Preheat your oven to 350 degrees Fahrenheit. Spray a 9" loaf pan with nonstick cooking spray. Pour hot or boiling water over the raisins, if using, and allow them to soak for at least 5 minutes, then strain.
In a large bowl, mix together the dry ingredients.
1 ¾ cups (234 grams) all-purpose flour, 1 cup (200 grams) granulated sugar, ½ teaspoon baking powder, ¾ teaspoon baking soda, ½ teaspoon salt, 1 ¾ teaspoons ground cinnamon, 3 Tablespoons vanilla instant pudding mix
In another bowl, whisk together the wet ingredients.
2 eggs eggs, ½ cup vegetable oil, 1 teaspoon vanilla extract, 1 cup grated zucchini, ½ cup buttermilk
Add the wet ingredients to the dry mixture and stir until just combined.
Stir in the nuts and strained raisins (if using) and mix well.
½ cup chopped nuts, ½ cup raisins
Pour the batter into a greased loaf pan. Bake the bread for 50-60 minutes, or until a toothpick inserted into the center comes out clean.
Let the bread cool in the pan for 10 minutes before removing it to a wire rack to cool completely. Enjoy!
