Preheat the oven to 170 Degrees Fahrenheit / 76 Degrees Celsius.
In a food processor or mixer, puree the ripe bananas and add 1 teaspoon of cinnamon powder.
Pour it into a baking tray lined with parchment paper or silicon mat.
Spread the banana puree evenly in a thin layer.
Place it in the oven for 3-5 hours or till the top is not longer wet to touch, is slightly tacky and the fruit leather peels off easily.
Cut the uneven ends with scissors and cut into strips. Roll it up or with a parchment paper in between.
Store it tightly wrapped in an airtight container.
Recipe Notes
If you want thicker fruit strips, you can pour the puree into a saucepan and stir it to let the water evaporate. Once the puree slightly thickens pour into the tray.
