Prepare 1/2 batch of ice cream according to directions, increasing egg yolks to 8 rather than 6. Place on a bowl of iced water to cool, stirring every few minutes. Prepared Bananas Foster according to directions, cool and puree in blender. Blend pureed bananas into ice cream base; lay plastic on top and chill.
Freeze ice cream base in ice cream freezer. Put graham cracker crusts into freezer to chill. Meanwhile, prepare caramel sauce according to directions.
Spoon a little of the cooled caramel sauce into chilled graham cracker crust and spread to a thin layer. Fill with frozen ice cream, cover with plastic and freeze.
When time to serve: Pull ice cream pies out of the freezer to soften at least 10 minutes before serving. Meanwhile, caramelize bananas and gently warm caramel sauce. Serve pies drizzled with caramel sauce and garnished with caramelized bananas.
*Note: this is a very sweet dessert, feel free to cut sugar in ice cream down to 3/4 or 1/2 cup.
