Add ¼ cup of milk to the microwave for about 7 seconds, until it is warm but not hot. Add 1 tsp sugar to the milk, then sprinkle the yeast on top. Set aside and allow to sit for about 10 minutes until the yeast starts to rise a bit.
Mash bananas. Add sugar and salt, then crack egg into the mixture and combine. Add flour and mix again. Finally, add in the yeast, and mash until everything is smooth. Let the mixture sit for about 20 minutes.
In a large pot or pan, heat about 1 inch of oil. The oil should be hot enough that if you sprinkle in some batter, it begins to bubble after a few seconds.
Use your hands or a spoon to scoop about 1 tbsp of batter into the hot oil, flipping when the fritters turn brown, then cooking on the other side. Test some of the fritters as you take them out of the oil… If the center is still raw, your oil is too hot.
Sprinkle with powder sugar or honey and enjoy!
