Blueberry Crumble Muffins
Yields: 12 muffins
Prep time: 15 minutes
Bake time: 18–22 minutes
Ingredients
For the Muffins:
· 2 cups (250g) all-purpose flour
· ½ cup (100g) granulated sugar
· ¼ cup (50g) brown sugar, packed
· 1 tablespoon baking powder
· ½ teaspoon salt
· 2 large eggs, room temperature
· ½ cup (120ml) vegetable oil (or melted butter)
· ½ cup (120ml) buttermilk (or plain yogurt)
· 1 teaspoon vanilla extract
· 1½ cups (225g) fresh or frozen blueberries
· 1 tablespoon flour (for coating blueberries)
For the Crumble Topping:
· ½ cup (65g) all-purpose flour
· ¼ cup (50g) brown sugar, packed
· ¼ cup (50g) granulated sugar
· ½ teaspoon cinnamon
· Pinch of salt
· ¼ cup (60g) cold unsalted butter, cubed
Instructions
- Prepare the Crumble Topping
In a small bowl, whisk together flour, brown sugar, granulated sugar, cinnamon, and salt. Add cold cubed butter. Using your fingers or a pastry blender, work the butter into the dry ingredients until it resembles coarse crumbs with pea-sized butter pieces. Refrigerate while you make the batter.
- Preheat and Prepare
Preheat oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease thoroughly.
- Mix Dry Ingredients
In a large bowl, whisk together flour, granulated sugar, brown sugar, baking powder, and salt.
- Mix Wet Ingredients
In a separate bowl, whisk together eggs, oil, buttermilk, and vanilla extract until smooth.
- Combine Batter
Pour wet ingredients into dry ingredients. Fold gently with a spatula until just barely combined—a few streaks of flour are fine. Overmixing makes tough muffins.
- Coat and Add Blueberries
In a small bowl, toss blueberries with 1 tablespoon flour (this prevents them from sinking to the bottom). Gently fold the coated blueberries into the batter.
- Fill Muffin Cups
Divide batter evenly among 12 muffin cups. Fill each about ¾ full.
- Add Crumble Topping
Sprinkle the chilled crumble topping generously over each muffin, pressing down very lightly so it sticks.
- Bake
Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean (a little blueberry juice is fine) and the tops are golden brown.
- Cool
Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Tips for Perfect Blueberry Crumble Muffins
Problem Fix
Blueberries sink to bottom Toss them in flour before adding to batter
Dry, dense muffins Don’t overmix—mix just until combined
Crumble topping melts into batter Butter must be COLD; chill topping before using
Pale or flat tops Oven temperature may be too low; use 375°F
Muffins stick to liners Let cool 5 minutes before removing
· Fresh vs. frozen blueberries: Both work great. Don’t thaw frozen berries—add them frozen to prevent bleeding.
· Room temperature ingredients: Eggs and buttermilk should be at room temperature for a better rise.
· For taller muffin tops: Fill empty muffin cups halfway with water (if you have empty cups) or bake at 400°F for the first 5 minutes, then reduce to 375°F.
Variations
· Lemon Blueberry: Add 1 tablespoon lemon zest and 1 teaspoon lemon juice to the wet ingredients.
· Almond Blueberry: Replace vanilla with ½ teaspoon almond extract; add ¼ cup sliced almonds to crumble.
· Double Crumble: Double the topping recipe for an extra-thick, crunchy crust.
· Mixed Berry: Use half blueberries, half raspberries or blackberries.
· Blueberry Streusel Coffee Cake Muffins: Add ½ teaspoon nutmeg to the batter and swirl in ¼ cup sour cream.
· Gluten-Free: Use 1:1 gluten-free baking flour (like King Arthur or Bob’s Red Mill).
Storage & Freezing
Room temperature: Store in an airtight container for up to 3 days.
Refrigerator: Not recommended—it dries out muffins. Freeze instead.
Freezer: Wrap each muffin individually in plastic wrap, then place in a freezer bag. Freeze for up to 3 months.
To reheat: Microwave for 20–30 seconds or warm in a 300°F oven for 5 minutes.
