First up, the banana filling:

• 1 tablespoon butter
• 1 medium banana, halved lengthwise
• 1/4 cup brown sugar
• 1 dash of cinnamon powder

For the paste:

• 1 tablespoon water
• 1 tablespoon all-purpose flour

For the wrapper and coating:

• 1 tablespoon refined sugar
• 1/4 teaspoon ground cinnamon
• 8 lumpia wrappers
• Vegetable oil

1. Melt the butter in a pan over medium-high heat.
2. Then, add in brown sugar and a dash of cinnamon. Mix this mixture well.
3. Add in the banana
4. Stir gently for 5 minutes until it turns brown.
5. Transfer the banana to a separate container and slice into small chunks (depends on how large you want the filling to be). Let it cool.
6. Next, whisk the water and flour in a mixing bowl to create the paste.
7. Add in refined sugar and 1/4 teaspoon cinnamon in a separate mixing bowl.
8. Place the lumpia wrapper on a flat surface and scoop 1 tablespoon of filling (again, you decide the size of the filling). Roll the lumpia wrapper. 
9. Smear the edge with the paste to seal in the lumpia wrapper. Set aside.
10. Repeat the process until you use up all the filling.
11. In medium high heat, heat 2 inches of oil in a deep pan.
12. Fry the cylinders in batches until they are golden brown. Ideally, 4-5 minutes.
13. Drain on a paper towel then sprinkle with your preferred sauce or topping.

You can even place a heaping scoop of ice cream on top of your turon ;) Some people sprinkle chocolate sauce or caramel sauce on top of the finished product. Enjoy!
