Ingredients

Scale
  • 1 ¾ cups (220g) all-purpose flour
  • ¾ cup (150g) granulated sugar
  • ½ teaspoon salt
  • 2 teaspoons baking powder
  • ⅓ cup (80ml) vegetable oil (or melted unsalted butter)
  • 1 large egg, room temperature
  • ⅓ cup (80ml) whole milk (or dairy-free milk)
  • 1 teaspoon pure vanilla extract
  • 1 cup (150g) fresh or frozen blueberries
  • For the Streusel Crumble:
  • ½ cup (60g) all-purpose flour
  • ⅓ cup (65g) packed light brown sugar
  • ¼ cup (57g) unsalted butter, cold and cubed
  • ½ teaspoon ground cinnamon

Instructions

  1. Preheat the oven to 375°F (190°C). Line a 12-cup muffin tin with liners or lightly grease it.
  2. In a large bowl, whisk together flour, sugar, salt, and baking powder until well combined.
  3. In a separate bowl, whisk together vegetable oil, egg, milk, and vanilla extract until smooth.
  4. Pour the wet ingredients into the dry ingredients and gently fold with a rubber spatula just until combined. Batter should be thick and slightly lumpy; do not overmix.
  5. Carefully fold in the blueberries, being gentle to avoid bursting them.
  6. In a small bowl, combine flour, brown sugar, and cinnamon for the streusel. Cut in cold cubed butter until mixture resembles coarse crumbs.
  7. Spoon batter evenly into muffin cups, filling each about ¾ full. Generously sprinkle streusel topping over each muffin.
  8. Bake for 20-25 minutes or until a toothpick inserted in the center comes out clean and tops are golden with a crunchy crumble.
  9. Let muffins cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.

Notes

Do not overmix the batter to keep muffins tender. Keep butter cold when making streusel for best crumbly texture. If streusel browns too quickly, cover muffins loosely with foil halfway through baking. Use frozen blueberries straight from freezer, tossed in flour to prevent sinking.
