To Die For Blueberry Muffins

Recipe from: AllRecipes.com- http://allrecipes.com/recipe/to-die-for-blueberry-muffins/detail.aspx

Ingredients

• 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
• 1/2 tsp vanilla
• 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

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. Add vanilla. 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.

Notes:

~I used frozen blueberries, which I de-thawed before mixing in (I didn't de-thaw them so much that there was tons of liquid after).

~I used a different crumb topping, based off of reviews:

"try this fail proof one I use that has less butter (perfect amount if doubling recipe): 2/3C brown sugar, 1/4C flour, 1/4 tsp cinnamon, 2T butter. Use fork to mix and has nice coarse texture."

I halved this, and still had A TON.  I am just saving it for now, for next time I make muffins of banana bread of something.
