I have always been a lover of sweet breads and blueberries are one of my all-time favorite summer fruits. So, I decided to put the two together. The sweetness of the blueberries along with their mild acidic flavor pairs nicely with the soft floral sweetness of the zucchini. The lemon glaze on top adds just the right amount of tartness to cut through the sweet flavor and adds an extra depth of flavor. 

Blueberries are a great addition to sweet breads and you can use fresh or frozen berries. When you add blueberries to your batter, toss them in a little bit of flour first. This helps the blueberries adhere to the batter and keeps them from sinking to the bottom while baking. Just make sure to account for the flour you used for the blueberries to your baking dry ingredients.

Zucchini is also great for sweet breads, because it makes the bread soft and moist. You can also use fresh or frozen zucchini. Zucchini does not need to be peeled before shredding and overgrown slightly bitter zucchini, you sometimes find in your garden, can be used without compromising the flavor of your bread.

A healthy option

As an added bonus to this delicious sweet bread I use white spelt flour, maple syrup (actually, I used agave nectar when I made a video for this recipe but now I read some information that it’s not the best sweetener to use so I recommend sticking to maple syrup), and a healthy cashew lemon glaze (no powdered sugar or any powdered sweetener at all!). So there is no guilt.

Spelt flour has a nutty softly sweet flavor to it, which tastes great with the zucchini. Spelt flour contains many health benefits that traditional white flour does not. It’s packed with protein and fiber. It is also more water-soluble, which makes it easier for the body to digest it. BUT you can easily use all-purpose flour instead if you want to. The bread just won’t be as nutritious.

Maple syrup contains antioxidants and minerals so it’s a way better option than refined sugar.

A cashew lemon glaze is made with only cashew butter, lemon juice, maple syrup, and almond milk. No powdered sugar or any other powdered sweetener! And it looks good on your bread. And it tastes amazing too! It’s one of my most favorite discoveries lately.


Your kids will fall in love with this bread too and it is a yummy (and sneaky) way to get some good fiber and nutrients into their diet after a long day of play in the hot summer sun. It can also be baked in muffin tins to make an easy grab-and-go breakfast or pre-football game snack.

This bread literally melts in your mouth and the cashew lemon glaze is like a cherry on top. It makes this already great bread even better! Once you make this healthy blueberry zucchini bread once, you won’t be able to resist making it again and again. Take my word for it, it is a must-try.

This is now my new favorite summertime bread, but a close second is definitely my Strawberry Rhubarb Bread and Banana Walnut Bread. Give all of them a try and then tell me what you think. 

This Blueberry Zucchini Bread is super delicious and really easy to make. It will become your instant favorite! |

    Wondering when to top the bread with glaze? While it it still warm, or after it has cooled?
