Place the coconut flakes on a baking sheet and roast in the oven at 200 ° C for only a few minutes (be careful, it goes very quickly!).
Cut the bananas into thick slices and freeze for an hour, then roughly chop in the blender.
Add coconut milk, agave syrup and lime juice and process into a smooth mass in 1-2 minutes (the mass appears to flocculate at first, but then becomes smooth after a while). Fold in the roasted coconut flakes and enjoy immediately.
