5 Ingredients in These Fruity Pebbles™ Treats

  • Unsalted Butter: The creamy foundation of these Fruity Pebbles™ marshmallow treats starts with butter—4 tablespoons, to be precise, setting the stage for a gooey delight.
  • Marshmallows: Packed with an extra punch of marshmallows, these treats stay perfectly sticky, needing one 10-ounce bag plus an additional cup of mini marshmallows for that ideal marshmallow-to-cereal ratio.
  • Vanilla Extract: Just a teaspoon of vanilla extract elevates these treats from tasty to tantalizing, infusing them with a subtle depth of flavor that makes all the difference.
  • Salt: A half teaspoon of kosher salt is the secret weapon that brings out the sweetness and complements the fruity flavors, proving that a little pinch goes a long way.
  • Fruity Pebbles™ Cereal: Six cups of colorful Fruity Pebbles™ turn the classic crispy treat into a rainbow of fruity flavor and fun texture, just as they do in this Fruity Pebbles ice cream recipe.

How to make Fruity Pebbles™ Marshmallow Treats

  1. Grease an 8×8 or 9×9-inch baking pan with butter or line it with parchment paper to prevent the treats from sticking. I take a sheet of parchment, cut the corners, place the paper in the pan, and spray it with oil. And I use these black clips to keep the sides down. These come in handy for other baking projects as well.

2. Start by melting the butter in a large saucepan over low heat. I use my 5.5-quart Dutch oven. Any similar size works great!

3. Once the butter has melted, add the bag of mini marshmallows to the saucepan. Stir constantly until the marshmallows have completely melted and combined with the butter. Remove the saucepan from heat, stir in vanilla and salt.

3. Add the Fruity Pebbles™ cereal to the marshmallow mixture. Stir well to ensure that all the cereal is coated with marshmallow goodness.

4. Pour in one cup of marshmallows and fold them gently into the mix. Transfer the mixture to the dish and gently press it down using a spatula or your hands. You may want to spray your hands with cooking spray so they don’t stick!

Tips and Tricks for the Best Fruity Pebbles™ with Marshmallow Treats

  1. Low and Slow: When melting your butter and marshmallows, keep the heat low to avoid burning. Slow melting ensures a smooth and even mixture, crucial for coating the cereal evenly.
  2. Fresh Marshmallows Matter: Use fresh, soft marshmallows for the best gooey texture. Older marshmallows can result in a harder, less pliable treat.
  3. Grease Your Hands and Utensils: To prevent sticking, lightly grease your hands and utensils (like the spatula) with butter or non-stick spray when pressing the mixture into the pan and cutting the treats.
  4. Don’t Over-Press: When pressing the mixture into the pan, do it gently. Over-pressing can make the treats too dense and hard.
  5. Cool Before Cutting: Allow the treats to cool and set completely before cutting them. This helps them hold their shape better and makes cutting easier.

Recipe Variations

  1. Chocolate Drizzle: Add a chocolatey touch by drizzling melted white or dark chocolate over the top of the set treats.
  2. Marshmallow Varieties: Use flavored marshmallows, like strawberry or vanilla, to add an extra layer of taste.
  3. Lemon Zest: Add some grated lemon zest to the marshmallow mixture for a zesty, citrusy flavor.
  4. Cereal Mix: Combine Fruity Pebbles with another cereal, like Rice Krispies or Cocoa Pebbles, for a multi-textured and flavored treat.
  5. Sprinkle Surprise: Add colorful sprinkles to the mix before setting, making them even more appealing to kids and perfect for parties.

Recipe Substitutions

  • For 4 tablespoons unsalted butter:
    • Use an equal amount (4 tablespoons) of margarine or a plant-based butter for a dairy-free or vegan option.
  • For 10-ounce bag mini marshmallows (plus 1 cup mini marshmallows, divided):
    • Vegan marshmallows can be used as a vegan alternative.
  • For 1/2 teaspoon (2g) Diamond Crystal kosher salt:
    • If using table salt, use half the amount by volume, as table salt is denser. For the same weight (2g), it would be equivalent.
  • For 6 cups Fruity Pebbles Cereal:
    • Any crispy rice cereal, especially a gluten-free variety if needed.
    • Other flavored cereals like Cocoa Pebbles or Rice Krispies can be used for a different taste profile.

