In a mixing bowl, combine the all-purpose flour, cornstarch, baking soda, melted butter, and a pinch of salt. Gradually add water while stirring, until you achieve a thick batter with the consistency of heavy cream.
¾ cup all-purpose flour, ¼ cup cornstarch, ½ teaspoon baking soda, 2 tablespoons melted butter, 1 pinch kosher salt
If the batter is too thick, add more water. If it's too thin, add more flour. Set aside.
½ cup water
In a deep skillet or frying pan, heat enough vegetable oil to submerge the banana pieces. Heat the oil to around 350°F over medium-high heat.
4 cups vegetable oil
Meanwhile, peel the bananas and cut them into bite-sized pieces; or slice them lengthwise.
2 ripe bananas
Dip the banana pieces into the batter, ensuring they are evenly coated.
Carefully place the battered banana pieces into the hot oil, and fry until they turn golden brown and crispy (about 2-3 minutes).
Use a slotted spoon to remove them from the oil and place them on a plate (or on a wire rack) lined with paper towels to absorb excess oil.
Serve while they are still warm. You can enjoy them as is or with a dusting of powdered sugar, a drizzle of honey, or a scoop of vanilla ice cream for an extra treat. Enjoy!
