Marshmallow Fruity Pebble Treats

Soooo not my recipe, but so yummy I had to share!

1/2 stick of butter
10.5 oz pk of mini marshmallows
11 oz pk fruity pebbles (About 8 cups)

Melt the butter in a large sauce pan over low heat. When the butter has melted, add the marshmallows. Stir until melted. Remove from heat and add cereal, 2 cups at a time. When it's all mixed together, put the mixture into a greased 13x9 dish. Use a piece of plastic wrap or wax paper to press it down. Let it cool, then cut into squares and enjoy!
