Irresistible Bakery-Style Orange Cardamom Zucchini Muffins (Incredibly Moist!)

Zucchini season usually arrives with a bang. During the Summer I’m always looking for ways to turn that overflowing harvest into something that feels a little special. Classic zucchini bread is great, and will always have a place in my kitchen. However, sometimes I want a recipe that’s a little more exciting.

These Orange Cardamom Zucchini Muffins are exactly that.

Fresh orange zest brightens every bite, fragrant cardamom adds a warm floral spice, and shredded zucchini keeps the muffins unbelievably moist without making them taste like vegetables. Finished with a glossy orange glaze, they’re elegant enough for brunch, easy enough for a weekday breakfast, and beautiful enough to share with friends. They get rave reviews from my coworkers when I take them to work.

If you’re growing zucchini this summer, this recipe is one you’ll find yourself making again and again. If you’re not growing zucchini yet, but would like to, check out this guide on How to Grow Summer Squash in Small Spaces.

Why You’ll Love These Muffins

Unlike many zucchini muffins that lean heavily on cinnamon, these have a lighter, more sophisticated flavor profile.

You’ll love them because:

• Wonderfully moist crumb thanks to fresh zucchini
• Bright citrus flavor from real oranges
• Warm, aromatic cardamom without being overpowering
• Simple orange glaze that makes them feel extra special
• Great for breakfast, brunch, or afternoon coffee (or tea!)
• Perfect balance of sweetness between the muffins and glaze

They’re the kind of muffin that feels right at home beside a cup of tea on the porch or tucked into a picnic basket.

Why Zucchini Works So Well in Baking

One of the biggest surprises for first-time zucchini bakers is that you rarely taste the zucchini itself.

Instead, it quietly works behind the scenes by adding moisture and tenderness to cakes, muffins, breads, and bars. That extra moisture helps baked goods stay soft for days, which is one of the reasons zucchini has become such a favorite ingredient for summer baking.

The key is using the right amount and preparing it correctly.

A Flavor Combination That Feels Like a Bakery

Orange and cardamom have been paired together for generations, and for good reason.

Fresh orange zest brings brightness and natural sweetness, while cardamom adds subtle floral and citrus notes that make these muffins taste a little more refined than your average zucchini muffin.

Neither flavor overwhelms the other. Instead they create a balance that the moisture from the zucchini helps elevate.

The result is a muffin that’s fresh, lightly spiced, and perfect for summer when gardens are overflowing with zucchini and citrus flavors feel refreshing on a warm day.

Baking Instructions

1. Prepare the Oven

Preheat the oven to 425°F (218°C).

Line a standard 12-cup muffin pan with paper liners or lightly grease the cups.

2. Mix the Dry Ingredients

In a large bowl, whisk together:

• Flour
• Baking powder
• Baking soda
• Salt
• Cardamom
• Cinnamon
• Nutmeg (if using)

Set aside.

3. Mix the Wet Ingredients

In another large bowl, whisk together:

• Melted butter
• Avocado oil
• Granulated sugar
• Brown sugar

Whisk until smooth.

Add:

• Eggs
• Vanilla
• Orange zest
• Orange juice
• Greek yogurt

Whisk until fully combined.

Fold in the shredded zucchini.

4. Combine

Add the dry ingredients to the wet ingredients.

Using a rubber spatula, gently fold together until only a few streaks of flour remain if incorporating add ins. If not, fold together until just mixed.

If using, gently fold in the white chocolate.

Do not overmix.

The batter will be thick.

5. Rest the Batter

Allow the batter to rest for 20 minutes.

This simple step helps hydrate the flour and creates taller bakery-style muffin tops.

6. Fill the Muffin Pan

Divide the batter evenly among the prepared muffin cups, filling each nearly to the top.

7. Bake

Bake at 425°F for 7 minutes.

Without opening the oven, reduce the temperature to 350°F (177°C).

Continue baking for 12–15 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.

The internal temperature should reach approximately 205°F.

8. Cool

Allow muffins to cool in the pan for 5–10 minutes before transferring them to a wire rack.

Cool completely before glazing.

9. Make the Glaze

Whisk together:

• Powdered sugar
• Orange juice
• Vanilla
• Pinch of cardamom

Adjust with additional orange juice until the glaze is thick but pourable.

Drizzle generously over cooled muffins.

Allow the glaze to set for about 15 minutes before serving.

Baker’s Tips for Perfect Muffins

Don’t Skip the Orange Zest

Most of the orange flavor comes from the zest, not the juice.

Take your time zesting only the bright orange portion of the peel, avoiding the bitter white pith underneath.

Rest the Batter

After mixing, let the batter rest for about 20 minutes before baking.

This simple step hydrates the flour, thickens the batter slightly, and helps create those beautiful bakery-style muffin tops.

Start Hot, Then Lower the Temperature

Beginning the bake at 425°F gives the muffins an immediate burst of oven spring.

Lowering the temperature after several minutes allows the centers to bake through without drying out the tops.

Don’t Overmix

Fold the batter together just until no dry streaks remain.

Overmixing develops gluten, which can leave muffins dense instead of tender.

Variations to Try

These orange cardamom zucchini muffins are wonderful as written, but they’re also easy to customize.

Try adding:

• White chocolate chunks
• Toasted pistachios
• Dried cranberries
• Chopped pecans
• Turbinado sugar instead of glaze for a crunchy top

How to Store Your Orange Cardamom Zucchini Muffins

Store the muffins in an airtight container at room temperature for up to three days.

For longer storage, refrigerate them for up to a week or freeze the unglazed muffins for up to three months. Thaw overnight at room temperature and glaze just before serving for the freshest flavor.

Frequently Asked Questions

Do you squeeze the water out of zucchini for muffins?

Yes. Lightly squeezing shredded zucchini removes excess moisture while leaving enough behind to keep the muffins tender. Avoid squeezing it completely dry.

Can you freeze zucchini muffins?

Absolutely. Freeze the orange cardamom zucchini muffins without the glaze in a freezer-safe container for up to three months. Add the glaze after thawing for the best texture and appearance.

Can I substitute yellow squash for zucchini?

Yes. Yellow summer squash works almost exactly like zucchini in most baking recipes. Just prepare and measure it the same way you would zucchini.

What does cardamom taste like?

Cardamom has a warm, lightly floral flavor with hints of citrus and spice. It pairs especially well with orange, vanilla, honey, pears, apples, and many summer fruits.

Can I make these ahead of time?

Yes. These muffins stay moist for several days, making them an excellent make-ahead breakfast or brunch option. In fact, many people find the flavors become even more pronounced by the second day.

From Garden to Bakery

One of my favorite things about baking with homegrown produce is discovering combinations that feel just a little unexpected. Zucchini might not seem like an obvious partner for orange and cardamom, but together they create a muffin that’s soft, fragrant, and just the right balance of comforting and fresh.

Whether you’re trying to use up a bumper crop from the garden or simply looking for a new twist on classic zucchini baking, these muffins are proof that simple ingredients can become something truly bakery worthy. I hope they earn a permanent spot in your summer baking rotation.
