We are on the brink of zucchini season, but I could not wait to get a running start with a new take on zucchini bread.

I love zucchini bread. My mother grew zucchini every summer and made many whole wheat loaves to use up her annual bounty. Her healthy, wholesome baking spoiled me, to the point where I do not enjoy traditional zucchini bread, specifically the versions that are loaded with sugar, and white flour, yet very little zucchini.

So I came up with a recipe that pleases me, will make my mom proud, and (I predict) will make you jump for joy when you try it. It’s my Zucchini Oat Bread, made with rolled oats and coconut flour.

How to Make Oat & Coconut Flour Zucchini Bread

(1) Blend the Zucchini 

Rather than grating the zucchini, you’ll make what is essentially a zucchini smoothie. Trim the ends off of the zucchini, cut into large pieces, and then process, along with 1 cup of nondairy milk, until smooth.

This zucchini puree provides ample moisture to the bread as well as even distribution (to the extreme!) of the zucchini.

(2) Mix the Remaining Ingredients in a Bowl

Transfer the zucchini puree to a large bowl and add the remaining ingredients: coconut flour, coconut sugar (only 1/3 cup for the entire loaf), flaxseed meal, vanilla, cinnamon, baking soda, and salt.

The flaxseed meal, along with the zucchini puree and flaxseed, eliminate the need for oil in the bread.

The addition of coconut flour requires explanation. I originally experimented with an all-oat loaf. My attempts were both flat and gummy, but still tasty, so I knew I was on track.  Coconut flour, along with some proportion retooling, changed everything, resulting in a decidedly BREAD-y loaf. Hurrah!

Give everything a good stir and the batter is done!

I know what some of you are thinking: why not add all of the ingredients to the blender and save dirtying a bowl? I had the same thought, and I tried it. While not terrible, keeping the oats whole results in a far superior, toothsome texture.

Also, the bottom of the completely pureed loaf was markedly denser than the top portion. No thanks. Cleaning the blender was no fun, either (by comparison, the zucchini milk “smoothie” rinses out with ease).

(3) Spread & Bake the Batter

Spread the batter evenly in a 9×5 inch (22.5 x 12.5cm) loaf pan that has been sprayed or greased, smoothing the top.

Then it’s off to bake in a preheated 375F (190C) preheated oven.

In 45 to 50 minutes, this is the golden-brown result:

(4) Cool & Slice

Transfer the pan to a wire rack to cool completely. Once cooled, run a knife around the edges of the pan to release the loaf.

This bread is hearty, wholesome and delicious! You can stir in your favorite kinds of bits and pieces (e.g., dried fruit, chopped nuts or seeds, shredded coconut, dark chocolate chips) or slather slices with nut butter and jam for instant breakfasts and snacks on the run.

Eating lots of vegetables is a breeze with recipes such as this. Happy baking, everyone!
