What do they taste like?

Putting zucchini in blueberry muffins might sound like a weird move, but anybody who is familiar with zucchini bread knows summer squash can go either sweet or savory. Here, the mild-tasting veggie acts to add moisture and help bind our muffin batter. The fact that it also brings fiber and nutrients to the table? Well, that’s just a pleasant bonus.

With a recipe styled after the beloved classic quick bread, my blueberry zucchini muffins are sweet without being cloying—using a mix of maple syrup and coconut sugar gives them a nice caramel complexity, while whole wheat flour makes them slightly nutty. 

The warming powers of vanilla and cinnamon add a cozy vibe, while bright, tart-sweet pops of blueberries add texture and interest. In short, they’re a masterful mashup of blueberry muffins and zucchini bread. Prepare to be delighted!

Why You’ll Love This Healthy Muffin Recipe

• Quick & Easy – You’ll only need to spend about 10 minutes of prep to whip up the batter, then give ‘em a quick 20-minute spell in the oven. Voila! A week’s worth of breakfast and post-workout snacks is covered. 
• Nutritious & Delicious – As an RDN, I always like to tweak my baked goods recipes to make them healthier than they would be otherwise. For example, swapping in whole wheat pastry flour for all-purpose boosts the fiber and nutrients, while using a mix of greek yogurt and heart-healthy olive oil instead of butter adds protein and a better mix of fats.
• Convenient – Having pre-portioned muffins on hand means I can quickly grab my breakfast or a snack on my way out the door. They also freeze beautifully, making them ideal for any meal-prepping mavens out there.

Ingredients Needed

• Zucchini & Blueberries – The stars of our muffin recipe! Note that you’ll want to buy whole zucchini so you can shred it, but feel free to use fresh or frozen berries.
• Plain Greek Yogurt – I used full-fat yogurt, but you’re welcome to use low-fat or nonfat if you like.
• Large Eggs – Whenever a recipe calls for more than one egg, size does matter. In total, you’ll need a scant ½ cup.
• Avocado Oil – Using oil instead of butter makes muffins light and fluffy. You can’t get a better nutritional profile than avocado oil, and the neutral flavor makes it perfect for a sweet recipe like this.
• Vanilla Extract – Make sure to use pure vanilla extract for the best results.
• Maple Syrup – Getting 100% pure maple syrup is even more important that getting real vanilla. Don’t be fooled by the colored corn syrup blends masquerading as the good stuff!
• Coconut Sugar – I love using this less-refined sugar option in place of white sugar whenever I can. It has a lower glycemic index (so it doesn’t affect your blood sugar as much) and contains trace minerals.
• Whole Wheat Pastry Flour – I’ll let you in on a little secret: swapping in this light whole grain flour for AP will work in almost all recipes if you add a little extra liquid. And make no mistake—despite the pale coloring, this is still considered 100% whole grain goodness.
• Cinnamon – This warming spice plays a little trick on your tongue, adding sweetness without adding sugar. It’s also a natural pairing for our zucchini blueberry muffins.
• Baking Powder & Baking Soda – You’ll need both leaveners for the batter to properly poof up in the oven. Don’t try to use them interchangeably!

Substitutions

Missing a key ingredient? Don’t fret. There’s likely a good substitution in your pantry:

• Zucchini – Any variety of summer squash including yellow squash, patty pan, and zephyr can be used instead.
• Blueberries – Try swapping in dried fruit (e.g. raisins), toasted nuts, or even chocolate chips for a fun twist. You can also omit them if you prefer straight-up zucchini muffins!
• Greek Yogurt -If you only have sweetened greek yogurt, make sure the flavor is compatible (e.g. vanilla, blueberry) and reduce the added coconut sugar. Other thick yogurt varieties like skyr or labna can be used interchangeably with plain. And don’t forget you can strain regular yogurt to make Greek yogurt! Otherwise, soft silken tofu is a good alternative.
• Eggs – I haven’t tried it, but I have a feeling these muffins would turn out just fine if you swapped in vegan liquid eggs or flax eggs. Here are some other good egg substitutes to consider.
• Avocado Oil – Canola oil is more affordable than avocado oil and still has a pretty heart-healthy reputation. If you’re on a tight budget, don’t hesitate to make the swap.
• Vanilla Extract – You can use an equal amount of vanilla paste or vanilla powder. You can also experiment with other complimentary flavoring extracts like almond.
• Maple Syrup – Other liquid sweeteners like honey or agave nectar are good alternatives. Note that agave is more neutrally flavored, so consider adding ⅛ teaspoon of maple extract for a bit more complexity.
• Coconut Sugar – Other varieties of less-refined sugars like grated piloncillo or jaggery will work. You can also trade in cane sugar.
• Whole Wheat Pastry Flour – A 50/50 split of all-purpose flour and regular whole wheat flour is a good compromise in terms of consistency and nutrition.
• Cinnamon – Feel free to omit it, or swap in another warming spice like ginger or cardamom.

