Blueberry Muffins

A few years ago when I had a plethora of blueberries on hand so I did a search on the internet for a great muffin recipe.  This is the one I found, To Die For Blueberry Muffins, and it has been in my recipe box every since.  They look better in person than they do in this picture...and the muffin tops are 'to die for'!

1 1/2 cups flour
¾ cup sugar
½ tsp salt
2 tsp baking powder
1/3 cup vegetable oil
1 egg
1/3 cup milk
1 cup fresh
½ cup sugar
1/3 cup flour
¼ cup butter cubed
1 ½ tsp ground cinnamon

1.        Preheat oven to 400.  Spray muffin pan with Pam.
2.        Combine 1 ½   cups flour, ¾ cup sugar, salt and baking powder.  Place vegetable oil into a 1 cup measuring cup; add the egg and enough milk to fill the cup.  Mix this with flour mixture.  Fold in blueberries. Fill muffin cups right to the top,  (This will make about 9-10 muffins) and sprinkle with crumb topping mixture.
3.        To make crumb topping; mix together ½ cup sugar, 1/3 cup flour, ¼ cup butter and 1 ½ tsp cinnamon.  Mix with a fork.
4.        Bake for 20-22 minutes.
