For best flavor, use freshly grated orange zest and juice, as bottled juice can make the frosting less vibrant and sometimes too thin; make sure all cold ingredients (like egg and milk) are at room temperature so the cupcakes rise evenly and stay tender; avoid overmixing once the flour is added to keep the crumb soft; if your kitchen is warm, chill the frosting for a few minutes before piping so it holds its shape; and store cupcakes in an airtight container—at room temperature for up to 2 days or in the refrigerator for 3–4 days, allowing them to come back to room temperature before serving for the best texture and flavor.
