• Begin by pouring roughly four inches of vegetable oil into a heavy pot and set it on medium heat. Use a deep-fry thermometer to keep track of the temperature, and place a large plate lined with paper towels nearby for draining.

For Fritter Preparation:

• In a medium bowl, mix together the mashed bananas, eggs, sour cream, melted butter, and vanilla extract until combined.
• In a separate bowl, whisk together the all-purpose flour, sugar, baking soda, ground cinnamon, and kosher salt.
• Gently merge the wet ingredients with the dry mixture until just combined, aiming for a thick batter consistency.

For Cooking Fritters:

• When the oil reaches 325°F, carefully place tablespoon-sized scoops of the batter into the hot oil. Fry them in small batches to avoid overcrowding.
• Cook the fritters, turning them gently until they achieve a golden brown color. This should take around 3 to 4 minutes.
• Using a slotted spoon, remove the fritters from the oil and place them on the paper towel-lined plate to absorb excess oil.
• Continue frying the remaining batter, ensuring the oil temperature stays at 325°F between batches.
• Finally, top the warm fritters with confectioners' sugar and a drizzle of caramel sauce before serving. Enjoy your delicious treat!
