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
  • 1/3 cup vegetable oil
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/2 cups fresh blueberries
  • 1/2 cup all-purpose flour (for crumble topping)
  • 1/4 cup granulated sugar (for crumble topping)
  • 1/4 cup brown sugar (for crumble topping)
  • 1/2 teaspoon ground cinnamon
  • 1/4 cup cold 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.
  2. In a small bowl, combine the flour, granulated sugar, brown sugar, and cinnamon for the crumble 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 smooth.
  5. Pour the wet ingredients into the dry ingredients and stir gently until just combined. Be careful not to overmix—lumps are okay!
  6. Gently fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.
  7. Divide the batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle a generous amount of the crumble topping 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 tin 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, but frozen can be used without thawing. Avoid overmixing the batter to keep muffins fluffy. Buttermilk can be substituted with milk and lemon juice or vinegar.
