07 - 1/4 cup fresh vegetable oil
08 - 1/2 cup (120 grams) full-fat sour cream or plain whole milk yogurt, at room temperature
09 - 2 large eggs plus 1 egg yolk, at room temperature

→ For the icing

13 - 1/2 cup (63 grams) powdered sugar, sifted
14 - 1 tablespoon milk

# Instructions:

01 - Preheat the oven to 350°F. Line an 8 by 8-inch metal baking pan with parchment paper and spray with nonstick cooking spray.
02 - In a large bowl, whisk together the flour, cocoa, sugar, salt, and baking soda.
03 - In a small bowl, whisk together the melted butter, oil, sour cream, eggs, egg yolk, and vanilla extract.
04 - Make a well in the center of the dry ingredients. Pour in the wet ingredients and stir until a few streaks of flour remain. Add the squeezed shredded zucchini and chocolate chips, stirring until just combined.
05 - Pour the batter into the prepared pan and bake for 30 minutes or until a toothpick inserted into the center comes out clean. Let the cake cool completely.
06 - In a medium bowl, stir together the powdered sugar and milk with a fork until smooth and thick but pourable. Drizzle evenly over the cooled cake and let set before serving.

# Notes:

01 - If baking in a glass pan, reduce the oven temperature to 325°F and increase bake time to 35-40 minutes.
