Easy Lemon Zucchini Cake with Cream Cheese Frosting
Discover this moist Lemon Zucchini Cake bursting with bright lemony flavor and wholesome zucchini for extra tenderness. Topped with luscious cream cheese frosting, it’s the perfect all-season cake for breakfast with coffee, snacks, or spring/summer dessert!
I originally made this cake in a 9×13 baking pan, and it turned out great. Everyone loved it for zucchini season. When my daughter made this again the other day, she turned it into a round two-layered cake with a cream cheese filling and topping on top. I loved it! Since both came out great, we thought we’d give you instructions for both so you can bake them to suit your needs!
This delicious lemon zucchini cake combines citrus flavor with shredded zucchini to create a moist, tender crumb structure suitable for breakfast, snacks, or dessert.
The cake requires a two-stage mixing process: dry ingredients are combined separately, then incorporated into wet ingredients mixed with shredded zucchini.
Cream cheese frosting for this cake is made by beating softened butter and cream cheese together before gradually adding powdered sugar and vanilla extract. The cake bakes at 350°F for approximately 33-45 minutes (depending on which baking pan you use) and must cool completely before frosting is applied.
The courgette or zucchini acts as a moisture-enhancing ingredient in baked goods while adding nutritional value without dominating the flavor profile. Perfect when you want to hide vegetables for your picky kids!
Why This Easy Lemon Zucchini Cake Works
This lemon zucchini cake recipe is designed for both flavor and texture. The combination of buttermilk, oil, and zucchini creates an incredibly moist crumb that stays soft for days. Unlike traditional cakes that rely solely on butter, cakes made with vegetable oil ensure consistent moisture throughout.
Fresh lemon juice adds a subtle citrus brightness that balances the sweetness, making it perfect for those who prefer desserts that aren’t overly sugary. The addition of chopped pecans or walnuts introduces a light crunch, giving this cake a bakery-style finish.
If you’re searching for an easy zucchini cake with cream cheese frosting, this recipe delivers a reliable, foolproof result every time.
What are the ingredients for the Lemon Zucchini Cake?
For the Cake
- 3 cups all-purpose flour
- 1 tsp baking powder
- 1/2 tsp baking soda
- 1 tsp ground cinnamon
- 1/2 tsp salt
- 3 large eggs – room temperature, lightly beaten.
- 1/2 cup vegetable oil
- 3/4 cup buttermilk
- 2 tbsp lemon juice
- 1/2 tsp vanilla extract – optional.
- 1 1/2 cups sugar – white and brown sugar combo
- 2 cups shredded zucchini
- 2/3 cup chopped pecans or walnuts
For the Frosting
- 1/2 cup unsalted Butter, softened.
- 1 (8oz) package cream cheese, softened.

How to Make Lemon Zucchini Cake with Cream Cheese Frosting?
Preheat the oven to 350 F. Whisk to combine the flour, baking powder, baking soda, ground cinnamon (optional), and salt in a bowl. Set aside.
Mix together the sugar, beaten egg, oil, buttermilk, lemon juice, and vanilla extract. Add the shredded zucchini.
Slowly add the flour mixture, mixing just until combined. Fold in pecans or walnuts. Spoon the cake batter into two round cake pans or a 9×13 baking pan, and bake. Use this as a guide:
- 9-inch pans: Bake 30–35 minutes
- 8-inch pans: Bake 33–38 minutes
- 9×13 pan: Bake for about 40-50 minutes.
Start checking at the lower time. The cakes are done when a toothpick inserted in the center comes out clean or with a few moist crumbs. The tops should spring back lightly when touched.
Let the cakes cool in the pans for 10–15 minutes, then turn them out onto a wire rack to cool completely (about 1–2 hours).
For the Cream Cheese Frosting
Make the cream cheese frosting. Using an electric mixer, beat together the softened butter and cream cheese until smooth. On low speed, add the powdered sugar one cup at a time, continuing until the mixture is smooth and creamy. Beat in the Vanilla extract until it’s incorporated.
