These polka-dot cupcakes are vanilla based and flavored with orange zest. You can make it ahead of time and can last up to one week but make sure that you keep in the freezer; it can last overnight at room temperature. Once you have decorated them with the cream cheese icing, you can keep them at room temperature for only up to three hours. Surely these delicious cupcakes won’t last long on tray and once your visitors won’t stop at one as soon as they taste these polka-dot cupcakes.
