Ingredients

Scale

Dry Ingredients

1 cup plus 2 tablespoons (143 grams) all-purpose flour
1/2 cup (43 grams) unsweetened cocoa, measured correctly
1 cup (200 grams) light brown sugar
1 teaspoon fine sea salt
1 teaspoon baking soda

Wet Ingredients

4 tablespoons (57 grams) unsalted butter, melted
1/4 cup fresh vegetable oil
1/2 cup (120 grams) full fat sour cream or plain whole milk yogurt, at room temperature
2 large eggs plus 1 egg yolk, at room temperature
2 teaspoons vanilla extract
1 cup (136 grams) shredded zucchini, from about 1 medium zucchini (excess moisture squeezed out)

Add-ins and Topping

1 cup (170 grams) semisweet chocolate chips
1/2 cup (63 grams) powdered sugar, sifted
1 tablespoon milk

Instructions

Preheat the oven: Set your oven to 350°F (175°C). Line an 8×8-inch metal baking pan with parchment paper and spray it lightly with nonstick cooking spray to ensure easy removal of the cake.
Mix dry ingredients: In a large bowl, whisk together all-purpose flour, unsweetened cocoa powder, light brown sugar, fine sea salt, and baking soda. This ensures your leavening agents and flour are evenly distributed.
Combine wet ingredients: In a separate small bowl, whisk together the melted unsalted butter, vegetable oil, room-temperature sour cream or yogurt, eggs plus extra yolk, and vanilla extract until smooth and fully incorporated.
Incorporate wet and dry mixtures: Make a well in the center of the dry ingredients and pour in the wet mixture. Stir gently until just combined with a few flour streaks remaining to avoid overmixing, which can make the cake tough.
Add zucchini and chocolate chips: Squeeze any excess moisture from the shredded zucchini before folding it into the batter along with the semisweet chocolate chips. Mix until barely combined to keep the texture light.
Bake the cake: Pour the batter evenly into the prepared baking pan. Bake in the oven for about 30 minutes or until a toothpick inserted into the center comes out clean. Expect slight sinking in the middle due to moisture, which is normal.
Cool the cake: Remove the cake from the oven and allow it to cool completely in the pan before frosting.
Prepare the glaze: In a medium bowl, stir together sifted powdered sugar and milk until smooth, thick yet pourable, forming a simple glaze.
Glaze the cake: Drizzle the powdered sugar glaze evenly over the cooled cake. Let it set before slicing and serving to allow the glaze to firm up slightly.
Storage: Store the cake in an airtight container at room temperature for up to 4 days to maintain freshness.

Notes

Squeezing out excess moisture from zucchini is crucial to prevent the cake from becoming gummy.
You can substitute sour cream with plain whole milk yogurt at room temperature.
If you prefer a richer cake, use full-fat dairy ingredients.
Ensure eggs and dairy are at room temperature for best mixing results.
Do not overmix the batter once wet and dry ingredients are combined to keep the cake tender.
The cake may sink slightly in the middle after baking because of its moisture content — this is normal.
Powdered sugar glaze adds sweetness without overpowering the rich chocolate flavor.
Use parchment paper for easier cake removal and cleanup.
