Funfetti Rice Krispie Treats

Funfetti Rice Krispie Treats are one of my favorite no-bake desserts because they're colorful, look impressive, and come together in minutes. Soft marshmallow mixes with crispy cereal together while rainbow sprinkles, white chocolate drizzle, and cookie crumbles create a festive, party-ready treat. I make them for birthday parties, classroom treats, Christmas gatherings, and bake sales because they travel well and kids absolutely love them. Store them at room temperature for about 3 days or freeze for up to 2 months.

Equipment

Ingredients
 
 

  • ½ cup unsalted butter
  • 15 ounces mini marshmallows
  • 1 teaspoon vanilla
  • ¼ teaspoon salt
  • 6 cups Rice Krispies cereal
  • ½ cup rainbow sprinkles plus some for garnish
  • ½ cup white chocolate
  • ¼ cup golden Oreos crushed

Instructions
 

  • Line a 9×13-inch baking pan with aluminum foil and lightly coat with nonstick spray. Set aside.
  • In a large pot over medium-low heat, melt the butter. Stir in the vanilla and salt. Add 10 ounces of the mini marshmallows (reserve the remaining 5 ounces) to the pot. Stir constantly until melted and smooth.

  • Fold in the remaining 5 ounces of mini marshmallows and the rainbow sprinkles. Stir gently to distribute.
    ½ cup rainbow sprinkles
  • Press the mixture into the prepared pan using a greased rubber spatula. Spread evenly. Let cool at room temperature until set.
  • In a microwave-safe bowl, melt the white chocolate in 20–30 second intervals, stirring between each, until smooth.
    ½ cup white chocolate
  • Remove the bars from the pan. Drizzle with melted white chocolate, then sprinkle with crushed Golden Oreos, extra sprinkles, and remaining mini marshmallows. Allow the chocolate to set before slicing into squares.

Notes

Here are my best tips for consistently perfect Funfetti Rice Krispie Treats.
  • Use fresh marshmallows: Stale marshmallows won't melt smoothly and can make the treats hard. Fresh marshmallows provide a soft, stretchy texture.
  • Press gently: Use a greased spatula to press the mixture into the pan with light pressure. Pressing too hard makes the treats dense and hard instead of light and chewy.
  • Let the chocolate set completely: Wait until the white chocolate drizzle is fully hardened before cutting. This prevents toppings from smearing and allows clean slices.
  • Flash freeze for clean cuts: Freeze the uncut treats for 30 minutes before slicing. The cold helps you get perfect squares without the marshmallow sticking to your knife.
  • Storage pro tip: Wrap individual squares in plastic wrap before freezing so you can grab one at a time. They thaw in about 20 minutes at room temperature and taste fresh-baked.
  • Cake-batter variation: Melt butter completely, fold in 1 cup of dry funfetti cake mix with the cereal for a denser, cake-like texture, and use white chocolate chips instead of bar chocolate for smoother melting and drizzling.
