My Blueberry Zucchini Bread Is Super Moist, Lemony, And Secretly Healthier
This blueberry zucchini bread is my bright, summery twist on classic zucchini bread, but made with juicy berries, fresh lemon, and a soft crumb that reminds me of coffee cake. I originally published this recipe in 2017, and it’s gone through a few minor revisions over the years, as I keep improving upon it almost every summer. Here’s why this year’s updated version is my best yet:
- Super moist, but easier to slice – I’ve always made this blueberry zucchini bread with almond flour for a moist, delicate crumb, but this year I also added a little coconut flour after some readers found the loaf too wet. It absorbs just enough liquid to help the slices hold together, but still keeps my favorite part: the super moist texture. In fact, I debated adding more because it’s still quite delicate, but decided it’s better this way because that’s what makes it taste so good — even if it falls apart a little!
- Bright blueberry-lemon flavor – Every slice has sweet bursts of fresh blueberries, fresh lemon, and an optional-but-highly-recommend-it tangy glaze.
- Secretly healthier – My blueberry zucchini bread recipe is naturally gluten free (no white flour), has no refined sugar, and even packs in a little protein and fiber.
- Easy one-bowl batter – The batter takes about 15 minutes to prepare, and the rest is hands-off.
Compared to the more common versions, this blueberry zucchini bread is a little lighter, a whole lot brighter, and in the heat of summer, it’s my absolute fave. I love a slice with my morning protein coffee, but it’s just as good for an afternoon snack or even as a healthy dessert. Make it with me!

Ingredients & Substitutions
Here I explain the best ingredients for my blueberry zucchini bread recipe, what each one does, and substitution options. For measurements, see the recipe card.
- Zucchini – You’ll need 7 ounces grated zucchini, which may be one medium-large one or you might need part of a second one. You can also measure 1 1/2 cups grated if you don’t have a scale. There is no need to peel it.
- Blueberries – Fresh or frozen both work. Add frozen blueberries straight from the freezer, because thawing them can add extra moisture and tint the batter purple.
- Almond Flour & Coconut Flour – I use Wholesome Yum Blanched Almond Flour for a soft, tender crumb. The small amount of Wholesome Yum Organic Coconut Flour is my recent addition to this version — it absorbs excess zucchini moisture, helping the loaf hold together better. I don’t recommend substituting either of these, because replacing either flour in this blueberry zucchini bread recipe can make it too wet or too dry.
- Besti Monk Fruit Allulose Blend – Sweetens the bread without refined sugar, but just as important, it keeps the crumb extra moist. I also use this for the glaze, because unlike most other sweeteners (even powdered ones!), it dissolves smoothly without a gritty texture.
- Unsalted Butter – Make sure it’s softened at room temperature, so it creams smoothly. For a dairy-free option, coconut oil also works.
- Eggs – For structure and lift. I don’t recommend alternatives here, because this blueberry zucchini bread is already very tender.
- Lemon – The lemon juice brightens the blueberries, but I’ve also added optional lemon zest to make the lemon flavor pop. We’re using more juice for the lemon glaze, too!
- Baking Powder (for lift), Vanilla Extract (for flavor), and Sea Salt (for balance)

How To Make Blueberry Zucchini Bread
I have step-by-step photos here to help you visualize the recipe. For full instructions with amounts and temperatures, see the recipe card.
- Prep the zucchini and pan. Grate the zucchini and set it over the sink to drain. While you preheat the oven, line a loaf pan (this is the perfect size) with parchment paper.
- Cream the butter and Besti. In a large bowl, use a hand mixer to beat them together until fluffy.
- Add the wet ingredients. Beat in the eggs, lemon juice, lemon zest (if using), and vanilla extract.
- Mix in the dry ingredients. Beat in the almond flour gradually, 1/2 cup at a time. Then, beat in the coconut flour, baking powder, and sea salt. The batter will be very thick.
- Squeeze and add the zucchini, then the blueberries. Wrap the grated zucchini in cheesecloth or several layers of sturdy paper towels, and squeeze out as much moisture as possible. Stir it into the batter until well combined. Fold in the blueberries.
- Bake the bread. Transfer the batter to the prepared pan, smooth the top, and round it slightly. Bake until the top is light golden. Cover loosely with foil and continue baking until a toothpick inserted in the center comes out clean.
- Cool before glazing. Once your blueberry zucchini bread has completely cooled on a rack, whisk more Besti and lemon juice until smooth. Drizzle on the glaze right before serving.
