store the treats in an airtight container or Ziplock bag with the air pressed out of it. It’s important that the treats be store in something that can be airtight so the treats don’t get hard. 

Store at room temperature in an airtight container for 2-3 days. Do not store the Fruity Pebble Rice Krispie Treats in the fridge or they will go hard and won’t soften at room temperature. (Same with freezing!)

FAQs

Why are my Rice Krispie treats hard?

Check your cereal and marshmallows. Were they expired? Did you over cook the mixture? Using mini marshmallows helps combat this because they melt quickly so your mixture isn’t on the stove for long. Big or regulars marshmallows will take longer to melt, meaning your pot will be on the heat longer. Did you pack them into your pan? Remember to lightly place them into the pan and not pack. 

What size marshmallows do you use?

I use the mini marshmallows! They disperse more easily and melt quicker, meaning your mixture won’t be at risk of over cooking from being on the stove longer.
