Spray an 8x8 baking pan with nonstick cooking spray. Set aside.

In a large microwave safe bowl, add butter and marshmallows. Heat on high heat for 60 seconds. Marshmallows will double in size.

Add cereal and mix well until color is coated on cereal. Press into the pan. Set aside.

For the white layer, repeat the blue layer directions, omitting the food coloring. Gently press into pan.

For the red layer, repeat the directions for the blue layer, and press into pan.

Let set for an hour so set up. Remove from pan and use a sharp knife to cut into 16 squares.
