Buttermilk helps to keep the cake super moist, and plenty of cocoa powder makes it taste rich and decadent. Ingredients For the cake layers Vegetable oil, cooking spray 1 ½ cups sugar ¾ cup brown-rice flour ½ cup almond flour ¾ cup unsweetened Dutch-process cocoa powder ¼ cup quinoa flour 2 teaspoons baking soda 1 teaspoon baking powder ¾ teaspoon coarse salt 2 large eggs ¾ cup warm water ¾ cup low-fat (1 percent) buttermilk 1 ounce (2 tablespoons) unsalted butter 1 teaspoon pure vanilla extract For the seven-minute frosting 1 ¼ cups sugar ¼ cup water 1 tablespoon plus 1 teaspoon corn syrup 5 large egg whites ¾ teaspoon pure vanilla extract Pinch of salt Directions Make the cake layers: Preheat oven to 350 degrees. Lightly coat two 8-inch cake pans with cooking spray. Line bottoms with parchment; spray parchment. Whisk together dry ingredients in a large bowl. Add remaining ingredients, and mix until smooth, about 3 minutes. Divide batter between pans. Bake cakes until they pull away from sides of pans, about 1 hour. Let cool in pans on wire racks. Cakes will keep, covered, for up to 1 day. Make the frosting: Place sugar, water, corn syrup, and whites in a heatproof mixer bowl over a pot of simmering water. Cook, whisking occasionally, until sugar dissolves and mixture registers 160 degrees on a candy thermometer. Attach bowl to mixer. Whisk hot sugar mixture on high speed until stiff, glossy peaks form, about 7 minutes. Whisk in vanilla and salt. Assemble the cake: Place a cake layer on a plate. Spread 2 cups frosting on top. Place remaining cake layer on top of frosting. Frost top and sides with remaining frosting. Cake is best eaten within 1 hour of frosting. Cook's Notes We've tinted the finished frosting pink by adding red gel-paste food coloring drop by drop. Feel free to leave it white, or tint it with any favorite color. Rate it Print
