Why You'll Love This Recipe
About the Ingredients
2 cups (250g) all-purpose flour
The base of your muffin. You can substitute up to 1 cup with whole wheat flour for a heartier texture, but they'll be less tender.
1/2 cup (100g) granulated sugar
Adds sweetness and helps create a tender crumb. You can reduce to 1/3 cup if you prefer less sweet, but don't go lower or the texture may suffer.
1/2 cup (100g) brown sugar, packed
Adds moisture and a hint of molasses flavor. Light or dark both work; dark gives a deeper flavor.
2 teaspoons baking powder
The leavening agent that makes your muffins rise. Make sure it's fresh—test by adding a little to hot water; if it fizzes, it's good.
1/2 teaspoon baking soda
Works with the buttermilk to give a nice lift and helps with browning.
1/2 teaspoon salt
Enhances all the flavors and balances the sweetness.
1/2 cup (1 stick, 113g) unsalted butter, melted and cooled
Use unsalted so you control the salt. You can substitute with coconut oil or vegetable oil, but butter gives the best flavor.
2 large eggs
Room temperature eggs incorporate better. If you're in a hurry, place them in a bowl of warm water for 5 minutes.
1 cup (240ml) buttermilk
Keeps muffins moist and tender. No buttermilk? Add 1 tablespoon lemon juice to regular milk and let sit for 5 minutes.
1 teaspoon vanilla extract
Pure vanilla adds a warm aroma. You can use vanilla bean paste for a more intense flavor.
1 1/2 cups (225g) fresh or frozen blueberries
Fresh are best in season, but frozen work great—do not thaw them before folding, to avoid purple streaks.
Tips & Tricks
Don't overmix the batter
Mix until just combined—a few lumps are okay. Overmixing develops gluten, resulting in tough, dense muffins.
- Use an ice cream scoop to distribute batter evenly: This ensures uniform size and baking time.
- If using frozen blueberries, toss them in a tablespoon of flour before folding in. This prevents them from sinking to the bottom.
- For a taller muffin top, let the batter rest in the muffin tin for 15 minutes before baking.
Pro Tips
Step-by-Step Instructions
1. Preheat and prep
Preheat your oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease with nonstick spray. This high initial temperature gives a quick rise for that beautiful dome.
2. Make the crumble topping
In a small bowl, combine 1/2 cup all-purpose flour, 1/4 cup granulated sugar, 1/4 cup brown sugar, and a pinch of salt. Cut in 1/4 cup (half stick) cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. Set aside.
3. Whisk dry ingredients
In a large bowl, whisk together the flour, baking powder, baking soda, and salt. This ensures even distribution of leaveners, so your muffins rise uniformly.
4. Mix wet ingredients
In a separate bowl, whisk the melted butter, sugars, eggs, buttermilk, and vanilla extract until smooth. The mixture should be well combined but not frothy.
5. Combine wet and dry
Pour the wet mixture into the dry ingredients. Gently fold with a spatula until just moistened—a few streaks of flour are okay. Overmixing leads to tough muffins.
6. Fold in blueberries
Add the blueberries and fold gently with a spatula, just a few turns. If using frozen, don't thaw them first to avoid color bleeding.
7. Fill the muffin cups
Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full. An ice cream scoop makes this easy and mess-free.
8. Top with crumble
Sprinkle the crumble topping generously over each muffin, pressing lightly so it adheres. This will create that irresistible crunchy crust.
9. Bake to perfection
Place in the oven and bake at 425°F (220°C) for 5 minutes, then reduce the temperature to 375°F (190°C) and continue baking for 20-25 minutes, or until the tops are golden brown and a toothpick inserted in the center comes out clean. The initial high heat gives a burst of steam for a tall dome.
10. Cool and enjoy
Allow the muffins to cool in the pan for 5 minutes, then transfer to a wire rack to cool completely. This prevents soggy bottoms and lets the crumble set.
Delicious Variations
Lemon Blueberry
Add the zest of one lemon to the wet ingredients and a tablespoon of lemon juice for a bright, citrusy twist.
Almond Crunch
Substitute the crumble topping with a mixture of sliced almonds, sugar, and a bit of melted butter for a nutty texture.
Streusel with Oats
Add 1/4 cup rolled oats to the crumble mixture for a heartier, more rustic topping.
How to Store Blueberry Crumble Muffins
Refrigerator
Store in an airtight container at room temperature for up to 3 days. For longer storage, keep in the fridge for up to a week.
Freezer
Wrap individually in plastic wrap and place in a freezer bag. Freeze for up to 3 months. Thaw at room temperature or microwave for 30 seconds.
Reheating
For that fresh-baked taste, reheat in a toaster oven or regular oven at 350°F (175°C) for 5-8 minutes. Microwave works, but the crumble may soften.
Frequently Asked Questions
Q: Can I use frozen blueberries?
Yes, you can absolutely use frozen blueberries. Do not thaw them before adding to the batter, otherwise they will bleed and turn your muffins purple. Toss them in a little flour to keep them from sinking.
Q: Why did my muffins sink in the middle?
Muffins sink when the batter is overmixed or when the oven temperature is too low. Overmixing develops gluten, which can cause tunneling and sinking. Also, make sure your oven is properly calibrated and preheated to the correct temperature.
Q: Can I make these muffins gluten-free?
Yes, you can substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. The texture may be slightly more delicate, so handle the batter gently and don't overmix.
Q: How do I keep the crumble from getting soggy?
To keep the crumble crunchy, make sure your butter is cold when you mix it into the flour. Also, bake the muffins thoroughly—underbaked muffins will make the crumble soggy. Store them in an airtight container with a paper towel to absorb excess moisture.
Q: Can I reduce the sugar?
Yes, you can reduce the sugar by up to 1/4 cup total without drastically affecting the texture. However, sugar also helps with browning and moisture, so don't reduce too much or your muffins will be pale and less tender.
