Packed with hidden veggies, juicy blueberries, and whole grains — these blueberry zucchini muffins are the muffin I make every time blueberry season hits and the garden zucchini situation gets out of hand — wholesome enough for my toddler, delicious enough that I'm sneaking a second one too.

I'll be honest — the zucchini in these muffins started as a stealth operation. My toddler treats vegetables like a genuine moral offense. Since the little guy can't survive on Z Bars alone, I needed a workaround. These blueberry zucchini muffins were the solution. He eats two and asks for more, completely unaware there's a vegetable involved. I've never told him, and you can bet I don't plan to anytime soon.
These healthy zucchini muffins are made with whole wheat pastry flour, unsweetened applesauce, Greek yogurt, and a generous two cups of shredded zucchini — which means they're genuinely good. But that's not all: the blueberries burst in the oven, creating pockets of jammy sweetness; the cinnamon and allspice give them a warm, bakery-style flavor; and the turbinado sugar on top adds a crunch that makes them look like they came from an actual bakery.
As a marathon runner, I'm also a fan of the fact that blueberries are one of the best anti-inflammatory foods you can eat — they're great for post-run recovery and are loaded with antioxidants. We bake a double batch on Sunday, and are set for the week.

How to Prep the Zucchini
Do you need to squeeze zucchini for muffins? Yes, don't skip it. Zucchini holds a surprising amount of water. If you fold it in unsqueezed, that water releases into the batter as the muffins bake — making them gummy and dense. Wrap shredded zucchini in a clean kitchen towel or a few layers of paper towels and squeeze firmly. You may be surprised how much water comes out.

