In a large bowl, mix together cake mix (dry cake mix- don't include ingredients called for on cake mix box), vegetable oil, and eggs. Fold in white chocolate chips.
Drop by tablespoonfuls onto cookie sheet and bake for 6-9 minutes, making sure to not over bake them.
Remove cookie from oven and place on wire racks to cool. Mix icing together in a small bowl and drizzle over warm cookies (or you can wait until they have cooled down a little bit- whatever you prefer!).
