How to Make Zucchini Olive Oil Cake:
Quick Overview
This zucchini olive oil cake is surprisingly simple to make and delivers restaurant-quality results every time. The secret lies in properly preparing the zucchini and using high-quality olive oil for maximum flavor impact.
Preparation Time: 15 minutes Baking Time: 45-55 minutes Total Time: 1 hour 10 minutes Serves: 8-10 people
Key Ingredients for Zucchini Olive Oil Cake:
Dry Ingredients:
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 1/2 cup brown sugar, packed
- 1 1/2 teaspoons baking powder
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground nutmeg
Wet Ingredients:
- 3/4 cup extra virgin olive oil
- 3 large eggs, room temperature
- 1/4 cup milk
- 2 teaspoons vanilla extract
- 1 teaspoon lemon zest (optional)
Star Ingredient:
- 2 cups zucchini, grated and excess moisture removed
- 1/2 cup chopped walnuts (optional)

Step-by-Step Instructions:
Prepare Your Kitchen
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan or two 9-inch round pans with olive oil and dust with flour. Line the bottom with parchment paper for easy removal.
Prepare the Zucchini
Wash and grate 2-3 medium zucchini using a box grater’s large holes. Place the grated zucchini in a clean kitchen towel and squeeze firmly to remove excess moisture. This step is crucial for preventing a soggy cake. Set aside the drained zucchini.
Mix Dry Ingredients
In a large mixing bowl, whisk together flour, both sugars, baking powder, baking soda, salt, cinnamon, and nutmeg until well combined. This ensures even distribution of leavening agents and spices throughout the cake.
Combine Wet Ingredients
In a separate medium bowl, whisk the olive oil, eggs, milk, vanilla extract, and lemon zest until smooth and well combined. The mixture should be emulsified and slightly thick.
Create the Batter
Pour the wet ingredients into the dry ingredients and gently fold together using a rubber spatula. Don’t overmix – stop as soon as you don’t see dry flour. Fold in the prepared zucchini and walnuts if using.
Bake to Perfection
Pour the batter into your prepared pan and spread evenly. Bake for 45-55 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs. The top should be golden brown and spring back when lightly touched.
Cool and Serve
Allow the cake to cool in the pan for 15 minutes before turning out onto a wire rack. Cool completely before frosting or dusting with powdered sugar.
What to Serve Zucchini Olive Oil Cake With:
This versatile cake pairs beautifully with various accompaniments depending on the occasion.
For Afternoon Tea: Serve with freshly whipped cream and a drizzle of honey, alongside hot tea or coffee.
For Dessert: Top with cream cheese frosting, vanilla ice cream, or a simple glaze made with powdered sugar and lemon juice.
For Breakfast: Enjoy a slice with Greek yogurt and fresh berries for a delightfully indulgent yet nutritious morning treat.
Beverage Pairings: Coffee, chai tea, or even a glass of cold milk complement the cake’s warm spices perfectly.

Top Tips for Perfecting Zucchini Olive Oil Cake:
Choose the Right Zucchini
Select medium-sized zucchini with firm skin and no soft spots. Avoid overly large zucchini as they contain more seeds and water, which can make the cake soggy.
Master the Moisture Balance
Always squeeze excess moisture from grated zucchini. Too much liquid will create a dense, gummy texture. Pat the zucchini dry with paper towels after squeezing for best results.
Ingredient Substitutions
You can replace up to half the all-purpose flour with whole wheat flour for added nutrition. For a dairy-free version, substitute the milk with almond or oat milk. Light olive oil works if you prefer a milder flavor.
Avoid Common Mistakes
Don’t overmix the batter once you add the flour – this develops gluten and creates a tough cake. Room temperature eggs incorporate better, so take them out 30 minutes before baking.
Enhance the Flavor
Add a tablespoon of orange zest for citrus brightness, or fold in mini chocolate chips for extra indulgence. A pinch of cardamom or ginger can add sophisticated warmth.
Storing and Reheating Tips:
Room Temperature Storage
Store the unfrosted cake covered with plastic wrap or in an airtight container for up to 3 days at room temperature. The olive oil helps maintain moisture longer than butter-based cakes.
Refrigeration
Frosted cake should be refrigerated and will stay fresh for up to 5 days. Bring to room temperature before serving for the best texture and flavor.
Freezing Instructions
Wrap individual slices or the whole cake tightly in plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature before serving.
Reheating Methods
For a warm treat, microwave individual slices for 15-20 seconds. You can also warm slices in a 300°F oven for 5-7 minutes, covered with foil to prevent drying.

Frequently Asked Questions
Can I taste the zucchini in the cake?
No! When properly prepared, zucchini adds incredible moisture without any vegetable flavor. The warm spices and vanilla completely mask any zucchini taste, making this perfect for veggie-averse family members.
Do I need to peel the zucchini before grating?
You don’t need to peel young, tender zucchini with thin skin. However, if using larger zucchini with tough skin, peeling will give you a smoother texture in the finished cake.
Can I make this cake gluten-free?
Yes! Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Make sure your baking powder is also gluten-free. The texture will be slightly different but still delicious.
Why is my cake dense or gummy?
This usually happens from too much moisture (not squeezing the zucchini properly) or overmixing the batter. Always drain zucchini thoroughly and fold ingredients gently just until combined.
Can I use a different oil instead of olive oil?
Absolutely! Vegetable oil, canola oil, or melted coconut oil work well. Olive oil provides a subtle fruity flavor, but neutral oils work if you prefer a milder taste.
How do I know when the cake is done?
Insert a toothpick in the center – it should come out with just a few moist crumbs clinging to it. The top should be golden brown and spring back when lightly touched.
Can I add frosting to this cake?
Yes! Cream cheese frosting is classic, but simple powdered sugar glaze, vanilla buttercream, or even a dusting of powdered sugar all work beautifully.
Is this cake healthy?
While still a dessert, this cake contains vegetables, healthy fats from olive oil, and less butter than traditional cakes. It’s a more nutritious option that still satisfies your sweet tooth.
