Ingredients

For the Muffins:
- 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
For the Crumble Topping:
- 1/2 cup all-purpose flour
- 1/4 cup granulated sugar
- 1/4 cup brown sugar
- 1/2 teaspoon ground cinnamon
- 1/4 cup cold unsalted butter, cubed
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 or cooking spray.
2. Make the Crumble Topping
In a small bowl, combine the flour, granulated sugar, brown 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, granulated sugar, brown 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 fresh blueberries, ensuring they are evenly distributed throughout the batter.
7. Fill the Muffin Tin
Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full. Sprinkle the crumble topping generously over each muffin.
8. Bake
Bake in the preheated oven for 18-22 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 pan 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 for this recipe, but you can also use frozen blueberries. If using frozen, do not thaw them before adding to the batter.
- Do Not 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.
For a delightful twist, try adding a handful of chopped nuts to the crumble topping for extra crunch. You might also enjoy pairing these muffins with a refreshing Summer Fruit Salad for a complete breakfast or brunch spread.
FAQ
Can I use frozen blueberries instead of fresh?
Yes, you can use frozen blueberries. Just make sure not to thaw them before adding to the batter to prevent the color from bleeding.
How do I get a tall dome on my muffins?
To achieve a tall dome, make sure your oven is fully preheated before baking. Also, filling the muffin cups 3/4 full and baking at a slightly higher temperature (375°F) helps create that bakery-style dome.
Can I make these muffins ahead of time?
Absolutely! These muffins can be made ahead and stored in an airtight container. They also freeze well, so you can enjoy them anytime.
