Ingredients

1 1/2 cups buttermilk
1 tablespoon instant coffee
1 tablespoon vanilla extract
675 grams sugar
290 grams all-purpose flour, plus extra for dusting pans
150 grams cocoa powder, sifted
13 grams baking powder
13 grams baking soda
1 teaspoon table salt
1 1/2 sticks unsalted butter, melted and cooled slightly
5 eggs
2 1/4 cups sugar
9 large egg whites
5 sticks unsalted butter, softened
1 tablespoon pure vanilla extract
800 grams Swiss meringue buttercream
3/4 cup raspberry puree

Steps:

For the cake: Preheat the oven to 350 degrees F. Grease two 9-by-2-inch round cake pans; dust the pans with flour, and knock out excess.
In a large measuring cup, combine the buttermilk, coffee, vanilla and 1 1/2 cups water. In a stand mixer fitted with the paddle attachment, add the sugar, flour, cocoa powder, baking powder, baking soda and salt. Mix on low speed. Mix in the butter and eggs, and then slowly add the buttermilk mixture, scraping down the sides of the bowl as needed.
Divide the batter evenly between the prepared cake pans. Bake until the cake layers begin to pull away from sides of the pan and a toothpick inserted into center comes out clean, 22 to 25 minutes.
For the Swiss meringue buttercream: Add the sugar and egg whites to a heatproof stand mixer bowl, and set over a pan of simmering water. Whisking constantly, heat until the sugar is dissolved and the mixture registers 160 degrees F on an instant-read thermometer. Transfer the bowl to the stand mixer fitted with the whisk attachment, and beat on medium-high speed until fluffy and cooled, about 10 minutes. Continue beating until stiff, glossy peaks form. Reduce the speed to medium-low and add the butter, 1 tablespoon at a time, beating well after each addition. Add the vanilla. (Makes 7 cups. See Cook's Note.)
For the raspberry buttercream: In a stand mixer fitted with paddle attachment, beat 800 grams of the Swiss meringue buttercream together with the raspberry puree until fully incorporated. (Makes 4 cups.)
To assemble: Level and tort both cakes--you will end up with 4 layers of cake. Place one cake layer on a serving platter; add about a 1/2-inch layer of the raspberry buttercream. Repeat until you have 4 stacked layers of cake and 3 layers of filling. Frost the cake with the remaining Swiss meringue buttercream.
