For best results, use a good-quality culinary matcha, as lower quality can taste bitter and dull in color; always sift the matcha and powdered sugar to avoid lumps in the batter and frosting. If your kitchen is warm, chill the frosting for 10 to 15 minutes to help it firm up before piping. Do not overmix the batter once the wet and dry ingredients are combined, as this can make the cupcakes dense rather than light and fluffy. You can adjust sweetness by slightly reducing the sugar or balancing with a pinch more salt. Store frosted cupcakes in an airtight container at room temperature for up to one day or refrigerate for up to three days, bringing them back to room temperature before serving for the best texture and flavor.
