Make the batter: Reduce the oven to 325°F. Using a stand mixer fitted with a paddle attachment or a hand mixer, beat the softened cream cheese, eggs, sugar, sour cream, vanilla, and salt until smooth and creamy on medium-high speed. Tip: For a softer, silkier texture, replace half the sour cream with heavy cream.
2 8oz packages cream cheese, 2 eggs, ½ cup sugar, ⅔ cup sour cream, 1 teaspoon vanilla extract, ¼ teaspoon salt
