Ingredients

Scale
  • 2 cups (250g) all-purpose flour
  • 1 ½ tsp baking powder
  • 1 tsp baking soda
  • 1 tsp ground cinnamon
  • ½ tsp ground nutmeg
  • ¼ tsp ground ginger (optional)
  • ½ tsp salt
  • 1 cup (200g) granulated sugar
  • ½ cup (100g) brown sugar, packed
  • 2 large eggs, room temperature
  • ½ cup (120ml) vegetable oil or melted coconut oil
  • 1 tsp pure vanilla extract
  • 2 cups (about 300g) grated zucchini, squeezed dry
  • 8 oz (225g) cream cheese, softened
  • ¼ cup (60g) unsalted butter, softened
  • 1 cup (120g) powdered sugar, sifted
  • 2 tbsp pure maple syrup (grade A dark)
  • ½ tsp pure vanilla extract

Instructions

  1. Preheat your oven to 350°F (175°C) and grease your 9×13-inch sheet pan with butter or nonstick spray. Line it with parchment paper if desired.
  2. Grate 2 cups of zucchini using a box grater or food processor. Place the shredded zucchini in a clean kitchen towel and squeeze firmly to remove excess moisture.
  3. In a large bowl, whisk together flour, baking powder, baking soda, cinnamon, nutmeg, ginger (if using), and salt.
  4. In another bowl, beat together granulated sugar, brown sugar, eggs, vegetable oil, and vanilla extract until smooth and slightly thickened, about 2-3 minutes.
  5. Gradually add the dry mixture to the wet, mixing gently with a spatula until just combined. Avoid overmixing.
  6. Fold in the squeezed zucchini carefully to distribute evenly.
  7. Pour the batter into the prepared sheet pan and spread evenly.
  8. Bake for 35-40 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  9. Cool the cake completely in the pan on a wire rack for at least 30 minutes.
  10. For the frosting, beat cream cheese and butter until smooth. Gradually add powdered sugar, beating well after each addition.
  11. Mix in maple syrup and vanilla extract until fluffy.
  12. Spread the frosting evenly over the cooled cake. Chill for 10-15 minutes to set if desired.
  13. Slice into squares and serve.

Notes

Squeeze zucchini well to avoid soggy cake. Avoid overmixing batter to keep cake tender. Use dark grade maple syrup for richer frosting flavor. If batter is too thick, add 1-2 tablespoons of milk. Frost only when cake is completely cool to prevent melting.
