Description

This classic farmhouse zucchini cake offers a perfectly tender, spiced crumb loaded with garden-fresh zucchini and crunchy walnuts. Topped with a rich cream cheese frosting, it is a timeless, humble dessert that stays wonderfully moist for days.


Ingredients

  • 2 cups all-purpose flour
  • 2 cups grated zucchini
  • 1 cup vegetable oil
  • 1 1/2 cups sugar
  • 3 large eggs
  • 1 teaspoon baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 tablespoon ground cinnamon
  • 1 teaspoon vanilla extract
  • 1/2 cup chopped black walnuts
  • 1/2 cup golden raisins
  • 1 tablespoon lemon zest (optional)
  • 8 ounces cream cheese, softened
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar


Instructions

  1. Prepare oven and pan. Preheat your oven to 350°F and thoroughly butter a 9×13 baking pan.
  2. Whisk dry ingredients. In a large bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon until uniform.
  3. Beat eggs and liquids. In a separate mixer bowl, beat the eggs until frothy, then gradually add the sugar, oil, vanilla, and optional lemon zest until glossy.
  4. Combine dry and wet. Turn the mixer to low and add the flour mixture in three additions, mixing just until the streaks disappear.
  5. Fold in extras. Gently fold in the grated zucchini, chopped walnuts, and golden raisins using a wooden spoon.
  6. Bake the cake. Spread the batter into the prepared pan and bake for 40 to 45 minutes, or until a tester comes out clean.
  7. Cool completely. Allow the cake to cool fully on a wire rack before attempting to apply any frosting.
  8. Make the frosting. Beat the softened cream cheese and butter until smooth, then gradually incorporate the powdered sugar until creamy.
  9. Frost and serve. Spread the frosting evenly over the cooled cake, creating decorative swirls with the back of a spoon if desired.

Notes

  • Press grated zucchini through a clean cloth to remove excess water for a better cake structure.
  • Toast walnuts in a dry skillet before adding to the batter to intensify their earthy flavor.
  • Ensure cream cheese and butter are at room temperature to avoid lumps in the frosting.
  • Tent the cake with foil during the final 15 minutes of baking if the top begins to brown too quickly.
