Let's Cook
-
Step 1.
Preheat oven to 350°F. In a large bowl, cream together ⅔ cup butter and 2 cups granulated sugar until light and fluffy. Add 2 eggs one at a time, beating well after each addition.
-
Step 2.
Gradually add 2 cups flour and 1⅓ cups buttermilk in alternating additions, starting and ending with flour, mixing just until combined. In a small bowl, dissolve 1⅓ teaspoons baking soda in ⅖ cup hot water, then stir into batter. Add 3½ squares melted bitter chocolate and 1 teaspoon vanilla extract, mixing until smooth.
-
Step 3.
Pour batter into a greased 9-by-12-inch pan or two greased 9-inch round springform pans. Bake for 30 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool completely in the pan on a wire rack.
-
Step 4.
While the cake cools, combine all frosting ingredients (½ cup butter, 3 squares bitter chocolate, 2 cups granulated sugar, ¾ cup milk, 1 teaspoon vanilla extract, 1 teaspoon almond extract) in a saucepan. Bring to a full boil over medium heat, stirring constantly, then boil for exactly 2 minutes. Remove from heat and let cool until thickened; you can place the saucepan on ice to speed cooling.
-
Step 5.
Once the cake is completely cool, remove it from the pan. Spread the cooled frosting evenly over the top and sides. Slice and serve.
