Description

This reliable Zucchini Spice Cake features a perfectly tender crumb balanced by warm spices and a rich cream cheese frosting. By using a precise ratio of oil and starch, this recipe ensures a stable, delicious result without the need to squeeze water from the zucchini.


Ingredients

  • 210 grams all-purpose flour
  • 30 grams cornstarch
  • 3/4 teaspoon baking soda
  • 1 1/2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 2 1/2 teaspoons ground cinnamon
  • 1/4 teaspoon nutmeg
  • 300 grams light brown sugar
  • 2 large eggs
  • 120 grams whole milk
  • 160 grams vegetable oil
  • 2 1/2 teaspoons vanilla extract
  • 190 grams freshly shredded zucchini
  • 100 grams chopped walnuts
  • 112 grams unsalted butter, softened
  • 215 grams powdered sugar
  • 167 grams cold cream cheese
  • 1 teaspoon fresh lemon juice


Instructions

  1. Prep the oven. Preheat your conventional oven to 350°F (177°C) and grease a 9×13-inch metal pan, lining it with a parchment paper sling.
  2. Sift dry ingredients. Whisk together the flour, cornstarch, baking soda, baking powder, salt, cinnamon, and nutmeg until well combined.
  3. Mix wet ingredients. Combine the brown sugar, eggs, milk, oil, and vanilla, then stir in the freshly shredded zucchini.
  4. Fold in batter. Gently fold the dry mixture into the wet ingredients until no flour streaks remain, taking care not to overmix.
  5. Incorporate the nuts. Scatter the chopped walnuts over the batter and fold them in with exactly three gentle strokes.
  6. Pour and level. Transfer the batter to the prepared pan, smooth the surface, and tap the pan firmly to release air pockets.
  7. Bake the cake. Bake for 25 minutes or until an instant-read thermometer reaches 205°F (96°C) in the center.
  8. Cool the cake. Rest the pan on a wire rack for 20 minutes before lifting the cake out to cool completely.
  9. Prepare the frosting. Cream the butter, sugar, cream cheese, vanilla, and lemon juice until smooth and uniform.
  10. Frost and slice. Spread the frosting over the cooled cake, let it set for 10 minutes, and slice into twelve equal squares.

Notes

  • Use a kitchen scale for measuring flour to maintain the precise liquid-to-dry ratio.
  • Avoid pre-packaged grated zucchini as it lacks the moisture needed for a tender crumb.
  • Bring eggs and milk to room temperature before mixing to ensure a stable emulsion.
  • Use metal baking pans rather than glass for more even heat distribution and better browning.
  • Dip your knife in warm water between cuts to ensure clean, professional-looking cake slices.
