Preheat oven to 425F.
Combine plantain, olive oil, salt and coconut milk in a blender and blend on high for 1-2 minutes, until a completely smooth puree.
Invert puree into a mixing bowl. Add cassava flour and work into the puree until a sticky firm dough forms.
Divide dough into six and roll each part into a ball (about 2” in diameter). Place on a baking sheet. If desired, cut an ‘X’ with a sharp knife about ¼ “ deep at the top of each dough ball.
Bake for 25 minutes.
Remove from oven and let cool at least 5 minutes before serving.
