Take the 3 cups of sugar and melt in the pot. As it browns, carefully add 3 cans of water stirring constantly until it looks smooth. When smooth, pour to a bowl and let cool.
In a large bowl combine all your wet ingredients--sauce,eggs, oil, evaporated milk, vanilla and coconut. Slowly sift the flour together with the baking soda, and then blend all the ingredients together for about 3 minutes.
Grease your pan, and pour ingredients and then bake or steam for about an hour.
