Cut the ends of the plantains, but leave the skins/peels on. Cut each plantain into 3 pieces.
Bring water to boil in a large pot. Add the ripe plantain pieces and cook for about 15- 20 minutes or until they are tender, but be careful not to overcook or they might be too mushy.
Let the ripe plantains cool down a little, but make the dough while the plantains are still warm. Save some of the plantain water in case you need it when making the dough.
When safe to handle, peel the plantain pieces and cut them in halves lengthwise, use a knife to remove the center seed core – this will result in a smoother dough.
Use a potato ricer to mash the ripe plantains into a smooth mix. You could also use a regular wood masher, a fork, or even a food processor.
Add the butter and mix well. If the ripe plantain mix is too dry you can add some of the water from the cooking process (add 1 tablespoon at a time). If the dough is too soft (happens with very ripe plantains), add in ¼ cup of precooked corn flour. Mix well and adjust either the liquid or the corn flour if needed.
Form the dough into a ball and let the ripe plantain dough cool down to room temperature.
Form the dough into small to medium sized balls, if you want to stuff them with cheese make a hole in the middle of each ball. This will need to be done gently as the ripe plantain dough is more fragile than the green plantain dough. Fill each hole with some grated cheese and close it while shaping it into a thick patty.
Let the patties rest in the fridge for at least 30 minutes or until ready to cook (optional).
Pre-heat the waffle maker and add the ripe plantain patties, if you can adjust the heat settings on your waffle maker, set it to 175C-180C or about 350F. The ripe plantain dough can burn very quickly so it is best to not use a high heat setting.
Cook the ripe plantain waffles for 5-7 minutes or until they are golden and crispy.
Carefully remove them from the waffle maker.
Serve the ripe plantain waffles topped with a fried egg and/or with extra cheese. You can also sprinkle some Ecuadorian sal prieta on top or some chimichurri sauce or your favorite hot sauce.
