I still have lots of zucchini in the garden, and I got blueberries at the store so I decided to try making Zucchini Bread that had a few Blueberries! My first attempt was not a keeper, but I loved this  Zucchini Bread with Blueberries that I came up with for the second try. 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! 

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. 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.

What ingredients do you need for this recipe?

Can you use frozen blueberries for this recipe?

You can definitely make this with partly-thawed frozen blueberries if that’s what you have.

What other kind of nuts can you use?

If you don’t have pecans, walnuts or almonds would also be good in this recipe.

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
Yield: 12 slices

Low-Sugar Whole Wheat Zucchini Bread with Blueberries

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.)
