Preparation
Place grapefruit and orange slices on a greased and foil-lined baking sheet. Sprinkle with sugar. Bake at 170° for about 2 hours or until dried (fruit will be slightly tacky). Remove to wire racks. Let stand for 2-3 days or until completely dried.
In a large bowl, cream butter and sugar until light and fluffy, about 5 minutes. Add eggs, one at a time, beating well after each addition. Stir in vanilla and lemon zest; mix well. Combine the flour, baking powder, salt and baking soda; add to creamed mixture alternately with milk and grapefruit juice. Beat just until combined.
Transfer to two greased and floured 9-in. round baking pans. Bake at 350° for 21-24 minutes or until a toothpick inserted in the center comes out clean. Cool for 10 minutes before removing to wire racks to cool completely.
In a large bowl, beat cream cheese and butter until fluffy. Add the confectioners’ sugar, citrus zests and vanilla; beat until smooth.
Cut each cake horizontally into two layers. Spread frosting between layers and over top and sides of cake. Garnish with citrus slices.
