Full Ingredients

Cinnamon Streusel Topping

• 3/4 cup (90 g) all-purpose flour
• 1/3 cup (67 g) light brown sugar
• 2 tbsp (25 g) granulated sugar
• 1 tsp ground cinnamon
• 1/8 tsp fine sea salt
• 6 tbsp (85 g) cold unsalted butter, cut into small cubes
• 1–2 tbsp coarse sugar (turbinado or demerara), optional for extra crunch

Muffin Batter

• 2 cups (240 g) all-purpose flour, plus 1 tbsp (8 g) for tossing with berries
• 3/4 cup (150 g) granulated sugar
• 2 tsp baking powder
• 1/4 tsp baking soda
• 1/2 tsp fine sea salt
• 3/4 cup (180 ml) buttermilk, at room temperature
• 1/2 cup (120 ml) vegetable oil (neutral, like canola or sunflower)
• 1/2 cup (120 g) sour cream, at room temperature
• 2 large eggs, at room temperature
• 2 tsp vanilla extract
• 1 tbsp finely grated lemon zest (from about 1 large lemon)
• 1 1/2 cups (225 g) blueberries (fresh or frozen; do not thaw frozen)

Step-by-Step Instructions

Step 1: Prep the oven and pan

Place a rack in the upper-middle of your oven and preheat to 425°F (220°C). Line a 12-cup muffin tin with paper liners. For best height, bring the buttermilk, sour cream, and eggs to room temperature (about 20 minutes on the counter) while you gather ingredients.

Step 2: Make the cinnamon streusel

In a medium bowl, whisk the flour, brown sugar, granulated sugar, cinnamon, and salt. Add the cold butter cubes and cut them in with a pastry cutter or rub between your fingertips until the mixture forms pea-sized, clumpy crumbs. Sprinkle in the coarse sugar if using and toss. Refrigerate the streusel while you make the batter so it stays cold and crumbly.

Step 3: Mix the dry ingredients

In a large bowl, whisk together 2 cups (240 g) flour, baking powder, baking soda, and salt. Remove 1 tbsp (8 g) of this flour and set it aside to toss with the blueberries later—this helps keep them from sinking.

Step 4: Whisk the wet ingredients

In a separate large bowl, whisk the granulated sugar, buttermilk, oil, sour cream, eggs, vanilla, and lemon zest until smooth and well combined.

Step 5: Combine and fold in blueberries

Tip the dry ingredients into the wet and fold with a spatula just until the flour disappears and no dry pockets remain. In a small bowl, toss the blueberries with the reserved 1 tbsp flour, then gently fold them into the batter. The batter will be thick—this is what helps create tall muffin domes.

Step 6: Fill the pan and add streusel

Divide the batter evenly among the 12 liners, filling each to the top. Mound the chilled streusel generously over each portion, pressing it lightly so it adheres. If you like extra crunch, sprinkle with a pinch of coarse sugar.

Step 7: Bake for domed tops

Bake at 425°F (220°C) for 5 minutes, then—without opening the oven—reduce the temperature to 350°F (175°C) and continue baking 14 to 16 minutes, until the tops are golden and a toothpick comes out with a few moist crumbs (or the centers read about 205°F/96°C). Cool in the pan for 5 minutes, then transfer to a wire rack. Let cool another 10 minutes before serving to set the crumb and juices.

Pro Tips

• Weigh ingredients for accuracy; small changes in flour can affect rise and texture.
• A thick batter and full muffin cups are key to tall domes—do not thin the batter.
• Start hot: the 425°F blast lifts the muffins; lowering the heat sets the crumb without drying it out.
• Using frozen blueberries? Fold them in straight from the freezer to minimize purple streaking.
• For even bigger crowns, cover and chill the finished batter 30 minutes, then portion and bake as directed.

Variations

• Lemon-Glazed: Whisk 1 cup (120 g) powdered sugar with 2–3 tbsp fresh lemon juice and a pinch of zest. Drizzle over cooled muffins.
• Almond Streusel: Swap 1/4 cup (25 g) of the streusel flour for finely ground almonds and add 1/4 tsp almond extract to the batter.
• Jumbo Bakery Muffins: Bake in a 6-cup jumbo tin. Start at 425°F for 5 minutes, then 350°F for 18–22 minutes, until golden and done.

Storage & Make-Ahead

Store cooled muffins in an airtight container at room temperature for up to 2 days. For longer storage, freeze on a tray until solid, then bag for up to 3 months; thaw at room temperature or rewarm at 300°F (150°C) for 6–8 minutes to re-crisp the streusel. Streusel can be made up to 3 days ahead and kept refrigerated, or frozen for 1 month. Batter can be mixed, covered, and refrigerated up to 12 hours; portion cold and bake as directed (add 1–2 minutes if needed).