How to Shred |
Use the large holes on a box grater or a food processor with a shredding attachment. No peeling needed — the skin is thin and melts into the batter, leaving only pretty green flecks. |
|
How Much |
2 cups shredded = about 1½–2 medium zucchinis (depending on size) |
|
Measure, Then Squeeze |
Shred and measure 2 cups first, then squeeze out the moisture before adding to the batter. |
|
Using Pre-Shredded |
You can use store-bought, pre-shredded zucchini, but it tends to be drier and thicker. I recommend freshly shredded whenever possible. |
The Applesauce & Yogurt Combo
These two ingredients are the reason these healthy blueberry zucchini muffins are lighter and more wholesome than most muffin recipes — without sacrificing any moisture.
- Applesauce replaces part of the oil, adding moisture and natural sweetness while reducing the overall fat. Always use unsweetened to control the sweetness.
- Greek yogurt adds tenderness, a subtle tang, and a small protein boost. Plain or vanilla both work. Any fat percentage works, but full-fat gives the richest result.
Together with the zucchini's natural moisture, they create a muffin that stays tender for days — which is exactly what you need for a whole week of grab-and-go breakfasts.
Important Ingredients and Substitutions
Avocado oil — Neutral flavor, high in healthy fats. Canola, grapeseed, or melted coconut oil all substitute 1:1.
Whole wheat pastry flour — Adds whole grain nutrition and a slightly nutty depth without making the muffins dense. All-purpose flour substitutes 1:1 for a lighter texture.
Cane sugar — The recipe uses 1 cup of cane sugar, or you can use ½ cup each white and brown sugar. Brown sugar adds a warmer, more molasses-forward flavor.
Blueberries — Fresh or frozen both work. If using frozen, do not thaw first — fold them in straight from the freezer to prevent the batter from turning purple.
Tossing blueberries in flour — Don't skip this step. It keeps the blueberries suspended in the batter instead of sinking to the bottom.
Turbinado sugar — Optional but highly recommended. That sparkly, crunchy top is what makes these look bakery-made.
Recipe Variations
Once you've got the base recipe down, it can be fun to experiment with your favorite twist:
- Lemon Blueberry — Add 1 tablespoon of fresh lemon zest to the wet ingredients and a squeeze of lemon juice. The brightness plays beautifully against the blueberries and warm spices.
- Chocolate Chip — Fold ½ cup of mini chocolate chips into the batter along with the blueberries. Particularly popular with toddlers (ask me how I know).
- Mixed Berry — Substitute half the blueberries with raspberries or blackberries for a more complex berry flavor.
- Gluten-Free — Substitute a 1:1 GF flour blend, let the batter rest for 30 minutes before baking, and cool completely before enjoying.
- Dairy-Free — Use coconut yogurt instead of Greek yogurt and non-dairy milk. The texture stays moist and tender.
- Mini Muffins — Use a mini muffin tin and reduce the bake time to 10–12 minutes. Perfect for toddler snacks and little hands.
How to Make Blueberry Zucchini Muffins
For the complete recipe and measurements, scroll to the recipe card at the bottom of this post.
Prepare: Step 1: Preheat the oven to 400°F. Line a muffin tin with 18 muffin liners.
Step 1: In a large bowl, whisk together the oil, Greek yogurt, applesauce, vanilla, eggs, milk, and sugar until well combined.
Step 2: Place the shredded zucchini in a clean tea towel or paper towels and squeeze firmly to remove moisture.
Step 3: Fold the squeezed zucchini into the wet ingredients.
Step 4: Add the flour, salt, baking powder, baking soda, cinnamon, and allspice. Fold in until just combined — do not overmix.
Step 5: In a small bowl, toss the blueberries with 1½ tablespoons of flour until coated. Fold the floured blueberries into the batter.
Step 6: Divide the batter evenly among the muffin cups. Sprinkle each muffin with 1 teaspoon of turbinado sugar if desired.
Step 7: Bake at 400°F for 5 minutes. Reduce to 350°F and bake an additional 13–15 minutes until a toothpick inserted in the center comes out clean.
Chelsea's Recipe Pro-Tips
- Start at high heat — Baking at 400°F for the first 5 minutes gives you that beautiful domed muffin top. Reducing to 350°F finishes them through without overbrowning.
- Don't overmix — Once the flour goes in, fold gently until just combined. A few streaks of flour are fine. Overmixing makes muffins tough and dense.
- Flour the blueberries — Tossing in 1½ tablespoons of flour before folding in keeps them suspended in the batter instead of sinking. Don't skip it.
- Frozen blueberries — don't thaw — Fold them in straight from frozen. Thawed berries bleed into the batter and can make it turn an unfortunate shade of purple.
- Use room temperature eggs — They incorporate more smoothly into the batter. Set them out 20–30 minutes before baking or pop in warm water for 5 minutes.
High Altitude Directions
Tested and developed in Fort Collins, CO at approximately 5,000 feet — one of the only blueberry zucchini muffin recipes with real high-altitude testing behind it.
At 5,000+ feet:
- Increase flour to 2¼ cups (280g) for more structure
- Decrease baking powder and baking soda to ½ teaspoon each to prevent over-rising
- Reduce sugar to ¾ cup to avoid gummy centers
- After the initial 5-minute bake at 400°F, reduce temperature to 365°F instead of 350°F
At sea level: Follow the recipe as written. No adjustments needed.
Storage Directions
- Storing: Keep in an airtight container at room temperature for up to 3 days, or refrigerate for up to 5 days.
- Freezer: Cool completely, then freeze in a freezer-safe container or bag for up to 3 months. Thaw at room temperature for 30 minutes or microwave for 20–30 seconds.
Serving Suggestions
These blueberry zucchini muffins are perfect on their own, but they pair beautifully with a Blueberry Spinach Smoothie or a Green Date Smoothie for a quick, antioxidant-packed breakfast before a long run.
For the grown-ups, pair muffins with a Protein Coffee for extra staying power. Or serve them alongside Scrambled Eggs with Cottage Cheese for a protein-forward plate that keeps everyone fueled well into the day.
Zucchini Blueberry Muffin FAQs
Certainly. Fold them in straight from frozen without thawing. Thawed blueberries release too much liquid and can turn the batter purple.
Yes, cool them completely, then freeze in a freezer-safe bag for up to 3 months. Thaw at room temperature for 30 minutes or microwave for 20–30 seconds.
Yes, shred the zucchini, measure out 2 cups, then wrap it in a clean kitchen towel and squeeze out the moisture before adding to the batter. This is the single most important step for avoiding gummy muffins.
This is almost always caused by not squeezing the zucchini thoroughly, underbaking, or overmixing. Give it a good squeeze, check with a toothpick in the very center (not the edges), and fold in the dry ingredients gently until just combined.
Yes, pour the batter into a greased 9x5-inch loaf pan and bake at 350°F for 55–65 minutes, starting to check at 55 minutes with a toothpick.
Yep! My 3-year-old loves these muffins. They are made with wholesome, toddler-friendly ingredients. The zucchini is completely undetectable, and the blueberries add natural sweetness. If preferred, skip the turbinado sugar topping for very young kids.
A toothpick inserted in the center should come out completely clean. The tops should be golden and spring back lightly when pressed. Start checking at 13 minutes after lowering the temperature.