Storage Tips

  1. Room Temperature Storage:
    • Store the treats in an airtight container at room temperature.
    • They typically last well for up to 3 days when stored this way.
  2. Avoid Refrigeration:
    • Refrigerating these treats can cause them to become hard and lose their ideal texture.
    • If you must refrigerate (due to a warm climate or added perishable ingredients), let them come to room temperature before serving for the best texture.
  3. Layering with Parchment Paper:
    • If stacking treats in a container, place sheets of parchment or wax paper between layers to prevent them from sticking together.
  4. Freezing for Longer Storage:
    • You can freeze these treats for up to 6 weeks.
    • Wrap them individually in plastic wrap and then place them in a zip-lock freezer bag or an airtight container.
    • Thaw at room temperature for a few hours before eating.
  5. Cutting Before Storing:
    • It’s often easier to cut the treats into squares before storing, as they can harden slightly and become more difficult to cut cleanly over time.
  6. Avoid Moist Environments:
    • Store them in a cool, dry place away from moisture, as humidity can make them soggy.

How to serve Fruity Pebbles™ treats

  1. Classic Squares:
    • Cut the treats into squares or rectangles for a traditional and easy-to-handle serving. This is great for grab-and-go convenience at parties or as snacks.
  2. Fun Shapes:
    • Use cookie cutters to cut the treats into different shapes like stars, hearts, or circles. This can be particularly appealing for children or themed parties.
  3. With Ice Cream:
    • Serve a square of the treat with a scoop of ice cream on top or on the side. The combination of cold ice cream and chewy treat is delightful.

  • 4 tablespoons unsalted butter
  • 10 ounce bag mini marshmallows plus 1 cup mini marshmallows, divided
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon (2g) Diamond Crystal kosher salt; for table salt, use about half as much by volume or the same weight
  • 6 cups Fruity Pebbles™ cereal


  • Line a 8×8 or 9×9 with parchment paper. Lightly grease the parchment. I always use a very light mist of nonstick spray. Set aside.
  • Melt the butter over low heat in a large pot or Dutch oven. Once melted, add the 10-ounce bag of marshmallows. Stir the mixture until the marshmallows are just melted. Stir in the salt and vanilla to combine.
  • Remove the pan from the heat, add the Fruity Pebbles™ cereal, and mix until evenly coated with the marshmallow mixture. Stir in the additional one cup of marshmallows.
  • Turn the mixture out into the prepared pan and, using a wooden spoon or spatula that has been coated in non-stick cooking spray, press the mixture into a packed, even layer. Do not pack it down with force. Lightly press down until it is secure in the pan.
  • Allow treats to set for at least 1 hour at room temperature and up to 1 day. Cover tightly if leaving out for more than a few hours.
  • Lift the treats as a whole out of the pan using the edges of the parchment paper. Cut into squares.
  • Cover and store leftover treats at room temperature for up to 3 days. To store, place in an airtight container, with sheets of parchment or wax paper between layers.


 Large Batch
  • 8 tablespoons (1 stick) unsalted butter
  • 2 bags (10 ounces each) marshmallows
  • 2 cups mini marshmallows (for extra gooeyness)
  • 2 teaspoons vanilla extract
  • 1 teaspoon diamond crystal kosher salt
  • 12 cups Fruity Pebbles™ cereal
Follow the instructions above, but spread the cereal treat mixture into a greased 9×13-inch pan. 
  • Marshmallows: You will need 2 (10-ounce) bags of miniature marshmallows for this recipe. You will only need a cup of the 2nd bag.
  • Omitting Extra Marshmallows: You can omit the extra marshmallows that get stirred in at the end if you wish. Don’t worry about altering the recipe – it’ll still be great.
  • Storing + Shelf Life: These are best eaten the same day you make them. But if you’ve got leftovers, keep them in an airtight container at room temperature, and they should be good for about 3 days. Wrapping them individually in plastic wrap before storing them can help keep them fresh.
  • Freezing: Wrap each in plastic wrap, put them in a freezer bag, and keep them for a few months. Or layer cut pieces in layers separated with parchment paper. When you’re ready to eat them, let them thaw at room temperature.
