intro

Moist, tender low-sugar muffins packed with grated summer veggies, warm cinnamon, and whole grains: a light, not-too-sweet grab-and-go baked treat.

Ingredients

Grated zucchini (squeezed dry) 150 grams (1 packed cup)
Grated carrot 100 grams (2/3 packed cup)
Whole wheat pastry flour 180 grams (1.5 cups)
Coconut sugar 50 grams (1/4 cup)
Baking powder 4 grams (1 teaspoon)
Baking soda 2.5 grams (1/2 teaspoon)
Ground cinnamon 2 grams (1 teaspoon)
Fine sea salt 1 gram (1/4 teaspoon)
Large room-temperature eggs 2 (100 grams total)
Unsweetened applesauce 120 ml (1/2 cup)
Melted unsalted butter (cooled) 30 grams (2 tablespoons)
Pure vanilla extract 5 ml (1 teaspoon)

Steps

1

Prep oven and muffin tin

Preheat your oven to 190°C (375°F) with a rack positioned in the middle. Line a 12-cup standard muffin tin with paper liners, or lightly grease each cup with non-stick spray to prevent sticking.

Step 1
step1:Prep oven and muffin tin
2

Prep and squeeze veggies

Grate unpeeled zucchini and carrot using the small holes of a box grater. Place grated zucchini in a clean cotton kitchen towel, wrap tightly, and squeeze firmly over the sink to remove 60-80 ml of excess liquid (this prevents soggy muffins). Combine squeezed zucchini and grated carrot in a small bowl.

step2:Prep and squeeze veggies
3

Whisk dry ingredients

In a medium mixing bowl, combine whole wheat pastry flour, coconut sugar, baking powder, baking soda, ground cinnamon, and fine sea salt. Whisk vigorously for 30 seconds until all ingredients are evenly distributed, with no clumps of leavening or spice left.

Step 3
step3:Whisk dry ingredients
4

Mix wet ingredient base

In a separate large mixing bowl, crack the room-temperature large eggs and whisk lightly for 10 seconds to blend yolks and whites. Add unsweetened applesauce, cooled melted butter, and pure vanilla extract, then whisk for 20 more seconds until the mixture is smooth and pale golden.

Step 4
step4:Mix wet ingredient base
5

Fold batter and portion

Add the dry ingredient mix and squeezed zucchini-carrot mixture to the wet ingredient bowl. Use a silicone spatula to fold gently for 15-20 seconds, stopping as soon as no dry flour streaks remain (do not overmix, as this creates tough muffins). Divide batter evenly between 12 prepared muffin cups, filling each 2/3 full.

Step 5
step5:Fold batter and portion
6

Bake and cool muffins

Place the filled muffin tin on the middle oven rack and bake for 20-22 minutes, until tops are domed and golden brown, and a toothpick inserted into a center muffin comes out with 1-2 moist crumbs (no wet batter). Let muffins rest in the tin for 5 minutes, then transfer to a wire rack to cool 10 minutes before serving.

Step 6
step6:Bake and cool muffins

Tips

1.Always squeeze all excess moisture from grated zucchini; leftover water will create soggy, sunken muffin centers even with full baking time.
2.Stop folding the batter as soon as dry flour disappears; overmixing develops gluten in whole wheat flour, resulting in tough, dense muffins instead of tender ones.
3.For a tiny crunchy topping without added sugar, sprinkle 1 teaspoon of rolled oats over each muffin batter cup before baking for a toasty, textured top.

