The Lady Baltimore cake was popularized by the Owen Wister (1860-1938) novel Lady Baltimore (1906). Wister’s novel took place in fictional Kingsport, a substitute name for Charleston, South Carolina. The Woman’s Exchange is mention in the novel: Charleston had a Woman’s Exchange since 1885. The Woman’s Exchange tearoom (run by Florence and Nina Ottolengui) was named the Lady Baltimore Tea Room to capitalize on the popularity of the novel and the famous cake.
 
The “Lady Baltimore Cake” is first cited in print not from the 1906 novel, but from an 1889 Ladies’ Home Journal. A 1903 Greenville (SC) cookbook also features a Lady Baltimore cake recipe. The mystery of the origin of the cake and how it got its name (there are several people who were called “Lady Baltimore” in the 1500s-1700s, well before the cake was first made) still persists, but most food historians agree that the cake has no connection with the city of Baltimore, Maryland.
 
The Lady Baltimore is a three-layered white cake with white frosting, and with nuts, raisins, dates and figs often used as a filling. The “Lord Baltimore cake” is cited in print from 1910 and is a three-layered yellow cake with a filling of macaroon crumbs. The Lady Baltimore cake uses egg whites; the Lord Baltimore cake uses egg yolks.

Wikipedia: George Calvert, 1st Baron Baltimore
George Calvert, 1st Baron Baltimore (c. 1580 – 15 April 1632) was an English politician and coloniser. He achieved domestic political success as a Member of Parliament and later Secretary of State under King James I, though he lost much of his political power after his support for a failed marriage alliance between Prince Charles and the Spanish royal family. Rather than continue in politics, he resigned all of his political offices in 1625 except for his position on the Privy Council and declared his Catholicism publicly. He was granted the title of 1st Baron Baltimore in the Irish peerage upon his resignation.
 
Calvert took an interest in the colonization of the New World, at first for commercial reasons and later to create a refuge for English Catholics. He became the proprietor of Avalon, the first sustained English settlement on the island of Newfoundland. Discouraged by the climate and the sufferings of the settlers there, Calvert looked for a more suitable spot further south and sought a new royal charter to settle the region that was to become the state of Maryland. Calvert died five weeks before the new charter was sealed, leaving the settlement of the Maryland colony to his son Cæcilius. His son Leonard Calvert was the first colonial governor of Maryland. Historians have long recognized George Calvert as the founder of Maryland, in spirit if not in fact.

Baltimore City Paper (June 28, 2000)

by Brennen Jensen
Here’s the question: Who (or what) was Lady Baltimore? Well, first of all, there were Anne and Joan Calvert, the first and second wives of George Calvert, the first Lord Baltimore (circa 1580-1632). There is also a Lady Baltimore cake (an obscenely sweet affair featuring raisins and nuts) and a Lady Baltimore cruise ship that takes tourists puttering about the harbor. Additional poking around turned up a Lady Baltimore hibiscus, silver pattern, novel, and brand of luggage. (A Web search on “Lady Baltimore” even coughed up a porno site offering “free pissing panty lady pics”—but enough said about that.)

Lord Baltimore Cake is the peer of the long-popular Lady Baltimore Cake. it is a rich cake made rich by the use of egg-yolks. When planning to use this recipe one must also plan for the use of the whites of the egg. Not a difficult task, is it> Kisses, meringues, angel cake, prime-whip and bride’s cake come quickly to mind. Cream one-half cupful of butter and add gradually, while beating constantly, one cupful of sugar; then add the yolks of eight eggs, beaten until thick. Mix and sift one and three-fourths cupfuls of bread-flour with three teaspoonfuls of baking-powder. Add to first mixture alternately with one-half cupful of sweet milk. Flavor with two teaspoonfuls of vanilla and beat two minutes. Turn into three buttered and floured seven-inch-square tins and bake in a moderate oven. Put between layers Lord baltimore Filling. For the filling add to a boiled frosting (when ready to spread) one half a cupful of macaroon powder (macaroons dried in the oven and rolled or pounded), one-fourth of a cupful of blanched and chopped almonds, one-fourth of a cupful of chopped pecans, twelve candied cherries cut in small pieces, two teaspoonfuls of lemon-juice, one and one-half teaspoonfuls of vanilla and one teaspoonful of orange-extract.
 
