“Snickerdoodles” are drop cookies topped with cinnamon sugar that are cited in print from at least 1889. The cookie is simple, but the origin of the cookie’s fanicful name is difficult to determine. James Beard and others believe a German or Dutch origin to “snickerdoodle,” possibly from “Schnecken noodles” (“Schnecken” = snail). “Snickerdoodles” have gone by many other colorful names, such as “snip doodles,” “kinkawoodles,” and “tangle breeches.”
   
“Snickerdoodles” were popular from Boston (New England) to Philadelphia (Pennsylvania Dutch areas) by about 1900.
 
 
Wikipedia: Snickerdoodle
A snickerdoodle is a soft sugar cookie rolled in cinnamon sugar. It has a characteristically crackly surface, and can be crisp or soft, depending on preference. They typically are easy to make. Some variants include nutmeg, raisins, chocolate chips, or nuts. In modern recipes, the leavening agent is usually baking powder which, in baking, is most commonly used in cakes but not often in cookies.
 
Origins
Nobody is sure where either the cookie or its name originated. Various food historians have shown that biscuits and cookies similar to the Snickerdoodle have been recorded in the Ancient Roman era and Medieval Europe. There are some beliefs that the Snickerdoodle came to be and orignated in southern Florida, just outside Fort Lauderdale. In Renaissance England, a cookie called a “jumble” was popular in the cuisine. Later, Germans were known to have added more spices and a variety of different dried fruits, eventually evolving into the gingerbread cookie. Cookbooks from the 18th and 19th centuries have also contained recipes comparable to the Snickerdoodle.
 
The origin of the name “Snickerdoodle” has given rise to many theories but few facts. The Joy of Cooking claims that snickerdoodles are probably German in origin, and that the name is a corruption of the German word for “snail dumpling” (Schneckennudeln, or cinnamon-dusted sweet rolls). Similarly, one author states that “the word ‘snicker’ may have come from a Dutch word `snekrad,’ or the German word ‘Schnecke,’ both describing a snail-like shape.” However, another author believes the name came from a New England tradition of fanciful, whimsical cookie names, and yet another cites a series of tall tales around a hero named Snickerdoodle from the early 1900s.   
 
What’s Cooking America
Snickerdoodle Cookies
Cookies as we know them in America were originally brought to the United States by our English, Scottish, and Dutch immigrants. Earlier names for cookies such as Snickerdoodles and Cry Babies originated with the New England states. Even with its early history, cookies did not become popular until about a hundred years ago. In earlier American cookbooks, cookies were given no space of their own but were listed at the end of the cake chapter. They were called by such names as “jumbles,” “Plunkets,” and “Cry Babies.” The names were extremely puzzling and whimsical. New England cooks seem to have had a penchant for giving odd names to their dishes, apparently for no other reason than the fun of saying them. Snickerdoodles comes from a tradition of this sort that includes Graham Jakes, Jolly Boys, Branble, Tangle Breeches, and Kinkawoodles.

“Snickerdoodles” is the somewhat fantastic name of quickly made little cakes especially dear to the children’s heart. A receipt for them copied from an old scrapbook says: “Stir together two cups of sugar and half a cup of butter. When creamy, add two well-beaten eggs, then one cup of milk, with a teaspoonful of soda dissolved in it; and, lastly, and two and a half cups of flour, with two teaspoonfuls of cream of tartar and half a spoonful of salt. Beat the batter thoroughly, and bake in shallow pans, dusting the top of the cake before serving with cinnamon and sugar. Bake fifteen minutes, and when cool cut in squares. This receipt will make two panfuls, which will cut into twenty-four squares.”

In the middle to late nineteenth century regional cookbooks these appear under many names. The earliest church society cookbooks from the Hudson River region call them Schnecken Noodles,
Schneckenoodles, or Snecke Noodles. Lower Midwest cookbooks, especially those of Kentucky and Missouri, list them as Snickerdoodles. Most recipes differ very little from crinkle cookies. Some recipes include 3/4 cup raisins with the sifted flour mixture.

Q. You have often mentioned odd names of curious dishes from Britain and America. How about snickerdoodle?
A. I have tasted a recipe for snickerdoodle that came from Tennessee. Essential it is a short (which is to say rich) cookie that is flavored with cinnamon. I do not know the origin of the name, but it has been proposed that it is of German origin and derived from the word Schnecken, i.e., Schnecken noodles.
