Banana Buttermilk Muffins

Directions

1. Preheat oven to 400°. In a bowl, cream butter and sugar. Add eggs, one at a time, beating well after each. Add bananas and vanilla; mix well. Combine the flour, salt, baking powder and baking soda; add to creamed mixture alternately with buttermilk.
2. Fill greased or paper-lined muffin cups two-thirds full. For the topping, combine the flour, brown sugar and oats. Cut in butter until crumbly. Sprinkle a rounded teaspoonful over each muffin.
3. Bake for 16-20 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing from pans to wire racks.
