Preheat Oven: Preheat oven to 350°F (175°C). Line a loaf pan with parchment paper or lightly grease it.
Mash Bananas: In a bowl, mash the bananas until smooth.
Mix Ingredients: Add rolled oats and sweetened condensed milk to the bananas. Stir until fully combined. (For finer texture, blend oats into flour first.)
Transfer to Pan: Pour the batter into the prepared loaf pan and smooth the top.
Bake: Bake for 50–60 minutes, or until a toothpick inserted comes out clean.
Cool: Let it cool in the pan for 10 minutes, then transfer to a wire rack.
Serve: Slice and enjoy warm or at room temperature.
