Whisk bananas, eggs, and milk together in a medium bowl.

In a separate bowl, combine flour, sugar, baking powder, and salt.

Pour the flour mixture into the banana mixture and stir until just combined; batter will be thick.

Pour vegetable oil into a medium saucepan or skillet to a depth of 1 inch.

Heat oil over medium-high heat until hot.

Drop heaping tablespoons of batter into the hot oil, frying 2-3 fritters at a time.

Fry for 1-2 minutes per side, or until golden brown, adjusting heat as needed to prevent burning.

Remove fritters and place them on a paper towel-lined plate to drain excess oil.

Continue frying the remaining batter.

Serve warm, sprinkled with icing sugar or maple syrup, or with a scoop of vanilla ice cream.
