In a big bowl, mix all the ingredients in the Frying Batter together. Stir to mix well. Make sure the batter is smooth. Gently the bananas into the batter.
Gently drop each piece of banana into the hot oil. Deep fry the bananas in batches. Turn the bananas over so both sides turn golden brown in color and become crispy.
Repeat step 4 until bananas are used up. To serve, dust some powdered sugar on top of the bananas. You may also serve with maple syrup and chocolate sauce.
