Step 1

Preheat oven to 350°F. Grease two 9-inch loaf pans. In a small bowl, combine sugar and cinnamon for the topping. Sprinkle generously over greased loaf pans (saving the remaining mixture for the tops of the bread). Set aside.

Step 2

In a large mixing bowl, beat butter with milk and sugar until blended. Add eggs and mashed banana and combine completely. Add flour, baking powder, baking soda, cinnamon, and salt. Mix just until blended.

Step 3

Pour evenly into loaf pans. Sprinkle with the remaining cinnamon sugar mixture. Bake for one hour.

Step 4

Remove from oven and cool in pans 10 minutes. Remove from pans and cool completely. Store in airtight container for several days, or freeze bread for later use.
