What Is A Chocolate Zucchini Bread?

The idea of putting zucchini in a cake is not new, I have several other recipes with zucchinis like my Almond Flour Zucchini Bread.

But this recipe combines the moist zucchini with chocolate for a delicious low-carb bread loaf.

How To Make Keto Chocolate Zucchini Bread

If you love thick, moist chocolate bread, this paleo chocolate zucchini bread will make you so happy.


All you need to make a delicious paleo chocolate zucchini bread are:

  • Grated zucchini – make sure you pack the zucchini very well into the measuring cup for precise measurement. If some liquid is released from the grated zucchini, discard it or the bread will be too moist and won’t hold as well. Zucchinis are great keto-friendly vegetables with less than 2g of net carbs per 100g!
  • Egg – I used large eggs. Eggs are 100% keto-friendly.
  • Coconut oil – if you don’t like the flavor of coconut oil, use refined coconut oil. It does not have a coconut flavor. I won’t recommend a different oil for this bread.
  • Canned coconut cream – or cream of your choice.
  • Sugar-free crystal sweeteners  – Monk fruit crystal is my favorite option. To learn more about keto-friendly sweeteners or to convert them, try my sweetener converter.
  • Almond flour– the finer, the better. Learn how to pick your keto flour.
  • Baking soda
  • Vanilla extract
  • Chopped walnuts – or chopped pecan or omit if you don’t like nuts in your bread.
  • Sugar-free chocolate chips – store-bought or your homemade sugar-free chocolate chips.
  • Unsweetened cocoa powder or unsweetened cacao powder for a stronger chocolate flavor.
  • Cinnamon

Start by grating the zucchini with a hand grater or the grater attachment of a food processor.

Place the grated zucchini in a kitchen towel and squeeze it hard to extract as much water as possible from the zucchinis.

Combine all the dry Keto Chocolate Zucchini Bread ingredients in a large mixing bowl.

Add the grated zucchini and all the liquid ingredients and whisk them with a silicone spatula until they form a thick batter.

Incorporate the chopped nuts and sugar-free chocolate chips.

Transfer the Keto Chocolate Zucchini Bread batter into a 9-inch x 5-inch loaf pan lined with lightly oiled parchment paper. Keep some overhang of parchment paper to make it easier to unmold the bread.

Bake your zucchini bread for 50 to 55 minutes in an oven preheated to 350°F (180°C).

You know it’s cooked when a skewer inserted in the middle comes out relatively free of crumbs.

This paleo chocolate zucchini loaf is ultra moist due to its large amount of zucchini. My trick, cool it down to room temperature, then pop it in the fridge for one hour to firm up.

Trust me; you won’t regret it! The bread is much easier to slice, as well as it firms up in the fridge creating the most delicious fudgy chocolate texture!

It is very important to be patient with this bread.

I recommend cooling it down for 10 minutes in the loaf pan, then 40 minutes on a cooling rack, and finally popping it in the fridge for 1 hour for the best result.

Of course, it is up to you, but I notice that the cooler it is, the fudgier it becomes. Plus, it is much easier to slice!

Chocolate Decoration

I decorated the top of my bread with a good amount of sugar-free chocolate chips. I always add them after I transfer the chocolate zucchini bread to my cooling rack.

The bread is still hot, and the chocolate chips melt on top.

If you intend to cool down in the fridge as recommended before the chips will harden, it makes the cutting much more difficult with the hard chocolate shell on top of the moist bread, so be aware of that, and choose what is right for you!

Store the keto chocolate zucchini bread in the fridge for up to 4 days in a cake box or airtight container.

You can also freeze slices in individual zip-lock bags for up to 3 months.

Frequently Asked Questions

Can I Use An Egg Replacer?

No, egg replacers or flaxseed eggs wouldn’t work in this recipe. You have to use an egg.

Can I Use Swerve As A Sweetener?

Yes, Swerve is essentially just erythritol so it’s a perfectly fine option.

Can I Swap The Baking Soda?

Yes, you can replace the baking soda with twice the amount of baking powder.

Dry ingredients

Wet ingredients

Filling – optional


  • Preheat oven to 350°F (180°C). Line a baking loaf pan (9 inches x 5 inches) with parchment paper. Set aside.
  • Remove both extremities of the zucchinis, keep their skin on. 
  • Finely grate the zucchini using a vegetable grater. Measure the amount needed in a measurement cup. Make sure you press/pack them firmly for a precise measure and to squeeze out any liquid from the grated zucchini. I usually don't have much! If you do, discard the liquid or keep it for another recipe.
  • In a large mixing bowl, stir all the dry ingredients: almond flour, unsweetened cocoa powder, sugar-free crystal sweetener, cinnamon, sea salt, and baking soda. Set aside.
  • Add all the wet ingredients into the dry ingredients: grated zucchini, coconut oil, coconut cream, vanilla, egg, and apple cider vinegar.
  • Stir to combine all the ingredients. 
  • Stir in the chopped nuts and sugar-free chocolate chips. 
  • Transfer the chocolate bread batter into the prepared loaf pan.
  • Bake for 50 – 55 minutes. You may want to cover the bread loaf with a piece of foil after 40 minutes to prevent the top from darkening too much, up to you.
  • The bread will stay slightly moist in the middle and firm up after fully cool down.

