Why You'll Love This Recipe
About the Ingredients
1 ¾ cups (220g) all-purpose flour
Provides structure. You can substitute half with whole wheat for a heartier texture.
1 ½ teaspoons baking powder
Leavening agent that helps muffins rise. Ensure it's fresh for best results.
½ teaspoon baking soda
Balances acidity and aids in browning. Check expiration date.
½ teaspoon salt
Enhances flavors. Use fine sea salt.
½ cup (113g) unsalted butter, melted
Adds richness. You can use coconut oil for a dairy-free version.
¾ cup (150g) granulated sugar
Sweetens and helps create a tender crumb. For less sweetness, reduce to 2/3 cup.
2 large eggs
Bind ingredients and add moisture. Room temperature eggs incorporate better.
½ cup (120ml) buttermilk
Adds tang and tenderness. Make your own by adding 1 tbsp lemon juice to ½ cup milk.
Zest of 2 lemons
Provides intense lemon aroma. Use organic lemons and avoid the white pith.
2 tablespoons fresh lemon juice
Brightens the flavor. Bottled juice works, but fresh is best.
1 ½ cups (225g) fresh or frozen blueberries
Juicy bursts of fruit. If using frozen, do not thaw to avoid bleeding.
For the crumb topping: ½ cup (60g) all-purpose flour, ¼ cup (50g) sugar, ¼ cup (57g) cold butter, ¼ teaspoon cinnamon
The buttery, crunchy topping. You can add a pinch of nutmeg for extra warmth.
Tips & Tricks
Don't overmix the batter
Mix until just combined – a few lumps are fine. Overmixing develops gluten and makes muffins tough.
Use frozen berries without thawing
This prevents them from sinking to the bottom and bleeding color into the batter.
Fill muffin cups completely
For domed tops, fill each cup to the brim. This creates a nice muffin top that holds the crumb topping.
Pro Tips
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease with butter.
2. Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Set aside.
3. Combine Wet Ingredients
In a large bowl, whisk the melted butter and sugar until well combined. Add the eggs one at a time, beating well after each. Stir in the buttermilk, lemon zest, and lemon juice.
4. Combine Wet and Dry
Add the dry ingredients to the wet mixture and stir with a spatula until just moistened. Do not overmix – a few lumps are fine.
5. Fold in Blueberries
Gently fold in the blueberries with a few strokes. If using frozen, do not thaw them first.
6. Make Crumb Topping
In a small bowl, combine the flour, sugar, and cinnamon. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs.
7. Fill Muffin Cups
Spoon the batter into the prepared muffin cups, filling them to the top. Sprinkle the crumb topping evenly over each muffin, pressing lightly.
8. Bake to Perfection
Bake for 18-22 minutes, or until the tops are golden brown and a toothpick inserted into the center comes out with a few moist crumbs. The internal temperature should be around 200°F (93°C).
9. Cool and Serve
Allow the muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature.
Delicious Variations
Add a lemon glaze
Mix 1 cup powdered sugar with 2 tbsp lemon juice and drizzle over cooled muffins.
Swap berries
Use raspberries or chopped strawberries instead of blueberries.
Add a streusel twist
Mix ½ cup chopped nuts (walnuts or pecans) into the crumb topping for extra crunch.
How to Store Lemon Blueberry Muffins with Crumbled Topping
Refrigerator
Store in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week.
Freezer
Wrap individually in plastic wrap and freeze in a zip-top bag for up to 3 months.
Reheating
Reheat in the microwave for 15-20 seconds, or in a 350°F (175°C) oven for 5-7 minutes to refresh the topping.
Frequently Asked Questions
Q: Can I use frozen blueberries?
Yes, you can use frozen blueberries without thawing them. Just fold them into the batter quickly to avoid bleeding.
Q: How do I make these muffins dairy-free?
Substitute the butter with coconut oil or a dairy-free margarine, and use a non-dairy buttermilk like almond milk mixed with lemon juice.
Q: Why did my muffins sink in the middle?
Muffins sink if the oven temperature is too low or if the batter is overmixed. Ensure your oven is preheated and mix just until combined.
Q: Can I make these into mini muffins?
Absolutely! Bake mini muffins for 10-12 minutes, checking for doneness with a toothpick.
Q: How do I get a crunchy crumb topping?
The key is to use cold butter and not overwork the crumb mixture – it should look like coarse sand. Also, don't skimp on the topping.
