For best flavor, use fresh lemons and fine zest to avoid bitterness, and be careful not to overmix the batter after adding the flour to keep the cupcakes tender. Ensure all refrigerated ingredients are at room temperature so the batter emulsifies smoothly and rises evenly. Let the cupcakes cool fully before frosting or the butter-based frosting will melt and slide. If your frosting seems too thick, add cream a teaspoon at a time; if too thin, add a little more powdered sugar. Store frosted cupcakes in an airtight container at cool room temperature for up to 2 days, or refrigerate for slightly longer keeping in mind that chilling will firm the frosting.
