Banana Crumb Muffins

1 1/2 c all-purpose flour (I used half whole wheat)

1 t baking soda
1 t baking powder
1/2 t salt
3 bananas, mashed
3/4 c white sugar 1 egg, lightly beaten
1/3 c melted butter (or oil)
1/3 c packed brown sugar
2 T flour
1/8 t cinnamon
1 T butter

Preheat oven to 375°. Lightly grease muffin cups or line with papers.

In large bowl, mix together 1 1/2 c flour, baking soda, baking powder and salt.  In another bowl, beat together bananas, sugar, egg and melted butter.  Stir the banana mixture into the flour mixture until just moistened.  Spoon batter into muffin cups.

In a small bowl, mix brown sugar, 2 T flour, and cinnamon.  Cut in 1 T butter until mixture resembles course cornmeal.  Sprinkle topping over muffins.

Bake 18-20 minutes.
