Heat about 2 inches vegetable oil in a large skillet over medium heat until a deep-fry thermometer registers 375°F.

Meanwhile, whisk the flour, baking powder, corn starch, salt, 1/4 teaspoon ground cinnamon, and the 1/2 cup granulated sugar in a large bowl.

Then whisk the egg, milk, mashed bananas, and 2 tablespoons vegetable oil in another bowl. Add the banana extract, if desired.

Combine the (2nd) 1/2 cup granulated sugar and 1 teaspoon ground cinnamon in a shallow bowl and set aside.

Mix the banana mixture into the dry flour mixture until moistened.

Working in batches, drop rounded 1/2 tablespoon of dough into the hot oil and fry until golden brown, about 15 seconds each side.

Remove with a slotted spoon, and drain on paper towels. Roll in the cinnamon sugar mixture while still warm.

Enjoy!
