CAKE:

Heat oven to 350 degrees. Line two 8-inch (or 9-inch) round cakepans with waxed paper. Lightly grease and flour the waxed paper. Set pans aside.

Stir together the flour, baking soda, salt, and cinnamon.

Beat eggs, sugar, oil, buttermilk, and vanilla at medium speed with an electric mixer until smooth. Add the flour mixture, beating at low speed until blended. Fold in grated carrot, pineapple, coconut, and pecans. Pour batter into prepared cake pans.

Bake at 350 degrees for 25 to 30 minutes or until a wooden pick inserted in the center come out clean. Drizzle Buttermilk Glaze evenly over layers; cool in pans on wire racks for 15 minutes. Remove from pans, and cool completely on wire racks. Spread Cream Cheese Frosting between layers and on the top and sides of cake.
