Banana Crumb Muffins

This is a recipe that I found online this summer while visiting a friend in St. George.  She was gone to a dentist appointment and I wanted to use some bananas that I had brought with me.  I searched online and found this and it is a new favorite. 

Here's what you need:

2 cups flour
1 1/2 tsp baking soda
1 1/2 tsp baking powder
3/4 tsp salt
1/8 tsp cinnamon
4 mashed bananas
1 cup white sugar (I use about 2/3 cup)
2 medium eggs, lightly beaten
1/3 cup butter, melted (I use about 1/4 cup black bean puree, then top it off with the butter)

Crumb topping:
1/3 cup brown sugar
2 1/2 T flour
1/8 tsp cinnamon
1 T butter

Preheat oven to 375.  Lightly grease muffin pan.

Mix together flour, baking soda, baking powder, cinnamon, and salt.  Add all at once: mashed bananas, sugar, eggs, and melted butter/puree.  Mix just until moistened.  Spoon into 12 muffin cups.

In a small bowl, mix together brown sugar, 2 T flour, and cinnamon. Cut in 1 T butter until it resembles coarse cornmeal. Sprinkle over muffin batter and bake at 375 for 16-18 min.
