Chocolate Cake Recipe Moist

Prepare cake layers: Preheat oven to 350°F. Grease three 8-in. round cake pans. Line bottoms with waxed paper; grease paper. Dust pans with flour

On another sheet of waxed paper, combine flour, cocoa, baking soda, and salt. In large bowl, with mixer at low speed, beat butter and brown and granulated sugars until blended. Increase speed to high; beat 5 minutes or until pale and fluffy, occasionally scraping bowl with rubber spatula.

Reduce speed to medium-low; add eggs, 1 at a time, beating well after each addition. Beat in vanilla until blended. Add flour mixture alternately with buttermilk, beginning and ending with flour mixture; beat just until batter is smooth, occasionally scraping bowl with rubber spatula.

Spoon batter evenly among prepared pans. If necessary, stagger pans on 2 oven racks, placing 2 on upper rack and 1 on lower rack, so that top pans are not directly above bottom one.

Bake 22 to 25 minutes or until toothpick inserted in center of cake comes out clean. Cool in pans on wire racks 10 minutes. With small knife, loosen layers from sides of pans; invert onto wire racks. Carefully remove and discard waxed paper; cool completely, about 45 minutes. Bring to room temperature before frosting cake.

In small bowl, combine cocoa and boiling water, stirring until smooth. In large bowl, with mixer at medium-high speed, beat butter and confectioners' sugar 5 minutes or until fluffy.

Reduce speed to medium-low; add melted chocolate, then cocoa mixture, beating until smooth and occasionally scraping bowl with rubber spatula. If frosting is too runny, refrigerate until just stiff enough to spread.

Assemble cake: Place 1 cake layer bottom side up on cake plate; spread with 1/3 cup frosting. Top with second layer, bottom side up; spread with 1/3 cup frosting. Place remaining layer bottom side up on top. Spread remaining frosting over sides and top of cake.
