I still have lots of zucchini in the garden, and I got blueberries at the store so I decided to try making zucchini bread with blueberries! My first zucchini bread attempt was not a keeper, but for the second try I came up with this Low-Sugar Whole Wheat Zucchini Bread with Blueberries that I really liked. I’ll always be more of a cook than a baker, but I was excited that I managed to adapt ideas from a few different recipes and get lower-sugar zucchini bread that actually worked.

Of course blueberries have some sugar, but I used Golden Monkfruit Sweetener for the sweetener and white whole wheat flour for a healthier zucchini bread! Putting blueberries in was an impulse that worked out, but if you don’t have blueberries I think you could use another cup of zucchini (with maybe a bit more cinnamon) or add some other type of fruit.

And last night I made dinner for my sister Pam, her husband Kelly, and my niece Alyson (after Kelly hooked up my new natural gas grill, thanks Kelly!) and they gave the zucchini bread three thumbs up.

How to Make Low-Sugar Whole Wheat Zucchini Bread with Blueberries:

(Scroll down for complete recipe with nutritional information.)

  1. Mix white whole wheat flour, baking powder, baking soda, cinnamon, and salt in a small bowl.
  2. This next step made me wish I had a KitchenAid stand mixer, but I used my hand mixer to beat the eggs and sweetener, and it worked great.
  3. Once eggs have tripled in size, add the canola oil and vanilla and stir to combine.
  4. Then stir in one cup of grated zucchini. (Since I only used one cup of zucchini, I just grated it by hand this time.)
  5. Next mix the dry ingredients into the wet ingredients.
  6. The batter will be very stiff. If it seems like it will be too stiff to be able to mix in the nuts and blueberries, add 1-2 T water.
  7. Gently stir in the fresh or thawed blueberries and chopped pecans, just mixing enough to get them distributed in the batter.
  8. Spray a loaf pan with non-stick spray or oil, then put batter in and spread around. (I used a rubber scraper to get the stiff mixture to fill the pan evenly, and at this point I wondered whether the recipe was going to work!)
  9. Here’s how the finished loaf looked as it was cooling in the pan, probably not good-looking enough to win any baking awards, but this was definitely tasty!

Low-Sugar and Whole Wheat Zucchini Bread with Blueberries and Pecans

Low-Sugar Whole Wheat Zucchini Bread with Blueberries

Yield 12 slices
Prep Time 20 minutes
Cook Time 50 minutes
Total Time 1 hour 10 minutes

Low-Sugar Whole Wheat Zucchini Bread with Blueberries is made with no added sugar.


  • 1 3/4 cups white whole wheat flour (see notes)
  • 2 tsp. baking powder
  • 1/2 tsp. baking soda
  • 1/2 tsp. ground cinnamon (see notes)
  • 1 cup Golden Monkfruit Sweetener (see notes)
  • 2 large eggs
  • 1/2 cup vegetable oil
  • 1 tsp. vanilla (I used Mexican vanilla)
  • 1 cup coarsely grated zucchini (I just grated with the big side of a hand grater)
  • 1-2 T water (as needed, if batter is too stiff, I used 1 T water)
  • 1 cup fresh or thawed blueberries
  • 1/2 cup chopped pecans


  1. Preheat oven to 350F (175C) and spray loaf pan with oil or non-stick spray.
  2. Most recipes I saw called for 8″ x 4″loaf pan, but my pan was 9″ x 5″ and it was fine.
  3. In a small bowl, combine white whole wheat flour, baking powder, baking soda, cinnamon, and salt.
  4. In a bowl that’s large enough to hold all the ingredients, beat the sweetener and eggs with an electric mixer or hand beater until the eggs triple in size, about 5 minutes.
  5. Stir in canola oil and vanilla, then stir in grated zucchini.
  6. Add the flour mixture to the wet ingredients and stir until combined.
  7. The mixture will be stiff, but if it seems too stiff to be able to add blueberries and pecans add 1-2 T water.
  8. Fold in blueberries and pecans, mixing just enough to get them distributed in the batter.
  9. Spread the mixture into loaf pan.
  10. Bake zucchini bread 45-50 minutes, or until toothpick tester stuck into the center of the loaf comes out clean. (For me that took 50 minutes, but I was baking it in a toaster oven.)
  11. Let the bread cool in the loaf pan on a wire rack for 10 minutes, then use a knife to run around the edge of the bread and remove the loaf to cool a few minutes more on the wire rack before slicing.
  12. This bread is great warm or cold.
  13. I’ve been eating it re-heated in the microwave for about a minute, which works great. (If anyone tries freezing this, I’d love to hear how it works.)

