Ingredients:
- 1 cup (227g) unsalted butter, softened
- 2 cups (400g) granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract (5ml)
- 4 ounces (113g) unsweetened chocolate, melted and cooled
- 2 cups (250g) all-purpose flour
- 1 teaspoon baking soda (5ml)
- 1/2 teaspoon salt (2.5ml)
- 1 cup (240ml) buttermilk
- 1 cup (227g) unsalted butter, softened
- 6 ounces (170g) cream cheese, softened
- 6 cups (720g) powdered sugar, sifted
- 1 teaspoon vanilla extract (5ml)
- 1/2 cup (120ml) sour cream
- 1 cup chopped pecans or walnuts, for garnish (optional)
Instructions:
- Preheat oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, line the bottoms with parchment paper circles.
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Beat in the eggs one at a time, then stir in the vanilla extract.
- Melt the unsweetened chocolate according to package directions (microwave or double boiler). Let cool slightly.
- Gradually add the melted (and cooled) chocolate to the butter mixture, mixing until combined.
- In a separate bowl, whisk together the flour, baking soda, and salt.
- Gradually add the dry ingredients to the wet ingredients, alternating with the buttermilk, beginning and ending with the dry ingredients. Mix until just combined. Do not overmix.
- Pour the batter evenly into the prepared cake pans. Bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes before inverting them onto a wire rack to cool completely.
- In a large bowl, cream together the softened butter and cream cheese until light and fluffy.
- Gradually beat in the powdered sugar, then stir in the vanilla extract.
- Stir in the sour cream until smooth and creamy.
- Once the cakes are completely cool, place one layer on a serving plate. Spread with a generous layer of frosting. Top with the second cake layer and frost the entire cake.
- Sprinkle the top of the cake with chopped pecans or walnuts.
- For best results, chill the cake for at least 30 minutes before serving.
