Simple to make and a great way to use up those last 2-3 overripe bananas! Always dependable & moist, and try substituting ingredients; regular milk for the buttermilk, half brown sugar for the sugar, chocolate chips for the raisins-the possibilities are endless. Not too sweet-my grandson has been making this since he was in a highchair at 1 year old.
Preheat the oven to 350 and spray a loaf pan with nonstick cooking spray.
In a large bowl peel and break the bananas into the bottom and mash with a potato masher or fork. Add the egg and vanilla and continue mashing.
Add the raisins and buttermilk or milk. Stir by hand with a wooden spoon until just incorporated.
Whisk the flour, baking powder, baking soda, sugar and salt together in a medium bowl and add to banana mixture in large bowl. Stir with wooden spoon only until mixed thoroughly-don't overmix.
Bake 45-50 minutes, or until a wooden pick comes out clean when inserted into middle of loaf, but don't overbake. Remove from oven and cool in pan on cooling rack 5 minutes. Invert and turn over onto cooling rack and cool another 5 minutes before serving warm.
