Ingredients:

  • 1 box (15¼ oz / 432g) spice cake mix
  • 2 cups (240g) zucchini, shredded and squeezed dry
  • 3 large eggs
  • 1/2 cup (120ml) vegetable oil
  • 1/2 cup (120g) sour cream
  • 1 tsp (5ml) vanilla extract
  • 1 tsp (2g) ground cinnamon
  • 1 cup (120g) powdered sugar
  • 2 tbsp (30ml) milk
  • 1/2 tsp (2.5ml) vanilla extract

Instructions:

  1. Preheat the oven to 350°F (180°C). Grease a 9x5 inch loaf pan with butter or line it with parchment paper.
  2. Shred the zucchini using the coarse side of a box grater.
  3. Place the shredded zucchini in a clean kitchen towel or cheesecloth and squeeze firmly over the sink to remove as much liquid as possible.
  4. In a large mixing bowl, whisk together the 3 large eggs, 1/2 cup vegetable oil, 1/2 cup sour cream, and 1 tsp vanilla extract until the mixture is smooth and pale.
  5. Stir in the 432g spice cake mix and 1 tsp ground cinnamon using a rubber spatula until just combined; do not overbeat.
  6. Gently fold in the squeezed shredded zucchini until evenly distributed.
  7. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
  8. Bake for 50 to 60 minutes, until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
  9. Allow the bread to cool in the pan for 10 minutes before transferring it to a wire cooling rack to cool completely.
  10. For the optional glaze, whisk together 1 cup powdered sugar, 2 tbsp milk, and 1/2 tsp vanilla extract until smooth, then drizzle over the cooled loaf.
