Ingredients

For the Muffins:
- 2 cups all-purpose flour
- 1/2 cup granulated 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
For the Crumble Topping:
- 1/2 cup all-purpose flour
- 1/4 cup granulated sugar
- 1/4 cup cold butter, cubed
- 1/2 teaspoon ground cinnamon
Step-by-Step Instructions
1. Preheat and Prepare
Preheat your oven to 375°F (190°C). Line a muffin tin with paper liners or grease it lightly with butter.
2. Make the Crumble Topping
In a small bowl, combine the flour, sugar, and cinnamon for the crumble topping. Add the cold cubed butter and use your fingers or a fork to mix until the mixture resembles coarse crumbs. Set aside.
3. Mix the Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
4. Combine the Wet Ingredients
In another bowl, mix the buttermilk, vegetable oil, egg, and vanilla extract until well combined.
5. Combine Wet and Dry Ingredients
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. Fold in Blueberries
Gently fold in the blueberries, ensuring they are evenly distributed throughout the batter.
7. Fill the Muffin Tin
Divide the batter evenly among the muffin cups, filling each about 2/3 full. Sprinkle the crumble topping generously over each muffin.
8. Bake
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
9. Cool and Serve
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.
Expert Tips
- Use Fresh Blueberries: Fresh blueberries work best, but if they’re out of season, frozen blueberries can be used. Just don’t thaw them before adding to the batter.
- Don’t Overmix: Overmixing the batter can result in dense muffins. Stir just until the ingredients are combined.
- Buttermilk Substitute: If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or vinegar to 1 cup of milk and letting it sit for 5 minutes.
- Storage: Store muffins in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months.
