Here’s my go-to zucchini carrot cake recipe, complete with a smooth cream cheese icing that’s impossible to mess up. The combination of fresh zucchini and sweet carrots creates a moist cake that’s topped with the perfect balance of tangy and sweet frosting.
This cake has become my kids’ favorite way to eat their vegetables without even realizing it. I often make an extra one for weekend gatherings, and there are never any leftovers. Because let’s be honest – who can resist a slice of homemade carrot cake with cream cheese frosting?

What Kind of Zucchini Should I Use?
For baking, medium-sized zucchini (about 6-8 inches long) are your best bet since they’re tender and have smaller seeds than the giant ones you might find in late summer. If you do end up with larger zucchini, just be sure to cut them lengthwise and scoop out the seedy center before grating. Fresh, firm zucchini will give you the best results – avoid any that feel soft or have wrinkled skin. Before grating, there’s no need to peel your zucchini unless you really want to, as the skin adds nice flecks of green to your cake and contains extra nutrients. A quick tip: after grating, give your zucchini a gentle squeeze to remove excess moisture, which helps prevent your cake from becoming too wet.
Options for Substitutions
This cake recipe is pretty adaptable and you’ve got several options for switching things up:
- Canola oil: You can easily swap canola oil with any neutral-flavored oil like vegetable oil, melted coconut oil, or even unsweetened applesauce (use 3/4 cup applesauce for a lower-fat version).
- All-purpose flour: Feel free to use just white or just whole wheat flour, or try gluten-free all-purpose flour blend (make sure it contains xanthan gum) – just note the texture might be slightly different.
- Zucchini and carrots: You can adjust the ratio of zucchini to carrots, or even use all carrots if that’s what you have. Just keep the total amount of grated vegetables the same (2.5 cups).
- Cream cheese: For the frosting, mascarpone cheese works great as a substitute. If you’re dairy-free, try dairy-free cream cheese alternatives – just make sure they’re at room temperature for smooth mixing.
- White sugar: You can use a mix of brown and white sugar (1 cup each) for a deeper flavor, or reduce the sugar to 1.5 cups if you prefer less sweetness. Just don’t cut it too much as it affects the cake’s texture.
- Icing sugar: This is pretty essential for the right frosting texture, but you can reduce it to 1.5 cups if you want a less sweet frosting. Just know it might be a bit softer.
Watch Out for These Mistakes While Baking
The biggest challenge when baking with zucchini is excess moisture – make sure to squeeze out as much liquid as possible from your grated zucchini using a clean kitchen towel or cheesecloth, otherwise your cake might end up too wet and dense.
Getting the right texture also depends on how you grate your vegetables – use the small holes of your grater for both zucchini and carrots, as larger shreds can make the cake heavy and affect how evenly it bakes.
When making the cream cheese frosting, temperature matters more than you might think – both the cream cheese and butter need to be at room temperature (but not too soft) to prevent lumps, and be careful not to overbeat the frosting as it can become too runny.
For the best results, let your cake cool completely before frosting, and if you notice the frosting getting too soft while working with it, pop it in the fridge for 10-15 minutes to firm up.
What to Serve With Zucchini Carrot Cake?
This moist and flavorful cake pairs perfectly with a hot cup of coffee or tea for an afternoon treat. Since it’s already rich with cream cheese frosting, keep things simple by serving it alongside a scoop of vanilla ice cream if you want to make it more dessert-like. For brunch gatherings, I like to serve this cake with some fresh berries on the side and a glass of cold milk. If you’re bringing this to a potluck or serving it at home, consider offering both regular and decaf coffee options since this cake works so well as an after-dinner dessert too.
Storage Instructions
Keep Fresh: Once your zucchini carrot cake is frosted, pop it in an airtight container and keep it in the fridge for up to 5 days. The cream cheese frosting needs to stay cool, but the cake actually gets even better after a day as the flavors have time to mingle!
Freeze: This cake freezes really well! You can freeze individual slices or the whole cake (unfrosted) for up to 3 months. Just wrap it tightly in plastic wrap and then aluminum foil. I suggest making the cream cheese frosting fresh when you’re ready to serve – it’ll taste much better that way.
Make Ahead: Want to prep this cake in advance? You can make the cake layers up to 2 days before you need them. Just wrap them well and store in the fridge. The frosting can be made a day ahead too – just let it soften a bit at room temperature before spreading.
