Made a double batch to bring some into work - it was a big hit! I went the safe route since I was doing a double batch and used the highest rated zucchini bread recipe from allrecipes :) - except I eliminated the walnuts. I used summer squash as well.
3 cups all-purpose flour
1 teaspoon salt
1 teaspoon baking soda
1 teaspoon baking powder
3 teaspoons ground cinnamon
1 cup vegetable oil
2 1/4 cups white sugar
3 teaspoons vanilla extract
2 cups grated zucchini (drained)
Grease two 8 x 4 inch pans. Preheat oven to 325 degrees F
Mix flour, salt, baking powder, soda, and cinnamon together in a bowl.
Beat eggs, oil, vanilla, and sugar together in a separate large bowl. Add dry ingredients to the creamed mixture, and beat well. Stir in zucchini until well combined. Pour batter into prepared pans.
