Preheat oven to 350 F degrees.

Spray a 9 x 5 loaf pan with non-stick spray and set aside.

In a bowl whisk together both the flours, baking powder, baking soda, salt, cinnamon powder and nutmeg powder. Set aside.

To another bowl add canola oil, egg and sour cream. Whisk till well combined using your wire whisk.

Add sugar and whisk for 2-3 minutes or till sugar in well mixed with the mixture.

Add vanilla extract to the mix and whisk till well combined.

Now add the flour mix to the wet ingredients. Add the flour in 3 parts, mixing after each addition but be careful not to over-mix.

Fold in the grated zucchini. I manually grated the zucchini using a simple kitchen grater, it took me less than 5 minutes to do it.

Fold in the chocolate chips. This is optional, you can eve add some nuts here.

Transfer batter to the prepared baking pan and bake at 350 F degrees for 50-55 minutes or till a toothpick inserted in the center comes out clean. Mine was done in 55 minutes.

Remove this easy zucchini bread from the oven and let it sit in the pan for around 20 minutes, then run a knife around to pan to release it.

Place the bread on a wire rack to cool completely before cutting into slices.
