Ingredients for Easy Lemon Zucchini Cake
For the Lemon Zucchini Cake
- 2 cups grated zucchini – Adds natural moisture and keeps the cake soft without a noticeable vegetable flavor. No need to peel the zucchini before grating.
- 3 cups all-purpose flour – Provides the structure for the cake. Spoon and level the flour instead of scooping directly from the bag for the best texture.
- 1 teaspoon baking soda – Reacts with the lemon juice to help the cake rise and create a tender crumb.
- 1 teaspoon baking powder – Gives the cake extra lift for a light, fluffy texture.
- 1¾ cups granulated sugar – Sweetens the cake while balancing the bright citrus flavor.
- 3 tablespoons fresh lemon zest – Adds bold, fresh lemon flavor and a wonderful citrus aroma.
- 1 cup vegetable oil – Keeps the cake moist and tender for several days.
- ⅓ cup sour cream – Adds richness, creaminess, and a subtle tang that complements the lemon.
- ¼ cup fresh lemon juice – Brings a fresh, vibrant citrus taste that’s much brighter than bottled juice.
- 3 large eggs – Bind the ingredients together and create a sturdy yet soft cake.
For the Lemon Glaze

How to Make Homemade Lemon Zucchini Cake
1. Prepare the Oven and Pan
Preheat your oven to 350°F (175°C) and position a rack in the center. Generously grease a 10-cup Bundt pan, including the center tube, to ensure the cake releases easily after baking.
2. Prepare the Zucchini and Dry Ingredients
Grate the zucchini using the large holes of a box grater, but don’t squeeze out the moisture since it helps create a soft, moist cake. In a medium bowl, whisk together the all-purpose flour, baking soda, baking powder, and salt until well combined.
3. Mix the Wet Ingredients
In a large mixing bowl, rub the granulated sugar and fresh lemon zest together with your fingertips for about a minute to release the natural citrus oils. Add the vegetable oil, sour cream, fresh lemon juice, vanilla extract, and eggs, then whisk until the mixture is smooth.
4. Combine the Batter
Gradually fold the dry ingredients into the wet ingredients using a spatula. Mix just until no dry streaks remain, then gently fold in the grated zucchini until evenly distributed. Avoid overmixing to keep the cake light and tender.
5. Bake the Cake
Pour the batter into the prepared Bundt pan and smooth the top. Bake for 50 to 55 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.
6. Cool the Cake
Let the cake cool in the pan for 15 minutes before carefully inverting it onto a wire rack. Allow it to cool completely before glazing so the topping sets properly.
7. Make the Lemon Glaze
Whisk the fresh lemon juice and powdered sugar together until smooth and pourable. Drizzle the glaze evenly over the cooled cake and let it set for about 10 minutes before slicing and serving.
Expert Tips for the Best Lemon Zucchini Cake
Choose Fresh, Smaller Zucchini
Use small or medium zucchini whenever possible. They have a milder flavor, fewer seeds, and a more tender texture. If you’re using a large zucchini, trim off both ends before grating to avoid any bitterness.
Zest the Lemons First
Always zest the lemons before squeezing the juice. It’s much easier to remove the zest from whole lemons, and you’ll get the maximum fresh citrus flavor for the cake.
Measure the Flour Correctly
Spoon the flour into the measuring cup and level it with a knife instead of scooping directly from the bag. This prevents adding too much flour, which can make the cake dense and dry.
Grease the Bundt Pan Well
Coat every part of the Bundt pan, including the center tube and all the grooves, with butter or baking spray. Proper greasing helps the cake release easily without sticking.
Cool Before Adding the Glaze
Allow the cake to cool completely on a wire rack before drizzling on the lemon glaze. This helps the glaze set beautifully and creates a smooth, even finish.
Test for Doneness Early
Begin checking the cake after 50 minutes by inserting a toothpick into the center. If it comes out clean or with a few moist crumbs, the cake is ready to remove from the oven.
Ingredient Substitutions for Lemon Zucchini Cake
Replace the Sour Cream
If you don’t have sour cream, use the same amount of plain full-fat Greek yogurt. It provides a similar creamy texture with a slightly tangier flavor while keeping the cake moist.
Use a Different Oil
Vegetable oil can be replaced with canola oil or light olive oil in equal amounts. Both options create a soft, tender crumb without noticeably changing the flavor.
Make It Gluten-Free
For a gluten-free version, substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The cake may be slightly denser, but it will still bake up soft and moist.
Make It Dairy-Free
Replace the sour cream with your favorite dairy-free plain yogurt alternative. It adds moisture and richness while keeping the cake dairy-free.
Fresh vs. Bottled Lemon Juice
Fresh lemons deliver the brightest citrus flavor, so they’re the best choice for the cake batter. If needed, bottled lemon juice can be used for the glaze, but fresh lemon zest is highly recommended for the best taste.
How to Store Lemon Zucchini Cake
Store at Room Temperature
Keep the glazed Lemon Zucchini Cake covered in an airtight container at room temperature for up to 4 days. The grated zucchini helps the cake stay soft and moist longer than many traditional cakes.
Refrigerate for Longer Freshness
If your kitchen is warm, store the cake in the refrigerator for up to 1 week. For the best texture and flavor, let each slice come to room temperature before serving.
Freeze for Later
To freeze, wrap the unglazed cake tightly in plastic wrap followed by a layer of aluminum foil. Freeze for up to 3 months. Thaw overnight at room temperature, then add the fresh lemon glaze just before serving for the best results.

Yes. This cake is a great make-ahead dessert because it stays moist for several days. Bake it a day in advance, let it cool completely, then glaze it before serving for the freshest flavor.

No. The zucchini skin becomes soft as the cake bakes and blends into the crumb. Simply wash the zucchini well before grating.
