Chocolate Zucchini Loaf Cake

Chocolate Zucchini Loaf Cake

This simple, one-bowl loaf cake is a sweet way to make the most of zucchini season. Chocolate cake batter is flecked with shreds of raw zucchini and studded with bittersweet chocolate chips for a summertime cake that’s fit for either breakfast or dessert. While some recipes call for squeezing the excess water out of the shredded zucchini, this loaf cake takes full advantage of the summer vegetable: The zucchini is taken directly from the grater to the bowl for additional moisture. The resulting cake strikes the perfect balance; it's rich and fudgy, but still maintains a tender crumb. The cake will keep on the counter for 4 to 5 days, loosely covered, and only gets better with age.

Yield: 1 loaf (about 8 servings)

Nonstick cooking spray or neutral oil

2 large eggs

1½ cups/330 grams packed light brown sugar

¾ cup/180 milliliters neutral oil (such as vegetable or safflower)

2 teaspoons vanilla extract

1 teaspoon kosher salt (such as Diamond Crystal)

2 cups/280 grams lightly packed coarsely grated zucchini (from about 1 large or 2 small zucchini)

1¾ cups/223 grams all-purpose flour

⅔ cup/63 grams unsweetened natural cocoa powder

1 teaspoon baking powder

1 teaspoon baking soda

1 cup/173 grams bittersweet or semisweet chocolate chips

1 tablespoon coarse sugar (such as turbinado or Demerara)

Heat oven to 325 degrees. Grease a 9-by-5-inch loaf pan with nonstick cooking spray and line with a strip of parchment paper that hangs over the long sides to create a sling.

In a large bowl, vigorously whisk together the eggs, light brown sugar, oil, vanilla extract and salt until smooth and glossy, about 30 seconds. Add the grated zucchini and mix with a rubber spatula until incorporated.

Using a fine-mesh strainer, sift the flour, cocoa powder, baking powder and baking soda directly into the bowl and stir with a rubber spatula just until combined and no pockets of unincorporated flour remain. (Try not to overmix.) Add all but 1 tablespoon of the chocolate chips to the batter and stir until evenly distributed.

Transfer the batter to the prepared pan. Sprinkle the top with coarse sugar and the reserved chocolate chips, pressing them in slightly so they stick. Bake until the cake puffs slightly and a skewer or cake tester inserted into the center comes out clean with just a few moist crumbs attached or with smudges of melted chocolate chips (the chips will be dark brown versus the lighter color of uncooked cake batter), 75 to 80 minutes.

Let the loaf cake cool in the pan for 15 minutes. Using the parchment paper, lift the cake out of the pan and let cool completely on a rack before slicing, about 2 hours.

Tip: The cake can be baked in a 9-by-2-inch round cake or springform pan. Grease the pan and line the bottom with a parchment paper round. Bake until a cake tester inserted into the center comes out clean with just a few moist crumbs attached, 50 to 55 minutes.

Last week I asked about substituting fat-free Greek yogurt for some of the oil. I figured it out and it was perfect - instead of 6oz of oil I used 2oz oil and 3oz of yogurt. Delicious, and eliminated 2/3 of the oil. Super moist and chocolatey.

I have tried many zucchini breads and cakes, but was always bothered by their oiliness. I have now made this one twice substituting the 3/4 cup oil with 1/2 cup buttermilk and 1/4 cup either oil or melted butter or combination of the two ( to equal 1/4 cup). Found that hint on the King Arthur baking site. It really works well.

Perfect in a 9 inch round cake pan, baked 60 minutes. Moist and so delicious. The only change I made was the addition of a sprinkling of chopped pecans on the top along with the coarse brown sugar and chocolate chips. This cake will have thousands of 5 star reviews very shortly!

So very good! I also like that the zucchini doesn’t have to be drained. I used bittersweet chunky chips and I made these as muffins. It made 15 regular muffins and I baked them at 350 for 30 minutes.

Tasty recipe, I reduced the sugar to 1 cup and it was very nice and chocolaty but I would follow what others said and add nuts, coconut, and/or warm spices (cardamon, nutmeg, allspice) for more texture and dimension. The zucchini adds moisture and some texture but mostly disappears into the bread.
