Best Easy Chocolate Zucchini Bread

Have you ever thought to turn zucchini bread chocolate? This is a seriously easy chocolate bread that is the best way to use up all the zucchini. It always seems like by the end of the summer we are up to our ears with zucchini – well, this choc zucchini bread is one of my favorite ways to use it.

Of course, zucchini is available all year so you don’t have to wait to try this recipe, but if it happens to be summer and you’ve got a bounty of this veggie in your fridge, easy chocolate zucchini bread is about to be your new best friend.

Why You’ll Love This Recipe

  • This is a quick bread: It’s a one-bowl chocolate zucchini bread recipe that is ready in no time at all. And it’s DOUBLE Chocolate Zucchini Bread!
  • It bakes up moist, soft, and loaded with chocolate. And, no, you can’t taste the shredded zucchini – it melts into the bread adding tons of moisture. You don’t have to worry about a dry quick bread with this one.
  • I love this recipe because it freezes great. Make a loaf and freeze the whole thing for later or slice it and freeze the individual pieces. They thaw in no time for an easy sweet treat when you get a chocolate craving.

Ingredients Needed

  • Vegetable oil: I prefer using a neutral oil in this quick bread.
  • Sugars: I like to use a combination of brown sugar and granulated sugar to keep the bread moist.
  • Unsweetened cocoa powder: Regular is best, not dutch process.
  • All-purpose flour: Be sure to measure flour correctly.
  • Shredded zucchini: Shred it yourself – there is no need to ring it out.
  • Chocolate chips: Use regular or mini chips! Or trade out the chips for chopped nuts, or use half and half.

Be sure to see the recipe card below for full ingredients & instructions!

Storing and Making Ahead

You can store this zucchini bread at room temperature or you can freeze it. It’s a great make-ahead bread and keeps well either way.

  • Room temperature: Once the bread is cool, wrap it in plastic wrap and it will keep at room temperature for three days.
  • Freezer: Or you can freeze the whole loaf or individually wrapped slices for up to three months.

Why did my quick bread fall after baking?

There could be a few reasons why your bread collapsed:

  • Did you measure the ingredients correctly? Too much liquid in the batter can cause the bread to sink in the middle when it cools.
  • Don’t let the batter sit around too long before baking it. As soon as you’ve made it, it’s best to get that loaf into the oven. If the batter sits too long, the leavening agents lose their effectiveness.
  • Did you bake it long enough? If you take the chocolate zucchini bread out of the oven too soon the center will not be done, causing the loaf to sink. So, always do the toothpick test – once it comes out with just a few crumbs, it’s done. If there is batter on it, leave the bread in the oven.

How do you know zucchini bread is done?

You know the zucchini bread is done once you insert a toothpick in the center of the bread and it comes out with just a few moist crumbs.

What cocoa is best for zucchini bread?

The best cocoa for this recipe is unsweetened cocoa powder. I haven’t tested it with Dutch-process cocoa powder.

How do you shred zucchini?

You can shred it with a box grater or in a food processor fitted with a grating disc attachment.

Why is my chocolate zucchini bread flat?

The culprit may be your baking soda and/or baking powder if it’s expired so check the expiration date. If either are expired your bread won’t rise properly as it bakes. It could also be the way you mixed the batter. If you mix the batter too hard and fast, air bubbles get trapped in it. When the bread bakes those air pockets pop causing your bread to collapse. To avoid this, don’t use a mixer at high speed or, better yet, mix the batter with a spoon or spatula. It could also be the pan – I like to use an 8×4” loaf pan for this recipe because the bread gets a nice dome. You can use a 9×5” loaf pan, but the bread will have a flatter top.

Can you make muffins with this recipe?

Yes it will make approximately 12 muffins. Bake time approximately 15-20 minutes.

  1. Very good! Chocolatey goodness. Added cherries and pecans and used non-gluten flour. All worked well and I will make it again!