Now cover top as well as sides with boiled frosting flavored with vanilla and garnish with a border of halves of cherries and diamond-shaped pieces of angelica, alternating the two.

FOOD; Rich and Famous
By JULIA REED
Published: April 21, 2002
In ‘‘Lady Baltimore,’’ Owen Wister’s ornate 1906 novel of American manners set in the post-Civil War South, the protagonist, John Mayrant, is engaged to a ‘‘steel wasp’’ of dubious background. (She is from either Natchez or Mobile; her father, a Confederate general, is said to have fled the Battle of Chattanooga.) She smokes, drinks highballs and consorts with other men, including a New York banker she uses to investigate the magnitude of her future husband’s fortune. However, in the eyes of the narrator, the gravest of her sins is that she pretends to be so financially strapped that the prospective groom must arrange the details of the wedding himself. This includes ordering the cake—a Lady Baltimore—from the Woman’s Exchange tearoom.
(...)
It is no wonder that this cake plays such a key role in the novel. It is really, really good, a fact the narrator, a Yankee who eats a piece for lunch almost every day, comments on with frequency. (“Oh, my goodness! Did you ever taste it? It’s all soft, and it’s in layers, and it has nuts—but I can’t write any more about it; my mouth waters too much.”) It turns out that there really was a Woman’s Exchange in Charleston, and legend has it that Owen Wister was served a piece of the cake there by its creator, Alicia Rhett Mayberry. But in the years since, its popularity has grown far beyond that city. A light, three-layer ‘‘silver’’ cake (meaning that it is made with egg whites instead of yolks), it has a filling containing dried figs, pecans, raisins and a bit of brandy or sherry. It is indeed grand enough for a wedding, and its fame spawned a Lord Baltimore cake (made with yolks instead of whites, and whose filling contains macaroon crumbs, toasted almonds and candied cherries.)
 
No one can tell me why Mrs. Mayberry, a native of Charleston, named the cake Lady Baltimore, but there was such a woman. Her name was Joan Calvert, second wife of George Calvert, the first Lord Baltimore, who founded the first religiously tolerant colony in North America (Avalon, a refuge for Catholics fleeing English penal laws, on the southern coast of Newfoundland) and whose heirs founded St. Mary’s City, the first settlement in what is now Maryland.

400 Star-Spangled, Razzle-Dazzle Recipes for America’s Best Loved Desserts

Pg. 150:
Lady Baltimore Cake
Owen Wister immortalized this dessert in his 1906 romance Lady Baltimore. Legend has it that Wister first tasted this cake at Charleston’s Lady Baltimore Tea Room, managed by the Misses Florence and Nina Ottolengui. Some claim that these ladies dreamed up the recipe, but others insist that Lady Baltimore cake is simply an ingenue version of the older Lane cake, created in Clayton, Alabama, in 1888. Some frost between the layers and frost on top, but leave the sides of the cake bare. Others frost the whole cake. Despite these turf battles, this cake is a winner. The white cake can be doubled, tripled, or quadrupled and will still taste winderful, which makes it perfect for celebratory wedding cakes. Frosted with a fantasty of sweetened Italian meringue blended with sherry-soaked dried fruits and nuts, this cake is adapted from one in the 1973 edition of the Joy of Cooking by irma S. Rombauer and her daughter, Marion Rombauer Becker.

Lady Baltimore Cake
This cake comes with a story. Alicia Rhett Mayberry, a southern belle in Charleston, South Carolina, baked this glorious dried fig, fruit, and nut-filled tiered cake for novelist Owen Wister, who was so enamored of the delicious confection that he described it in a 1906 novel he titled Lady Baltimore, Food historian Evan Jones writes that the original recipe may also have become the property of Florence and Nina Ottolengui, who managed Charleston’s Lady Baltimore Tea Room for over twenty-five years. As the story goes, each year they shipped Owen Wister a cake as “thanks” for helping make their cake famous. As Jean Anderson writes in the American Century Cookbook, the original Lady Baltimore Cake was a yellow cake that was made with whole eggs. More recent versions are silver cakes that are made with egg whites. One of the earliest silver-white recipes appears in the 1922 Good Housekeeping’s Book of Menus, Recipes and Household Discoveries, which uses rose extract for flavoring. Most recipes for Lady Baltimore Cake use either an old-fashioned boiled frosting or a seven-minute icing.
