To Die For Blueberry Muffins

My son decided one day that he wanted to make blueberry muffins.  He browsed online and found this recipe from allrecipes.com.  It's so simple to make and yet it's the best muffin we have ever eaten so far - it's moist & not too sweet inside and crunchy on the outside.  So, if my 11 years old son can make it, I am sure you can too, try it.  In case you want it quick, here it is.

Ingredients:
For 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 blue berries/or frozen

For Crumb Topping

• 1/2 cup white sugar
• 1/3 cup all-purpose flour
• 1/4 cup butter, cubed
• 1 1/2 teaspoons ground cinnamon

Directions:

1. Preheat oven to 400 degrees F (200 degrees C). Grease muffin cups or line with muffin liners.
2. 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 enough milk to fill the cup. Mix this with flour mixture. Fold in blueberries. Fill muffin cups right to the top, and sprinkle with crumb topping mixture.
3. To Make Crumb Topping: Mix together 1/2 cup sugar, 1/3 cup flour, 1/4 cup butter, and 1 1/2 teaspoons cinnamon. Mix with fork, and sprinkle over muffins before baking.
4. Bake for 20 to 25 minutes in the preheated oven, or until done.
