Ingredients
Method
- Whisk flour, baking powder, and salt together in a medium bowl. Set aside.
- In a large bowl, whisk melted butter, sugar, and eggs until smooth and slightly pale.
- Whisk in the sour cream, milk, lemon juice, zest, poppy seeds, and extracts until glossy.
- Gently fold the dry ingredients into the wet ingredients using a spatula until only halfway absorbed.
- Add blueberries and continue folding just until no dry flour remains. Do not overmix.
- Cover the bowl and rest the batter at room temperature for exactly 1 hour.
- Preheat oven to 425°F (220°C) and line a 12-cup muffin tin.
- Gently scoop the rested batter into liners, filling them to the very top. Do not stir the batter.
- Bake at 425°F for 7 minutes, then drop the temp to 350°F (175°C) and bake for 13-15 minutes more.
- Whisk glaze ingredients together. Drizzle over muffins while they are still warm.
Notes
For the tallest muffins, try baking only 6 at a time, leaving every other cup empty to improve airflow. Always use fresh lemon juice for the best flavor.