How To Make Blueberry Zucchini Muffins

This easy breakfast recipe comes together in just a few steps:

Step 1: Dry Ingredients. Whisk together the flour, cinnamon, leaveners, and salt in a mixing bowl. Set aside.  

Step 2: Grate & Squeeze the zucchini, placing the shreds in a clean dish towel (it might stain a bit green) or sturdy paper towels. Remove as much liquid as you can, then measure it. Set it aside.

Step 3: Wet Ingredients. In a separate mixing bowl, whisk together the eggs, yogurt, maple syrup, coconut sugar, and vanilla. 

Step 4: Mix. Whisk the dry ingredients into the wet ingredients until incorporated. It will feel tight and look dry and clumpy—that’s okay. Don’t overmix.

Step 5: Fold the zucchini and blueberries into the muffin batter.

Step 6: Bake. Divvy the batter into a 12-well standard muffin tin lined with cupcake liners and bake at 350ºF for 19-21 minutes, or until a toothpick comes out clean. Allow to cool in the tin for 5-10 minutes, then remove to a wire rack to continue cooling. Enjoy!

Optional Variations & Dietary Adjustments

• Reduced-Sugar – Feel free to swap in your favorite cup-for-cup sugar alternative (e.g. monkfruit) in place of the coconut sugar. This will reduce the glycemic impact and lower the total calories, but since maple syrup is in the mix, they won’t be sugar-free.
• Vegan – You can use your favorite plant-based greek yogurt alternative and swap in flax eggs or the egg alternative of your choice. (Note that some egg swaps work better than others in baking, so choose wisely.)
• Gluten-Free – I haven’t tried it, but a cup-for-cup gluten-free flour blend (preferably one with xanthan gum) might work well here. You can also experiment with gluten-free single flours (e.g. buckwheat), but there’s a chance they’ll end up kind of dense. Note that many gluten-free flours are “thirstier” than wheat, so give the batter a 30 minute rest before baking to prevent grittiness.

Serving Suggestions

I love to enjoy a gently warmed blueberry zucchini muffin with one of my favorite coffee recipes and a good book before the kids get up—it’s a nice little moment of “me time!” If I’m feeling indulgent, I might split the muffin open and add a pat of grass-fed butter or a swipe of nut butter, but it’s perfectly yummy without. 

If you’re someone who needs a bit more protein to feel full, try pairing your muffin with some greek yogurt, a hard-boiled egg, or even by adding protein powder in your coffee. These tasty little handheld snacks are also great for refueling after a workout, and my kindergartener loves them as her after-school treat before homework!

• Room Temperature – Allow the zucchini blueberry muffins to cool completely to room temperature before transferring them to an airtight container—this will prevent condensation from forming and making them soggy. They’ll keep well at room temp for up to 5 days.
• Freezing – For longer storage, individually wrap the muffins in plastic wrap, then transfer to a freezer bag and remove as much air as possible—this will ward off freezer burn. They’ll keep well for up to a month. (You can keep them longer than that; the texture might suffer a bit, though.)
• Reheating – You can defrost frozen muffins at room temp (they’re great for packing into lunches), or pop them in a toaster oven at 200ºF for about 6 minutes.

Recipe Success Tips

• Make sure to measure your zucchini after squeezing out all the liquid—you’d be surprised at how much it’ll shrink down!
• While you’re welcome to use a food processor to make short work of shredding the zucchini, I find the large holes of a box grater get the job done almost as quickly with way less stuff to clean up.
• If you’re using frozen blueberries, don’t defrost them first—they’ll turn your batter blue.
• Make sure you’re measuring your flour properly using the fluff, spoon, and sweep technique.