My Tips For The Best Texture
- I prefer the larger holes on my box grater. Very fine shreds can turn mushy.
- Squeeze the zucchini very (very, very!) well. I usually get at least 1/4 cup of water out. This is key to avoid a wet center or a loaf that falls apart.
- It’s normal for the batter to be very thick — do not thin it out. Resist the urge to add more liquid, or it will never set. The zucchini will add moisture as it bakes (yes, even after being squeezed up front).
- Feel free to adjust the sweetness. This version is pretty sweet with 2/3 cup of Besti, but I’ve also made it with 1/2 cup and that was great, too. Both work fine for this batter.
- Make sure your loaf pan is not too big. I developed this recipe using this exact pan, which is smaller than most. A larger pan will make a flatter loaf and can change the baking time.
- Round the top before baking. This blueberry zucchini bread doesn’t rise very much, so rounding the top upfront helps it have that shape in the end.
- Cover the loaf while the top is still light golden, lighter than you want. It will get more golden even when covered, but covering prevents it from burning before the inside is done.
- Remove the bread from the pan to cool, or it can turn out soggy. I usually let the zucchini blueberry bread rest for 10-15 minutes in the pan so it sets enough to lift out, then transfer to a wire rack to finish cooling.
- Cool completely before slicing. If you slice it while it’s still warm, the inside will be too wet. The texture is even better if you can wait until the next day!
- Add the glaze only right before serving. I find it soaks into the crumb over time, so is best drizzled fresh.
- Want to turn this into muffins? You can! You’ll just need to reduce the baking time. I recommend checking at 20 minutes, but they usually take 25-30 minutes to be done.

Maya’s Recipe Notes
Serving size: 1 slice, 1/2″ thick
- Tips: Check out my recipe tips above to keep the loaf moist, prevent a soggy center, and help every slice hold together.
- Storage: You can keep this blueberry zucchini bread on the counter for about 24 hours, but otherwise it’s best in the refrigerator, since it has fresh zucchini, berries, and so much moisture. If I wrap it in parchment paper (avoid plastic, which traps moisture) and keep in the fridge, it usually lasts up to a week.
- Reheat: Warm individual slices briefly in the microwave or oven. I don’t recommend the toaster, because the loaf is too soft and delicate.
- Freeze: I recommend slicing the cooled bread first, then freeze the pieces in a zip lock bag, with parchment paper between them to prevent sticking. That way, you can grab just a slice (or two) at a time to enjoy.

0Delicious! I didn’t let it cool completely and it came out slightly soggy (I probably could have squeezed more water out of the zucchini too). But flavor was amazing and I used it as “blueberry shortcake.” Cut it into chunks and tossed whipped cream and blueberries on it. Amazing!!
Jodie Gibson
0Hi, I like the look of this recipe and am planning on making it, but i have a question or 2. How does it change the nutrition information if i leave off the glaze? Could I use raspberries instead of blueberries? Thank you 🙂
Wholesome Yum M
0Hi Jodie, I have not tested this recipe using raspberries, but it should work similarly. Just be sure to pat your berries dry before incorporating them into the recipe. I don’t know what the nutrition would be off-hand without the glaze, but feel free to enter the recipe into an online recipe calculator to get an accurate idea of the nutrition.
Michele
0Could I use honey as a sweetner?
Wholesome Yum M
0Hi Michele, Unfortunately not. This recipe needs a dry granulated sweetener.
Gabby
0Is it 1.5 cups zucchini after getting moisture out or before? Just confused how much zucchini to use.
Wholesome Yum M
0Hi Gabby, You want 1.5 cups of grated zucchini total. Once you have that amount measured out, you can start draining off the excess liquid.
Pam
0This recipe is PHENOMENAL! I have an abundance of both zucchini and blueberries, and was looking for a muffin recipe using both. I spooned the batter into muffin tins and baked for about 22 minutes. Next time I will probably try baking muffins at 350° instead of 325°. I will definitely make these again! What a delicious, low-carb treat!
Fran
0Would it be ok to use frozen blueberries?
Wholesome Yum M
0Hi Fran, Yes, Let them defrost and drain the excess water off first before using. Enjoy!
Joy Belcher
0Which way do we use blueberries thawed or keep them frozen?
