Preheat oven to 190 degrees.
Toss the chopped bananas with the lime juice and line at the bottom of a small baking pan. Sprinkle the dates, walnuts and cinnamon and the top.
Into the butter, add the oats and coconut and bring together with your fingers till it mixes well. Spread on the top of the fruit mixture. Bake for 30 minutes or till the top is golden brown. Allow the sizzle to settle and serve warm!
