Sour Cream Spice Cake

Directions

1. 1

   Preheat oven to 350°. In a large bowl, cream butter and brown sugar until light and fluffy. Add egg yolks, one at a time, beating well after each addition. Beat in vanilla. In another bowl, whisk, flour, allspice, baking soda, cinnamon, cloves and salt; add to creamed mixture alternately with sour cream, beating well after each addition. With clean beaters, beat egg whites on medium speed until stiff. Fold into batter.
