Ingredient notes

SO MUCH Chocolate: Chocolate chips, melted semi-sweet chocolate, and dutch processed cocoa powder make this a ‘triple chocolate zucchini bread.

Zucchini: Zucchini makes the bread extremely moist and tender, with the added benefit of some health benefits!

Oil: Oil is used in this recipe, instead of butter, as it makes the loaf more fudgy and moist.

Instant Coffee: The small amount of instant coffee really amplifies the chocolate flavour.

How to make triple chocolate zucchini bread

1. Melt Chocolate: Add chopped chocolate to a microwave safe bowl, then place into the microwave, and microwave in 30 second intervals, stirring in between, until melted. Pour in the oil, then whisk to combine.

2. Combine wet ingredients: Add the eggs and vanilla, to the bowl with the melted chocolate and oil, then whisk together until smooth and well-combined.

3. Whisk together the dry ingredients: In a separate mixing bowl, add the flour, sugar, sifted cocoa, baking powder, baking soda, salt, and instant coffee.

4. Add the dry & wet together: Pour the dry mixture into the wet mixture, and whisk together until mostly smooth.

5. Fold in chocolate chips and zucchini: Add the chocolate chips and shredded zucchini to the batter, then lightly fold them in until fully dispersed and well combined.

6. Add to pan & bake: Pour the chocolate quick bread batter into a prepared 9×5” pan, top with additional chocolate chips, then place into the oven to bake!

Tips & tricks

Use Dutch processed cocoa powder: Dutch cocoa is less acidic and tastes more rich and chocolatey in flavour. Here is a link to my favorite brand.

Use quality chocolate chips and quality melted chocolate: You’ll just want to make sure they are both real chocolate!

Use room temperature ingredients: Using room temperature ingredients means that the zucchini chocolate chip bread can bake more evenly, meaning you’ll get a softer, fluffier chocolate loaf cake.

Don’t overbake: Overbaking will dry the bread out! Be sure to check the bread at 60 minutes (or even earlier if you know your oven runs hot).

Weigh your ingredients: Weighing the ingredients will yield the best and most consistent results. Volumetric measurement can be off by significant amounts, leading to inconsistent baking.

Equipment required

9×5” loaf pan: Here is one I love – its non-stick and it is lighter in color, meaning it bakes more evenly!

Microwave: A microwave makes melting the chocolate easier – however, you can also melt it over a bain-marie, too.

Box Grater: I love this one – it’s nice and sharp and gets the job done quickly and easily.

How to store the zucchini chocolate chip bread

Room Temperature: The fully cooled zucchini bread can be kept at room temperature in an airtight container for 4-5 days.

Fridge: The bread can also be stored in the fridge, in an airtight container, for up to a week.

Freezer: The bread can wrapped in plastic wrap, then placed into a freezer bag to be frozen for up to 3 months. The loaf can be frozen as a whole, or sliced up.

FAQ

How should I prepare my zucchini for the bread? 

No need to peel the zucchini, just grate it with your typical box grater, then fold into the batter.

Do I need to squeeze the water out from my zucchini?

No, the moisture from the zucchini helps add moisture to the chocolate zucchini bread.

Can I freeze the loaf?

Yes, this bread freezes extremely well – see storage instructions above!

Can I use regular cocoa powder?

Yes, regular cocoa powder can be used.

Can I use chopped chocolate instead of chocolate chips?

I wouldn’t recommend it, as regular chocolate melts more than chocolate chips, so the chocolate will melt into the loaf too much.

How do I store this zucchini chocolate chip bread?

See storage instructions above!

My bread is dry, why?

The biggest culprit is either overbaking, improper measurement (typically too much flour), or that you squeezed out moisture from the zucchini.

My zucchini bread didn’t rise?

Your baking powder has most likely gone bad!

How long will this zucchini loaf last in the fridge?

It’ll last 1 week if stored in an airtight container in the fridge, or 4-5 days on the counter at room temperature.