Cool down

  • Cool down for 10 minutes in the loaf pan, then cool down on a cooling rack until it reaches room temperature. It can take 4 hours as it's a thick bread. Don't slice the bread before it has cooled down. If too hot in the center, it would be too soft and would fall apart when you slice. For a faster result, cool down 40 minutes at room temperature then pop in the fridge for 1 hour. The fridge will create an extra fudgy texture and the bread will be even easier to slice as it firms up.
  • Store in the fridge up to 4 days in a cake box or airtight container.

    89 Thoughts On Keto Chocolate Zucchini Bread

  1. Hi. I tried this recipe. I use 3 small loaf tines instead of the large one, and did have coconut cream so subbed in full fat Greek yogurt. My loaves fell in the centre. Any idea as to why? Thanks. Looking forward to tasting after they cool, but not pretty to give as a hostess gift.

    • I thick the yogurt or the small pan can impact the baking of the recipe .It can be the reason why they deflated or you did remove the loaf form a hot oven to a cool place which makes baked goods deflate faster.

  2. 5 stars
    I just found you recently, and this is the 3rd recipe Ive made with great success! Your Lemon Pound, the Marble, and now this Chocolate Zucchini cake. I did finally get brave enough to bake in an 8×4 vs. the often recommended 9×5. These desserts don’t rise much, and I love a higher cake, it still came out perfect. So moist, very fudgey!. I chopped up a half of a Lily’s Chocolate bar, and added sprouted & dehydrated pecans. Everything has been delicious, and appreciated by others as well. I am excited to try more things. Thank you! you are legit!

  3. This was delicious.I was hesitant about the small amount of coconut oil but it was perfectly sweet and moist Great recipe.Thank you for all your hard work developing these recipes

  4. The chocolate and nuts are optional. We’re they used when calculating the nutritional informational is that without them?

  5. Can I use Swerve or stevia as a sweetener in this recipe? I can’t find straight erythritol where I live.

  6. I made a double batch(to many zucs), one as a loaf and the rest as muffin. The recipe clearly promotes to refrigerate for the moist center but the photos have the melted chips which of course looks great.
    What is your preference and is it the same for both variation?

  7. 4 stars
    Followed the recipe almost exactly and they turned out great except had an overwhelmingly strong taste of baking soda that made them unpalatable. I’ll try to use less next time, starting with 1 tsp – do you have any suggestions? Cooked in silicon egg bite molds for 24 mins, so they would be snack size for my first grader. Just had to cut them in half and smear them with keto frosting so she’d eat them. Couldn’t taste the zucchini and they were moist enough. Also used a tiny bit less sweetener like I normally do for baked goods, but this definitely needed at least the full amount.

  8. 5 stars
    Made a doz cupcakes out of this recipe. Very good, will make this again. Substituted with heavy cream in place of coconut cream and butter in place of coconut oil.

  9. 5 stars
    Thanks for all the Zucchini recipes. I have 5 x Two foot long ones in the garden and it will be wonderful doing all these !!

  10. 5 stars
    This is FANTASTIC! By far the best Keto dessert I have made to date! Bravo!!! Followed the recipe exactly, except I added 1/4 c. more chocolate chips, then instead of using a bread pan I made muffins. Absolutely delicious! Thank you SO Much!

    • Absolutely! I usually cool down the bread overnight, slice the next day and freeze each slice in individual container or bags to make it easier to defrost one serve at a time. Enjoy, XOXO Carine

    • Sure, Xylitol is fine in cakes but not really in my cookies recipes, it make the cookies very soft. Enjoy the recipe, XOXO Carine

    I fondly renamed to this to Brownie Bread. I’ve also made this several times and have made my share of mistakes (putting my wet ingredients in with my dry not paying attention, misreading my new measuring spoons (they’re weird) adding way more baking soda and salt than called for etc….sheesh!) The one thing I don’t do is measure out the zucchini and I don’t squeeze out any excess moisture (I use 2 small or 1 large). The batter should look exactly like the batter in the video – if it appears too dry, try adding some more zucchini and/or a couple more TBS of the coconut cream – it’ll straighten the batter out like snapping your fingers- which is exactly what I did when I made all those huge mistakes…LOL!! Nobody knew the difference. As a rule I mix all my wet ingredients together including the zucchini – mix all my dry ingredients together and combine the two, adding the chocolate chips and nuts last. I always use parchment and only bake in a metal loaf/bread pan. Comes out perfect every time!!

    • It helps activate the raising agent ans raise the bread more. You can replace this by lemon juice too. Enjoy, XOXO Carine

  12. I haven’t got a website
    I just purchased the Keto program in order to get started and I am exploring… I came across a Delicious Key lime pie or cheesecake??? And the person showing gave your blog site…. so Here I am. I’ve already purchased over $ 300 in cookbooks and programs, plans etc and for the moment don’t want to invest more $$$ just explore…. before I jump in

    • Hello! Welcome here:) I am so glad you like the blog recipes here. If you have any questons, just comment here, I am happy to help you and support you through your keto lose weight journey. XOXO Carine
