Instructions
- Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly with butter.
- In a large bowl, whisk together the all-purpose 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. Be careful not to overmix; a few lumps are okay.
- Gently fold in the fresh blueberries, ensuring they are evenly distributed throughout the batter.
- If you're adding a crumble topping, mix the chopped nuts, melted butter, and 2 tablespoons of flour in a small bowl until crumbly.
- Divide the batter evenly among the muffin cups, filling each about 3/4 full. Sprinkle the crumble topping over each muffin, if using.
- 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 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 the best flavor and texture. Avoid overmixing the batter to prevent dense muffins. Buttermilk can be substituted with a mixture of lemon juice or vinegar and milk. Store muffins in an airtight container for up to 3 days or freeze for up to 3 months.
