Banana Crumb Muffins

Ingredients:
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1/2 teaspoon salt
3/4 teaspoon cinnamon
1/2 teaspoon nutmeg
3 bananas, mashed
3/4 cup white sugar
1 egg, lightly beaten
1 teaspoon vanilla
1/3 cup butter, melted
1/3 cup packed brown sugar
2 tablespoons all-purpose flour
1/8 teaspoon ground cinnamon
1 tablespoon butter
Directions:
1. Preheat oven to 375 degrees F (190 degrees C). Lightly grease 12 muffin cups, or line with muffin papers.
2. In a large bowl, mix together 1 1/2 cups flour, baking soda, baking powder, salt, cinnamon, and nutmeg. In another bowl, beat together bananas, sugar, egg, vanilla, and melted butter. Stir the banana mixture into the flour mixture just until moistened. Spoon batter into prepared muffin cups.
3. In a small bowl, mix together brown sugar, 2 tablespoons flour and cinnamon. Cut in 1 tablespoon butter until mixture resembles coarse cornmeal. Sprinkle topping over muffins.
4. Bake in preheated oven for 18 to 20 minutes, until a toothpick inserted into center of a muffin comes out clean.
* Tip: Double batch to make 4 mini loaves, bake at 350 for 30 minutes. :)
