Step 1

Preheat the oven to 350 F.

Step 2

Lightly grease a 9x5-inch pan (1 lb. loaf pan) with some cooking oil or butter.

Step 3

In a large mixing bowl, combine all the dry ingredients including flour, sugar, baking powder, baking soda, cinnamon, and salt. Whisk together until evenly distributed.

Step 4

Add zucchini and walnuts and mix well until evenly combined.

Step 5

In a medium mixing bowl, combine all the wet ingredients including oil, milk, eggs, and vanilla extract. Whisk well until smooth.

Step 6

Pour the wet mixture into the dry ingredients and use a spatula to mix together until just combined and no dry ingredients are visible. Do not overmix the batter.

Step 7

Pour the batter into the prepared loaf pan and smooth out the top with a spatula or the back of a spoon.

Step 8

Bake for 55-60 minutes on the middle rack until golden brown and a toothpick inserted into the center of the cake comes out clean.

Step 9

Let cool for 10-15 minutes, then invert to remove the loaf. Place on a wire cooling rack to cool completely.

Step 10

Slice and serve.
