Ingredients
  

Chocolate Zucchini Bread
  • 1.5 cup all-purpose flour
  • 0.5 cup unsweetened cocoa powder
  • 1 tsp baking soda
  • 0.5 tsp baking powder
  • 0.5 tsp salt
  • 1 cup granulated sugar
  • 2 eggs
  • 0.5 cup vegetable oil
  • 0.5 cup sour cream or Greek yogurt
  • 1 tsp vanilla extract
  • 1.5 cup zucchini, grated and squeezed dry
  • 1 cup semi-sweet chocolate chips

Equipment

  • 1 sheet pan
  • 1 stand mixer

Method
 

Prep the oven and pan
  1. Preheat the oven to 350°F and grease a 9x5 loaf pan.
  2. Let the pan sit while you mix the batter.
Mix dry ingredients
  1. Whisk all-purpose flour, unsweetened cocoa powder, baking soda, baking powder, and salt together until evenly combined.
Mix wet ingredients
  1. Beat granulated sugar, eggs, vegetable oil, sour cream (or Greek yogurt), and vanilla extract until smooth.
Combine and add zucchini
  1. Stir in the grated zucchini that has been squeezed dry.
Fold and bake
  1. Fold the dry ingredients into the wet ingredients just until combined, then fold in the semi-sweet chocolate chips.
  2. Pour the batter into the loaf pan.
  3. Bake at 350°F for 55–65 minutes, until a toothpick comes out with a few moist crumbs.
Cool and serve
  1. Cool the loaf for 15 minutes before slicing.
  2. Dust with powdered sugar if desired, then slice to serve.

Notes

Squeeze the zucchini very well to keep the loaf from turning gummy. Store airtight at room temperature for up to 3 days or refrigerate for up to 5 days; freeze slices up to 2 months. For a dairy-light option, use plain unsweetened Greek yogurt-style plant yogurt instead of sour cream.
