Grease a large cookie sheet; set aside. In a large mixing bowl beat butter with an electric mixer on medium to high speed for 30 seconds. Add granulated sugar, brown sugar, cinnamon, baking soda, nutmeg, and cloves. Beat until combined, scraping sides of bowl occasionally. Beat in egg and apple juice until combined. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour, chopped apple, and walnuts with a wooden spoon.

Drop dough by rounded teaspoons 2 inches apart onto prepared cookie sheet. Bake in a 375°F oven for 10 to 12 minutes or until edges are lightly browned. Cool on cookie sheet for 1 minute. Transfer cookies to a wire rack and let cool. Frost with Apple Frosting; let frosting dry.

Apple Frosting: In a large mixing bowl, beat 4 cups sifted powdered sugar, ¼ cup softened butter, 1 teaspoon vanilla, and enough apple juice (3 to 4 tablespoons) with an electric mixer to make a smooth, spreadable frosting.
