Mix the sugar and cinnamon and set aside.

Spread one flour tortilla with some of the Nutella. Top with sliced bananas. Then put a second tortilla on top like a sandwich. Brush both sides of the tortillas with the butter. Repeat with more tortillas, doing about one "sandwich" per person.

Heat up a skillet or griddle to medium high heat. Put each tortilla "sandwich" in the skillet and start to brown on each side. When they are almost brown, sprinkle some of the cinnamon sugar on each side and heat just long enough to melt the sugar.

Move to cutting board and cut into four wedges. Top with ice cream or whipped cream and a drizzle of some melted Nutella if desired.
