Ingredients You’ll Need

2 cups all-purpose flour, spooned and leveled: Essential for structure and texture. If desired, you can substitute with a gluten-free blend.
2 teaspoons baking powder: This helps the muffins rise beautifully, creating a soft and fluffy texture.
1/2 teaspoon baking soda: Balances the acidity in the batter for optimal leavening.
1/2 teaspoon kosher salt: Enhances all the flavors in the muffins.
3/4 cup granulated sugar: Adds sweetness. You can reduce this slightly if you prefer a less sweet muffin.
Zest of 2 lemons: Brightens the flavors and adds a refreshing aroma.
1/2 cup unsalted butter, melted and slightly cooled: Provides richness and moisture; for a lighter version, you can replace it with applesauce.
2 large eggs, at room temperature: Helps bind the ingredients and contributes to the structure; bring them to room temperature by leaving them out for about 30 minutes.
1/2 cup plain Greek yogurt, at room temperature: Adds moisture and a slight tang, making the muffins even more tender. Substitute with dairy-free yogurt if needed.
1 teaspoon vanilla extract: A must-have for a lovely aroma and flavor boost.
1 cup shredded zucchini: Adds moisture and nutrition without overpowering the flavors; make sure to squeeze out excess moisture for best results.
1 1/2 cups fresh blueberries: Bursting with flavor; toss some extras on top for added appeal if you like.
1 tablespoon all-purpose flour, for tossing the blueberries: Keeps the blueberries from sinking to the bottom of the muffins.
1 cup confectioner’s sugar: Used for a light glaze that adds sweetness and elegance.
2 to 3 tablespoons fresh lemon juice: Brightens the glaze and brings everything together.

How to Make Lemon Blueberry Zucchini Muffins

Prep the Pan: Preheat your oven to 375°F. Grease a 12-cup muffin pan or line it with paper liners. For taller muffins, consider filling every other muffin cup for extra rise (and use a second pan if necessary).
Mix Dry Ingredients: In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, 1/2 teaspoon baking soda, and 1/2 teaspoon kosher salt. Set this aside; the science of baking relies on mixing dry ingredients accurately!
Rub the Sugar & Lemon Together: In a large bowl, combine 3/4 cup granulated sugar and the zest of 2 lemons. Rub them together with your fingertips until the mixture becomes fragrant and well combined. This step is essential to release all that lemony goodness into the sugar!
Start the Batter: Add 1/2 cup melted and slightly cooled unsalted butter to the lemon-sugar mix, whisking until combined. Next, whisk in 2 large eggs, 1/2 cup plain Greek yogurt, and 1 teaspoon vanilla extract until the mixture is smooth and velvety.
Combine Wet & Dry: Pour the dry ingredients into the wet mixture, stirring just until combined. Avoid overmixing, as that could lead to dense muffins.
Add Zucchini: Gently fold in 1 cup of shredded zucchini until evenly distributed through the batter. Its moisture is your secret weapon for tenderness.
Add Blueberries: Toss 1 1/2 cups fresh blueberries with 1 tablespoon flour, then gently fold them into the batter. This will keep them suspended and perfectly distributed.
Fill Muffin Cups: Divide the batter evenly among the prepared muffin cups, filling them almost to the top for that appealing dome shape.
Bake: Bake for 18 to 24 minutes or until the muffins are golden on top and a toothpick inserted in the center comes out clean or with just a few moist crumbs.
Cool: Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely. This helps them set up and makes them easier to remove.
Glaze: While the muffins cool, whisk together 1 cup confectioner’s sugar and 2 to 3 tablespoons fresh lemon juice until the mixture is smooth. Drizzle over the cooled muffins for a refreshing finishing touch.

Storing & Reheating

To store your Lemon Blueberry Zucchini Muffins, keep them in an airtight container at room temperature for up to three days. If you want to keep them longer, refrigerate them for up to a week. They can also be frozen for up to 3 months; wrap each muffin individually in plastic wrap and place them in a freezer bag. To reheat, pop them in the microwave for about 15-20 seconds or until warm, but be aware the texture may slightly change after freezing. Refresh them with a drizzle of glaze if desired!

Chef’s Helpful Tips

Be sure to fully squeeze the moisture from zucchini; excess liquid can make your muffins soggy.
Use room-temperature ingredients; they combine better and add to the muffins’ fluffiness.
Avoid overmixing the batter to prevent dense muffins—mix until just combined for that perfect light texture.
Want a sweeter muffin? Try adding a sprinkle of brown sugar on top before baking for a caramelized finish.
These muffins can be made ahead of time; just store them in a sealed container until you’re ready to serve.

Recipe FAQs

Can I use frozen blueberries in this recipe?

Absolutely! You can use frozen blueberries; just toss them in flour before adding to the batter to prevent them from sinking and becoming mushy. There’s no need to thaw them beforehand, as they’ll bake beautifully straight from the freezer.

How do I know when the muffins are done baking?

When the tops are golden brown and a toothpick inserted into the center comes out clean or with a few moist crumbs, your muffins are ready! Make sure to check them at the minimum baking time to avoid overcooking.

Can I make this recipe vegan?

Yes, you can make vegan Lemon Blueberry Zucchini Muffins by replacing the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water per egg). Use a plant-based yogurt and replace the butter with melted coconut oil or a vegan butter substitute.

What can I do if my muffins are too dense?

Dense muffins can be a result of overmixing or measuring too much flour. Make sure to spoon and level your flour for accurate measurement and mix until just combined for light, airy muffins. Adjusting the baking powder could also help; check it’s fresh!
