Best Chocolate Cake

Ingredients
  • 8 ounces (227 grams) bittersweet chocolate, finely chopped
  • 2/3 cup (57 grams) Dutch-process cocoa, sifted
  • 2 teaspoons instant espresso powder*
  • 1 cup boiling water
  • 1 3/4 (222 grams) cups all-purpose flour
  • 1 cup (200 grams) granulated sugar
  • 1/2 cup (100 grams) packed light brown sugar
  • 1 teaspoon salt
  • 1 teaspoon baking soda
  • 1 cup (227 grams) sour cream, at room temperature
  • 1/2 cup vegetable oil*
  • 4 large eggs plus one egg yolk, at room temperature
  • 1 tablespoon white vinegar
  • 2 teaspoons vanilla extract
Directions
  • In a medium heatproof bowl add the chocolate, cocoa powder, and espresso powder. Pour hot water over mixture. Cover and let stand for 5 minutes. Whisk mixture gently until smooth then set aside to cool.
  • Meanwhile, preheat the oven to 350°F. Butter and flour two 8-inch round cake pans.
  • In a small bowl, whisk together the flour, sugars, salt, and baking soda.
  • Whisk sour cream, oil, eggs, egg yolk, vinegar, and vanilla into the cooled chocolate mixture until smooth. Stir in the flour mixture until smooth, being careful not to overmix.
  • Pour the batter into the prepared pans and bake for 35 to 40 minutes, or until a cake tester comes out clean. Cool in the pans for 30 minutes, then carefully turn them out onto a cooling rack to cool completely.
