To Die For Blueberry Muffins

1 1/2 cups all-purpose flour

3/4 cup white sugar

1/2 teaspoon salt

2 teaspoons baking powder

1/3 cup vegetable oil

1 egg

1/3 cup milk

1 cup fresh blueberries

1/2 cup white sugar

1/3 cup all-purpose flour

1/4 cup butter, cubed

1 1/2 teaspoons ground cinnamon

Preheat oven to 400 degrees F. Grease muffin cups or line with muffin liners.

Combine 1 1/2 cups flour, 3/4 cup sugar, salt and baking powder. Place vegetable oil into a 1 cup measuring cup; add the egg and beat to incorporate. Add enough milk to fill the cup. Mix this with flour mixture. Fold in blueberries. Fill muffin cups 2/3 full or right to the top., and sprinkle with crumb topping mixture.

To Make Crumb Topping; Mix together the 1/2 cup sugar, 1/3 cup flour, 1/4 cup butter, and 1 1/2 teaspoons cinnamon. Mix with a fork or your fingers until butter is incorporated and sprinkle over muffins before baking. I had enough topping for 24 muffins.

Bake for 20 to 25 minutes in the preheated oven, or until done.
