Ingredients for Decadent Zucchini Cake Bars

For the Cake:

• 2 cups all-purpose flour (swap with almond flour for gluten-free)
• 1 teaspoon baking powder
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 teaspoon ground cinnamon
• 1/2 teaspoon ground nutmeg
• 1 cup granulated sugar
• 1/2 cup light brown sugar, packed
• 1 cup vegetable oil (or melted coconut oil for a hint of tropical flavor)
• 3 large eggs
• 2 teaspoons vanilla extract
• 2 cups grated zucchini (lightly squeezed to remove excess moisture)
• 1/2 cup crushed pineapple, drained
• 1 cup chopped walnuts (optional)

For the Cream Cheese Frosting:

• 8 oz cream cheese, softened
• 1/2 cup unsalted butter, softened
• 4 cups powdered sugar
• 2 teaspoons vanilla extract
• 1–2 tablespoons milk (as needed for consistency)

How to Make Zucchini Cake Bars – Step by Step

Step 1 – Prep Your Pan & Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking pan or line it with parchment paper for easy removal.

Step 2 – Combine Dry Ingredients

In a medium bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, and nutmeg until well combined.

Step 3 – Mix Wet Ingredients

In a large mixing bowl, beat granulated sugar, brown sugar, and oil until smooth. Add eggs one at a time, mixing well after each. Stir in vanilla extract.

Step 4 – Bring it All Together

Gradually add the dry mixture to the wet mixture. Stir until just combined—don’t overmix. Gently fold in zucchini, pineapple, and walnuts (if using).

Step 5 – Bake to Perfection

Spread the batter evenly in your prepared pan. Bake for 28–32 minutes or until a toothpick inserted into the center comes out clean.

Step 6 – Make the Frosting

In a large bowl, beat cream cheese and butter until fluffy. Gradually add powdered sugar on low speed until incorporated. Stir in vanilla. Add milk, 1 tablespoon at a time, until desired consistency is reached.

Step 7 – Frost & Serve

Once the cake is completely cooled, spread frosting evenly over the top. Slice into bars and serve.

Pro Tips for Making the Best Zucchini Cake

• Drain your zucchini well – Too much moisture can make the cake soggy.
• Don’t skip the pineapple – It adds natural sweetness and moisture.

• Chill before slicing – For cleaner edges and easier serving.

Best Ways to Serve Zucchini Cake Bars

• With coffee or tea – Perfect for afternoon treats.
• As a holiday dessert – Garnish with candied walnuts or a sprinkle of cinnamon.
