Cream brown and white sugars with butter until very light and fluffy. Add eggs,
one at a time, beating well after each addition. Stir in mashed bananas. Sift
flour with baking powder and salt. Mix milk and vanilla together. Add each to
first mixture alternately. Stir in the pecans. Pour into a well greased 10"
