Lemon Blueberry Muffins

The whole house fills with this incredible buttery citrus scent when these muffins are in the oven, and I've had neighbors actually knock on my door asking what I'm baking. My youngest started calling them sunshine muffins because of how bright and happy they make the kitchen feel on rainy mornings.

I brought a batch to my book club last spring and ended up typing out the recipe for three different people before I even left. Something about lemon and blueberries together just makes people feel like they're eating something special, even though it comes together in under an hour.

Ingredients

• 2 cups all-purpose flour: I've learned spooning and leveling rather than scooping directly keeps these from getting dense
• 2 tsp baking powder and 1/2 tsp baking soda: This double leavening combo gives them that nice dome top everyone wants
• 1/2 cup unsalted butter melted: Melting instead of creaming saves time but still gives incredible flavor
• 1 cup granulated sugar: Don't reduce this or you'll lose that tender bakery style texture
• 2 large eggs: Room temperature eggs incorporate so much better into the melted butter mixture
• 1/2 cup Greek yogurt or sour cream: This is the secret ingredient that keeps them moist for days
• 1/4 cup milk: Any percentage works here since the yogurt provides the richness
• Zest of 2 lemons and 2 tbsp juice: Really rub that zest into the sugar first to release all those aromatic oils
• 1 1/2 cups fresh or frozen blueberries: Frozen berries actually work great and don't need thawing
• Streusel topping: 1/2 cup flour 1/3 cup sugar 1/4 tsp salt and 1/4 cup cold cubed butter

Instructions

Get your oven ready:

Preheat to 375°F and line your muffin tin with liners

Mix the dry ingredients:

Whisk flour baking powder baking soda and salt in a medium bowl

Whisk the wet mixture:

Combine melted butter and sugar then beat in eggs yogurt milk lemon zest and juice until smooth

Bring it together:

Fold dry ingredients into the wet just until you don't see dry streaks then gently fold in those blueberries

Fill the muffin cups:

Divide batter evenly using an ice cream scoop for consistent size and fill each about 3/4 full

Make the streusel magic:

Mix flour sugar and salt then work in cold butter with your fingers until you have coarse crumbs

Top and bake:

Sprinkle streusel over each muffin and bake 20 to 22 minutes until a toothpick comes out clean

Cool completely:

Let them sit 5 minutes in the pan then move to a wire rack or that streusel might get soggy

My sister in law asked for the recipe after having one at our brunch and now she makes them every Sunday morning for her family. There's something about that first bite when the streusel crunch meets the soft lemony cake that just makes people pause and smile.

Making Ahead

I often mix the dry ingredients and streusel the night before then just finish the wet ingredients in the morning. The streusel keeps perfectly in a sealed container on the counter and the dry mixture can sit in a covered bowl.

Storage Secrets

These stay moist on the counter for two days in an airtight container but I freeze any leftovers after that individually wrapped in plastic. They thaw at room temperature in about an hour or you can warm them in the microwave for 20 seconds.

Serving Suggestions

These are perfect for brunch alongside a frittata or as an afternoon snack with tea. The buttery streusel makes them feel fancy enough for company but simple enough for a Tuesday morning.

• Split and toast them under the broiler for a minute for extra crunchy edges
• A dollop of lemon curd on a warm muffin is absolutely next level
• These freeze beautifully so double the batch and always have some ready

Save

There's nothing quite like pulling these out of the oven and seeing that golden streusel sparkling on top. Hope they bring as much sunshine to your kitchen as they have to mine.

Recipe FAQs

→ How do you prevent blueberries from sinking?

Toss frozen blueberries in a tablespoon of flour before folding them into the batter, which helps hold them suspended during baking.

→ What makes the streusel topping crunchy?

Cold, cubed butter is mixed with sugar and flour to form coarse crumbs that bake into a buttery, crunchy topping.

→ Can Greek yogurt be substituted in the batter?

Yes, plain Greek yogurt can be replaced with sour cream to maintain moisture and tenderness.

→ What is the best way to mix muffin batter?

Gently fold dry ingredients into wet mixture just until combined to avoid overmixing, which keeps muffins tender.

→ How should the muffins be stored after baking?

Store cooled muffins in an airtight container at room temperature for up to two days or freeze for longer freshness.
