In a bowl, break up the bananas and mash them into a paste. Add in the rest of the ingredients except for vegetable oil (that's for frying them later). Mix everything until well combined, cover the bowl with a cling film and leave the batter to rest for 30 minutes.
Meanwhile you can prepare the oil for frying. Heat abundance of vegetable oil in a pot or a wok, use low medium heat. When the oil is hot, it's time to fry. Using your fingers, take some of the batter and kind of make it into a ball and carefully put in into the hot oil. This is the traditional way of doing it. You can spoon the batter and with the help of another spoon, put the batter in the hot oil. Don't over crowd the pot to prevent the oil getting cold and make the fritters oily.
Once the fritters float in the oil, start flipping them around. Continue until they're golden brown and fully cooked. Remove and place them on a kitchen paper to help absorb the oil. Best served hot. Enjoy!
