In a blender, put ½ cup of cold fat-free milk, 1/2 teaspoon vanilla and 3 frozen bananas (chop them up prior to adding them).
Blend until smooth.
Add the pudding mix and blend again until no lumps remain.
Pour into freezer-safe container and stir in additional flavor options such as chopped nuts or chocolate chips if desired.
Freeze for several hours until firm. Enjoy!
