Love a muffin that tastes like sunshine? These Lemon Blueberry Streusel Muffins with Lemon Glaze are the kind of bright, bakery-style treat that turns an ordinary morning into something a little sweeter. With a tender crumb, juicy bursts of blueberry, a buttery crumble top, and a vibrant lemon glaze, these muffins are anything but boring.

Whether you need a brunch showstopper or just something comforting to pair with your coffee, these muffins deliver. The streusel topping adds a perfect crunch to the soft, zesty interior, while the glaze brings it all together with a citrusy punch that keeps you reaching for just one more.

Preparation Phase & Tools to Use

To pull off bakery-level muffins at home, a few tools are non-negotiable:

Muffin Tin and Liners: These define the shape and make for easy clean-up. Standard 12-cup muffin pans work great here.
Mixing Bowls (2-3): One for dry ingredients, one for wet, and one for the streusel topping. Keeping these separate until combining ensures a lighter, fluffier texture.
Whisk and Rubber Spatula: A whisk helps integrate your leavening agents and zest smoothly. The spatula is key for folding in blueberries gently to avoid bursting.
Microplane Zester: To get the most fragrant zest from fresh lemons.
Ice Cream Scoop: Helps portion the batter evenly for uniform muffins.
Cooling Rack: Ensures muffins cool evenly without getting soggy bottoms.

Investing in these basic tools not only improves your baking outcome but makes the process smoother and more enjoyable.

Ingredients for the Lemon Blueberry Streusel Muffins with Lemon Glaze

Each ingredient plays a role in creating balance between tartness, sweetness, texture, and aroma:

All-Purpose Flour: The foundation of structure in both the muffins and streusel.
Granulated Sugar: Adds sweetness and tenderizes the muffin crumb.
Brown Sugar: Used in the streusel, it lends a caramelized depth and moist texture.
Baking Powder & Baking Soda: These leaveners give the muffins their lift and softness.
Salt: Just a pinch sharpens the other flavors.
Lemon Zest: Delivers that bright, sunny citrus aroma throughout.
Fresh Blueberries: Juicy, sweet, and slightly tart; they burst with flavor in every bite.
Eggs: Provide structure and help bind everything together.
Buttermilk: Adds moisture and tang that complements the lemon.
Unsalted Butter: Used both melted (for richness in the batter) and cold (for crumbly streusel).
Vanilla Extract: Adds warm undertones that round out the flavor profile.
Powdered Sugar & Lemon Juice: Whisked together for a quick, tangy glaze.

How To Make the Lemon Blueberry Streusel Muffins with Lemon Glaze

Step 1: Prepare the Streusel Topping

In a small bowl, mix flour, brown sugar, and a pinch of salt. Add cold butter cubes and work them in using a fork or your fingers until the mixture resembles coarse crumbs. Chill while preparing the batter.

Step 2: Combine the Dry Ingredients

In a large bowl, whisk together flour, granulated sugar, baking powder, baking soda, and salt. Stir in the lemon zest for even distribution.

Step 3: Mix the Wet Ingredients

In another bowl, whisk together eggs, buttermilk, melted butter, and vanilla extract until well combined.

Step 4: Fold Everything Together

Pour the wet mixture into the dry ingredients and gently mix until just combined. Use a spatula to fold in the blueberries carefully to avoid crushing them.

Step 5: Fill the Muffin Tin

Line your muffin tin and fill each cup about 3/4 full with the batter. Sprinkle a generous amount of streusel on top of each.

Step 6: Bake to Golden Perfection

Bake at 375°F (190°C) for 18-22 minutes until the tops are golden and a toothpick inserted in the center comes out clean. Let them cool slightly in the tin before transferring to a wire rack.

Step 7: Add the Lemon Glaze

Whisk powdered sugar and lemon juice until smooth. Drizzle over the cooled muffins just before serving.

How to Serve and Store Lemon Blueberry Streusel Muffins with Lemon Glaze

These muffins are best served slightly warm or at room temperature. The lemon glaze sets nicely after cooling, making them ideal for brunch spreads, afternoon tea, or quick breakfast grabs. Pair with a creamy latte, hot tea, or chilled lemonade for a refreshing contrast.

To store, place completely cooled muffins in an airtight container. They’ll stay fresh at room temperature for 2 days or refrigerated up to 5. For longer storage, freeze them without the glaze for up to 2 months. Just thaw and glaze before serving.

Frequently Asked Questions

What if I don’t have buttermilk?

You can make a quick substitute by mixing 1 tablespoon of lemon juice or vinegar with 1 cup of milk. Let it sit for 5–10 minutes until slightly curdled.

Can I use frozen blueberries instead of fresh?

Yes, but don’t thaw them before mixing. Toss them in a bit of flour to prevent bleeding into the batter.

How do I keep the streusel from sinking into the muffins?

Make sure the streusel is cold and crumbly before sprinkling it over the batter. This helps it stay on top and crisp up nicely.

Can I make mini muffins instead of standard size?

Definitely! Just reduce the baking time to around 12–14 minutes and keep an eye on them as ovens may vary.

What’s the best way to drizzle the glaze?

Use a spoon or a small zip-top bag with the corner snipped off for more control and neater lines.

Why did my muffins turn out dense?

Overmixing the batter is the usual culprit. Stir just until the flour disappears for a tender crumb.
