Ingredients & Substitutions

Cereal: The multicolored Fruity Pebbles cereal makes this a fun and easy treat or snack to satisfy your sweet tooth! Of course, you could substitute regular rice cereal, or use a combination of the two to still get a little bit of color.

Marshmallows: This recipe calls for 10 cups of mini marshmallows. One 10-ounce bag of miniature marshmallows yields 6 cups, so you will need two bags. Or, make your own homemade marshmallows to use! If you only have regular-sized marshmallows, you will need about 77 marshmallows to equal 10 cups of mini.

Butter: Unsalted butter is the best choice when making these bars. Salted butter could affect the sweetness of the bars, making them too salty.

Can I Use a Different Sized Pan?

Certainly! If you prefer thicker Rice Krispie bars, you can use an 8×8-inch pan (as I did in this recipe). However, if you prefer thinner bars or want to make more of them at once, you can use a 9×9-inch or 9×13-inch baking dish. It’s important to note that the larger the pan you use, the thinner the bars will be, as the mixture will be spread out over a greater surface area.

How to Store Fruity Pebbles Treats

There are a few ways to store these treats. Here are a few options:

  • Room Temperature: The bars will last 3-4 days when stored in an airtight container at room temperature.
  • To Refrigerate: Store the cooled bars in an airtight container for up to a week in the refrigerator.
  • To Freeze: After letting the bars cool completely, wrap them in plastic wrap with another layer of aluminum foil. Store them in a freezer-safe container for 3-4 months (although best enjoyed within a month of freezing).

Fruity Pebbles Treats are soft and chewy no-bake bars made with mini marshmallows and a generous amount of colorful crispy rice cereal.

Ingredients

  • 5 tablespoons unsalted butter
  • 10 cups (500 g) mini marshmallows, divided
  • 6 cups (216 g) Fruity Pebbles cereal

Instructions

  • Spray an 8×8-inch baking dish with nonstick cooking spray. Set aside.
  • In a large pot over medium heat, melt butter.
  • Add 8 cups of marshmallows, frequently stirring until melted. Once melted, remove from heat.
  • Using a clean rubber spatula, fold in the Fruit Pebbles cereal. (I like to spray the spatula with nonstick spray to prevent sticking.) Stir until well-coated.
  • Fold in the remaining marshmallows and transfer the mixture into the prepared baking dish. Press into an even layer.
  • Allow the bars to cool to room temperature before cutting and serving.
