2 1/2 cups flour
2 cups sugar
1-1/2 tsp cinnamon
1 tsp salt
1/2 tsp baking powder
1/2 tsp baking soda
1 cup vegetable oil
4 eggs
2 cups shredded zucchini
1/2 cup chopped walnuts (optional)

Frosting:
4 ounces (1/2 package) cream cheese, softened
1/4 cup (4 tablespoons) butter, softened
1 tbsp milk
1 tsp vanilla extract
2 cups powdered sugar

Heat oven to 350 degrees. Grease a 9-by-13-inch baking pan. Mix flour, sugar, cinnamon, salt, baking powder, and baking soda in a bowl. Mix oil and eggs in another bowl until smooth; add to dry ingredients and mix well. Add zucchini; stir until thoroughly combined. Fold in walnuts, if desired. Spread mixture in prepared pan; bake until a toothpick inserted near the center comes out clean, 35-45 minutes. Cool thoroughly. To make frosting, beat cream cheese, butter, milk, and vanilla until smooth. Add powdered sugar and mix well. Frost cake. Makes 12 or more servings.
