Zucchini cake is a moist, tender dessert that cleverly incorporates shredded zucchini to add moisture and subtle earthiness without overpowering the sweetness. Whether you opt for a quick box mix version or a fully homemade recipe, zucchini cake works because the vegetable keeps it soft and flavorful, making it a perfect year-round treat.
Ingredients
- For the Box Mix Version:
- 1 box yellow cake mix (about 15.25 oz)
- 1 teaspoon ground cinnamon
- 3 large eggs
- 1/3 cup vegetable oil
- 1 1/2 cups shredded zucchini (about 1 medium zucchini)
- 1 teaspoon vanilla extract
- Optional: 1/2 cup chopped walnuts or pecans
- For the Homemade Version:
- 2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg (optional)
- 3 large eggs
- 1 cup granulated sugar
- 1/2 cup packed light brown sugar
- 1 cup vegetable oil or melted coconut oil
- 2 teaspoons vanilla extract
- 1 1/2 to 2 cups shredded zucchini (about 2 medium zucchinis)
- 1/2 cup chopped walnuts or pecans (optional)
- 1/2 cup raisins or mini chocolate chips (optional)
Instructions
- Box Mix Version:
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper.
- In a large mixing bowl, combine the cake mix and ground cinnamon.
- Add eggs, vegetable oil, and vanilla extract to the dry mix. Beat with an electric mixer on medium speed for 2 minutes until smooth.
- Fold in shredded zucchini and nuts (if using) by hand until evenly distributed.
- Pour batter into the prepared pan and spread evenly.
- Bake for 30-35 minutes or until a toothpick inserted in the center comes out clean.
- Remove from oven and let cool completely in the pan on a wire rack before slicing.
- Homemade Version:
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan or line it with parchment paper.
- In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
- In a large bowl, beat eggs, granulated sugar, brown sugar, oil, and vanilla extract until combined and smooth.
- Gradually add the dry ingredients to the wet ingredients, mixing on low speed or folding with a spatula just until combined. Avoid overmixing to keep the cake tender.
- Fold in shredded zucchini, nuts, and raisins or chocolate chips if using.
- Pour batter into the prepared pan and smooth the top.
- Bake for 45-55 minutes, checking doneness at 45 minutes with a toothpick. It should come out clean or with a few moist crumbs.
- Cool completely in the pan on a wire rack before slicing.
Tips
- Grate and Drain Zucchini: For both recipes, shred zucchini finely and gently squeeze out excess moisture with a clean kitchen towel or paper towels to prevent a soggy cake.
- Substitutions: You can substitute half the all-purpose flour with whole wheat pastry flour in the homemade recipe for added nutrition and a heartier texture. Unsweetened applesauce can replace half the oil for a lighter cake.
- Storage: Store zucchini cake tightly wrapped or in an airtight container at room temperature for up to 3 days or refrigerated for up to 1 week. It freezes well for up to 3 months.
- Common Mistakes: Avoid overmixing the batter to prevent a dense texture, and be sure to bake the cake fully to avoid a wet center. Using freshly grated zucchini gives the best flavor and moisture balance.
Serving Suggestions
Zucchini cake is delicious on its own but can be elevated with a simple cream cheese frosting or a dusting of powdered sugar. For a breakfast or brunch option, serve slices with a smear of butter or alongside fresh fruit and yogurt. It also pairs well with a hot cup of tea or coffee for an afternoon snack.
Variations
- Spice it Up: Add 1/2 teaspoon ground ginger or allspice along with cinnamon to deepen the flavor profile.
- Chocolate Zucchini Cake: Add 1/3 cup unsweetened cocoa powder to the dry ingredients and fold in mini chocolate chips.
- Vegan Version: Use a vegan box cake mix or substitute eggs with flax eggs (1 tablespoon ground flaxseed + 3 tablespoons water per egg) and use plant-based milk in the homemade recipe.
- Nut-Free: Omit nuts or swap for sunflower seeds for crunch if allergies are a concern.
Storage and Reheating
Store leftover zucchini cake in an airtight container at room temperature for up to 3 days. Refrigerate if your kitchen is warm or if the cake is frosted; it will keep for up to 1 week. To freeze, wrap the cake tightly in plastic wrap and place it in a freezer-safe bag or container for up to 3 months. Thaw overnight in the refrigerator or at room temperature before serving.
Reheat individual slices in the microwave for 10-15 seconds to restore softness. Avoid overheating to prevent drying out. Alternatively, warm slices in a 300°F (150°C) oven for 5-7 minutes wrapped loosely in foil.
Frequently Asked Questions
Can I use yellow squash instead of zucchini in this cake?
Yes, yellow squash can be used in place of zucchini in equal amounts. It has a similar moisture content and mild flavor, so it won’t affect the texture or taste significantly.
Do I need to peel the zucchini before shredding?
No, peeling is not necessary. The skin is thin and adds a nice green speckled appearance and extra nutrients. Just be sure to wash the zucchini well.
Why is my zucchini cake dense or wet in the middle?
This often happens if the zucchini wasn’t drained properly or the cake was underbaked. Make sure to squeeze out excess moisture from the zucchini and test doneness with a toothpick before removing from the oven.
Can I make zucchini cake in muffin form?
Absolutely! Adjust the baking time to about 18-22 minutes at 350°F (175°C) and fill muffin cups about 2/3 full. Muffins are a great portable snack version.
Is zucchini cake healthy?
While zucchini adds moisture and some vitamins, zucchini cake is still a sweet baked good with sugar and oil. It’s a tasty way to add veggies to your diet but best enjoyed as an occasional treat.
How do box mix and homemade versions compare in flavor and texture?
The box mix version is quicker and more consistent but can taste slightly sweeter and less complex. The homemade version allows for more control over spices, sugar, and add-ins, often resulting in a richer, more balanced flavor and a moister crumb. Both are delicious, so choose based on your time and taste preferences.
Can I add frosting to zucchini cake?
Cream cheese frosting is a classic pairing that adds tang and richness, complementing the spice and moisture of the cake. For a lighter option, a simple glaze made from powdered sugar and lemon juice or milk works well too.
