Add the bananas to a blender or food processor and blend until smooth.
Add all the vanilla extract and ice cream and blend until smooth and frothy.
Serve immediately with vanilla wafers for dunking or add them right to the milkshake so they become soggy (one of the best parts about banana pudding)
Top with whipped cream if desired!
Notes
If desired for even more banana pudding flavor, you can add 1-2 Tablespoons of instant banana pudding mix. Also, if desired add a few vanilla wafers to the blender with the other ingredients.
