Banana Streusel Muffins

Yum, overripe bananas-gross.
I needed to do something with them soon, so I tried this recipe for our family recipe swap this month. I think they turned out pretty good, if anything, they could actually have a little more banana flavor. Here is where I got the recipe-you can check out other people's reviews here too if you want.

INGREDIENTS
2 cups all-purpose flour
1 cup sugar
1 teaspoon baking powder
1/2 teaspoon salt
1/2 teaspoon baking soda
1/4 teaspoon ground cinnamon
2 eggs
1 cup sour cream
1/4 cup butter or margarine, melted
2 medium ripe bananas, mashed
STREUSEL:
1/4 cup sugar
3 tablespoons all-purpose flour
1/4 teaspoon ground cinnamon
2 tablespoons butter or margarine

DIRECTIONS
In a large bowl, combine the flour, sugar, baking powder, salt, baking soda and cinnamon. In a small bowl, beat eggs, sour cream, butter and bananas; stir into dry ingredients just until moistened. Fill greased or paper-lined muffin cups three-fourths full.
For streusel, combine sugar, flour and cinnamon in a small bowl; cut in butter. Sprinkle over muffins. Bake at 375 degrees F for 20-25 minutes.
