Instructions
- Preheat oven to 400 F degrees and line standard muffin or cupcake pan with paper liners and set aside.

- Reserve ½ cup of blueberries for topping. Place remaining blueberries in a small bowl. Dust blueberries with 1 tablespoon flour and toss them until all blueberries are coated with thin layer of flour and then fold them really gently in the batter.
- Spoon batter into prepared muffin tins, filling maximum 2/3 of each cup and gently tap the pan on the work surface to set. Cover the batter with the remaining blueberries and then cover the blueberries generously with streusel topping.
