|Main ingredients||Chocolate or cocoa powder|
Chocolate cake or chocolate gâteau (from French: gâteau au chocolat) is a cake flavored with melted chocolate, cocoa powder, or both.
Chocolate cake is made with chocolate. It can also include other ingredients. These include fudge, vanilla creme, and other sweeteners. The history of chocolate cake goes back to the 17th century, when cocoa powder from the Americas was added to traditional cake recipes. In 1828, Coenraad van Houten of the Netherlands developed a mechanical extraction method for extracting the fat from cacao liquor resulting in cacao butter and the partly defatted cacao, a compacted mass of solids that could be sold as it was "rock cacao" or ground into powder. The processes transformed chocolate from an exclusive luxury to an inexpensive daily snack. A process for making silkier and smoother chocolate called conching was developed in 1879 by Rodolphe Lindt and made it easier to bake with chocolate, as it amalgamates smoothly and completely with cake batters. Until 1890 to 1900, chocolate recipes were mostly for chocolate drinks, and its presence in cakes was only in fillings and glazes. In 1886, American cooks began adding chocolate to the cake batter, to make the first chocolate cakes in the US.
The Duff Company of Pittsburgh, a molasses manufacturer, introduced Devil's food chocolate cake mixes in the mid-1930s, but introduction was put on hold during World War II. Duncan Hines introduced a "Three Star Special" (so called because a white, yellow or chocolate cake could be made from the same mix) was introduced three years after cake mixes from General Mills and Duncan Hines, and took over 48 percent of the market.
In the U.S., "chocolate decadence" cakes were popular in the 1980s; in the 1990s, single-serving molten chocolate cakes with liquid chocolate centers and infused chocolates with exotic flavors such as tea, curry, red pepper, passion fruit, and champagne were popular. Chocolate lounges and artisanal chocolate makers were popular in the 2000s. Rich, flourless, all-but-flourless chocolate cakes are "now standard in the modern pâtisserie," according to The New Taste of Chocolate in 2001.
