Step-by-Step Cooking Instructions
1: Prepare the Oven and Pan
Preheat your oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan or line it with parchment paper for easy removal.
2: Prepare the Zucchini
Wash and grate the zucchini using a box grater. Gently squeeze out excess moisture with a clean kitchen towel, but avoid removing all the liquid since some moisture helps keep the bread soft.
3: Mix the Wet Ingredients
In a large mixing bowl, whisk together:
- Eggs
- Greek yogurt
- Honey or maple syrup
- Vanilla extract
Mix until smooth and fully combined.
4: Add the Zucchini
Fold the grated zucchini into the wet ingredients, distributing it evenly throughout the mixture.
5: Combine the Dry Ingredients
In a separate bowl, mix:
- Whole wheat flour
- Protein powder
- Baking powder
- Baking soda
- Cinnamon
- Salt
Stir thoroughly to eliminate any clumps.
6: Create the Batter
Gradually add the dry ingredients to the wet mixture. Stir gently until no dry streaks remain. Avoid overmixing, as this can make the bread dense.
7: Transfer to the Loaf Pan
Pour the batter into the prepared loaf pan and spread it evenly with a spatula.
8: Bake
Place the pan in the preheated oven and bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean.
9: Cool Completely
Allow the bread to cool in the pan for about 10 minutes before transferring it to a wire rack. Let it cool completely before slicing.

For the best texture, mix the batter only until the ingredients are combined. Overmixing can result in a dense loaf.
FAQs
1. Can I make high-protein zucchini bread without protein powder?
Yes. You can replace the protein powder with additional whole wheat flour, oat flour, or almond flour. However, the overall protein content of the bread will be lower.
2. Do I need to peel the zucchini before grating it?
No. The zucchini skin is soft, nutritious, and blends seamlessly into the bread. Simply wash the zucchini thoroughly before grating.
3. How do I keep zucchini bread from becoming too wet?
Lightly squeeze excess moisture from the grated zucchini before adding it to the batter. Avoid removing all the moisture, as some is necessary for a soft and tender texture.

Vanilla whey protein powder is a popular choice because it adds sweetness and flavor. Plant-based protein powders can also work, though they may create a slightly denser loaf.
