Fruity Pebbles, marshmallows, white chocolate, and confetti sprinkles come together to make these Rainbow Krispie Treats — a quick and festive dessert perfect for St. Patrick’s Day.
If you want a colorful holiday treat that’s easy to make, these Rainbow Krispie Treats are for you. They’re bright enough for St. Patrick’s Day, come together quickly, and are loved by kids and adults alike. The idea is simple: swap Fruity Pebbles for the usual rice cereal in a classic krispie recipe, add extra marshmallows for gooey texture, and top with melted white chocolate and rainbow sprinkles for a festive finish.
These treats come together fast and require minimal equipment. Once the marshmallows are melted and folded with the cereal, press the mixture into a prepared pan, cover with melted white chocolate, and sprinkle on colorful confetti while the chocolate is still warm. Chill briefly, slice, and serve. I dare you to eat only one — they’re that irresistible!
My husband says he likes these even more than traditional rice krispie treats — the Fruity Pebbles add bright color and a fun fruity crunch that pairs perfectly with the sweet marshmallow and creamy white chocolate topping.
Rainbow Krispie Treats
Amber Brady
24 squares
Ingredients
- 4 Tbsp butter
- 1 ¼ to 1 ½ (16 oz) bags marshmallows (depending on how chewy you like your krispie treats)
- 6 cups Fruity Pebbles cereal
- 12 oz white chocolate chips
- 1 Tbsp coconut oil or shortening, for thinning
- Rainbow sequins / celebration confetti / rainbow sprinkles
Instructions
-
Grease a 13×9-inch baking dish with extra butter or nonstick spray.
-
In a large nonstick pot, melt 4 Tbsp butter over low-medium heat. Add marshmallows and stir constantly until fully melted and smooth.
-
Remove from heat. Fold in the Fruity Pebbles cereal until the marshmallow is evenly distributed and the mixture is well coated.
-
Transfer the mixture to the prepared baking dish. Press evenly into the pan using a buttered measuring cup or parchment to avoid sticking and protect your hands.
-
Melt the white chocolate chips with the coconut oil in a microwave-safe bowl in 30-second bursts, stirring between each interval until smooth and pourable.
-
Spread the melted white chocolate over the top of the krispie treats and immediately sprinkle with rainbow confetti so it adheres while the chocolate is warm.
-
Allow the treats to set for at least 1 hour before cutting and serving. Chilling in the refrigerator speeds up the process.
