Instructions
- Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly with butter or cooking spray.
- In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, and salt.
- In another bowl, mix the buttermilk, vegetable oil, egg, and vanilla extract until well combined.
- Pour the wet ingredients into the dry ingredients and stir gently until just combined. Fold in the blueberries.
- In a small bowl, combine the flour, granulated sugar, brown sugar, and cinnamon for the crumble topping. Add the cold butter cubes and mix until the mixture resembles coarse crumbs.
- Divide the muffin batter evenly among the prepared muffin cups, filling each about 2/3 full. Sprinkle a generous amount of the crumble topping over each muffin.
- Bake in the preheated oven for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
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 a mixture of milk and lemon juice or vinegar.
