How to Make Homemade Fruity Pebbles Rice Krispie Treats
Prepare a 9×13-inch baking dish by coating it with nonstick spray or lining it with parchment. Lightly grease a large spoon or spatula as well to prevent sticking.
In a large microwave-safe bowl, combine the butter and marshmallows. Microwave on high for about 2 minutes, or until the marshmallows are puffed and the butter is melted.
Stir the mixture quickly and continuously until smooth and creamy. Immediately fold in the Fruity Pebbles cereal and stir gently until the cereal is evenly coated with the marshmallow mixture.
Transfer the mixture to the prepared pan and spread it into an even layer. Press down gently with a greased spatula or a piece of parchment to compact the treats without crushing the cereal too much.
Cover and let the treats set at room temperature for 3 to 4 hours before slicing into bars. Allowing them to rest helps them hold together when cut.
Tips for making Fruity Pebbles Rice Krispie treats
- Use fresh marshmallows for the smoothest melt and best texture.
- Work quickly while the marshmallow mixture is warm; it becomes firm as it cools.
- If the mixture seems too wet, add a little more cereal, one cup at a time, until you reach the texture you want.
- Place a sheet of parchment over the top before pressing to avoid sticky hands and to create a smooth surface.
- Let the treats rest fully before slicing so they stay intact. Greasing the knife makes cutting cleaner.
Variations
- Swap in Cocoa Pebbles for a chocolate-flavored version.
- For thicker bars, use a smaller pan (10×7) or double the recipe and bake in a 9×13 dish.
- Stir in 1/2 cup of unmelted mini marshmallows for extra gooey pockets and texture.
- To reduce sweetness slightly, mix half Fruity Pebbles and half plain Rice Krispies.
Storage Instructions
Store finished treats in an airtight container or a zip-top bag at room temperature for up to 2–3 days. They taste best the first day but remain soft for a couple of days if kept sealed.
Can I Use Large Marshmallows?
Yes. If you only have regular (large) marshmallows, cut them into quarters so they melt evenly. As a guideline, 1 cup of mini marshmallows equals about eight regular marshmallows, so this recipe calls for roughly 64 regular marshmallows if you replace all the minis.