Wholesome Yum M
0Hi Joy, The recipe will work with either fresh or frozen berries. The images in post use fresh berries which is a little prettier in my opinion, frozen berries will likely turn your bread blue. Be sure to add them while still frozen (don’t thaw) if you do use frozen berries.
Megan Bowes
0I’ve made this twice now and absolutely love it! My husband and neighbors love it, too. It is very easy make. It is moist and just delicious. It’s a favorite!
April
0So yummy. I made the mistake of not letting it cool before pouring on the glaze & it ended up kind of soggy but the flavor was incredible!
Davs
0This was a keeper, I’ve been struggling with baking on keto not enjoying the texture and flavours of the alternatives but I’m pretty satisfied with how this came out. I used raspberries (as I didn’t hv blueberries) and 2c of peeled zucchini that I had grated and frozen, once defrosted was very easy to squeeze the water out and dry. I did let it cool overnight, then cut into 1” slices. Thanks for sharing.
Megan Bowes
0This looks so good (and the batter tastes great). It is still in the oven. You say to cool completely. Should I leave it in the pan overnight to cool? Or should I take it out and let it cool on a rack overnight?
Wholesome Yum M
0Hi Megan, Absolutely let your bread cool before storing it. It will need a couple of hours to completely cool. If you prefer you can leave your loaf out on a cooling rack overnight and then store it in the fridge in the morning. I hope this helps.
Megan Bowes
0Thank you! That’s just what I did. Cooling overnight on a rack was perfect.
Christine Rideout
0I absolutely love this recipe, it’s so moist and full of flavor
Julia
0RecIpe calls for 9×5 pan but the amazon link has a smaller pan. What is the best size?
Wholesome Yum M
0Hi Julia, Both sizes are acceptable. There is only a small amount of difference (1/2 inch) in pan size. You can use either size without changing the recipe amounts or bake time. Enjoy!
Danielle Roof
0Turned out so good!! I used a mini loaf pan & made 9 so I could cut them in half to make it easier to pack in my lunch! First time making this recipe & will definitely be making it again.
Lesha
0Delicious I love this recipe and it comes out great every time. My boyfriend who is not on a keto diet exclaimed it was the best zucchini bread he ever had and loved it too. Does not need icing in my opinion, perfectly sweet without it.
Maureen Hilderbrand
0Wow! Beat my expectation. I changed one thing, I did not put any glaze on it. So tempting, but I let it cool in the pan, then took it out and put in foil put in the refrigerator overnight. Then sliced in the morning, and kept out enough to have one slice each day, and put the rest in the freezer. I think I will try with blackberries to see how that works.
Sue
0Anybody made these as muffins? If so what temperature and for how long?
Wholesome Yum M
0Hi Sue, This recipe will bake up best as a loaf. If you would like to have it in portions, I suggest pre-slicing and freezing.
Pam Lutz
0I just made this recipe as muffins and it worked very well! I divided the batter between 18 paper-lined muffin cups and baked for about 22 minutes (I started lower and kept adding time, so I’m not certain of the total time.) When I bake them again, I plan to bake at 350 instead of 325. I didn’t add any glaze.
Teresa
0Hi Maya,
Can I use the keto bread mix instead of almond flour? If so, what changes, if any, would I need to make?
Thanks,
Teresa
Maya | Wholesome Yum
0Hi Teresa, I haven’t tried that yet. I think you probably could. You’d omit the almond flour and replace with the keto bread mix, and also omit the baking powder and salt because the bread mix has those as well. You’d still want to add the sweetener since the mix isn’t a sweet bread on its own. That’s a good starting point, just check the consistency of the batter in the video to see if it needs more liquid, but the zucchini releases liquid as it bakes, so you wouldn’t need to add almond milk the way you do to the plain mix, you should be able to use the ingredients listed above. Let me know how it goes!
Sam
0Hello,
Is is posssible to use monk fruit instead of erythirtol?
Wholesome Yum M
0Hi Sam, If it’s a monk fruit erythritol blend, then yes it will work. If you have pure monk fruit, it will not. Check out this sweetener calculator to help you determine how much sweetener you will need for the recipe.
Sam
0Hello is it possible to use ghee instead of butter
Wholesome Yum M
0Hi Sam, Yes, ghee will work fine.
Shanna
0This bread was absolutely delicious! It not only satisfied my sweet tooth, but everyone else in my family loved it as well. First couple times I made it I also had a problem with it being a little soggy. This last time I squeezed the zucchini out a few more times and it turned out perfect!
