1 cake


Chocolate ganache frosting
  • 3 ounces bittersweet chocolate, finely chopped
  • 1/2 cup heavy cream
  • 4 medium beets (1½ pounds), trimmed, peeled, and cut into 2-inch chunks
  • 1/4 cup safflower oil, plus more for pan
  • 1 cup spelt flour
  • 1 cup all-purpose flour
  • cups natural cane sugar
  • 1/2 cup unsweetened Dutch-process cocoa powder
  • teaspoons baking soda
  • 3/4 teaspoon coarse salt
  • 2 large eggs, room temperature
  • 3/4 cup warm water
  • 1 teaspoon vanilla extract

Chef notes

You won't taste the pureed beets, but they make this cake extra moist and fudgy, even with the addition of whole-grain spelt flour. The beets also play up the cake's full-bodied, not-too-sweet flavor.


For the chocolate ganache frosting:

Put chocolate in a bowl. In a small saucepan, heat cream until just simmering. Pour cream over chocolate and let stand 10 minutes; then stir until smooth. Let stand, stirring occasionally, until thickened and spreadable, about 1 hour.

For the cake:

Place beets in a steamer basket set in a saucepan filled with 2 inches of simmering water. Cover and steam until beets are tender when pierced with a sharp knife, about 25 minutes. Let cool slightly, then puree in a food processor until smooth.

Preheat oven to 350°F. Oil one 9-inch square or round cake pan. Line bottom with a parchment.

In a large bowl, whisk together both flours, sugar, cocoa powder, baking soda, and salt. Whisk in eggs, water, oil, vanilla, and 1¼ cups beet puree (reserve remaining puree for another use).

Pour batter into prepared pan. Bake, rotating pan halfway through, until cake is set and a cake tester inserted in center comes out clean, about 35 minutes.

Transfer pan to a wire rack and let cake cool, 20 minutes. Invert cake onto rack and let cool completely.

Place cake on a cake plate and spread evenly with chocolate ganache. (Cake can be kept, covered, up to 2 days.)
