Rainbow Rice Krispie Treats with Fruity Pebbles and marshmallows are the best no-bake dessert for birthdays, Easter, St. Patrick’s Day and so much more. Soft, sweet, gooey, and absolutely delicious.
Rainbow Rice Krispie treats are the perfect combination of Rice Krispies, Fruity Pebbles, and marshmallows. Ava and I played with the ratios until we ended up with the perfect balance of cereals to marshmallow in these irresistible sweet treats -all for a great cause.
Doctors and researchers are making progress yet only 4% of the money raised for cancer research goes to pediatrics. My food blogger friends and I develop recipes to raise awareness and money for the fight against pediatric cancer. We raise thousands each year and some amazing and generous brands have partnered with us to match our donations.
These fun rice Krispie treats were my contribution to an amazing cause. I’ve played with the ratios of cereal to marshmallows many times and these are definitely the best. Each square is sweet, thick, and super marshmallowy.
Ingredients //
- Butter: helps achieve a soft, pleasant texture as well as prevents the squares from sticking to the pan. Since there is salt in this recipe, use unsalted butter.
- Mini Marshmallows: You’ll need about 3 bags -the fresher the better.
- Rice Krispies: or a comparable off-brand. No one will ever know the difference.
- Fruity Pebbles: not only add color, but also some subtle citrus flavor.
- Kosher Salt: Don’t skip the salt. I know it seems counterintuitive to add salt to sweet, but it enhances the flavor and keeps the treats from being too sweet (because yes, that is possible).
- Vanilla: enhances the sweet and sugary flavors making Rice Krispies treats everyone’s favorite snack.
- Recommended Equipment: For this recipe, a 9″ x 13″ baking pan, parchment paper, cooking spray, large Dutch oven or pot, heavy spoon, and an offset spatula are recommended for success.
How to Make // The Steps
How To Make Rice Krispie Treats with Fruity Pebbles
Step 1: Prep baking pan:
Line a 9″ x 13″ baking pan with parchment paper and then spray the parchment paper with cooking spray. Set aside.
Step 2: Melt butter and marshmallows:
In a large Dutch oven or pot, add butter and melt over low heat. Next, add two bags of marshmallows, stirring continuously until smooth and melted. As soon as the marshmallows are melted, remove the pot from the heat and then stir in the salt and vanilla.
Step 3: Mix with cereals and remaining marshmallows:
To the melted marshmallow mixture, add the Rice Krispies, Fruity Pebbles, and the last bag of marshmallows. With a sturdy spoon, stir until the cereal is evenly dispersed throughout the marshmallow.
Step 4: Press mixture into the pan to set:
Transfer the mixture to the prepared pan. Coat an offset spatula with cooking spray and use it to gently spread the mixture in the pan in an even layer. Allow the mixture to cool completely and set in the pan (about one hour) before slicing into squares.
Tips & Tricks //
- I like adding the third bag of marshmallows in with the cereal once the pot is off the heat. The residual heat melts them just enough to be sticky yet still hold some shape.
- If you do not have an offset spatula, you can use your clean hands to press the mixture into the pan. Spray your hands with a bit of cooking spray to keep the mixture from sticking.
- Don’t pack the mixture too tightly. If it is too compressed your bars might become hard as a rock.
- To cut clean squares. make sure the pan of Rice Krispies treats has cooled completely.

How to Store //
Storing: Rice Krispies treats have the best flavor and texture the same day they were prepared (unless you freeze them asap). However, they can be stored at room temperature in an airtight container for up to 3 days.
Make-Ahead and Freezer Options //
Freezing: After the treats have cooled, set and you’ve sliced them into squares, wrap each square in wax paper and store in a freezer-safe bag or container for up to 3 months.
FAQ
Yes. To dye the melted marshmallow mixture, simply fold in 1 to 2 drops of food coloring at a time until the desired color is reached.
To achieve the perfect texture, be sure you’re using fresh marshmallows melted over low heat, and do not pack the mixture in the pan too tightly.
Yes, but the colors will bleed together once melted, so I recommend replacing the third bag of marshmallows with a bag of mini-pastel marshmallows and adding them in with the cereals. They are supposed to be fruit-flavored so the taste will be a bit different.
