Instructions
- Prepare the streusel by combining ½ cup flour, brown sugar, granulated sugar, and cinnamon in a small bowl. Add cold cubed butter and work it into the dry ingredients until mixture resembles coarse crumbs. Refrigerate while preparing muffin batter.
- Preheat oven to 425°F (220°C). Line a 12-cup muffin tin with paper liners or grease well. Whisk together 2 cups flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
- In a large bowl, cream together softened butter and sugar until light and fluffy (2-3 minutes). Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
- Alternate adding dry ingredients and buttermilk to butter mixture, beginning and ending with dry ingredients. Mix until just combined - do not overmix.
- Toss blueberries with 1 tablespoon flour to coat evenly. Gently fold coated blueberries into batter using a spatula.
- Divide batter evenly among 12 muffin cups, filling almost to the top. Generously sprinkle chilled streusel topping over each muffin, pressing gently into batter.
- Bake at 425°F for 5 minutes, then reduce oven temperature to 350°F (175°C) without opening oven door. Continue baking for 15-18 minutes, or until toothpick inserted into center comes out clean.
- Allow muffins to cool in pan for 5 minutes before transferring to wire rack to cool completely. Serve warm or at room temperature.
Notes
Use room temperature ingredients for better batter consistency. Do not overmix the batter - a few lumps are fine. The high-low baking technique (425°F then 350°F) creates the bakery-style dome. Coat blueberries with flour to prevent sinking. Frozen blueberries work well but should not be thawed before adding.
