Step-by-step instructions
- In a large pot, melt the butter over low heat.
- Add the mini marshmallows and stir continuously until fully melted and smooth.
- Remove from heat and blend in the vanilla extract. If you’re using salt, add it at this point.
- Gently fold in both the Rice Krispies cereal and Fruity Pebbles, ensuring every piece gets nicely coated in the marshmallow mixture.
- Transfer your mixture to a greased 9×13-inch baking dish.
- Using a spatula, gently press down the mixture. Be careful not to press too hard; you want your treats to stay light and chewy.
- Allow the treats to set at room temperature for about 30 minutes before slicing them into squares.
Best ways to enjoy it
Rainbow Rice Krispie Treats are perfect on their own but can also be dressed up for special occasions. Consider drizzling some melted chocolate over the top or sprinkling on colorful edible glitter for an extra festive touch. They pair beautifully with a scoop of vanilla ice cream or a tall glass of cold milk. If you’re feeling adventurous, serve them alongside fruit skewers for a fun dessert platter.
Storage and reheating tips
To keep your Rainbow Rice Krispie Treats fresh, store them in an airtight container at room temperature for up to a week. If you want to keep them for longer, you can freeze the squares for up to 3 months. Just make sure to wrap them well to prevent freezer burn. When you’re ready to enjoy them, let them thaw at room temperature—there’s no need to reheat.
Helpful cooking tips
To achieve the perfect texture, it’s essential not to over-press the mixture into the pan. This keeps the treats light and chewy. Additionally, if you find that the mixture is too sticky, lightly greasing your spatula can make pressing much easier. If you want to experiment with flavors, a touch of almond extract can add a delightful nutty note.
