For best results, ensure your butter and eggs are at room temperature to create a smooth, well-emulsified batter that bakes up light and tender; avoid overmixing once the flour is added to prevent dense cupcakes, and check doneness a minute or two early since ovens vary. If your frosting seems too thick, add milk a teaspoon at a time; if it’s too thin, add a little more powdered sugar until it holds soft peaks. Let the cupcakes cool fully before frosting or the butter in the frosting may melt and slide off. You can bake the cupcakes a day ahead and store them covered at room temperature, and frost shortly before serving; decorated cupcakes keep well for 1–2 days in an airtight container away from heat and sunlight.
