Ingredients
  

Ingredients
  • 2 cups all-purpose flour
  • 1/2 cup granulated sugar
  • 1/4 cup brown sugar
  • 2 teaspoons baking powder
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup buttermilk
  • 1/4 cup vegetable oil
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/2 cups fresh blueberries
  • 1/2 cup all-purpose flour (for streusel)
  • 1/4 cup granulated sugar (for streusel)
  • 1/4 cup brown sugar (for streusel)
  • 1 teaspoon ground cinnamon
  • 1/4 cup cold unsalted butter, cubed

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly with butter or cooking spray.
  2. In a small bowl, combine the flour, granulated sugar, brown sugar, and cinnamon for the streusel topping. Add the cold cubed butter and mix until the mixture resembles coarse crumbs. Set aside.
  3. In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, and salt for the muffins.
  4. In another bowl, whisk together the buttermilk, vegetable oil, egg, and vanilla extract until well combined.
  5. Pour the wet ingredients into the dry ingredients and stir gently until just combined. Be careful not to overmix; a few lumps are okay.
  6. Gently fold the fresh blueberries into the batter, ensuring they are evenly distributed.
  7. Divide the batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle the streusel topping generously over each muffin.
  8. Bake in the preheated oven for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
  9. Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. Serve warm or at room temperature.

Notes

Use fresh blueberries for best results. Do not overmix the batter to keep muffins light and fluffy. For taller muffins, fill the muffin cups to the top and bake at 400°F for the first 5 minutes, then reduce to 375°F. Store muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months.
