How to make icing for a cake?

how do you make icing for a cake without wasting too much money? I made a cake and tried to make some icing, but it was too sweet and not as white as in the store.What can I do!? Does anybody know a good recipe?

2 cups powdered sugar (sifted)
1/2 teaspoon vanilla
2 tablespoons milk

Mix the powdered sugar with the vanilla and milk. Then add more milk a bit at a time until it is thin enough to drizzle over a cake. Once you've iced your cake, it's best to let it stand for one or two hours.

To make chocolate icing, add two tablespoons cocoa powder when you mix the powdered sugar and follow the rest of the recipe above.

Enjoy