Low-Sugar Zucchini Carrot Muffin:Frequently Asked Questions

1.Why do I need to squeeze the grated zucchini dry before adding it to the muffin batter?
Zucchini has extremely high water content, and skipping this step will leave you with soggy, dense, gummy muffins instead of the light, tender crumb we’re aiming for. Grab a clean kitchen towel or cheesecloth, wrap the grated zucchini tightly, and squeeze until almost no liquid drips out—this locks in perfect moisture without watering down the warm cinnamon flavor.
2.Can I substitute the coconut sugar if I don’t have it on hand, or cut the sugar even more?
Absolutely! Swap coconut sugar 1:1 for packed light brown sugar if that’s what you have in your pantry. For an even lower-sugar bake, cut total sweetener by 25% and replace that portion with unsweetened applesauce—you won’t miss the extra sugar thanks to the carrots’ natural sweetness and warm cinnamon spice. Skip straight liquid sweeteners like maple syrup here, as they throw off the batter’s moisture balance without extra flour adjustments.
3.What’s the best way to store these muffins for grab-and-go use, and can I freeze them?
First, let muffins cool completely to avoid trapped condensation that causes sogginess. Store them in an airtight container lined with a paper towel at room temperature for up to 4 days—the towel catches excess surface moisture to keep crumbs tender. For meal prep, wrap individual muffins tightly, stash in a labeled freezer bag, and freeze for up to 3 months; thaw at room temp or reheat 20 seconds in the microwave for a quick snack.

OMG these are SO good! I’ve been searching for a low-sugar muffin recipe that doesn’t taste like cardboard for my weekly meal prep, and this one hits every mark. The zucchini and carrot keep them so moist, I didn’t even miss the extra sugar! Baked a batch Sunday and they held up all week for quick breakfasts on my commute.

So glad these worked for your meal prep, Mandy! Pro tip: if you want to extend their shelf life even more, you can freeze individual muffins and reheat for 30 seconds in the microwave for a fresh-baked taste any time.

My kids devoured these after school yesterday! I was worried they’d turn their noses up at veggies in muffins, but they kept asking for seconds. I added a tiny handful of mini chocolate chips to half the batch for the pickiest eater and he didn’t even notice the difference between the regular and chip versions. Total win for school lunches this week.

Game changer for early gym mornings! I make 2 batches a month, toss them in the freezer, and grab one on my way out the door. 10g of protein if you add a scoop of vanilla protein powder to the dry mix, fyi for anyone tracking macros. No weird aftertaste from the low sugar either, which is my biggest pet peeve with healthy baked goods.

5 days ago

Wait, did you adjust the liquid at all when you added protein powder? I tried that once with another muffin recipe and they turned out super dry!

5 days ago

Super easy recipe! I swapped the eggs for flax eggs and used oat milk instead of dairy, and they turned out perfectly moist. Only giving 4 stars because I wish there was a note about squeezing the excess water out of the zucchini first — my first batch was a little soggy because I skipped that step. Second batch was chef’s kiss though!

3 days ago

Oh thank you for the heads up about squeezing the zucchini! I was just about to mix my batter right now, I totally would’ve forgotten that step too.

2 days ago

Great catch! I’m going to add that note about squeezing shredded zucchini to the recipe steps right now — it holds so much extra moisture, giving it a good squeeze in a paper towel really makes a difference in the final texture. So glad your second batch turned out great!

Brought these to my neighborhood potluck last weekend and they were gone in 10 minutes! Multiple people asked for the recipe, even the neighbors who swear they hate “healthy food.” The warm cinnamon spice is such a nice cozy touch, I can tell I’ll be making these all fall.

Made these for our team break room this week and everyone kept raving about them! It’s so hard to find snacks that work for people watching their sugar intake and people who just want a tasty treat, and these hit the sweet spot (pun intended). Super quick to throw together even on a busy weeknight, which is a huge plus for me.

5 minutes ago

Love that these were a hit with your whole team! They’re such a crowd pleaser because they’re not overly sweet, so they work for almost every dietary preference when you note the veggie base.

I’ve been baking muffins for 60 years and I have to say, this is one of the best veggie muffin recipes I’ve ever tried! I cut the sugar even a little more than the recipe calls for and added a dash of nutmeg, and my book club ladies all begged for the recipe. Nice and tender crumb, no weird gritty texture from whole wheat flour like some recipes.

The nutmeg addition sounds chef’s kiss! I’m making these for my brunch this weekend, I’m definitely going to steal that tip.

So happy a lifelong baker like you approves, Ethel! The nutmeg addition sounds absolutely delicious, I’ll have to test that out for my next batch too.

Wait, is this actually easy for someone who’s never baked anything before? I can barely make toast without burning it, but my girlfriend loves low-sugar zucchini muffins and I want to surprise her for our anniversary. How bad can I mess this up, be honest lol. Giving 5 stars in advance because the comments all look amazing.

