Chocolate Zucchini Bread

You are going to love how indulgent tasting this chocolate zucchini bread is — and especially when considering all the great nutrient-filled ingredients we’re loading into this bread. While there is still a good amount of sugar, there is a fraction of the sugar that other recipes contain. We’re also using tons of other healthier ingredient swaps — dark cocoa powder and dark chocolate chips (healthy fats and antioxidants –yeah!), protein-packed Greek yogurt, oats in place of some of the flour, coconut oil, and — of course– let’s not forget we’re adding veggies to this bread in the form of zucchini!  

Check out the next section for some helpful ingredient notes and suggestions before heading to the grocery store! 🙂

Chocolate Zucchini Bread Ingredient Notes

  • Special Dark® Cocoa Powder contributes the deep and intense chocolate flavor in this chocolate zucchini bread. I highly recommend using a Dutch-process cocoa powder as opposed to a plain (natural) cocoa powder. Hershey’s Special Dark cocoa powder is readily available at most grocery stores.
  • Honey Vanilla Greek Yogurt adds protein, moistness, and tons of flavor to this bread. Our favorite yogurt to use is Honey Vanilla Greek yogurt (made by Greek Gods®). I don’t recommend a low fat or non-Greek yogurt in this bread, it won’t turn out the same. While plain Greek yogurt works, the flavored yogurt adds so much additional flavor to this chocolate zucchini bread without extra ingredients.
  • Chocolate Chips. Any type of chocolate chip will work — semi-sweet, milk, dark, or chopped up chocolate. We typically use dark chocolate to keep this bread on the more nutritious side.
  • Coconut oil. Make sure to get the measurement with the oil melted (not in the hardened state). Allow ample time for the coconut oil & chocolate mixture to cool down so it’s not hot when added to the other wet ingredients. It it’s added in hot, it will cause the ingredients to seize up.
  • Zucchini. For this bread, we use zucchini that has been grated on the small side of the grater for fine zucchini shreds. No need to peel the zucchini first or squeeze out excess moisture — we rely on that added moisture in this bread. I don’t recommend grating zucchini on the large holes of a grater for this particular recipe.

What is oat flour?

Basically just powdered (blended) oats. It adds a great texture, a unique flavor, and a nutritious aspect to Chocolate Zucchini Bread. No need to go buy oat flour; oats blend up in seconds.

How to make oat flour in 30 seconds or less: All you do is blend up regular old fashioned (or quick oats) in a blender until the resemble regular flour. I’ve used $20 blenders and my high powered Blendtec and both will do the trick just fine. 

QUICK TIP

Unfortunately you can not use ALL oat flour in this bread. I have tried it and it was not successful. Also if you attempt to use a different flour in this chocolate zucchini bread please note that it may not yield the right texture. Oat flour absorbs much more liquid than regular flour.

Baking Tips

  • Don’t over mix. If you over-mix the batter, you’ll end up with a denser loaf. Mix until ingredients are just combined and then pop it in the bread pan and bake! 
  • Generously grease bread pan.  I like to grease the bread pan with nonstick spray and then lightly dust with flour. There are few things as frustrating as trying to invert a loaf and having it fall apart or stick to the bottom. Take your time to generously grease the pan or line it with parchment paper leaving an overhang for easy bread removal.
  • Cool baked bread on a wire rack. Run a table knife along the edge of the pan and invert the loaf onto the wire rack. Chocolate Zucchini Bread needs to be elevated so air can circulate around all sides as it cools. Otherwise, moisture (from the heat of the bread) will condense on the bottom of the bread, making it damp and slightly sticky.
  • Use the right size pan. We use an 8.5 x 4.5-inch bread pan for this recipe; it doesn’t bake up the same in other sized pans.

How To Know When Chocolate Zucchini Bread Is Done

It can be tricky to know when quick breads are baked fully. There is a lot of variances in baking zucchini bread such as altitude, humidity, actual oven temperature, bread pan used, etc. Here are a few cues to look for and tips to keep in mind:

  • Preventing under-baked zucchini bread: Make sure your oven is correctly calibrated; wait for the oven to fully preheat before adding the bread to the oven and position the loaf in the center of the oven.
  • Visual cues for doneness: Bread has pulled away from the edges of the pan slightly 
  • Physical cue for doneness: A toothpick (or fork) inserted into the center of the chocolate zucchini bread comes out clean or with a couple of moist (not wet) crumbs.

Storage

This bread stores 1-2 days at normal room temperature (wrapped tightly/stored in an airtight container).
 
After 3-4 days, this bread is more prone to molding because of the ingredients used and the overall moistness of the bread. Warm refrigerated (unwrapped) slices in the microwave for 5-10 seconds. Freeze any leftover slices for up to 3 months (individually wrapped and then in another zip-top bag). To thaw, set out wrapped slices at room temperature for about an hour.
 
Warm leftover slices in the microwave for 5-10 seconds before enjoying. Add a slather of peanut butter for a fun flavor variation!

