chocolate zucchini bread

This bread has a whole lot going on but when I discovered it on not one but http://asweetspoonful.com/ blogs I thought I should try it. Since making it, the girl asks at least once a day for "chocolate bread please". I made bran muffins this morning hoping she'll think they are similar...we'll see. This recipe is copied exactly from Seven Spoons, copy and paste. The only change I made was using half the amount of chocolate (4 ounces) and swapping the walnuts for pecans. I would really like to try this recipe without the cocoa powder, maybe it would taste more like this? I love that one but if you have an abundant amount of zucchini, as many people do, I think this is a great option for using up all those squash.

Chocolate Olive Oil Zucchini Bread
via Seven Spoons
Ingredients
Softened butter, for pans
1 1/2 cups whole wheat flour
1 1/2 cups all-purpose flour
1/2 cup cocoa powder
1 teaspoon baking powder
1 teaspoon baking soda
1 1/2 teaspoons salt
1 cup chopped walnuts, toasted (I used pecans)
8 ounces semisweet chocolate, chopped
1/2 cup olive oil
1 cup well-shaken buttermilk
2 eggs
1 1/2 cups fine-grained turbinado sugar
2 teaspoons vanilla extract
4 cups shredded zucchini, see note

Preheat an oven to 350°F (175°C). Grease two 9-by-5-by-3-inch loaf pans with softened butter. Use a length of parchment to line the bottom and long sides of the pan, forming a sling, and lightly butter the parchment as well. Set aside.

In a large bowl, whisk together the flours, cocoa powder, baking powder, baking soda and salt. Stir in the chopped walnuts and chocolate. Set aside.

In another bowl, whisk together the olive oil and buttermilk. Add the eggs, sugar and vanilla, and beat until smooth. Stir in the zucchini.

Pour the wet ingredients into the dry, stir until combined, taking care not over mix. Divide the batter evenly between the two prepared pans and bake, rotating once, until a cake tester inserted into the loaf comes out almost clean, which should be around 50 minutes. Cool loaves in their pans on a rack for 20 minutes, then grasp the edges of the parchment to ease the bread out.

Makes 2 loaves.

Notes:
For the zucchini, I use the grating attachment on my food processor, taking care not to press down on the feed tube plunger while the machine is running - this gives a light, feathery shredding. Since we want a bread that is damp but not sodden, I sprinkle the emerald-tipped strands across a (lint-free) kitchen towel, then place another atop, patting it down gently. After a few minutes the towels will have absorbed some of the excess liquid and the zucchini is left crisp and ready to go.
