["In a large mixing bowl, blend 3/4 of the dry mashed potatoes with just enough water to make them very thick. Add a little yellow food coloring if you wish to emulate a yellow cake.", "Spray a very large rectangular baking pan with cooking spray and transfer the potatoes to it, spreading the top (which will soon be the bottom) flat with a spatula.", "Bake at 375 degrees for about 45 minutes. Allow to cool for at least 30 minutes so you can handle the pan.", "Transfer the baked mashed potatoes to a hard flat surface (such as very stiff white cardboard or a baking sheet) by placing the hard surface on top of the pan and carefully flipping it over so that the \"cake\"" is transferred to the hard surface. You may need a little help with this. (I would not recommend making this cake with a bundt pan