Ingredients

  • 1/2 cup (113g) honey vanilla Greek yogurt (we love Greek Gods)
  • 2 tablespoons (50g) honey
  • 1/2 cup (100g) light brown sugar, lightly packed
  • 1/3 + 3/4 cup dark chocolate chips, divided
  • 1/3 cup (65g) melted coconut oil
  • 1 and 1/2 teaspoons vanilla extract
  • 1 large egg
  • 1/3 cup (32g) oat flour (just blend regular oats in a blender -- Note 1)
  • 2 tablespoons (9g) Special Dark (dutch process) cocoa powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon baking powder
  • 1/2 teaspoon fine sea salt
  • 1 cup (133g) white flour (or use white-whole wheat)
  • Heaping 3/4 cup (103g) lightly packed and finely grated zucchini
  • 1 tablespoon (7g) cornstarch

Instructions

  • PREP: Preheat the oven to 350 degrees F (176 degreed C). Lightly grease and flour an 8 and 1/2 by 4 and 1/2 inch pan OR line with parchment paper leaving an overhang for easy removal. Grate zucchini on the SMALL holes of a grater. Measure and set aside.
  • WET INGREDIENTS: In a medium-sized bowl, stir together the Greek yogurt, honey, and brown sugar until smooth.
  • CHOCOLATE & COCONUT OIL: In another small microwave-safe bowl place 1/3 cup (62g) chocolate chips. Melt the coconut oil and measure the oil AFTER being melted. Pour the melted coconut oil over the chocolate chips and stir. Microwave in bursts of 15 seconds, stirring for 20 seconds in between each burst until chocolate is fully melted and smooth. Allow to cool to room temperature and then use a spatula to scrape every bit into the Greek yogurt mixture. Stir to combine. Add in the egg and vanilla extract and stir until smooth.
  • DRY INGREDIENTS: In a separate bowl, stir together the oat flour (Note 1), cocoa powder, baking soda, baking powder, salt, and cornstarch. Add in the white or white-whole wheat flour. Add in the remaining 3/4 cup chocolate chips (118g). Stir the dry ingredients together.
  • COMBINE: Add the dry to the wet. Add in the zucchini. Gently stir until just combined. Over-mixing will result in dense bread or a sunk in center.
  • BAKE: Use a spatula to scrape every bit of the mixture into the prepared pan and smooth the top into an even layer. Top with a few more chocolate chips if desired. Bake for 45-55 minutes or until a toothpick when inserted into the center comes out with dry or moist (NOT wet) crumbs. The bread should also slightly be pulling away from the sides. Be careful to not over-bake, it will yield a much drier, less tasty zucchini bread.
  • ENJOY: Remove from the oven and let cool for 10 minutes before inverting it on to a cooling rack to finish cooling. Allow to completely cool before cutting into the bread -- otherwise it's pretty crumbly! Cut with a very sharp, serrated knife. Best enjoyed the same day -- see "Storage" notes below.

Recipe Notes

Note 1: I use regular old fashioned or quick oats and quickly pulse them in a blender or food processor until they resemble flour. Then measure and add to the bowl (the measurement should be taken after the oats are blended, not before).

    1. Thank you so much Olivia! 🙂 Yes the grey back board is an Erickson concrete board! It’s a custom (in between dark and light concrete). 🙂

  1. 5 stars
    Sounds new.I used to prepare bread recipe during weekends,Sounds like this recipe is gonna be my surprise for my family.Thanks for sharing a great recipe.

  2. 4 stars
    Just tried this recipe. I was a bit confused because I couldn’t find a reference to the rest of the white/whole wheat flour or cocoa powder in the directions (not a baker!). So, I did add the flour but forgot the cocoa powder. I’m sure it will be tasty but I do need those extra steps in the recipe. I think more experienced bakers just know when to add. Or did I miss it completely? In the oven now & it looks great!

    1. I’m so sorry Leslie, I updated the recipe to hopefully make the steps more clear. I hope you loved the bread! 🙂

    1. I apologize for any confusion! I’ve updated the recipe to hopefully make more sense. You add in the flour 🙂

  3. 5 stars
    I have made this recipe three times now and we LOVE it. My picky five year old son devours it and it never lasts more than a few hours. Thank you!

    1. You are welcome! I’m so happy this is a hit! Thank you so much for the comment and review 🙂

    1. I’ve never tried this recipe in muffin tins and I’m not sure how it would work. If you do try it though, I’d avoid liners (just grease and flour the cavities!)

  4. Hi I plan to make this but I don’t see any nutritional facts where can I find those? And do you know what the exchanges are for this if using an exchange diet?

    1. I don’t have nutrition facts on all of my recipes (yet!) so I’d recommend using My Fitness Pal in the meantime 🙂

  5. 5 stars
    Just made this. Many ingredients and steps but well worth it! Used dark chocolate chips. Moist and chocolatey…delish!
