Mash bananas and add to batter along with vanilla and pecans.
Be careful not to overmix.
Turn into a well greased pan and bake at 350 degrees for one hour.
Notes: This makes a very nice banana bread. I like to use the mini loaves and make 4 loaves and give them to friends. If you do this, cut the baking time to about 30 minutes. Be sure to check them early.
