Peel the overripe bananas and cut them into 1-inch pieces.

In a mixing bowl, combine the egg white, all-purpose flour, cornstarch, baking powder, and ice-cold water, whisk until smooth.

Fold the banana pieces into the batter, ensuring each piece is coated.

Heat 2-3 inches of vegetable oil in a deep pot over high heat.

Drop the battered banana pieces into the hot oil and fry for 2-4 minutes until golden brown.

Remove bananas with a slotted spoon and place on paper towels to drain excess oil.

Serve warm with optional toppings like powdered sugar or chocolate sauce.
