Ingredients
- 1 cup vegetable oil
- 2 cups granulated sugar
- 2 large eggs
- 1/2 cup buttermilk
- 2 tsp vanilla extract
- 1 1/2 tsp cinnamon
- 2 cups all-purpose flour
- 1/2 tsp baking soda
- 1/2 tsp baking powder
- 1/2 tsp salt
- 2 cups lightly packed shredded zucchini
- 1 cup finely chopped walnuts
- 8 ounces cream cheese, completely soft
- 6 Tbsp unsalted butter, soft
- 3 cups confectioner’s sugar
- Lemon juice, about 1 Tbsp
Key Ingredient Explanations
- Zucchini: This vegetable adds moisture and nutrition while remaining nearly undetectable in flavor.
- Buttermilk: It adds tenderness and a subtle tang that enhances the overall taste of the cake.
- Cream Cheese: Provides the perfect smooth texture for frosting, contrasting beautifully with the moist cake.
Ingredient Notes and Easy Substitutions
- Vegetable Oil: You can substitute this with canola or melted coconut oil for a different flavor profile.
- Buttermilk: In a pinch, mix 1/2 cup of milk with 1/2 tablespoon of vinegar or lemon juice, letting it sit a few minutes before using.
- Walnuts: Feel free to swap these out for pecans or omit them entirely based on preference.
Instructions
- Preheat the oven to 350°F (175°C). Spray a 9×13-inch pan with cooking spray to prevent sticking.
- Prepare the Liquid Ingredients: In a large mixing bowl, whisk together the vegetable oil, granulated sugar, eggs, buttermilk, vanilla extract, and cinnamon until the mixture is smooth and well combined.
- Combine Dry Ingredients: In a separate bowl, toss together the flour, baking soda, baking powder, and salt. Gradually add this to the liquid mixture, mixing just until completely blended.
- Fold in Zucchini and Nuts: Gently fold in the shredded zucchini and finely chopped walnuts until evenly distributed throughout the batter.
- Bake: Turn the batter into your prepared pan and bake for approximately 40 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- Cool Completely: Allow the cake to cool completely in the pan before frosting.
- Make the Frosting: In a mixing bowl, beat together the cream cheese and soft butter until light and fluffy. Gradually add the confectioner’s sugar, one cup at a time, while continuing to beat, and then mix in the lemon juice. Adjust the frosting consistency as needed by adding more sugar or a little milk if too thin.
- Frost and Serve: Once the cake has cooled, evenly spread the cream cheese frosting on top, slice, and enjoy!
Expert Tips for the Best Results
- Measure Your Zucchini Carefully: Make sure to lightly pack the shredded zucchini when measuring to avoid adding too much moisture.
- Check Doneness Early: Since oven temperatures can vary, start checking for doneness at 35 minutes.
- Chill the Frosting: If it’s too soft, refrigerate the frosting for a few minutes before spreading it on the cake to help set it.
Variations
- Chocolate Chip Zucchini Cake: Add a cup of chocolate chips to the batter for a delicious twist.
- Spiced Zucchini Cake: Incorporate additional spices like nutmeg or ginger for more warmth.
- Coconut Zucchini Cake: Fold in shredded coconut for a tropical flavor addition.
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend for a gluten-free version.
Serving Suggestions
Zucchini Sheet Cake with Cream Cheese Frosting pairs well with coffee or tea for an afternoon treat. Consider serving it with fresh fruit or a scoop of vanilla ice cream for dessert. Garnish slices with extra chopped walnuts or a sprinkle of cinnamon for added visual appeal.

Common Mistakes to Avoid
