- 2 ounces bittersweet chocolate, melted and cooled
- 1 1/3 cups all purpose flour
- 1/2 cup unsweetened cocoa powder
- 3/4 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
- 1 1/4 sticks (10 tablespoons) butter,at room temperature
- 1/2 cup (packed) light brown sugar
- 1/2 cup granulated sugar
- 3 large eggs, at room temperature
- 1 teaspoon pure vanilla extract
- 1/2 cup buttermilk or whole milk, at room temperature
- 1/2 cup boiling water
- 4 ounces semisweet or milk chocolate, finely chopped,
- or 2/3 cup mini chocolate chips
Filling and Frosting
- 1/2 cup egg whites (about 4 large)
- 1 cup granulated teaspoon cream of tartar
- 1 cup water
- 1 tablespoon pure vanilla extract
Chocolate Drizzle
- 3/4 cup heavy cream, at room temperature
- 1 1/2 cups dark chocolate pieces
- Optional: garnish with round chocolate mint cookies.
Directions
- Preheat oven to 350F.
- Cut parchment paper rounds to fit two 8x2 inch round cake pans. Grease with butter and dust with cocoa powder.
- Place the pans onto a baking sheet.
Cake
- In the top of a double boiler or a small saucepan over low heat, melt the chocolate and set aside.
- In a mixing bowl, sift together the flour, cocoa, baking soda, baking powder and salt.
- In a large mixing bowl, using an electric mixer on medium speed, cream the butter until soft and creamy.
- Beat in the sugar and add the eggs, one at a time, mixing until well combined.
- Beat in the vanilla.
- Reduce the mixer speed to low and mix in the melted chocolate.
- When chocolate is fully incorporated, add the dry ingredients alternately with the buttermilk, adding the dry ingredients in 3 additions and the milk in 2 additions.
- Scrape down the sides of the bowl as needed and mix only until the ingredients disappear into the batter.
- The batter will be thick, like frosting.
- Still working on low speed, mix in the boiling water.
- This will thin the batter considerably.
- Switch to a rubber spatula, scrape down the bowl and stir in the chopped chocolate or chocolate chips.
- Divide the batter evenly into the prepared pans and flatten the tops with the rubber spatula.
- Place into the preheated oven and bake for 25 to 30 minutes, rotating the pans at the midway point.
- Cakes are baked when they are springy to the touch and a toothpick inserted into the centers comes out clean.
- Remove from the oven and place the cake pans on racks to cool for about 5 minutes.
- Run a knife around the sides of the cakes,and turn the cakes out onto the racks.
- Peel off the paper liners.
- Invert and cool to room temperature right side up.
- When you are ready to fill and frost the cake, cut the crowns off the tops to make flat cakes using a long serrated knife with a sawing motion.
- Set the crumbs aside to use later.
- Do not frost until cooled completely.
Filling and Frosting
- You will need a candy thermometer at the ready.
- Put the egg whites into a clean, dry mixing bowl.
- Put the sugar, cream of tartar and water into a medium saucepan and stir to combine.
- Bring the mixture to a boil over medium-high heat.
- Cover with a lid and let boil for 3 minutes.
- Uncover and allow the syrup to boil until it reaches 242F. on the candy thermometer.
- While the syrup is cooking, start beating the egg whites.
- When the syrup reaches 235F., begin beating the egg whites with and electric mixer on medium speed.
- If the whites form firm, shiny peaks before the syrup reaches temperature, reduce the mixer speed to low and keep mixing the whites until the syrup catches up.
- With the mixer at medium speed, carefully pour in the hot syrup, pouring it between the beaters and the side of the bowl.
- Splatters will happen but don't try to scrape them into the whites, just carry on.
- Add the vanilla extract and keep beating the whites for about 5 minutes at medium speed until they reach room temperature.
- You should have a smooth, shiny, marshmallow type frosting.
Chocolate Drizzle
- Place the cream and chocolate in a double boiler over hot but not boiling water. Heat for 3-4 minutes or until chocolate almost melts, stirring occasionally.
- Remove from the heat and use a rubber spatula to stir until all the chocolate melts.
- Let the chocolate cool to room temperature before using.
Assembly
- Put one layer of cake on a cake plate.
- Cover the layer generously with frosting.
- Top with a second layer and cover the entire cake with frosting on the top and sides and use a metal cake spatula to make swirls as you frost.
- Sprinkle the chocolate cake crumbs on, gently pressing the crumbs into the filling with your fingers.
- When you cut and serve the cake, drizzle chocolate on and garnish with a chocolate mint cookie if desired.
- The frosting used in this recipe is best the same day it is made.
