Instructions
- Prepare the streusel topping 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) and line a 12-cup muffin tin with paper liners. Whisk together 2 cups flour, baking powder, baking soda, and salt in a medium bowl.
- Cream together softened butter and sugar until light and fluffy (2-3 minutes) in a large bowl. Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
- Gradually add dry ingredients to wet ingredients, alternating with buttermilk, beginning and ending with dry ingredients. Mix until just combined - do not overmix.
- Toss fresh blueberries with 1 tablespoon flour to coat evenly, then gently fold into the batter using a spatula.
- Divide batter evenly among 12 muffin cups, filling each nearly to the top. Generously sprinkle chilled streusel topping over each muffin.
- Bake at 425°F for 5 minutes, then reduce temperature to 375°F (190°C) without opening oven door. Continue baking for 15-18 minutes until toothpick inserted comes out clean.
- Cool muffins 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 optimal mixing. Do not overmix batter - lumps are okay. Keep streusel topping chilled until use. Start with high oven temperature for bakery-style dome. For frozen blueberries, use directly from freezer without thawing.
