Moist Carrot Zucchini Cake with Cream Cheese Frosting

This moist carrot zucchini cake with cream cheese frosting quickly became my favorite way to sneak extra veggies into dessert. I wanted a cake that was tender, flavorful, and rich without being dry, and my first attempts taught me a few important lessons. Skipping the draining step for zucchini made the batter too wet, and under-spicing the mixture left it tasting bland. After adjusting the moisture, spices, and frosting, this cake turned out perfectly soft, flavorful, and decadent.

It’s great for birthdays, tea time, or any occasion when you want a comforting slice that still feels wholesome.

Ingredients

Dry Ingredients

• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• ½ teaspoon salt
• 1 teaspoon ground cinnamon
• ½ teaspoon ground nutmeg
• ½ teaspoon ground ginger (optional)

Wet Ingredients

• 1 cup grated zucchini, well-drained
• 1 cup grated carrots
• ¾ cup vegetable oil or melted coconut oil
• 1 cup granulated sugar
• ½ cup brown sugar, packed
• 4 large eggs
• 1 teaspoon vanilla extract

Optional Add-Ins

• ½ cup chopped walnuts or pecans
• ½ cup raisins or shredded coconut
• ½ cup crushed pineapple, well-drained

Cream Cheese Frosting

• 8 oz cream cheese, softened
• ½ cup unsalted butter, softened
• 2 cups powdered sugar
• 1 teaspoon vanilla extract

Preparing the Zucchini and Carrots

Grate and Drain

• Grate zucchini and carrots using the medium holes of a box grater
• Place zucchini in a clean kitchen towel and squeeze out excess moisture
• Lightly press carrots if very juicy

Draining the zucchini is crucial for preventing a dense, soggy cake.

Mixing the Cake Batter

Combine Dry Ingredients

• In a medium bowl, whisk together flour, baking soda, baking powder, salt, cinnamon, nutmeg, and ginger

Combine Wet Ingredients

• In a large bowl, whisk sugar, brown sugar, and oil
• Add eggs one at a time, mixing well after each
• Stir in vanilla, grated zucchini, and carrots

Bring Together

• Gradually fold dry ingredients into the wet mixture
• Mix gently until just combined
• Fold in optional add-ins like nuts, raisins, or pineapple

Overmixing can make the cake dense, so fold gently.

Baking Instructions

Prepare the Pan

• Preheat oven to 350°F (175°C)
• Grease and flour two 8-inch round cake pans or a 9×13-inch pan
• Line with parchment paper if desired

Bake the Cake

• Divide batter evenly into pans
• Bake for 35–45 minutes (less for cupcakes), until a toothpick comes out clean
• Let cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely

Preparing the Cream Cheese Frosting

Make the Frosting

• In a large bowl, beat cream cheese and butter until smooth
• Gradually add powdered sugar and beat until creamy
• Stir in vanilla extract

Adjust consistency by adding more powdered sugar for a thicker frosting or a teaspoon of milk for a softer spread.

Assembling the Cake

• Spread a layer of frosting on the bottom layer of cake (if using two layers)
• Place the second cake layer on top and frost the top and sides
• Decorate with chopped nuts, carrot curls, or a sprinkle of cinnamon if desired

Preparation and Cooking Time

• Prep time: 25 minutes
• Cook time: 35–45 minutes
• Total time: About 1 hour 15 minutes
• Servings: 12–14 slices
