These Lemon Blueberry Muffins are wonderfully moist and bursting with bright citrus flavor and sweet, juicy blueberries! With a delightful crunchy topping, they make the perfect treat for breakfast or any time you need a little sunshine. I just know you’re going to fall in love with the irresistible combination.

Why These Muffins Are Simply the Best
Making these Lemon Blueberry Muffins brings me so much joy, and eating them is even better. The vibrant mix of lemon and blueberries provides such a refreshing burst of flavor with every bite. Then there’s the lovely crunch from the turbinado sugar on top. That texture contrasts perfectly with the soft, tender crumb of the muffin itself. This recipe uses ingredients you likely already have in your pantry, and I find it incredibly reliable. It consistently produces delicious, homemade muffins without any fuss, making it my go-to recipe time and again.
My Favorite Tips and Tricks
Here are a few pointers I’ve picked up to make your Lemon Blueberry Muffins absolutely perfect every time.
- Mixing Gently: It’s really important not to overmix your batter. Stir the wet and dry ingredients together only until they are just combined. This helps ensure your muffins stay wonderfully soft and airy, not tough.
- Use Fresh Flavors: For the most vibrant taste, I always recommend using fresh lemon zest and fresh blueberries. They make such a difference in brightening up the flavor profile.
- Scoop for Evenness: To make sure all your muffins bake at the same rate and look uniform, try using an ice cream scoop to fill the muffin cups. It helps distribute the batter evenly.
- Don’t Skip the Sugar Topping: Sprinkle turbinado sugar generously over the top of the batter before you put the pan in the oven. It creates that delightful crunchy, sweet crust that I love so much.
- Handling Frozen Berries: If you’re using frozen blueberries instead of fresh, don’t thaw them first. Toss them gently with a tablespoon of flour before adding them to the batter. This little trick helps prevent their color from bleeding throughout your beautiful muffins.

Recipe Tweaks and Possible Changes
One of the great things about baking is how easily you can adapt recipes. Here are some ideas if you need to make a substitution or just want to try something new.
- Make Them Gluten-Free: If you or someone you’re baking for has gluten sensitivities, you can swap out the all-purpose flour for a gluten-free flour blend. Just be sure to use a blend that’s suitable for baking muffins.
- Try a Vegan Version: For a plant-based option, you can replace the egg with a flax egg. For the sour cream, use a plant-based yogurt alternative instead.
- Sugar Swap Options: If you don’t have turbinado sugar, you can use other coarse sugars like demerara sugar. They will give you a similar lovely texture on top. Confectioners sugar works too if you prefer a softer finish.
- Other Citrus Ideas: Lemon is classic, but you could certainly experiment with other citrus fruits. Try swapping the lemon zest and juice for orange or lime zest and juice for a different kind of zesty twist.
Serving and What to Serve With Them
These muffins are truly wonderful served warm right out of the oven. I sometimes enjoy mine with just a little pat of butter melting into the tender crumb. They are also absolutely perfect alongside a comforting cup of tea or coffee. I often include them as part of a special brunch spread. They also make a lovely sweet treat tucked into a packed lunch. For a nice, balanced breakfast or snack, I like pairing them with a creamy yogurt parfait or a refreshing bowl of fresh fruit salad.
How to Store and Reheat
If you happen to have any muffins left (which doesn’t happen often in my house!), here’s how to keep them fresh.
- Storing at Room Temperature: You can keep the muffins in an airtight container on your counter for up to three days. Make sure the container is sealed well to keep them moist.
- Freezing for Later: These muffins freeze beautifully. You can freeze them for up to three months. When you’re ready to enjoy one, just thaw it at room temperature or warm it gently in the microwave.
- Bringing Back the Crunch: To get that wonderful crunchy sugar topping back after storage or freezing, you can pop the muffins into a warm oven at 300°F for just a few minutes. It works wonders.

Questions You Might Have
I get asked a few common questions about making these muffins. Here are the answers.
Yes, you can actually prepare the batter a day before you plan to bake them. Store the batter covered in the refrigerator and then scoop and bake them the next morning.
The best ways to keep your muffins moist are to avoid overbaking them (use that toothpick test!) and always store them in an airtight container once they have cooled completely.
Turbinado sugar has larger crystals compared to granulated sugar. This gives it a wonderful crunchy texture when baked. It also retains a little bit of molasses flavor, adding depth.
Absolutely! Just be sure to add them to the batter while they are still frozen and toss them with a little flour first.
I recommend using full-fat sour cream at room temperature for the best texture and richness in the muffins.

Description
These Lemon Blueberry Muffins are wonderfully moist and bursting with bright citrus flavor and sweet, juicy blueberries! Topped with a delightful crunch, they make the perfect breakfast treat or anytime snack. Enjoy the irresistible combination!
Ingredients
- 2 cups (250 grams) all-purpose flour
- 1 tablespoon (15 grams) baking powder
- ½ teaspoon (3 grams) salt
- 1 large egg (50 grams), room temperature
- 1 cup (200 grams) granulated sugar
- 4 tablespoons (60 grams) unsalted butter, melted and slightly cooled
- 1 ¼ cups (300 grams) sour cream, full-fat, room temperature
- 1 tablespoon (6 grams) fresh lemon zest, from about 1-2 lemons
- ¼ cup (60 ml) fresh lemon juice
- 1 ½ cups (220 grams) fresh blueberries
- Turbinado sugar, for topping (or confectioners sugar)
Instructions
- Heat your oven to 375°F (190°C). Place paper liners into a 12-cup muffin pan.
- Combine the flour, baking powder, and salt in a large bowl. Whisk them together well.
- In a separate bowl, beat the egg and sugar together using a whisk or electric mixer until they are light and fluffy. Stir in the melted butter, sour cream, lemon zest, and lemon juice until everything is combined smoothly.
- Slowly add the dry ingredients to the wet mixture. Mix using a spatula or wooden spoon only until they are just combined. Do not overmix. Gently fold in the blueberries next.
- Spoon the batter evenly into the lined muffin cups. Fill each cup about three-quarters full.
- Sprinkle turbinado sugar generously over the top of each muffin batter-filled cup.
- Bake for around 25 minutes. The muffins are done when a toothpick put into the center of a muffin comes out clean without wet batter attached.
- Let the muffins cool in the pan for 5 minutes. Carefully move them to a wire rack to cool all the way before serving.
Notes
- For the best results and even mixing, make sure all your ingredients are at room temperature before you start combining them.
- If you use frozen blueberries instead of fresh, do not thaw them first. Add them straight into the batter while still frozen. This helps keep the batter from turning blue during mixing and baking.
- Sprinkle the turbinado sugar just before the muffins go into the oven. This helps create a delicious, crunchy topping texture during the baking process.
