Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

4 tablespoons unsalted butter
1 bag (10 oz) mini marshmallows
3 cups Fruity Pebbles cereal
2 cups Rice Krispies cereal
1/2 teaspoon vanilla extract (optional)
Pinch of salt

Directions

Melt the Marshmallows
I start by melting the butter in a large pot over low heat. Once the butter melts, I add the marshmallows and stir constantly until they’re completely melted and smooth. At this point, I stir in the vanilla extract and a pinch of salt for a flavor boost.

Add the Cereal
I remove the pot from heat and quickly fold in the Fruity Pebbles and Rice Krispies cereals, mixing until all the cereal is evenly coated with the gooey marshmallow.

Press Into the Pan
I transfer the mixture into a greased or parchment-lined 9×13-inch pan and gently press it down with a spatula or clean hands. I like to press just firmly enough to shape the bars without compacting them too much.

Cool and Cut
I let the treats cool for about 30 minutes at room temperature before slicing them into squares.

Servings And Timing

This recipe makes about 12 bars.
Prep time: 10 minutes
Cool time: 30 minutes
Total time: approximately 40 minutes

Variations

Sometimes I make these using all Fruity Pebbles for a more intense fruity flavor and color. I’ve also stirred in white chocolate chips or drizzled melted white chocolate on top for a sweeter finish. When I want to make them extra gooey, I save 1/2 cup of mini marshmallows to stir in at the end before pressing into the pan.

Storage/Reheating

I store them in an airtight container at room temperature for up to 3 days. If I want to keep them soft, I place a slice of bread in the container to maintain moisture. I don’t refrigerate these treats because it can make them too firm. Reheating isn’t needed, but if I want a warm, soft texture, I microwave a square for 5–10 seconds.

FAQs

Can I Make These With Only Fruity Pebbles?

Yes, I’ve made them with just Fruity Pebbles before—they’re sweeter and more vibrant that way. I like the mix with Rice Krispies for a more balanced texture.

How Do I Keep Them From Sticking?

I grease my pan with butter or nonstick spray and use parchment paper to lift them out easily. I also grease my spatula or hands slightly before pressing the mixture into the pan.

Can I Use Large Marshmallows?

Yes, I’ve used large marshmallows before—about 40 of them equal one 10 oz bag of mini marshmallows. I just make sure to stir a bit longer as they melt.

Are These Gluten-Free?

Fruity Pebbles are gluten-free, but some brands of Rice Krispies contain malt. I check the labels if I need a gluten-free version and use all Fruity Pebbles or certified GF puffed rice cereal.

Can I Add Mix-Ins?

Absolutely. I’ve added mini marshmallows, sprinkles, or even crushed freeze-dried fruit for added texture and color.

Conclusion

Fruity Pebbles Rice Krispies Treats are a colorful, chewy, and ridiculously fun dessert that I can whip up in no time. They’re the perfect combo of fruity sweetness and gooey marshmallow comfort. Whether I’m making them for a party, a lunchbox treat, or just because—I know I’ll be sneaking more than one bite.
