Preparation Center an oven rack and preheat the oven to 350°F. Put the unsweetened chocolate and the cocoa into a small bowl. Pour the boiling water over the chocolate and allow it to steep for 1 minute. Whisk the mixture together. Whisk in the sour cream and vanilla. Set aside. Sift together the flour, baking soda, and salt in a bowl, then whisk the mixture by hand to ensure that the ingredients are well mixed. In the bowl of a stand mixer fitted with the paddle attachment, cream the butter and both sugars together on medium-high speed until light, about 3 minutes. As you make the batter, stop the mixer frequently and scrape the paddle and the sides of the bowl with a rubber spatula. On low speed, drizzle the oil into the mixture until blended. Turn the mixer up to medium-high speed and beat until the batter is fluffy, about 3 more minutes. Blend in the eggs and egg yolks one at a time, adding the next one as soon as the previous one has disappeared into the batter. With the mixer on low speed, add the flour mixture in three parts, alternating with the chocolate mixture in two parts, beginning and ending with the flour. After each addition, mix until just barely blended and stop and scrape the bowl. Stop the mixer before the last of the flour has been incorporated and complete the blending by hand with a rubber spatula to ensure you do not overbeat the batter. Divide the thick batter equally among the prepared pans (there will be approximately 1 pound 2 ounces per pan). Smooth the tops and tap the pans on the counter to settle the batter and eliminate any large air bubbles. Bake in the middle of the oven until the centers spring back when lightly touched, 22 to 25 minutes. Cool the cakes in their pans on a wire rack for 30 minutes. Flip the cakes out of the pans, leaving on the parchment paper until you assemble the cake. Let them continue to cool on the rack, top sides up, until they reach room temperature. To assemble the cake, lay one of the cakes top side up on a cake plate. Using a metal spatula, frost the top with 3/4 cup of buttercream, spreading it out to the edge of the cake (the filling will be about 1/4 inch thick). Stack the second cake top side up on top of the frosted cake and spread another 3/4 cup of buttercream on top of it. Stack the last layer of cake top side up on top. Look for any frosting that may have oozed out beween the layers and spread it along the sides of the cake. Apply a thin layer of frosting all over the cake to create a "crumb coat." Place the cake in the refrigerator until the frosting is firm, about 10 minutes. Take it out and frost the cake with the remaining buttercream, using your spatula to make decorative swirls. Store the cake in an airtight container at room temperature for up to 3 days. Sugar Syrup to the RescueAt Baker & Spice Bakery, before frosting a cake we coat the layers with sugar syrup, which helps to keep the cake moist and adds flavor at the same time. This trick will also help to salvage a dry cake. To make a sugar syrup, combine 1/2 cup boiling water, 1/4 cup sugar, and 1 teaspoon pure vanilla extract or other flavoring (such as Kahlua or Grand Marnier) and stir until dissolved. Let the syrup cool, then brush a coat of it onto the top of each cake layer before you frost it.
