For best orange flavor, use fresh orange juice and zest, avoiding the bitter white pith when zesting; ensure all cupcake ingredients (except cream and filling) are at room temperature so the batter mixes smoothly and rises evenly. Do not overmix once the flour is added, or the cupcakes can turn dense instead of fluffy. If your frosting seems too soft, chill it for 10–15 minutes or add a few extra tablespoons of powdered sugar until it holds peaks. These cupcakes keep well covered in the refrigerator for up to 3 days; let them sit out for 15–20 minutes before serving so the texture and creamsicle flavor are at their best, and feel free to garnish with extra orange zest or a small orange slice for a bright, fresh look.
