- ⅓ cup (65 g) brown sugar

👩🍳 Instructions
1. Prepare the Zucchini
Preheat the oven to 350°F (175°C).
Grease a 9 × 5-inch loaf pan and line it with parchment paper, leaving some overhang for easy removal.
Finely shred the zucchini.
If the zucchini is extremely watery, gently squeeze out some—but not all—of the excess moisture with a clean kitchen towel.
Don’t completely dry the zucchini. Its moisture is what helps make the bread tender.
2. Make the Cinnamon Swirl
In a small bowl, combine the brown sugar, cinnamon, flour, and melted butter.
Mix until the ingredients form a moist, crumbly mixture.
Set aside.
3. Mix the Wet Ingredients
In a large bowl, whisk together the eggs, vegetable oil, Greek yogurt, granulated sugar, brown sugar, and vanilla extract.
Whisk until smooth and well combined.
4. Add the Zucchini
Stir the shredded zucchini into the wet mixture until evenly distributed.
5. Combine the Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, and nutmeg.
Gradually add the dry ingredients to the zucchini mixture.
Fold gently with a spatula just until no dry streaks remain.
Do not overmix, or the bread can become dense.
If using nuts, fold them in now.
6. Layer the Batter and Cinnamon Swirl
Pour about half of the batter into the prepared loaf pan.
Spread it into an even layer.
Sprinkle the cinnamon swirl mixture evenly over the batter.
Pour the remaining batter over the cinnamon layer and gently spread the top smooth.
For an extra-pretty swirl, run a butter knife through the batter in a few gentle zigzag motions.
7. Bake
Place the loaf in the center of the preheated oven.
Bake for 50–60 minutes, or until:
- The top is golden brown.
- The center springs back lightly when touched.
- A toothpick inserted into the center comes out clean or with a few moist crumbs.
If the top begins browning too quickly, loosely cover the loaf with aluminum foil during the final 15 minutes.
8. Cool
Allow the zucchini bread to cool in the pan for 10–15 minutes.
Use the parchment overhang to carefully lift the loaf onto a wire rack.
Let it cool for at least 30 minutes before slicing.
For the cleanest cinnamon swirl, allow the loaf to cool almost completely before cutting.
⭐ Chef’s Tips
Don’t over-squeeze the zucchini: A little moisture is essential for a soft loaf.
Don’t overmix the batter: Fold until just combined for the most tender texture.
Use fresh cinnamon: Freshly opened ground cinnamon gives the swirl a much stronger aroma.
Let it cool: The crumb continues setting as the loaf cools.
For a stronger swirl: Add an extra tablespoon of cinnamon sugar to the center before adding the top layer of batter.
For bakery-style slices: Sprinkle the top with a little cinnamon sugar before baking.
🍂 Easy Variations

Fold ½ cup toasted chopped walnuts into the batter.
Chocolate Chip Zucchini Bread
Add ½ cup semi-sweet chocolate chips for a chocolate-cinnamon combination.
Cream Cheese Swirl
Spread a thin layer of sweetened cream cheese between the batter layers before adding the cinnamon swirl.
Maple Zucchini Bread
Replace the vanilla with 1 teaspoon maple extract and add a light maple glaze after cooling.
Lemon Zucchini Bread
Add the finely grated zest of 1 lemon for a bright contrast to the cinnamon.
Apple Cinnamon Zucchini Bread
Fold ½ cup finely diced peeled apple into the batter for extra moisture and autumn flavor.

🧊 Storage
Store the cooled zucchini bread in an airtight container at room temperature for 2–3 days.
