From The Joy of Cooking
7.5 oz (1.5 cups) flour
1 tsp baking powder
1 tsp baking soda
1/4 tsp cinnamon
2/3 cup sugar
1/2 cup canola oil
1 tsp vanilla
1/2 tsp salt
8 oz (~2 cup) grated zucchini
1.5 cups chopped toasted walnuts (optional)
Heat oven to 350F
Combine flour, baking powder, baking soda, and cinnamon in a large bowl. Whisk well to combine.
Combine sugar, eggs, vanilla, and salt in a food processor. With the food processor running, add the oil.
Transfer the sugar mixture to a medium bowl and stir in the zucchini and nuts.
Fold the zucchini mixture into the flour.
Makes a single 9×5 loaf (45 minutes), about a dozen muffins (25 minutes), or about four dozen mini-muffins (15 minutes).
Our household is split on the nuts issue so I scoop out half the muffins, then add nuts, then scoop the rest.
