Lemon Ginger Cake with Lemon-Cream Cheese Frosting

Position rack in center of oven and preheat to 350 °F. Butter two 9-inch diameter cake pans with 2-inch-high sides. Line bottom of pans with waxed paper; butter paper. Using electric mixer, beat sugar and butter in large bowl until well blended. Add eggs 1 at a time, beating well after each addition. Mix in lemon juice, lemon peel and vanilla (mixture may look curdled). Sift flour, ginger, cinnamon, baking powder, baking soda and salt into medium bowl; add to butter mixture alternately with buttermilk in 3 additions each, beginning with dry ingredients. Divide batter equally between prepared pans. Bake until golden brown and tester inserted into center of cakes comes out clean, about 45 minutes. Transfer pans to racks. Cool 10 minutes. Using small sharp knife, cut around sides of pan to loosen cakes. Turn out cakes onto racks and cool completely. Peel off waxed paper. (Can be prepared 1 day ahead. Wrap tightly in plastic and store at room temperature.)
