Blueberry Streusel Muffins
Bakery muffins get their tall, domed tops and crumbly streusel from a couple of specific techniques, and this recipe borrows both. A hot oven start gives the batter a quick lift, and a proper streusel — made with cold butter, not melted — sits on top for crunch against the moist crumb underneath.
Juicy blueberries throughout mean no bite is ever plain, and the whole thing comes together in one bowl for the batter, no mixer required.

Why This Recipe Works
Baking at a higher initial temperature (400°F) gives the batter a fast burst of oven spring before the crumb structure sets, which is exactly what creates that tall, domed bakery-style top. Using cold, cubed butter in the streusel (rather than melted) keeps it clumpy rather than smooth, so it bakes into distinct crumbly pieces instead of melting into the muffin top.
Ingredients
For the muffins:
- 1¾ cups (220g) all-purpose flour
- 1 cup (200g) granulated sugar
- 2 teaspoons baking powder

- 1½ cups fresh or frozen blueberries
For the streusel:
- ¼ cup (30g) all-purpose flour
- ⅓ cup (65g) brown sugar

Blueberry Streusel Muffins
- 1¾ cups (220g) flour
- 1 cup (200g) sugar
- 2 large eggs
- ½ cup oil
- 1½ cups blueberries
- ¼ cup (56g) cold butter, for streusel
- Mix streusel: ¼ cup flour, brown sugar, cinnamon, cut in cold butter until crumbly. Set aside.
- Whisk remaining flour, sugar, baking powder, salt. Whisk eggs, oil, milk, vanilla separately, combine, fold in blueberries.
- Divide among 12 lined muffin cups. Sprinkle streusel on top.
- Bake at 400°F (200°C) for 18-20 minutes until a toothpick comes out clean.
- Cool in the pan 5 minutes before transferring to a rack.
Step-by-Step
Step 1: Make the Streusel
Mix the flour, brown sugar, and cinnamon together. Cut in the cold, cubed butter with your fingers or a pastry cutter until it forms clumpy crumbs. Set aside.
Step 2: Mix the Batter
Whisk the flour, sugar, baking powder, and salt together in a large bowl. In a separate bowl, whisk the eggs, oil, milk, and vanilla. Pour the wet ingredients into the dry and stir just until combined. Gently fold in the blueberries.
Step 3: Fill the Muffin Tin
Divide the batter evenly among 12 lined muffin cups, filling each about ¾ full. Sprinkle the streusel evenly over the tops.
Step 4: Bake
Bake at 400°F (200°C) for 18 to 20 minutes, until a toothpick inserted in the center comes out clean.
Step 5: Cool and Serve
Cool in the pan for 5 minutes, then transfer to a wire rack to cool slightly more before serving.
Pro Tips
- Toss blueberries in flour first: this small step keeps them from all sinking to the bottom during baking.
- Don't overmix: stir just until the flour disappears — a lumpy batter makes for a lighter muffin.
- Keep streusel butter cold: this is what gives it a crumbly, distinct texture instead of melting flat.
- Fill cups generously: a fuller cup helps create that classic tall, domed muffin top.
Storage & Make-Ahead
Store in an airtight container at room temperature for up to 3 days, or refrigerate for up to a week. These muffins also freeze well for up to 3 months — wrap individually and thaw at room temperature or microwave briefly to warm.
Variations & Substitutions
- Lemon blueberry version: add 1 tablespoon lemon zest to the batter for a bright citrus note.
- Mixed berry muffins: use a combination of blueberries and raspberries.
- Whole wheat swap: substitute up to half the flour with whole wheat flour for a heartier texture.
- Glazed version: drizzle a simple powdered sugar glaze over cooled muffins instead of, or in addition to, the streusel.
