10-Minute Fruity Pebbles Rice Krispie Treats
Fruity Pebbles Rice Krispie Treats are the brightest, happiest no-bake dessert you can make in a single pot. They come together in about 10 minutes, then set into chewy, colorful bars that taste like a mashup of buttery cereal squares and a bowl of childhood cereal.
A half-and-half mix of crispy rice and fruity flakes gives you the classic snap you love with a burst of rainbow in every bite. They hold their shape beautifully and stay soft for days.
Why These Treats Always Disappear First
I make a lot of cereal bars, but the ones with Fruity Pebbles are the batch that vanishes fastest. The color alone puts a smile on everyone’s face, and the fruit cereal adds a subtle sweetness that plain Rice Krispies miss.
The texture is exactly what you want: a slight crisp edge that gives way to a soft, marshmallowy center. You get the buttery richness of a classic treat with an extra layer of bright, nostalgic flavor.
They ask for zero baking, a handful of ingredients, and about five minutes of stirring. That means you can pull them together right before a party or a last-minute school snack with no stress at all.
Ingredients
- 4 tbsp unsalted butter: salted works too, just skip the pinch of salt later.
- 10 oz bag mini marshmallows: fresh ones melt the smoothest and give the best chew.
- 1 tsp vanilla extract: rounds out the buttery flavor without overwhelming the cereal.
- Pinch of salt: this little bit helps the marshmallow taste less flat.
- 3 cups crisped rice cereal: use any brand you like, but stick with plain unsweetened rice cereal.
- 3 cups Fruity Pebbles cereal: the star of the show, bringing all the color and fruity taste.
Variations / Substitutions
- Go full rainbow: skip the rice cereal and use 6 cups Fruity Pebbles for an even fruitier bar. They will be softer and more candy-like.
- Make them chocolatey: stir ½ cup mini chocolate chips into the melted marshmallow right before the cereal goes in. White chocolate chips are great too.
- Dairy-free option: swap the butter for a neutral tasting vegan butter stick. Most marshmallows are not vegan, so look for a plant-based brand if needed.
- Change the cereal: any crisp puffed grain works here. Try a mix of cocoa crisps and Fruity Pebbles for a chocolate-berry twist.

How to Make Fruity Pebbles Rice Krispie Treats
Step 1: Melt the Marshmallow Mixture
In a large pot over low heat, melt 4 tablespoons unsalted butter. Once melted, stir in the 10-ounce bag of mini marshmallows, a pinch of salt, and 1 teaspoon vanilla extract. Keep the heat low and stir often until the marshmallows are almost fully melted, about 3 to 4 minutes. Take the pot off the heat before the last few lumps disappear so the mixture does not overcook and turn stiff.
Step 2: Fold in the Cereals
Immediately pour in 3 cups of crisped rice cereal and 3 cups of Fruity Pebbles. Fold everything together with a rubber spatula until every flake and puff is coated in the glossy marshmallow. Work quickly but gently to keep the cereal from crushing, about 30 seconds of folding should do it.
Step 3: Press into the Pan
Scrape the sticky mixture into a greased 9×13 inch straight-sided baking pan. With a lightly buttered piece of parchment or wax paper, press the mixture firmly and evenly into the corners. Let the pan sit at room temperature for at least 30 minutes until the block is firm and slightly cool to the touch.
Step 4: Slice and Serve
Run a butter knife around the edge of the pan, then turn the whole slab out onto a cutting board. Use a sharp chef’s knife to cut the slab into squares, about 2-inch pieces give you 16 generous bars. Serve them piled on a bright plate while they are still fresh and chewy.
Tips for the Best Cereal Treats
- Low heat is your friend.: Too much heat makes the melted marshmallow seize up into a hard, stringy mess. Keep the burner on low and pull the pot off early.
- Press with a light touch.: Pushing too hard packs the bars into a dense, tough block. Just enough pressure to level the top keeps them tender.
- Fresh marshmallows matter.: A bag that has been sitting open in the pantry for weeks will give you dry, crumbly bars. Buy a new bag for the best texture.
- Clean cuts every time.: Spray your knife with a little nonstick spray or wipe it with a dab of butter between slices. This stops the sticky marshmallow from yanking the bars apart.
Storing Leftover Treats
- Room temperature:: Keep them in an airtight container for up to 3 days. Separate layers with wax paper so they do not stick together.
- Refrigerate:: Stored airtight, they keep for a week in the fridge. The texture will be a bit firmer, but they still taste great.
- Freeze:: Wrap individual bars tightly and freeze for up to a month. Thaw on the counter for about 15 minutes before eating.
Frequently Asked Questions
Can I use only Fruity Pebbles and skip the rice cereal?
Yes, you can. Use 6 cups of Fruity Pebbles. The bars will be softer, sweeter, and a little more fragile, but completely delicious.
How long do they take to set?
At room temperature, about 30 minutes. You can also pop the pan in the fridge for 10 to 15 minutes if you are in a hurry.
Can I add other mix-ins?
Absolutely. Mini chocolate chips, rainbow sprinkles, or toasted coconut all work well. Stir them in right after the cereal is coated so they do not melt too much.
Why did my marshmallow mixture turn grainy?
The heat was probably too high. Melt everything over low heat and take the pot off the stove while the marshmallows are still a little lumpy to keep the mixture silky.
