Fruity Pebbles Treats
I love regular Rice Krispies treats, but I also enjoy using different kinds of cereal in the same no bake dessert. One of my all-time favorite twists is these cinnamon toast crunch bars.
This month, while I was at the grocery store, I noticed that Fruity Pebbles were on sale, so naturally, I brought home a box. With St. Patrick's Day just around the corner, it's the perfect time for rainbow marshmallow treats!
The bright, colorful cereal adds a fun element to the crispy bars, and who can resist that fruity flavor? Just one whiff of the cereal box takes me back to my childhood.

Main Ingredients
This easy recipe requires only three simple ingredients. You can try different variations using your favorite cereal. The recipe card below provides the amounts and complete instructions.
- Butter: Unsalted or salted butter is acceptable in this recipe, so use whatever you have.
- Marshmallows: This is the glue that holds the bars together. I like mini marshmallows because they melt faster. I also enjoy adding extra marshmallows to the mix for extra gooey pockets.
- Fruity Pebbles Cereal: Any store brand of fruity cereal will work. For a chocolate twist, use Cocoa Pebbles.
How To Make Fruity Pebble Rice Crispy Treats
These simple fruity pebbles treats can be made quickly. Just melt, stir, and press them into a pan. The hardest part of the recipe is waiting for everything to cool before enjoying it.
Melt the butter and marshmallows together. Place the butter and mini marshmallows in a large pot over low heat. Stir until melted and smooth, then remove from heat.
Gently stir in the cereal. Pour the Fruity Pebbles cereal into the marshmallow mixture, then gently stir until everything is coated.
Add more gooey marshmallows. Once the cereal is coated, add one more cup of mini marshmallows and stir gently.
Press it into the pan. Spoon the mixture into a prepared baking dish and then gently press down. Use a buttered spatula or a piece of wax paper to do this.
Storage Recommendations
Allow the treats to cool completely before cutting them into squares. Then, transfer them to an airtight container and keep them on the counter at room temperature for 2-3 days.
BruCrew Tip: Place a piece of parchment paper between layers so they do not stick together.
Tips and Tricks
- Want thicker bars? Press the mixture into an 8x8 pan and cut into 12 squares.
- Butter your pan to prevent the treats from sticking to the bottom. You can also line the pan with parchment paper or foil to make it easier to lift the treats out.
- Use fresh ingredients. Do not use the stale bag of marshmallows in the back of your pantry. Fresh marshmallows taste better and make softer cereal treats.
- Melt the butter and marshmallows over low heat. The lower heat will keep the marshmallow goo from creating treats that set up hard.
- Spray your hands with nonstick baking spray or spread them with butter to prevent the mixture from sticking to you. You can also use parchment paper to press everything in without making a mess.
- Press the cereal mixture firmly yet gently into the pan. Pressing too hard can make the treats hard and crunchy.
FAQs
Heat the butter and marshmallows in a large microwave-safe bowl for 60 seconds. Stir, then heat for 15-30 seconds if needed. Add the cereal and stir until coated, then press into a pan.
Using old ingredients and packing the mixture in the pan can affect how your treats come out. Also, the bars will be harder if you melt the marshmallows and butter on high heat.
