Ingredients

Scale

Lemon Zucchini Cake

  • 2 3/4 cups (358g) all-purpose flour
  • 1 3/4 teaspoons baking powder
  • 1/4 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1/2 cup (112g) unsalted butter, room temperature
  • 1/2 cup (120ml) vegetable oil
  • 1 1/2 cups (310g) sugar
  • 2 tablespoons fresh lemon zest
  • 1/2 teaspoon vanilla extract
  • 4 large eggs
  • 1/4 cup (180ml) milk
  • 1/2 cup (120ml) fresh lemon juice
  • 2 1/4 cups (270g) shredded zucchini

Cream Cheese Frosting

  • 8 oz (226g) cream cheese, room temperature
  • 6 tablespoons (86g) unsalted butter, room temperature
  • 4 cups (460g) powdered sugar
  • 1 teaspoon vanilla extract


Instructions

  1. Preheat oven to 350°F (176°C) and prepare a 9×13-inch cake pan with non-stick baking spray.
  2. Combine the flour, baking powder, baking soda and salt in a medium-sized bowl and set aside.
  3. Add the butter, oil, sugar, lemon zest and vanilla extract to a large mixer bowl and beat together until light in color and fluffy, about 2-3 minutes. Do not skimp on the creaming time.
  4. Add the eggs one at a time, mixing until mostly combined after each. Scrape down the sides of the bowl as needed to be sure all ingredients are well incorporated.
  5. Add half of the dry ingredients to the batter and mix until mostly combined.
  6. Combine the milk and lemon juice, then slowly add the mixture to the batter and mix until well combined.
  7. Add the remaining dry ingredients and mix until well combined and smooth.
  8. Add the zucchini and gently fold together. Scrape down the sides of the bowl as needed to be sure all ingredients are well incorporated. Do not over mix the batter.
  9. Pour the batter into the prepared cake pan and bake for 28-33 minutes, or until a toothpick comes out clean.
  10. Remove the cake from the oven and allow to cool completely before adding the frosting.
  11. To make the cream cheese frosting, add the cream cheese and butter to a large mixing bowl. Beat on medium speed until well combined and smooth.
  12. Add about half of the powdered sugar and mix until well combined and smooth, then add the vanilla extract and mix until well combined.
  13. Add the remaining powdered sugar and mix until well combined.
  14. Spread the frosting evenly on top of the cake and then decorate as desired.
  15. Slice and serve, or refrigerate until ready to serve. The frosting will firm up when cold, so I recommend serving the cake just slightly cool, or at room temperature. Cake is best when eaten within 4-5 days.
