Melt the butter in a large, non-stick pan over a medium heat, then add the sugar and cream, stirring until the sugar has dissolved. Bring to the boil, add the cinnamon, the vanilla extract and the bananas, turning them in the sauce to coat. Reduce the heat to low and cook for 3 minutes to slightly soften the bananas.
Warm the Flour Tortillas by following the instructions on the pack.
Place two banana halves on each tortilla, roll up and drizzle with caramel sauce. Serve with cream or ice cream.
If you're feeling slightly naughty (and youre old enough to vote), add a splash of tequila or rum to the caramel sauce!
