Instructions

Step 1: Prepare the Pan

Preheat oven to 350°F (175°C).

Grease and flour a 9×13-inch baking pan.

Set aside.

Step 2: Mix Dry Ingredients

In a large bowl whisk together:

• Flour
• Cocoa powder
• Baking soda
• Baking powder
• Salt
• Cinnamon (if using)

Set aside.

Step 3: Mix Wet Ingredients

In another large bowl whisk together:

• Vegetable oil
• Sugar

until combined.

Add:

• Eggs
• Vanilla extract

Whisk until smooth.

Step 4: Add the Zucchini

Fold the shredded zucchini into the wet ingredients.

Do not squeeze out the moisture.

The zucchini helps keep the cake incredibly soft.

Step 5: Combine the Batter

Gradually add the dry ingredients to the wet ingredients.

Mix just until combined.

Fold in:

• Chocolate chips

The batter will be thick.

Step 6: Bake

Spread the batter evenly into the prepared pan.

Bake for 35–40 minutes.

The cake is done when:

• A toothpick inserted in the center comes out with a few moist crumbs
• The top springs back when touched

Allow the cake to cool completely.

Add:

• Powdered sugar

alternating with the milk.

Mix until smooth.

Add:

Beat for 2–3 minutes until fluffy.

Tips for Success

Don’t Peel the Zucchini

Avoid Overmixing

Mix only until the ingredients are combined.
