Preheat oven to 350 degree. Grease two regular bread pans or four miniature bread pans.
Whisk together the flours, sugar, spices, salt, and baking soda.
Make a well in dry ingredients and add the squash puree, oil, eggs, and water. Stir to combine.
Divide the batter between the prepared loaf pans and bake for 50 to 65 minutes. They're done when a toothpick or cake tester comes out clean.
