A garden that was exploding with zucchini was definitely the motivation to make this Sugar-Free Whole Wheat Chocolate Zucchini Bread. And when I got it into my mind to make chocolate zucchini bread. I wanted the bread to be more chocolate tasting than sweet, low in sugar, and to use a lot of zucchini, and when I began looking for recipes, I didn’t find one that seemed like quite what I had in mind so I started experimenting.

If I were a little more intuitive about baking, it might not have taken me five tries to come up with the winning combination for this tasty sugar-free zucchini bread, but I figure my baking skills can only get better with all this practice! Happily I loved the final version of this bread, and if you like chocolate things that aren’t super sweet and you have zucchini that needs to be used, I hope you’ll give this recipe a try.

What ingredients do you need for this recipe?

What sweetener did I use for this sugar-free zucchini bread?

I originally made this with some brown sugar added to the sweetener. But now that I’ve discovered Golden Monkfruit Sweetener (affiliate link) I’d happily use that to get that brown-sugar flavor in a sugar-free zucchini bread recipe.

Is this Zucchini Bread recipe low in carbs?

This chocolate zucchini bread does have some flour but there’s also quite a bit of zucchini so it has about 11 net carbs per slice. If you’d like a zucchini bread option with fewer carbs, check out Flourless Breakfast Muffins with Zucchini and Feta or Flourless Zucchini Muffins.

Notes

Now that I've discovered Golden Monkfruit Sweetener (affiliate link) I would definitely use that for the sweetener for this recipe! But use any sweetener you prefer. Use any neutral-flavored oil for this recipe. I used White Whole Wheat Flour (affiliate link) and haven't tested the recipe with regular whole wheat flour.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Even though this Sugar-Free Zucchini Bread uses a sugar-free sweetener, this may not be low enough in carbs for low-carb diet plans and is probably Phase 3 for the original South Beach Diet.
