For the best results, ensure that both the butter and mascarpone cheese are at a consistent room temperature before starting. This will help the frosting achieve a silky-smooth texture. If you prefer a sweeter frosting, gradually add more powdered sugar, 1/4 cup at a time, until you reach your desired sweetness. This frosting can be stored in an airtight container in the refrigerator for up to 3 days. Before using, bring it back to room temperature and re-whip it briefly to restore its smooth consistency.
