Fruity Pebbles Cereal Bars with Rainbow Marshmallows

These cereal bars are so much fun. They are made like Rice Krispie treats with melted mini marshmallows but they are fruity and colorful. After the treat bars are prepared, we top them with colorful cereal marshmallows, gold sequins sprinkles, and green sprinkles! 

The “cereal marshmallows” are dehydrated mini marshmallows in a variety of colors. I’m linking to them on Amazon as that’s the only place I have been able to find them. They are similar to the marshmallows you would find in a cereal like Lucky Charms.

I am also linking to the gold sequins sprinkles on amazon. You might also be able to find them at a store like Michael’s or similar that sells a lot of cake decorating items.
