The Best Gooey, Fruit Treat

Okay friends, rice krispie treats are NORMALLY not my weakness…but these fruity pebbles treats sure got me! I love fruity pebbles, so I thought it would be yummy to combine the two. And boy, was that a great idea :)

These bars are now one of my favorite rice krispie treats variations, although this scotcheroos recipe with peanut butter and chocolate will always have a place in my heart, too.

Seriously the addition of the fruity cereal is SOO good! It adds the perfect hint of sweetness and is a fun way to jazz up the classic recipe. The bars are perfectly gooey from the marshmallows, with a soft and delicious texture that will leave you craving another bite. Trust me, this easy dessert is addicting!

Fruity Pebbles Treats Recipe Ingredients

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: You will need a 16 ounce bag of fresh mini marshmallows. That is equal to around 8-10 cups if you are measuring by volume.
  • Fruity pebbles cereal: Original fruity pebbles, although if they have released any special flavors that works, too!
  • Rice Krispies: Original crispy rice cereal is best to use for these fruity pebbles rice crispy treats.


  • All fruity pebbles. If you love fruity pebbles, feel free to replace the rice krispies cereal with the fruity cereal instead. They will be sweeter this way, but oh so delicious!
  • Cocoa pebbles. For a richer variation, sub fruity pebbles for cocoa pebbles.
  • Vanilla extract: Just a small amount adds additional flavor.

How to Make Fruity Pebbles Treats

This fruity pebbles treats recipe comes together quickly in only 15 minutes!

Step by step photo collage of 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.

Expert Tips

  • 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. Slowly melting the butter and marshmallows over low heat is what gives these bars that beloved gooey and soft texture. Low and slow is the key for the perfect fruity pebbles rice krispie treats.
  • Press into pan. To ensure that they are even and compact, push down 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. If you’d like to speed up the cooling process, try sticking the pan in the fridge for a bit.
  • Cutting. I’ve found that a plastic knife works best when cutting these fruity pebbles treats. This recipe will make enough for about 16-18 medium-sized squares, or 9-10 larger squares.

Can I use regular sized marshmallows?

That will work when you are melting the butter with the marshmallows, but you will need to cut them into pieces when you fold them in with the cereal otherwise they are too large.

Can I use marshmallow creme or marshmallow fluff?

While technically yes the texture will be different so I would advise not to use any marshmallow cream from a jar and use regular mini marshmallows instead.

Why did my fruity pebbles treats turn out hard?

If you melted your marshmallows over too high of a heat or left them over the heat for too long there is a risk that your bars will turn out hard as a rock.

How long can I store leftovers?

These never last past a day in my house but if you have leftovers you can store them at room temperature for 2-3 days in an airtight container.

Storage Instructions

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