Fruity Pebble Rice Crispy Treats

Okay friends, cereal bars are NORMALLY just for kids…but these Fruity Pebbles treats sure got me! I love Fruity Pebbles, so I thought it would be yummy to swap them for Rice Krispies and boy am I glad I did!

These bars are now one of my favorite Rice Krispie treats variations, second only to this scotcheroos recipe and peanut butter Rice Krispie treats!

The addition of fruity cereal adds the perfect hint sweetness and is a fun way to jazz up a this marshmallow cereal treat. The easy no-bake dessert bars are perfectly gooey from the marshmallows, with a soft, thick and chewy texture!

Ingredient Notes

Rice krispies, fruity pebbles and marshmallows in pot.
  • Butter: While unsalted butter is usually the norm in baking, salted butter actually provides a nice balance with the sweet cereal.
  • Mini marshmallows: I used a 16 ounce bag of fresh mini marshmallows, equal to around 8-10 cups. Do not use marshmallow creme or fluff.
  • Fruity pebbles cereal: Original fruity pebbles, although if they have released any special flavors that works and I have used Cocoa Pebbles for a rich variation.
  • Rice Krispies: Original crispy rice cereal is best to use for these fruity pebbles rice crispy treats. If you want a sweeter bar, sub for more fruity pebbles.

How to Make Fruity Pebbles Treats

  • Melt butter and marshmallows. Melt butter in a large saucepan over medium-low heat then add 7-8 cups mini marshmallows and stir until your marshmallows are almost melted. Remove immediately from the heat.
  • Stir in cereal. Stir in both cereals to the melted marshmallows and add your remaining 2-3 cups of mini marshmallows. Stir gently until the cereal is completely coated with the marshmallow mixture. 
  • Press in 9×13 pan. Add fruity pebbles mixture to a baking dish lined with foil and press down with a spoon coated in butter or wax paper to compact and make an even layer. 
  • Cool and serve. Let your fruity pebbles treats cool before slicing, I find this usually takes about 30 minutes but you speed the process up and put the bars in the refrigerator to chill if you need them sooner.

Recipe Tips

  • Large marshmallows: Can be substituted when melting the marshmallows and butter but will need to be cut into pieces when folded in with the cereal.
  • Line pan. For easier removal, line your baking dish with foil or parchment paper and then butter or spray the foil with cooking spray. This keeps the marshmallows from sticking to the pan.
  • Thickness. For thinner bars, use a 9×13″ pan. For thicker bars, use a 9×9″ pan.
  • Low heat. To avoid bars that are hard as a rock, melting the butter and marshmallow low and slow over low heat is the key for the perfect fruity pebbles rice krispie treats.
  • Press into pan. To ensure that they are even and compact, push down the Fruity Pebbles marshmallow bars with a spoon coated in butter or wax paper.
  • Let cool. Before cutting into squares, let the bars cool completely so that they’ll hold their shape.
  • Cutting. I’ve found that a plastic knife works best when cutting this fruity pebbles treats recipe. Cut into 16-18 medium-sized squares, or 9-10 larger squares.

Storage Instructions

To keep them soft, store any leftover Fruity Pebbles marshmallow treats in an airtight container or zip top bag. They will stay fresh for up to 2-3 days if stored properly, although they never last that long at my house! :)
