For best results, do not overmix the batter after adding the flour to keep the cupcakes tender, and make sure all dairy ingredients are at room temperature so they blend smoothly. If the cinnamon filling feels too runny, chill it briefly so it holds its place in the batter and creates more defined swirls. Allow the cupcakes to cool fully before frosting to prevent the cream cheese frosting from melting or sliding. You can make the cupcakes a day ahead and store them covered at room temperature, then frost just before serving, keeping any frosted leftovers refrigerated for food safety and best texture.
