In a large Container (with a lid) Place the 9 cups of Rice Chex Cereal.  In 3 Medium bowls, place 1 square of the White Chocolate Almond Bark in each bowl.  Using only one bowl at a time, place the bowl in the Microwave, and melt the White Chocolate, for about 1 minute, stopping to stir about every 15 seconds.  When the Chocolate is melted, remove it from Microwave, and add the Pink Food Coloring Gel, making a bright Pastel Pink.

From the Container with the 9 cups of Cereal; Add 1 cup of Cereal to the bowl.  Stir the Cereal, coating it in Pink Chocolate.  Pour the Pink Coated Cereal out onto a piece of Parchment Paper, and separate the Cereal pieces to allow the Chocolate to dry, or set.  Follow the same steps for the 2nd and 3rd bowls, using the Aqua Food Coloring Gel in one bowl, and the Purple Food Coloring Gel in the other bowl. and placing the coated Cereal pieces out on Parchment Paper.

While the coated Cereal is drying, make the Bunny Chow:  In a microwave-safe dish, add the 3 Squares of the White Chocolate Almond Bark, the Butter, and Peanut Butter, and microwave on high for about 1 minute.  Stir, and microwave about 30 seconds longer, or until the mixture is smooth, and can easily be stirred.  Remove the dish from the Microwave, and stir in the Vanilla.

Pour the mixture over the Cereal in the Container, and stir well to coat the Cereal in the mixture.   When coated, Add the Powdered Sugar, and using a large spoon, stir the mixture until coated in the Powdered Sugar.  Add more Powdered Sugar if needed, so that all the Cereal pieces are coated in Powdered Sugar.  Place the lid on the Container, and gently turn the mixture upside down a couple of times to mix well.  Allow the mixture to cool.

When cool, add the Pink, Aqua, and Purple pastel coated Cereal pieces to the Bunny Chow.  Add the Mini Marshmallows, then place the lid on the container, and gently turn upside down to mix.  Using a spoon, scrape the leftover Pastel Colored Chocolate from the Parchment Paper, and sprinkle it over the Bunny Chow.  Place the lid on the Container to store until time to serve. When ready to serve, place on a plate, platter, in a bowl, or in small individual serving bowls.  Serve, and Enjoy!
