Make tortilla baskets:
Heat a lightly buttered saute pan, add tortilla and sprinkle with cinnamon sugar. When tortilla is hot flip over and sprinkle the other side with cinnamon sugar. Have ready 2 cups or small bowls. Remove the tortilla and quickly drape over the cup, placing the second cup over the tortilla to shape into a basket. Repeat method for the remaining tortillas. Set aside until ready to assemble.
In a saute pan, melt the remaining butter. Stir in the brown sugar, stirring until the sugar dissolves. Add the remaining cinnamon and bananas. Saute for 1 minute. Remove the pan from the heat and add the liqueur. Place the pan back over the heat and flame the liqueur. Shaking the pan constantly, cook for 30 seconds. Stir in the remaining 1/2 cup of cream and remove from the heat. Spoon the banana sauce in the center of each plate. Place the tortilla cup in the center of the sauce. Spoon the pudding in the center of the cups and top with a little more banana sauce. Garnish with powdered sugar and cinnamon sticks, if desired
