In a shallow bowl, mix the flour, granulated sugar, and ground cinnamon (if using).
Lightly coat each banana slice with the flour mixture, shaking off any excess.
In a large skillet, heat about 1/4 inch of vegetable oil over medium heat until hot.
Add the banana slices to the hot oil in a single layer, being careful not to overcrowd the pan. Fry for about 2 minutes per side, or until golden brown and crispy.
Remove the fried bananas from the skillet and place them on a paper towel-lined plate to drain excess oil.
Drizzle with honey or syrup, and garnish with fresh mint leaves if desired.
Enjoy your meal!