If doing the two-tiered cake:
Place one cooled layer on a plate or cake stand. Spread a generous layer of frosting on top (the filling). Add the second layer and frost the top and sides. For a pretty finish: pipe extra frosting swirls on top, sprinkle with lemon zest and chopped nuts, and add fresh or caramelized lemon slices.
Simply spread the cream cheese frosting evenly on top of the cooled cake if using a 9×13 pan. Serve immediately or store in the refrigerator until serving time.
Frequently Asked Questions (FAQs)
Can I freeze lemon zucchini cake with cream cheese frosting already applied?
It’s better to freeze the cake unfrosted and add the cream cheese frosting after thawing. Cream cheese frosting can become watery and separate when frozen and thawed, affecting both texture and appearance. Wrap the unfrosted cake tightly in plastic wrap, then aluminum foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before frosting and serving.
How do I prevent my zucchini from turning the cake batter green?
While small flecks of green are normal and generally unnoticeable in the baked cake, you can minimize discoloration by peeling the zucchini before shredding or by choosing lighter-colored, younger zucchini. The lemon juice in the recipe also helps maintain a lighter crumb color. Once baked and topped with white cream cheese frosting, any slight color variation becomes virtually invisible.
What’s the best way to measure shredded zucchini accurately?
Shred your zucchini, then lightly pack it into a measuring cup without squeezing or pressing it down hard. The recipe calls for the zucchini with its natural moisture intact, so don’t drain it unless it’s excessively watery. Two cups of shredded zucchini typically equals about 2 medium zucchini (approximately 8-10 inches long).
Can I substitute Greek yogurt for the buttermilk in this recipe?
Yes, you can substitute an equal amount of thinned Greek yogurt for buttermilk. Mix 3/4 cup Greek yogurt with 1/4 cup milk to achieve a similar consistency and acidity level to 1 cup buttermilk. This substitution will work well with the lemon juice and baking soda to provide proper leavening while maintaining the cake’s tender texture.
How long will this cake stay fresh, and does it need refrigeration?
Because this cake is topped with cream cheese frosting, it should be refrigerated and will stay fresh for 4-5 days when stored in an airtight container. Bring individual slices to room temperature for 15-20 minutes before serving for the best flavor and texture. The unfrosted cake can be stored at room temperature for 2-3 days if you plan to frost it later.
Things to consider!
#1 Zucchini adds moisture and tenderness without contributing strong vegetable flavor to baked goods, making it an ideal ingredient for creating cakes with soft, moist crumb structure while adding nutritional value that enhances rather than compromises dessert quality.
#2 Complete cooling of the cake before frosting application is non-negotiable because applying cream cheese frosting to a warm cake causes the butter and cream cheese to melt, resulting in a runny, sliding frosting that won’t set properly even after refrigeration.
#3 The two-stage mixing method prevents overmixing by keeping dry ingredients separate until the final combination step, which preserves the tender texture by minimizing gluten development that would otherwise create a tough, dense cake.
#4 Lemon juice serves a dual purpose in this recipe by providing bright citrus flavor while also reacting with baking soda to create chemical leavening that helps the cake rise and develop its characteristic light texture.
#5 Cream cheese frosting requires softened dairy ingredients at room temperature to achieve a smooth, lump-free consistency, as cold cream cheese and butter won’t blend properly and will create a grainy frosting with an uneven texture that’s difficult to spread.
This homemade lemon zucchini cake is ideal for spring and summer gatherings, brunch tables, or as a light dessert after a hearty meal. Its balance of sweetness and citrus makes it appealing to a wide range of tastes.
It’s also a fantastic way to use up extra zucchini during peak season, transforming a simple vegetable into a bakery-quality dessert that feels both indulgent and fresh. If you’re looking for a delicious dessert recipe to use with your summer squash or zucchini, make sure to add this recipe to your list.
