Zucchini Chocolate Cake

Make this cake when you're long on zucchini, or just want to hide some nutritious vegetables into your baking! The whole grain flour creates a soft flavourful crumb and the choice of milk or dark chocolate us up to you! 

Zucchini Chocolate Cake
1/2 cup (115g) softened, unsalted butter
1/2 cup (132g) vegetable oil
1 & 3/4 (370g) cups granulated sugar
2 tsp vanilla extract
1 tsp baking powder
1/2 tsp baking soda
1/2 tsp salt
2 large eggs
1/2 cup full fat greek yogurt
2 & 1/2 cups (352g) Flourist Organic Whole Grain Red Fife Flour
3/4 cup unsweetened natural cocoa powder
3 cups shredded zucchini
1/2 (75g) cup milk or dark chocolate chunks

1 & 1/3 cups (200g) milk or dark chocolate chunks
7 tbsp whole milk
1/2 cup icing sugar

First, preheat the oven to 350 degrees, and grease and line a 9x13" baking pan with parchment paper.

In a large mixing bowl, beat together the butter, oil, sugar, vanilla, baking soda, baking powder and salt until smooth. Next, beat in the eggs until just combined. Stir in the yogurt, flour, and cocoa powder and mix together until just combined. Lastly, gently fold in the zucchini and chocolate chunks.

Pour the batter into the pan, smoothing it out to ensure it is level. Bake for 40-45 minutes, or until a toothpick comes out clean. Allow to fully cool before frosting! 

For the frosting combine the chocolate chunks and milk in a saucepan over medium heat and stir until fully combined. Gently fold in the icing sugar until smooth. Pour over cake entirely, and allow it to set to before slicing! 

If you are local, try this with our favourite butter, eggs and our cocoa powder.

Hello @Lou! Thank you for asking! We’ve updated the post to include the chocolate weights. Happy Baking!

How many grams of chocolate for both the cake and frosting instead of cup measure?

Shira @ Flourist

Hi Amanda and Veronika! Oh no! Soooo sorry we missed adding the cocoa powder to the instructions AND the baking powder too! We’ve thoroughly reviewed the post again and updated the instructions. Our apologies, whoops! This recipe needed a much more thorough review before posting.

Thank you for the notes, please let us know how the cakes turned out! xx


What happened to the cocoa powder? The directions do not include when to add the cocoa powderI followed the direction forgetting the cocoa powder. Also omitted from the directions baking powder.
I will let you know how it is


Hi friends!! Just made this and when I put it in the oven I realized I hadn’t put any cocoa in. What stage was it meant to be added?
