Instructions
- Prepare the streusel topping by combining ½ cup flour, brown 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 ½ cups flour, baking powder, baking soda, and salt in a medium bowl.
- Cream together softened butter and granulated sugar until light and fluffy (2-3 minutes). Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
- Add flour mixture to butter mixture in three additions, alternating with buttermilk, beginning and ending with flour. Mix until just combined - do not overmix. Batter will be thick.
- Toss blueberries with 1 tablespoon flour to coat evenly. Gently fold coated blueberries into the batter.
- 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 even mixing and better rise. Do not overmix batter - mix until just combined. Toss blueberries with flour to prevent sinking. High-low baking temperature creates tall domes. Frozen blueberries work well but do not thaw first.
