Preheat the oven to 300 degrees. Grease a 9-inch by 13-inch cake pan. Cream the sugar, and egg. Add the oil. Add all dry ingredients into the sugar and egg mixture. Beat well. Add Zucchini, coconut, and nuts. Mix until thoroughly combined. Spread evenly into the cake pan. Bake at 300 degrees for 1 hour to 1-1/2 hours. June's recipe said to bake one hour. I live in Southern Utah and one hour was not enough. Please use the toothpick test. If the toothpick comes out clean, it's done. Ice while hot with a cream cheese icing.
MY CREAM CHEESE FROSTING: 4-ounces cream cheese softened, 1/4 cup butter, softened, 1-1/2 cups powdered sugar and 1/2 teaspoon vanilla. Combine ingredients in a medium-size-bowl and use a hand mixer to blend until smooth.
