- 2 1/4 cups cake flour
- 1 1/2 cups sugar
- 1 cup finely chopped hazelnuts, toasted
- 1 teaspoon baking powder
- 1/2 teaspoon salt
- 5 egg yolks
- 2/3 cup water
- 1/2 cup vegetable oil
- 1 tablespoon vanilla extract
- 8 egg whites
- 1 1/2 teaspoons cream of tartar
- MOCHA FROSTING:
- 3/4 cup butter, softened
- 1 1/2 cups confectioners' sugar
- 2 tablespoons baking cocoa
- 1 teaspoon vanilla extract
- 2 tablespoons hot brewed coffee
- In a large mixing bowl, combine the flour, sugar, hazelnuts, baking powder and salt. Whisk the egg yolks, water, oil and vanilla; add to dry ingredients. Beat until well blended. In another large mixing bowl, beat egg whites and cream of tartar on medium speed until soft peaks form; fold into batter.
- Gently spoon into an ungreased 10-in. tube pan. Cut through the batter with a knife to remove air pockets. Bake on the lowest rack at 325 degrees F for 60-70 minutes or until top springs back when lightly touched. Immediately invert the cake pan onto a wire rack; cool completely. Carefully run a knife around edges and center tube to loosen; remove cake.
