Using 1 tbsp of melted butter and a pastry brush, brush the inside of the pan. Make sure to get into every crease, especially if your pan has a detailed design. And don't forget to brush around the center ring! Once greased, sprinkle a few tbsp of granulated sugar into the pan, and gently tap while turning it. Do this until every inch of the inside is coated with sugar. Once you've done that, set it aside until you're ready to pour in your batter. While you can use nonstick spray, we recommend using a pastry brush and softened butter. Doing so ensures you get an even coating of butter which helps the cake not to stick.
