Step 1

For the topping, in a medium bowl, mix flour, sugar and cinnamon. Add butter or margarine and mix with a fork or pastry cutter until crumbly. Put aside while preparing muffin batter.

Step 2

For the muffins, in large bowl, combine dry ingredients. Set aside.

Step 3

In another bowl, combine mashed bananas, sugar, slightly beaten egg and melted butter or margarine. Mix well. Stir into dry ingredients just until moistened.

Step 4

Fill greased muffin cups two-thirds full. (Do not use paper muffin cups!) Using hands, arrange coarse, pea-sized crumbs over muffin batter.

Step 5

Bake at 375 degrees for 18 to 20 minutes or until muffins test done with a cake tester. Cool in pan 10 minutes before removing to a wire rack.
