This Zucchini Cake is an easy sheet cake recipe packed with fresh zucchini and flavored with late summer, early fall spices. Moist and tender, and topped with cream cheese frosting, it's a cake with deep roots and delicious flavor.
Preheat oven to 350°F and butter a 9x13 baking pan.
In a bowl, whisk together the flour, baking soda, baking powder, cinnamon, allspice, and salt; set aside.
With a mixer, beat the eggs until frothy; about 2 to 3 minutes. Then beat in the sugar, cooking oil, and vanilla. Fold in the flour mixture followed by the zucchini and chopped nuts.
Transfer the batter into the prepared 9x13 baking pan. Bake for 40 to 45 minutes, or until a toothpick comes out mostly clean. Remove from the oven and let cool completely.
Cream Cheese Frosting
Beat together the cream cheese and butter. Then add the powdered sugar and beat until smooth. For the best flavor, frost the cake just before serving.
Notes
Zucchini: You will need 2 cups of shredded zucchini, which will equal about 3 medium-sized zucchini. A medium zucchini measures about 6 to 7 inches in length. To prepare, shred the zucchini and lay it on top of several layers of paper towels. Gather into a bundle and squeeze out any excess moisture.
Freezing: Wrap unfrosted cake in plastic wrap, then foil. Freeze up to 2 months.
Variations: Add 1 cup chopped pecans instead of walnuts or swap spices for pumpkin pie spice for a stronger autumn flavor.
Frosting Storage: Refrigerate frosted cake in an airtight container up to 5 days. Bring to room temperature before serving.
