❓ FAQs

Can I use frozen zucchini?

Yes, but thaw it completely and drain off any excess liquid. Lightly blot with a paper towel before using.

Do I need to peel the zucchini?

No, the peel is soft and blends into the bread. Plus, it adds extra color and nutrients.

Can I make this gluten-free?

Yes, you can substitute a 1:1 gluten-free all-purpose flour blend. Results may vary slightly depending on the brand.

Why is my bread sinking in the middle?

This usually happens if it’s underbaked or if the batter was overmixed. Always check doneness with a toothpick before removing it from the oven.

Can I reduce the sugar?

Yes, you can reduce it slightly without affecting the texture too much. Try cutting back by 1/4 cup if needed.
