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 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 2/3 full.

8. Add the Crumble Topping

Sprinkle the crumble topping generously over each muffin.

9. Bake

Bake in the preheated oven for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean.

10. 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 you can also use frozen ones. 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.