30 minutes ago

Dude you’ve got this! I’m terrible at baking and I pulled these off first try, just make sure you shred the veggies fine and don’t overmix the batter and you’ll be golden. She’s gonna love it.

You’ve totally got this, Liam! The recipe is designed to be super forgiving for new bakers — if you run into any snags while you’re making it, just drop a comment here and I’ll help you troubleshoot right away. Good luck, I hope she loves them!

Perfect for dorm baking! I made these in my tiny countertop oven, didn’t even need a fancy mixer, just a bowl and a spoon. Way cheaper and healthier than buying muffins from the campus coffee shop every morning, and they taste way better too. I added some raisins to half the batch and it slapped.

5 days ago

These were really tasty, but mine stuck really bad to the paper liners! Did I do something wrong? I followed the bake time exactly, let them cool for 10 minutes like the recipe said, but half the muffin stayed stuck to the paper when I peeled it. Flavor was 10/10 though, I’ll definitely make them again.

3 days ago

So sorry they stuck to the liners! A quick trick to prevent that is to either spray the inside of the paper liners with a little nonstick spray before adding the batter, or use silicone baking liners which are naturally nonstick. So glad you loved the flavor though!

Does anyone know if these work with gluten free all purpose flour? My youngest has a wheat allergy and we’ve been looking for low-sugar muffin recipes he can take to preschool for snack time. The veggie boost is a huge plus because he refuses to eat carrots or zucchini any other way! Already giving 5 stars because the ingredient list looks perfect.

I made them with a 1:1 gluten free all purpose flour blend last week and they turned out exactly like the regular version! My celiac sister couldn’t even tell the difference, just make sure your blend has xanthan gum in it.

3 days ago

Great question! I’ve tested this recipe with 1:1 gluten free flour and it works beautifully, no adjustments needed. I hope your little one loves them — it’s the best when kids eat their veggies without even noticing!

Tossed two of these in my pack for a day hike last weekend and they were the perfect trail snack! Not too heavy, gave me steady energy instead of the sugar crash I get from regular granola bars, and they didn’t get all squished in my pack the way some muffins do. Will be a staple on all my hikes from now on.

These are perfect for my husband who’s been told to cut back on added sugar for his blood pressure. He has such a sweet tooth I was worried he’d complain, but he says these are his new favorite snack. I love that I can sneak extra veggies into his diet without him noticing, too.

yesterday

Oh that’s such a good idea for my dad too! He’s pre-diabetic and always complains that low-sugar treats taste bland, I can’t wait to make these for him next time I visit.

Made these for my weekend brunch spread and they were such a hit! I topped them with a tiny little drizzle of cream cheese glaze (just a tiny bit, to keep the sugar low) and it was the perfect pairing. The recipe is so easy to customize, I already want to test adding walnuts or shredded apple next time.

2 hours ago

The cream cheese glaze drizzle is genius! I’m making these for a work potluck next week, I’m totally stealing that idea.

30 minutes ago

The cream cheese glaze sounds incredible! Walnuts or shredded apple would be amazing mix-ins too — I love when people put their own creative spin on the recipe, that’s my favorite part of sharing these.

Tried these after seeing Jake’s comment about adding protein powder! I added one scoop of vanilla whey protein and an extra 2 tbsp of almond milk to keep the batter from getting too dry, and they turned out amazing. Way better than the dry protein muffins I’ve been forcing myself to eat after workouts.

just now

So glad the protein powder addition worked out for you! The extra splash of almond milk is such a smart adjustment, I’ll have to note that in the recipe tips for other macro-tracking bakers.

just now

As someone who bakes gluten free 90% of the time, I can confirm these work perfectly with a 1:1 GF flour blend. I also swapped the brown sugar for coconut sugar and it added such a nice warm, caramel-y flavor without adding extra sugar. My toddler ate two in one sitting, which is the highest possible praise in my book.

Made these with my 7 year old daughter last night for her class snack day. She loved helping shred the zucchini and carrots, and she was so proud to tell her classmates she helped make the muffins. The recipe was simple enough for her to help with every step, no fancy techniques or confusing steps. Total dad win.

Aww that’s so sweet! I remember baking with my dad when I was little, those are the best memories. I’m definitely going to make these with my little cousin when she comes to visit next month.
