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 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.
- In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, and salt.
- In another bowl, whisk together 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. Be careful not to overmix—the batter should be slightly lumpy.
- Gently fold in the blueberries, ensuring they are evenly distributed throughout the batter.
- Divide the batter evenly among the prepared muffin cups, filling each about 2/3 full. Sprinkle the crumble topping generously 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, then transfer them to a wire rack to cool completely. Serve warm or at room temperature.
Notes
Use fresh or frozen blueberries without thawing. Avoid overmixing the batter to prevent dense muffins. Buttermilk can be substituted with 1 cup milk mixed with 1 tablespoon lemon juice or vinegar.
