Banana Crumb Muffins

These are by far the best banana muffins I have ever made.  They are absolutely delicious!  I hope that you like them too.

Banana Crumb Muffins:

Ingredients:
MUFFINS:
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon salt
3-4 medium very ripe bananas, mashed
1/2 cup white sugar
1/4 cup brown sugar
1 egg
1/3 cup canola oil
1 tsp vanilla
1/2 - 1 tsp cinnamon (depending on how much you like cinnamon)
CRUMB TOPPING:
1/3 cup packed brown sugar
2 tablespoons all-purpose flour
1/4 teaspoon ground cinnamon
1 tablespoon butter, barely softened but not melted

Directions:
1.  Preheat oven to 375 degrees.  Grease 12 muffin cups (or use paper liners).
2.  In a bowl combine the flour, baking powder, baking soda, and salt.
3.  In a mixer, beat oil, egg, and sugars until well blended.  Add vanilla, bananas, and cinnamon and mix well. 
4.  Add dry ingredients to the banana mixture and mix just until moistened.  Pour evenly into muffin pan.
5.  For the crumb topping, combine the brown sugar, flour, and cinnamon in a small bowl.  Cut in butter until mixture resembles coarse corn meal or sand.  Sprinkle over the tops of all the muffins.
6.  Bake at 375 for 18-20 minutes or until a toothpick inserted into the center of one of the muffins comes out clean.  Enjoy!
