What You’ll need to make Chocolate Zucchini Cake

Ingredients:

all purpose flour
unsweetened cocoa powder
baking soda
salt
sugar
zucchini
vegetable oil
vanilla extract
water
brewed coffee (cooled)
semi sweet chocolate chips

For the Ganache:

heavy cream
semi sweet chocolate baking bar

How to Make Chocolate Zucchini Cake

Start by preheating your oven to 350 degrees. Then grease a 10-cup bundt pan with non-stick cooking spray. You’ll want to make sure you grease the pan really well and get inside all the groves so the cake will release well after the cake has baked. Set your prepared pan aside.

In a large bowl, whisk the flour, cocoa powder, baking soda and salt. Set aside while you are preparing the wet ingredients.

Grate the zucchini over the large holes of a box grater.

In another bowl, using a spatula, mix the sugar, zucchini, oil, vanilla, water, and coffee just until combined.

Add the dry mixture and chocolate chips into the wet mixture and stir just until combined.

Pour the Chocolate Zucchini Cake batter into the prepared bundt pan.

Bake for 40-45 minutes, or until a toothpick comes out clean.

Cool in the pan for 10 minutes and then invert the cake onto a cooling rack to finish cooling. When the Chocolate Zucchini Cake is completely cooled, you’ll be ready to prepare the chocolate ganache.

Chop up the chocolate bar (1 cup) and add it to a heat proof bowl. Set aside.

In a saucepan, over low/medium heat, warm the cream just until simmering. Remove from the heat and pour the hot cream over the chocolate.

Allow the bowl sit for two minutes before mixing. Stir the chocolate and cream together until combined and chocolate is entirely melted.

Allow the ganache to sit for 5-10 minutes, just until it starts to thicken. Spoon the ganache over the Chocolate Zucchini Cake.

Let the ganache set on the cake for 30 minutes before cutting and serving.

Slice and serve! Cover the cake in an airtight container and store in the refrigerator for up to 4 days.

Frequently Asked Questions

What is the purpose of the brewed coffee in the cake?

Coffee, enhances the flavor of chocolate. If you don’t have brewed coffee, you can use instant coffee or espresso. If you prefer not to use any of these, you can leave them out, but you will need to substitute water for the coffee. It will still taste good, but will just not have the same depth of chocolate taste.

What is the best way to chop chocolate bars?

Using any knife will do a fine job of chopping chocolate, but using a serrated knife will cut down on static that can be a little messy. I like using a bread knife best!

Can I use frozen zucchini in this recipe?

Yes, but you will want to thaw it first and give it a gentle squeeze through a clean dishtowel to remove some of the liquid.

Why does Chocolate Zucchini Cake need to be refrigerated?

This will keep the ganache from separating and to avoid spoiling. Make sure the container is airtight! You want to enjoy every bite of this dreamy cake!
