Chocolate Fudge Cake
3 1/2 cups flour
1 cup sugar
1/2 cup light-brown sugar, packed
1/2 cup unsweetened cocoa powder
2 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
3 large eggs
1/2 cup sour cream
1 tablespoon vanilla
6 tablespoons unsalted butter, melted and cooled
1/2 cup corn oil
1 1/2 cups cold water
6 ounces bittersweet chocolate, chopped
1/2 cup unsalted butter, room temperature
1 1/2 cups confectioners sugar, sifted
2 teaspoons vanilla
Heat oven to 350 degrees. Butter bottom of two 8x2" round baking pans. Line bottoms with waxed paper or parchment paper rounds. Butter paper.
In large bowl, stir together the flour, sugar, brown sugar, cocoa powder, baking powder, baking soda and salt until well blended.
In medium bowl, whisk together eggs, sour cream and vanilla until blended.
In another large bowl, beat together the melted butter, corn oil and cold water until blended. On low speed, add the flour mixture all at once; then beat in the egg mixture. Continue to beat until the mixture is smooth. Evenly divide the batter between the pans, spreading the batter to edge of pan.
Bake the cakes in 350 degree oven for 50-55 minutes or until a toothpick inserted in the top centers of the cakes comes out clean. Let the cakes cool in the pans on a wire rack for 15 minutes. Invert cakes onto racks; remove the pans and waxed paper. Let the cakes cool completely.
FUDGE ICING: Place the chopped chocolate in a small microwave safe bowl. Microwave on 50% powder until the chocolate is melted, 2-3 minutes; let cool slightly. In medium bowl, beat the butter until creamy. Beat in confectioners' sugar until light and fluffy. Beat in melted chocolate and vanilla until the mixture is smooth.
To assemble: With a serrated knife, trim the top of one cake layer to make it level. Place the layer, trimmed side up on a serving plate. Spread theh top with about 1/2 cup of the icing. Place the second cake layer, rounded side up, on top of the first. Rusing a metal frosting spatula and the remaining icing, spread the icing evenly over the side of the cake. Then spread icing evenly over the top.
