Whether or not you need to grease and flour a Wilton cake pan ultimately depends on the specific recipe you are using. Generally, it is a good practice to lightly grease and flour the cake pan to ensure that the finished cake does not stick to the pan when it is time to remove it. This can be particularly important if your recipe contains a lot of fat or sugar, as these ingredients tend to make cakes more likely to stick. To do this, simply use a small amount of cooking spray or butter and evenly coat the inside surface of the pan. Then, sprinkle a thin layer of flour over the greased surface, rotating and tapping the pan to ensure even coverage. Shake off any excess flour before adding your cake batter.
