Ingredients

Scale
  • 2 cups (240g) all-purpose flour
  • 2 teaspoons baking powder
  • ½ teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • ¾ cup (150g) granulated sugar
  • ½ cup (113g) unsalted butter, melted and cooled
  • ¾ cup (180ml) buttermilk (or regular milk with 1 tbsp vinegar)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • 1 ½ cups (225g) fresh blueberries, washed and patted dry
  • For the streusel topping:
  • ½ cup (60g) all-purpose flour
  • ⅓ cup (65g) brown sugar, packed
  • 4 tablespoons (57g) unsalted butter, cold and cubed
  • ½ teaspoon ground cinnamon
  • Pinch of salt

Instructions

  1. Preheat your oven to 375°F (190°C). Line your muffin tin with paper liners or grease it lightly with butter.
  2. Make the streusel topping: In a small bowl, combine ½ cup flour, ⅓ cup brown sugar, ½ teaspoon cinnamon, and a pinch of salt. Add 4 tablespoons cold, cubed butter. Use a pastry cutter or fingers to mix until coarse crumbs form. Chill in the fridge.
  3. Whisk the dry ingredients: In a large bowl, sift together 2 cups flour, 2 teaspoons baking powder, ½ teaspoon baking soda, ½ teaspoon salt, and 1 teaspoon cinnamon.
  4. Mix wet ingredients: In another bowl, whisk ¾ cup buttermilk, 2 eggs, ½ cup melted butter, ¾ cup sugar, and 1 teaspoon vanilla extract until smooth.
  5. Combine wet and dry ingredients: Pour wet mixture into dry and fold gently with a spatula until just combined; batter will be lumpy.
  6. Fold in blueberries carefully to avoid crushing.
  7. Fill muffin cups about ¾ full with batter.
  8. Sprinkle chilled streusel topping generously over each muffin.
  9. Bake for 20–25 minutes until a toothpick inserted comes out clean and tops are golden brown.
  10. Cool muffins in the tin for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Do not overmix the batter to keep muffins tender. Use cold butter for streusel to achieve a crispy topping. If streusel browns too fast, tent with foil halfway through baking. Pat blueberries dry before folding in to avoid excess moisture. Batter can be mixed the night before; add blueberries just before baking.
