Fudge Layer Cake

Step 1
Sift together flour, cocoa, baking soda, and salt in a small mixing bowl.

Step 2
In a separate bowl, cream 3/4 cup butter and white and brown sugars at medium speed until light and fluffy. Add eggs, one at a time, beating after each addition. Add 2 teaspoons vanilla. At low speed, begin by adding a little of the flour mixture to the butter mixture. Alternate with buttermilk until all are blended together. Start and end with flour.

Step 3
Line bottoms of 2 9-inch pans with waxed paper; grease and flour. Pour batter in.

Step 5
To Make Frosting: Cream together 3/4 cup butter and confectioners' sugar. Slowly add melted chocolate and 2 teaspoons vanilla. Beat until light and fluffy. Frost cooled cake.
