Recipe Summary
Prep Time: 10 minutes
Cook Time: 5 minutes
Cooling Time: 30 minutes
Total Time: 45 minutes
Servings: 12–16 treats
Ingredients
4 tablespoons unsalted butter
1 (10-ounce) bag mini marshmallows, about 5½–6 cups
½ teaspoon vanilla extract
Pinch of salt
3 cups Fruity Pebbles cereal
3 cups Rice Krispies cereal
1 cup mini marshmallows, optional, for extra gooey treats
Nonstick cooking spray or softened butter for the pan
How to Make Fruity Pebbles Rice Krispie Treats
1. Prepare the Pan
Lightly grease a 9x13-inch baking dish with butter or nonstick cooking spray. For easier removal, you can also line the pan with parchment paper and lightly grease the parchment.
2. Melt the Butter
Add the butter to a large pot and melt it over low heat.
Keeping the heat low is important. High heat can make the marshmallows too hot and ultimately give you hard Rice Krispie treats instead of soft, chewy ones.
3. Melt the Marshmallows
Add the 10-ounce bag of mini marshmallows to the melted butter.
Stir constantly over low heat until the marshmallows are almost completely melted and smooth. Remove the pot from the heat.
Stir in the vanilla extract and a small pinch of salt.
4. Add the Cereal
Immediately add the 3 cups Fruity Pebbles and 3 cups Rice Krispies.
Gently fold everything together until the cereal is evenly coated in the melted marshmallow mixture.
For extra gooey treats, fold in another 1 cup of mini marshmallows at the very end. Because the mixture has cooled slightly, some of these marshmallows will remain partially intact and create little pockets of marshmallow throughout the bars.
5. Press Into the Pan
Transfer the mixture to your prepared baking dish.
Don't pack it down too firmly. This is one of the secrets to soft Rice Krispie treats. Lightly press the mixture into an even layer using buttered hands, a greased spatula, or a piece of parchment paper.
6. Let Them Set
Allow the Fruity Pebbles treats to cool at room temperature for about 30 minutes, or until they're firm enough to slice.
Cut into squares and serve.
Fruity Pebbles Rice Krispie Treat Variations
There are plenty of ways to turn this basic recipe into something different. Try drizzling the finished bars with melted white chocolate, adding colorful sprinkles, or pressing extra Fruity Pebbles onto the top.
For birthday parties, dip one end of each square in melted white chocolate and add sprinkles before the chocolate sets.
You could also make Fruity Pebbles cheesecake Rice Krispie treats by adding a cheesecake-inspired layer or drizzle. That variation fits especially well if you're looking for another cereal-and-cheesecake mashup.
How to Make Them Extra Gooey
The biggest mistake with cereal treats is cooking the marshmallows for too long. As soon as they're melted, take the pot off the heat.
For especially gooey Fruity Pebbles Rice Krispie Treats, you can also increase the marshmallows slightly. Use a 12-ounce bag instead of 10 ounces, or fold extra mini marshmallows into the cereal mixture before pressing it into the pan.
And resist the urge to smash everything into the pan. The harder you compact the cereal, the denser your finished treats will be.
Can I Make Them With Only Fruity Pebbles?
Absolutely. Replace the Rice Krispies with an additional 3 cups of Fruity Pebbles for 6 cups Fruity Pebbles total.
Using only Fruity Pebbles creates a sweeter treat with a stronger fruity flavor. The half-Fruity-Pebbles, half-Rice-Krispies version has a slightly more balanced flavor and classic crispy-treat texture.
How to Store Fruity Pebbles Treats
Store the treats in an airtight container at room temperature for up to 3 days.
Place parchment or wax paper between layers to prevent them from sticking together.
Avoid refrigerating them unless necessary. Refrigeration can make cereal treats firmer and less gooey.
Final Thoughts
Fruity Pebbles Rice Krispie Treats take the classic marshmallow cereal bar and make it brighter, fruitier, and even more fun. The combination of buttery marshmallows, crispy rice cereal, and colorful Fruity Pebbles makes this an easy dessert that looks impressive without requiring any baking.
Keep the heat low, don't overcook the marshmallows, and gently press the mixture into the pan for soft, thick, gooey Fruity Pebbles treats every time.
