This refined Zucchini Spice Cake pairs a moist, tender crumb with a luxurious cream cheese frosting. It balances subtle warm spices and garden-fresh squash for a sophisticated, patisserie-quality dessert.


Ingredients

  • 2 cups all-purpose flour
  • 1/4 cup cornstarch
  • 1 tsp baking soda
  • 1 tsp baking powder
  • 1/2 tsp salt
  • 1.5 tsp ground cinnamon
  • 1/2 tsp ground nutmeg
  • 1 1/2 cups light brown sugar
  • 3 large eggs, room temperature
  • 1/2 cup whole milk, room temperature
  • 3/4 cup canola oil
  • 1 tsp vanilla extract
  • 2 cups finely grated zucchini
  • 1/2 cup chopped walnuts
  • 8 oz block cream cheese, cold
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 1 tsp lemon juice


Instructions

  1. Prepare the oven. Preheat your oven to 180°C (350°F) and prepare a 9×13-inch baking pan with grease and parchment paper.
  2. Sift dry ingredients. Combine flour, cornstarch, baking soda, baking powder, salt, cinnamon, and nutmeg in a bowl and whisk thoroughly.
  3. Emulsify wet base. Whisk brown sugar, eggs, milk, oil, vanilla, and grated zucchini in a large bowl until a stable emulsion forms.
  4. Fold the batter. Incorporate dry ingredients into the wet mixture using a spatula, mixing only until just combined to prevent gluten development.
  5. Incorporate the nuts. Gently fold in the chopped walnuts until they are evenly distributed throughout the thick batter.
  6. Bake the cake. Pour the batter into the prepared pan and bake for 25 minutes or until a skewer inserted in the center comes out clean.
  7. Cool the cake. Allow the cake to rest in the pan for 20 minutes before inverting it onto a wire rack to cool completely.
  8. Beat butter base. Whip the softened butter in a stand mixer until pale and airy, then gradually add powdered sugar.
  9. Add cheese and acid. Mix in the cold cream cheese, vanilla, and lemon juice until the frosting is smooth and holds a firm peak.
  10. Frost and finish. Apply the frosting to the cooled cake with an offset spatula and let it stabilize for ten minutes before slicing.

Notes

  • Ensure all dairy and egg components are at room temperature to achieve a perfect emulsion.
  • Use a box grater for the zucchini to maintain structural integrity and prevent excess liquid.
  • Wipe your knife with a warm, damp cloth between cuts to ensure professional-looking, clean slices.
  • Chill the frosting briefly if it becomes too soft during application to ensure sharp, decorative swirls.
