Carrot Cake

Sweetening cakes and puddings with carrot is an old European practice, used heavily in Britain during the Second World War when sugar was rationed and carrots were plentiful. The cake became a fixture of American baking in the 1960s and especially the 1970s, when it fit the era's enthusiasm for 'natural' and wholesome ingredients and appeared widely in restaurants and on packaged-mix boxes; the now-standard cream-cheese frosting was popularized in this American period. The exact path by which carrot cake reached its modern American form is not pinned to a single creator and the wartime-to-1970s narrative is the best-supported general account.

The crumb is dense, moist, and a little chewy, flecked with soft shreds of carrot and the crunch of walnuts. It is sweet and warmly spiced, the cinnamon clear, with a faint earthy-sweet carrot background rather than a vegetable taste. The cream-cheese frosting is cool, thick, and pleasantly sour, cutting the oil-rich cake. There is often a chew from raisins and a brightness if pineapple was added. Each forkful balances richness against the frosting's tang.

Carrot cake is an oil-based, chemically leavened batter rather than a creamed-butter one: oil stays liquid at room temperature so the crumb reads moist, and grated carrot adds water and sugar that further keep it damp. Baking soda and baking powder release carbon dioxide to lift the heavy batter, and the soda's alkalinity also encourages browning. Because there is no whipped-butter foam, mixing can be quick and the structure comes from egg and gluten. The frosting is an emulsion of cream cheese, butter, and sugar; the cream cheese's acidity and water content make it softer and tangier than a plain buttercream, so it must stay cool to hold its shape.
