Ingredients You’ll Need
This recipe keeps things blissfully simple, letting just a handful of ingredients shine. Each one plays a unique role in delivering the unforgettable taste, texture, and signature look of the Fruity Pebbles Rice Krispie Treats Recipe.
- Fruity Pebbles cereal (6 cups): The star of the show, these rainbow rice crisps lend color, crunch, and an irresistible fruity flavor.
- Unsalted butter (1/4 cup): This creates a rich, melt-in-your-mouth base for the treats—make sure it’s unsalted to control sweetness.
- Mini marshmallows (1 package, 10 ounces): For that gooey, chewy texture that binds everything together and creates pockets of sweet softness.
- Vanilla extract (1/2 teaspoon): Just a splash amps up the cozy, comforting aroma and deepens the flavor.
- Pinch of salt (optional): A sprinkle of salt perfectly balances out all the sweetness for a more rounded bite.
How to Make Fruity Pebbles Rice Krispie Treats Recipe
Step 1: Prep Your Pan
Start by generously greasing a 9×13-inch baking dish with butter or nonstick spray. This step is non-negotiable—you want those colorful bars to lift out with ease, no sticking or tearing! Set your pan aside and get ready for some stovetop fun.
Step 2: Melt the Butter
Grab a large pot and melt your butter over medium heat. Watch closely and give it a gentle swirl as it melts, enjoying that nutty aroma. The even heat helps the butter combine perfectly with those fluffy marshmallows up next.
Step 3: Add and Melt the Marshmallows
Toss in your entire bag of mini marshmallows, then stir continuously with a sturdy spatula. You want a smooth, glossy, molten mixture, completely lump-free. Take your time—patience here means extra gooey, dreamy treats later.
Step 4: Develop the Flavor
Once the marshmallows melt, remove the pot from heat and promptly stir in your vanilla extract and a pinch of salt (if you’re using it). That tiny addition brings out the depth and savory notes, making every bite a flavor bomb.
Step 5: Fold in the Cereals
Immediately pour in all 6 cups of Fruity Pebbles cereal. Gently fold with your spatula until the colorful rice crisps are totally coated in gooey marshmallow deliciousness. Work quickly—the mixtures set fast and you want every bit evenly blended!
Step 6: Press and Cool
Pour the mixture into your prepared pan. Use a buttered spatula or a piece of wax paper to gently press the mixture out to the edges. Don’t pack it too tightly—light hands keep these treats soft and lovely! Let it cool for about 30 minutes until set, then slice into perfect rainbow squares.
How to Serve Fruity Pebbles Rice Krispie Treats Recipe

Garnishes
Sometimes the simplest choices can make the biggest impression: try a generous drizzle of melted white chocolate, a light shower of extra Fruity Pebbles, or even some colorful sprinkles on top for extra festive flair. Each garnish adds another pop of color and a touch of whimsy that’s sure to wow guests.
Side Dishes
Pair your Fruity Pebbles Rice Krispie Treats Recipe bars with a cold glass of milk for the ultimate nostalgia fix, or serve them alongside a platter of fresh berries to add a juicy, tart contrast. They also look dazzling as part of a dessert table with other no-bake sweets and fruit dips.
Creative Ways to Present
Cut your treats into fun shapes with cookie cutters for birthday parties or special occasions, or stack them on lollipop sticks for a portable, party-perfect snack. Arrange in a rainbow pattern on a platter, or wrap individual squares in cellophane for colorful lunchbox surprises!
Make Ahead and Storage
Storing Leftovers
Keep any leftovers in an airtight container at room temperature for up to 3 days. Layer parchment or wax paper between squares to keep them from sticking together and to lock in their signature softness.
Freezing
Yes, you can freeze your Fruity Pebbles Rice Krispie Treats Recipe for up to one month! Wrap individual bars tightly in plastic wrap and then store in a zip-top freezer bag. Thaw at room temperature for about an hour and they’ll taste just as fresh and chewy as the day you made them.
Reheating
While these treats are best served at room temperature, if you want to enjoy them extra soft and gooey, place a square in the microwave for just 5–10 seconds. Be careful—they can get hot fast, but the marshmallow will be deliciously melty!
FAQs
Can I use regular marshmallows instead of mini?
Absolutely! Regular-size marshmallows work just as well—just measure out about 40 regular marshmallows or 10 ounces by weight, and let them melt all the way before proceeding.
What’s the trick for ultra-gooey treats?
For extra gooeyness in every bite, reserve 1 cup of marshmallows and stir them in at the very end, right after you add the cereal but before pressing into the pan. They’ll create soft pockets that are out of this world!
Do Fruity Pebbles get soggy in these bars?
Nope—when you follow this Fruity Pebbles Rice Krispie Treats Recipe, the cereal stays crisp and crunchy, especially if you don’t over-press them into the pan and eat them within a couple of days.
Can I make this recipe dairy free?
Definitely! Use a vegan butter substitute and check that your marshmallows are dairy-free. The results are just as vibrant and tasty.
How can I make them look extra festive?
Try pressing in extra cereal on top before the treats set, drizzle with colored candy melts, or cut out star or heart shapes. The fun presentation makes this Fruity Pebbles Rice Krispie Treats Recipe pop on any party table!
