Bake Me a Cake as Fast as You Can

Mr. Bartin needs your help in baking the three-layer cake. He knows the ingredients for making a one-layer cake, but he does not know what ingredients he needs for the three-layer cake.

Can you please help Mr. Bartin by helping him add the amounts of each ingredient?

The original one-layer recipe calls for: 2 and 1/2 cups of flour, 3/4 cup of sugar, 2/3 cup of oil, 1/4 cup of water, 2 eggs, and 3 teaspoons of vanilla extract.