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
This Whole Wheat Zucchini Bread with Blueberries is made with Golden Monkfruit Sweetener, so this recipe would be good for phase 2 or 3 of the original South Beach Diet and it’s also a fairly low-glycemic recipe, but it’s too high in carbs for traditional low-carb diet plans. It’s a fairly calorie-dense recipe, so for South Beach Phase Two don’t overdo it on the portion size.

  1. Kalyn, your are getting better at baking. Love this!!

  2. This is such a lovely recipe Kalyn!..pictures are so drool worthy!

  3. Kalyn – I was just wondering what else I could do with the glut of zucchini the garden has produced this year. This looks like a wonderful addition to my repertoire, though I, like you, am more of a cook than a baker. I was surprised to read you wish you had a KA stand mixer. I only own a hand mixer and have been trying for years to discover the right stand mixer to purchase but if a hand mixer works so well for you, maybe I will just stay with it!

  4. That looks like an excellent zucchini bread – and I always love blueberries! I usually toss the berries (while frozen or fresh) with a little flour so the berries don't sink – but yours look just fine. Speaking of blueberries, this morning I made blueberry muffins, tossing the berries with flour and a little lemon verbena sugar – then forgot to add the sugar! Can you believe the muffins tasted almost the same without the extra sugar? I was really surprised. ( I whizzed a few leaves of lemon verbena in the food processor, then added two T. sugar and whizzed again, then sprinkled it on the berries)

  5. Oh my, I almost let zucchini season pass me by, thanks for the reminder! That bread looks lovely.

  6. I keep seeing recipes for zucchini breads, and I have yet to try one. This one looks so marvelous-full of color and great ingredients!

  7. This looks delicious! I'm defn. going to try this one!!! I love zucchini bread and never thought to add blueberries. And I love pecans. Can't wait to get some zucchini and try!

  8. I have both blueberries and zucchini in plenty…and if not, the local market will supply! Thanks for the great idea.

  9. Thank you for the nice comments everyone. Lisa, I'm avoiding sugar so I just use granulated Splenda, but the Splenda for Baking would definitely work if you don't mind the sugar.

  10. Kalyn,

    When you list Splenda in your ingredients, do you use Splenda for baking (1/2 sugar & 1/2 Splenda) or just regular Splenda granulated?


  11. This is such a great blog.

  12. I want to bite this cake. Good post.

  13. Adding blueberries to a zucchini bread is a great idea! I really like the blues and greens in that bread!

  14. I love that you added in blueberries! I added dried cranberries to mine and loved that. I can't wait to try the fresh fruit!

  15. This looks really terrific. I made a much more sugar/fat laden version a couple of summers ago w/ zucchini + blueberries. It's a wonderful combination.

    I was just looking at some zucchini sweet recipes yesterday. Seems like the right time of year to experiment with it since most gardens are bursting with it at this point in the summer!

  16. Blogger is posting comments after I've already replied again, but Dara (Cookin' Canuck above) thank you for the great savory zucchini bread ideas!

  17. Rebecca, thanks for the nice feedback. I love FBS too, use it all the time. Would love to hear how that recipe turns out, so come back and leave the link if it's a keeper!

    Rachael, the blueberries were great in this. I'm not much of a fruit-eater, so I'm always trying to find ways to eat more fruit, especially the fruits like blueberries that are so nutritious!

  18. Kalyn, this looks moist & tasty! I think the blueberries would be lovely with the zucchini. And I do love that the bread is whole wheat.

    Ideas for savory zucchini bread: caramelized onion & Parmesan cheese, roasted red pepper & goat cheese or feta, smoked cheddar & green onions, curry zucchini bread…

  19. When I made zucchini bread for my kids they loved it. I would have never of thought to make it before I had them, but now I am always looking for new recipes to expand their little taste buds. Next one I try will have to have some blueberries in it, and maybe some pecans. They aren't the biggest nut fans yet.

  20. Kalyn – I have been a long time reader of your website – I love it! I have really learned how to cook and think for myself in the kitchen – you've helped me overcome my frozen-dinner/fast food habits. Not to mention that you're also teaching my husband these things by proxy (he cooks about half the time). I appreciate your work so much!

    Also, you introduced me to the foodblogsearch – which is absolutely indispensable for me. I had the same idea and consulted the search for a savory zucchini bread. I was going to adapt one of the savory zucchini recipes I found on there for onion/parmesan savory zucchini bread – essentially a lot less sugar with 1/2c parm and some sautéed onions – add a little bit of oregano/thyme. I haven't tried it yet as I am out of eggs, but I hope to tonight. I will let you know how it goes!
