Moist Cinnamon Swirl Zucchini Bread Recipe

July 20, 2025

This moist cinnamon swirl zucchini bread is a treat for your taste buds! Packed with fresh zucchini and a lovely swirl of cinnamon, it’s perfect for breakfast or a snack.

Don’t be surprised if your kitchen smells like a bakery! I love serving it warm with a little butter on top. It’s a cozy delight, and trust me, you won’t be able to stop at one slice! 🍞

Key Ingredients & Substitutions

Zucchini: Fresh zucchini adds moisture and texture to the bread. If you don’t have any zucchini, you can try using grated carrots for a similar effect, but it will change the flavor profile slightly.

Flour: All-purpose flour is standard here, but you can substitute whole wheat flour for a nuttier taste and extra fiber. Just note that it might make the bread denser.

Sugar: For a healthier option, you can replace granulated sugar with coconut sugar or honey. If using honey, reduce some liquid in the recipe to keep the right consistency.

Nuts: I love adding walnuts or pecans for extra crunch. If you’re allergic or just don’t want nuts, feel free to skip them or replace with sunflower seeds.

How Do You Get the Perfect Cinnamon Swirl?

The cinnamon swirl is what makes this bread special! To achieve a lovely swirl effect, you’ll want to layer the batter and cinnamon sugar properly. Here’s a simple method:

  • Pour half the zucchini bread batter into a greased pan.
  • Evenly sprinkle half of the cinnamon sugar mixture on top.
  • Pour the remaining batter over, and top with the rest of the cinnamon sugar.
  • Use a knife or skewer and lightly drag it through the batter in a swirling motion without completely mixing it in.

This method allows the cinnamon to create those beautiful, swirled lines throughout the bread as it bakes. Enjoy the smell while it bakes, too—it’s wonderful!

  • 2 cups grated zucchini (about 2 medium zucchinis)
  • 2 cups all-purpose flour
  • 1½ tsp baking soda
  • ½ tsp baking powder
  • ½ tsp salt
  • 1 tsp ground cinnamon (for the bread batter)
  • 1½ cups granulated sugar
  • ¾ cup vegetable oil
  • 3 large eggs
  • 2 tsp vanilla extract
  • ½ cup chopped walnuts or pecans (optional)

For the Cinnamon Swirl:

  • 1½ tsp ground cinnamon

How Much Time Will You Need?

This recipe takes about 20 minutes of prep time, along with 55–65 minutes for baking time. Total time from start to finish is around 1 hour and 20 minutes, including cooling. Get ready for some deliciousness!

Step-by-Step Instructions:

1. Preheat and Prepare:

Start by preheating your oven to 350°F (175°C). While it heats, grease and flour a 9×5 inch loaf pan to make sure your bread comes out easily once it’s baked.

2. Mix the Dry Ingredients:

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and 1 tsp of cinnamon. This helps to ensure everything is evenly distributed which will make for a better rise!

3. Combine the Wet Ingredients:

In a large bowl, beat the eggs and granulated sugar together until well combined. Add in the vegetable oil and vanilla extract, and mix until everything is nicely blended.

4. Combine Wet and Dry Mixtures:

Now it’s time to add the dry mixture to the wet mixture. Stir it together gently until just combined. Don’t worry if there are a few lumps—overmixing can make the bread tough!

5. Add the Zucchini and Nuts:

Fold in the grated zucchini (this is what makes the bread moist) and the chopped nuts if you’re using them. Be careful not to stir too hard—just incorporate everything gently.

6. Prepare the Cinnamon Swirl Mixture:

In a small bowl, mix together the brown sugar and the remaining 1½ tsp of cinnamon. This mixture will create the delicious swirl in your bread!

7. Layering the Batter in the Pan:

Pour half of the zucchini bread batter into your greased loaf pan. Then, sprinkle half of the cinnamon sugar mixture evenly over the batter. Pour the rest of the batter on top and finish with the remaining cinnamon sugar mixture.

8. Create the Swirl:

Using a knife or skewer, gently swirl the cinnamon sugar into the batter by dragging it in a zigzag or circular motion. This will give your zucchini bread that lovely swirly effect!

9. Bake!

Now, place the pan in the oven and bake for 55–65 minutes. You’ll know it’s ready when a toothpick inserted into the center comes out clean. Your kitchen will smell amazing!

10. Cooling Time:

Once baked, allow the bread to cool in the pan for about 15 minutes. Then, carefully transfer the bread to a wire rack to cool completely. This waiting is the hardest part!

11. Serve and Enjoy:

After your bread has cooled, slice it up, and enjoy your moist, flavorful cinnamon swirl zucchini bread! It pairs beautifully with a cup of coffee or tea.

This bread stays moist thanks to the zucchini and oil, with a sweet, aromatic cinnamon swirl throughout. Happy baking!

Yes, frozen zucchini can be used! Just make sure to thaw it completely and blot away excess moisture with paper towels before grating and adding it to the batter. This will help prevent the bread from becoming too soggy.

How Can I Make This Bread Healthier?

You can make a few simple substitutions to lighten it up! Use whole wheat flour instead of all-purpose, and replace some or all of the granulated sugar with coconut sugar or a sugar substitute. You could also substitute unsweetened applesauce for some of the oil for a lower-fat option.

Can I Make This Bread Without Nuts?

Absolutely! If you prefer not to use nuts or have a nut allergy, simply leave them out. The bread will still be delicious and moist without them. You could also consider adding chocolate chips or raisins for extra flavor!

What’s the Best Way to Store Leftovers?

Store any leftover zucchini bread in an airtight container at room temperature for up to 3 days. If you want to keep it longer, you can wrap it tightly and freeze it for up to 3 months. Just be sure to thaw it in the fridge overnight before enjoying!
