Preheat your oven to 355 degrees F (180 degrees C).
In a large mixing bowl add Banana (5) and mash them up with a fork.
Next, add in Sweetened Condensed Milk (1 can), Self-Rising Flour (2 1/2 cup) and Ground Cinnamon (1 teaspoon). Give all the ingredients a good mix until just combined.
Grease a loaf pan with some spray on oil and line with parchment paper.
Pour your batter into the baking pan and smoothen out the top of the batter. Place into your oven and bake for 45-50 minutes or until a skewer inserted into the center of the banana bread comes out clean.
Remove the banana bread from the oven and leave in the pan for another half an hour, then remove and place onto a wire rack to cool completely.
