Mash bananas with a fork or puree them in a food processor or blender.
In a medium bowl, mix mashed bananas, flour, sugar, baking powder, and salt. Mix well to the consistency of a creamy batter.
Finally, add nutmeg and vanilla. Let rest for 10 minutes.
Pour about ½ inch of oil into a large skillet (cast iron is perfect), and heat on medium-high (375℉/190℃) until shimmering but not smoking.
Scoop the batter and fry it in batches until golden, turning once, about 5 minutes. Do not overcrowd the pan (it will cause the fritters to absorb excess oil and become soggy).
Using a slotted spoon, remove the fritters and place them on paper towels to drain. Serve warm.
