These Moist Cinnamon Zucchini Muffins are soft, tender, warmly spiced, and packed with freshly shredded zucchini.

They’re an easy way to turn summer zucchini into a simple homemade breakfast or snack. Brown sugar keeps the centers moist, cinnamon adds plenty of cozy flavor, and a light cinnamon-sugar topping gives each muffin a slightly crisp, sweet top.

No mixer is required, and the batter comes together quickly in two bowls.

Easy Homemade Zucchini Muffins

Fresh zucchini is perfect for baking because it contains plenty of natural moisture without adding a strong vegetable flavor.

Once shredded and folded into muffin batter, the zucchini practically disappears while helping create an incredibly soft texture.

These muffins use a combination of brown sugar, vegetable oil, vanilla, and cinnamon to create a simple batter that stays moist even after the muffins have cooled.

The zucchini is lightly squeezed before being added. This removes excessive water without taking away all the moisture that makes zucchini muffins so tender.

Before baking, each muffin gets a small sprinkle of cinnamon sugar.

That creates a lightly crisp, sparkling top that contrasts beautifully with the soft center.

🛒 Ingredients

For the Zucchini Muffins

Fresh Zucchini

Use fresh medium zucchini.

There’s no need to peel it before grating.

The green skin creates subtle flecks throughout the muffins but doesn’t affect their soft texture.

All-Purpose Flour

Regular all-purpose flour provides structure while keeping the muffins tender.

Baking Soda

Baking soda helps the muffins rise and contributes to browning.

Baking Powder

A little baking powder provides additional lift for taller muffin tops.

Ground Cinnamon

Cinnamon is the primary spice in these muffins.

It gives them their warm, cozy flavor without overpowering the zucchini.

Ground Nutmeg

A small amount of nutmeg adds depth to the cinnamon.

Salt

Salt balances the sweetness and enhances the other flavors.

Eggs

Eggs provide structure and help bind the batter together.

Light Brown Sugar

Brown sugar contributes both sweetness and moisture.

Its subtle molasses flavor also pairs beautifully with cinnamon.

Granulated Sugar

A smaller amount of granulated sugar balances the brown sugar.

Vegetable Oil

A neutral vegetable oil keeps the muffins moist even after they cool.

Vanilla Extract

Vanilla adds warmth and rounds out the cinnamon flavor.

For the Cinnamon-Sugar Topping

Granulated Sugar

Creates a lightly crisp, sparkling muffin top.

Ground Cinnamon

Adds another layer of cinnamon flavor directly to the surface.

👩‍🍳 How to Make Moist Cinnamon Zucchini Muffins

1. Prepare the Oven

Preheat the oven to 350°F (175°C).

Line a standard 12-cup muffin pan with paper liners.

2. Shred the Zucchini

Wash and dry the zucchini.

Don’t peel it.

Use the large holes of a box grater to shred it.

You need approximately 1½ cups shredded zucchini.

3. Remove Excess Moisture

Place the shredded zucchini inside a clean kitchen towel.

Gently squeeze it several times to remove obvious excess water.

Don’t twist and squeeze until the zucchini is completely dry.

We still want some natural moisture remaining.

4. Combine the Dry Ingredients

In a medium mixing bowl, whisk together:

• All-purpose flour
• Baking soda
• Baking powder
• Cinnamon
• Nutmeg
• Salt

Set the bowl aside.

5. Combine the Wet Ingredients

In a large bowl, whisk the eggs.

Add:

• Brown sugar
• Granulated sugar
• Vegetable oil
• Vanilla extract

Whisk until the mixture is smooth and evenly combined.

6. Add the Zucchini

Stir the lightly squeezed shredded zucchini into the wet ingredients.

Make sure it’s distributed throughout the mixture rather than sitting in one large clump.

7. Combine Wet and Dry Ingredients

Add the dry ingredients to the wet mixture.

Use a silicone spatula to fold everything together gently.

Stop as soon as the flour disappears.

Don’t continue stirring until the batter becomes completely smooth.

Small lumps are normal.

8. Make the Cinnamon Sugar

In a small bowl, combine the granulated sugar and cinnamon.

Stir until evenly mixed.

9. Fill the Muffin Cups

Divide the batter evenly between the 12 muffin cups.

Fill each approximately ¾ full.

The portions don’t need to be perfectly identical.

10. Add the Cinnamon-Sugar Topping

Sprinkle a small amount of cinnamon sugar over each muffin.

Don’t create an excessively thick sugar layer.

A light coating is enough.

11. Bake

Bake for approximately 18–22 minutes.

The muffins are ready when the tops spring back lightly when touched and a toothpick inserted into the center comes out clean or with a few moist crumbs.

12. Cool in the Pan

Let the muffins cool in the pan for approximately 5 minutes.

13. Transfer to a Cooling Rack

Carefully remove the muffins and place them on a wire rack.

Allow them to cool slightly before serving.

They’re especially good while still a little warm.

✨ Variations

Chocolate Chip Zucchini Muffins

Fold ¾ cup semi-sweet or mini chocolate chips into the batter.

Walnut Zucchini Muffins

Add approximately ½ cup chopped walnuts.

Pecan Zucchini Muffins

Replace the walnuts with chopped pecans.

Raisin Zucchini Muffins

Fold approximately ½ cup raisins into the batter.

Zucchini Carrot Muffins

Replace approximately half of the zucchini with finely shredded carrot.

Cinnamon Streusel Zucchini Muffins

Replace the simple cinnamon sugar with a buttery brown-sugar streusel topping.

Lemon Zucchini Muffins

Leave out the nutmeg and add fresh lemon zest for a brighter version.

🔥 Tips for the Best Zucchini Muffins

Don’t peel the zucchini. The skin becomes tender during baking and gives the muffins natural green flecks.

Grate it yourself. Freshly shredded zucchini provides the best moisture and texture.

Lightly squeeze the zucchini. Removing too much liquid can make the muffins drier than intended.

Measure your flour carefully. Packing flour into the measuring cup can create dense muffins.

Don’t overmix. Overmixing develops more gluten and can make the muffins tough.

Use oil rather than melted butter. Oil helps the muffins stay soft longer.

Don’t overfill the cups. About three-quarters full gives the batter room to rise.

Check them early. Muffin ovens vary, so begin checking around 18 minutes.

Don’t overbake. Even a few extra minutes can noticeably reduce moisture.

🥡 Storage

Room Temperature

Allow the muffins to cool completely.

Store them in an airtight container at room temperature for up to 3 days.

You can place a paper towel underneath them to absorb excess surface moisture.

Refrigerator

Store refrigerated in an airtight container for up to 1 week.

Let them come to room temperature before serving or warm briefly.

Freezer

These zucchini muffins freeze very well.

Place completely cooled muffins in a freezer-safe container or bag.

Freeze for up to 3 months.

Thawing

Thaw individual muffins at room temperature or overnight in the refrigerator.

You can also warm a thawed muffin briefly before serving.
