For a richer flavor, consider using brown butter instead of melted butter in the cake batter. Be careful not to overbake the cake, as it will become dry and difficult to roll. The spiced cream filling can be made ahead of time and stored in the refrigerator for up to 24 hours. Garnish the finished cake roll with a dusting of powdered sugar, a sprinkle of chopped nuts, or a drizzle of melted chocolate for an extra touch of elegance.
