California Date Nut Cake: The Coachella Valley Dessert Born of the Desert Date Groves

The Coachella Valley, a sun-baked stretch of the Southern California desert east of Los Angeles, produces ninety-five percent of the dates grown in the United States. The desert date industry began in 1904, when the United States Department of Agriculture established an experimental date station near the town of Mecca, and by the 1920s, date shoots brought from Morocco, Iraq, and Egypt had taken root and flourished in the valley's intense heat and abundant irrigation water. The Medjool and Deglet Noor dates that the valley produces became the foundation of a distinctive California desert cuisine, and the date nut cake, a moist, dark, caramel-sweet loaf studded with chopped dates and walnuts, is its most enduring dessert, served at roadside date stands and farm kitchens from Indio to Palm Springs for the better part of a century (California Dates — Welcome to Coachella Valley; Civil Eats — The History of Coachella's Iconic Dates).

The date nut cake is a humble dessert, born of the desert's pantry: dates, walnuts, and flour, with buttermilk to soften the crumb and brown sugar to deepen the caramel notes of the dates. The dates are soaked in hot water to soften and plump, then folded into a batter that bakes into a dense, moist, almost pudding-like cake, finished with a brown-sugar-butter sauce or a simple dusting of powdered sugar. The cake is the cousin of the date shake, the Palm Springs roadside signature of dates blended with ice cream that originated in the 1930s, and the two together are the taste of the California desert.

Ingredients (serves 6): - 1 cup Medjool or Deglet Noor dates, pitted and chopped - 1 teaspoon baking soda - 1 cup boiling water - ½ cup (1 stick) unsalted butter, softened - 1 cup packed brown sugar - 2 large eggs - 1 teaspoon vanilla extract - 2 cups all-purpose flour - ½ teaspoon salt - 1 teaspoon baking powder - 1 cup chopped walnuts - For the sauce (optional): ½ cup brown sugar, ¼ cup (½ stick) butter, ¼ cup heavy cream, 1 teaspoon vanilla

Instructions: Place the chopped dates in a bowl, sprinkle with the baking soda, and pour the boiling water over them; let stand 20 minutes to soften. Preheat the oven to 350°F and grease a 9-by-5-inch loaf pan or an 8-inch square pan. In a bowl, cream the butter and brown sugar until fluffy. Beat in the eggs, one at a time, then the vanilla. In another bowl, whisk the flour, salt, and baking powder. Add the dry ingredients to the butter mixture in three additions, alternating with the date mixture (with its liquid), beginning and ending with the dry. Fold in the walnuts. Pour into the pan and bake 45 to 55 minutes, until a toothpick comes out clean. For the sauce: in a saucepan, melt the brown sugar, butter, and cream together; simmer 3 minutes and stir in the vanilla. Serve the cake warm with the sauce poured over.

For a Crowd (serves 12): - Bake in a 9-by-13 pan (increase the bake time to 35 to 40 minutes) and serve cut into squares, sauced, with a scoop of vanilla ice cream. The cake keeps well, wrapped, for several days and is moister on the second day.

Variations: - Coachella Valley Classic: The date and walnut loaf with a brown-sugar-butter sauce, as above. - Date Nut Bundt: Bake the batter in a Bundt pan and glaze with a date-caramel drizzle for a celebration version. - Date and Pecan: Substitute pecans for the walnuts and add a teaspoon of cinnamon for a spiced, Southern-californian take.

Pairing: A date nut cake pairs with a cup of strong coffee, a glass of cold milk, or a glass of dessert sherry. For a brunch gathering, a sparkling mimosa or a sweet Muscat complements the caramel notes of the dates. Serve warm, with the sauce and, if you like, a scoop of vanilla ice cream.

Pro Tips: Use Medjool dates if you can find them; they are softer, sweeter, and more caramel-like than the Deglet Noor, and they make a better cake. The boiling-water-and-baking-soda soak is essential; it softens the dates and breaks them down so they melt into the batter, rather than staying as chewy lumps. Do not drain the soaking liquid; it carries the flavor and the sugar into the cake. Toast the walnuts briefly in a dry pan before chopping, for a deeper, less bitter flavor. The cake is better the day after it is baked, because the date flavor deepens and the crumb softens; serve it warm, with the sauce, and it becomes the taste of the California desert.
