¾ cup (150 g) granulated sugar
½ cup (100 g) packed brown sugar
¾ cup (180 ml) neutral vegetable oil
3 large eggs, at room temperature
2 teaspoons vanilla extract
2 cups (about 250 g) freshly grated zucchini
½ cup (60 g) chopped walnuts or pecans, optional
For the Cream Cheese Frosting
8 oz (225 g) full-fat cream cheese, softened
½ cup (113 g) unsalted butter, softened
2½ cups (300 g) powdered sugar, sifted
1 teaspoon vanilla extract
Pinch of salt, optional
A quick zucchini tip: Grate the zucchini using the large holes of a box grater. If it is exceptionally watery, gently squeeze out some excess liquid with a clean kitchen towel. Avoid squeezing it completely dry, since some moisture helps keep the cake tender.
How to Make Cream Cheese Frosted Zucchini Cake
Step 1: Prepare the Pan and Oven
Preheat your oven to 350°F (175°C). Grease a 9-by-13-inch baking pan and line it with parchment paper if you want to remove the cake easily.
In a medium bowl, whisk together the flour, baking soda, baking powder, salt, cinnamon, and nutmeg. Set aside.
Step 2: Mix the Wet Ingredients
In a large mixing bowl, whisk the granulated sugar, brown sugar, and vegetable oil until combined.
Add the eggs one at a time, whisking after each addition. Stir in the vanilla extract.
The mixture should look smooth and evenly blended before you add the dry ingredients.
Step 3: Combine the Batter
Add the flour mixture to the wet ingredients in two or three additions, stirring gently until no large pockets of dry flour remain.
Fold in the grated zucchini using a spatula. If you're adding chopped walnuts or pecans, fold them in at this stage as well.
Avoid overmixing the batter. Too much mixing can develop the flour's gluten and leave the finished cake less tender.
Step 4: Bake the Cake
Pour the batter into the prepared pan and spread it evenly into the corners.
Bake for approximately 30–38 minutes, checking toward the earlier end of the range. The cake is ready when the center springs back lightly when touched and a toothpick inserted into the middle comes out clean or with a few moist crumbs.
If the toothpick comes out covered in wet batter, continue baking for a few minutes and check again.
Transfer the pan to a cooling rack and let the cake cool completely before frosting. Applying cream cheese frosting to a warm cake can cause it to melt and slide.
Step 5: Prepare the Cream Cheese Frosting
Place the softened cream cheese and butter in a mixing bowl. Beat until smooth and creamy, scraping down the sides of the bowl as needed.
Add the powdered sugar gradually, mixing on low speed at first to prevent it from puffing out of the bowl. Add the vanilla extract and a pinch of salt if desired.
Beat just until the frosting is smooth and spreadable. If it seems too soft, refrigerate it briefly before using.
Step 6: Frost the Cooled Cake
Once the cake has cooled completely, spread the cream cheese frosting evenly over the top.
For a simple finish, use the back of a spoon to create gentle swirls. If you like a little crunch, sprinkle chopped walnuts or pecans over the frosting.
Refrigerate the cake briefly if you want the frosting to firm up before slicing. Cut into squares and serve.
Tips for the Best Zucchini Cake
Measure the flour carefully. Too much flour can make the cake dense. For the most consistent results, weigh it if you have a kitchen scale, or spoon it into the measuring cup and level it off.
Don't over-squeeze the zucchini. A little natural moisture is helpful. Remove only excess liquid if the grated zucchini is unusually wet.
Use room-temperature ingredients. Eggs, butter, and cream cheese blend more smoothly when they're not refrigerator-cold.
Let the cake cool completely. This is especially important with cream cheese frosting, which softens easily when exposed to heat.
Don't overbeat the frosting. Once the ingredients are smooth, stop mixing. Excessive beating can make the frosting too soft to spread neatly.
Taste before adding extra sugar. The cake is already sweet, and the slight tang of the cream cheese helps balance the flavor.
Delicious Variations to Try
Zucchini Carrot Cake
Replace ½ cup of the grated zucchini with ½ cup finely grated carrot. The carrot adds natural sweetness and gives the cake a flavor reminiscent of classic carrot cake.
Chocolate Chip Zucchini Cake
Fold ½–¾ cup of semisweet chocolate chips into the batter. Chocolate pairs nicely with cinnamon and adds little pockets of sweetness.
Lemon Cream Cheese Frosting
Add 1–2 teaspoons of finely grated lemon zest to the frosting for a fresh citrus note. If adding lemon juice, use only a small amount to avoid making the frosting too loose.
Coconut Pecan Zucchini Cake
Add ½ cup shredded coconut and ½ cup chopped pecans to the batter. This combination gives the cake extra texture and a nutty, lightly tropical flavor.
Sheet Cake With Extra Spice
For a warmer flavor, increase the cinnamon slightly or add a small pinch of ground ginger. Keep stronger spices restrained so they complement rather than overpower the zucchini.
How to Store Cream Cheese Frosted Zucchini Cake
Because the frosting contains cream cheese, the finished cake should be refrigerated.
Refrigerator: Cover the cake or place individual slices in an airtight container and refrigerate for up to 4 days for best quality.
Before serving: Let slices sit at room temperature for about 10–20 minutes if you prefer a softer texture, keeping the total time out of refrigeration within safe limits.
Freezer: For best results, freeze the unfrosted cake tightly wrapped for up to 3 months. Thaw it in the refrigerator, then prepare and spread the frosting before serving. Frosted slices can also be frozen in a suitable airtight container, although the frosting texture may change slightly after thawing.
If you're making the cake ahead for a gathering, bake it the day before, let it cool, cover it, and refrigerate it. Frost it once cool, then keep it chilled until serving.
Frequently Asked Questions
Can you taste the zucchini in the cake?
The zucchini has a mild flavor that blends into the batter. The finished cake tastes primarily of vanilla, cinnamon, and brown sugar rather than vegetables.
Do I need to peel the zucchini?
No. The peel is thin and softens during baking. Leaving it on also saves preparation time. If you prefer a more uniform appearance, you can peel it first.
Should I squeeze the water out of the zucchini?
Usually, you don't need to squeeze out all the liquid. If the zucchini is particularly watery, gently remove some excess moisture so the batter doesn't become too wet.
Can I make this cake without nuts?
Absolutely. The walnuts and pecans are optional, so you can leave them out without changing the basic recipe.
Can I make the cake in advance?
Yes. You can bake the cake a day ahead and refrigerate it once cooled. You can also prepare the frosting separately and keep it covered in the refrigerator. Let the frosting soften slightly if needed, then spread it over the cake before serving.
Why did my cream cheese frosting turn runny?
The cream cheese or butter may have been too warm, or the frosting may have been overmixed. Refrigerate it briefly to help it firm up. Adding powdered sugar can thicken it, but too much may make the frosting overly sweet.
