 Blueberry muffins

• 1 ½ cups all-purpose flour

• ¾ cup white sugar

• 2 teaspoons baking powder

• ½ teaspoon salt

• ⅓ cup vegetable oil

• 1 large egg

• ⅓ cup milk, or more as needed

    Directions

    1. Preheat the oven to 400 degrees F (200 degrees C). Grease 8 muffin cups or line with paper liners.

    2. To make the muffins: Whisk flour, sugar, baking powder, and salt together in a large bowl.

    3. Pour oil into a small liquid measuring cup. Add egg and enough milk to reach the 1-cup mark; stir until combined. Pour into flour mixture and mix just until batter is combined. Fold in blueberries; set batter aside.

    4. To make the crumb topping: Combine sugar, flour, butter, and cinnamon in a small bowl. Mix with a fork until crumbly.

    5. Spoon batter into the prepared muffin cups, filling right to the top. Sprinkle with crumb topping.

    6. Bake in the preheated oven until a toothpick inserted in the center of a muffin comes out clean, 20 to 25 minutes.
