Preheat oven to 350 degrees F. Grease and flour a 9x5 inch loaf pan. For a taller loaf, use a slightly smaller pan such as an 8x4 or 8 1/2 by 4 1/2.
Mix flour, baking powder, baking soda and salt together in a mixing bowl; set aside.
Beat cream cheese, butter and sugar until light and fluffy. Add bananas, eggs and vanilla and beat until mixed.
Add flour mixture and stir until it is almost mixed in. Add the ¾ cup of the pecans and stir pecans mixed and flour has disappeared - -batter should still be pretty lumpy.
Pour into pan. Toss remaining 1/4 cup pecans with cinnamon/sugar mixture and sprinkle over top. Bake at 350 for 1 hour and 10 minutes. Cool 10 minutes before removing from pan.
